Abstract The article deals with the historic buildings and their insulation. It is generally known that classical thermal insulation of walls from the outside is not permissible due to the cultural value of historic facades. Compared to external insulation solutions, the implementation of internal insulation is more technically complex and faces several risks. In the article is devoted the chapter which deals with the aim of the application of internal insulation in historic buildings. There are mentioned risks associated with the application of internal insulation, which are related to the thermal-humidity behaviour of the structure. One chapter is devoted to faults that may occur after the application of internal insulation. These disorders have a building-physical character and also affect the hygienic criteria of the building. The larger chapter deals with insulating materials suitable for the purposes of interior insulation of historic buildings. The results of a case study from Dublin and Košice are also presented, where the thermal-humidity behaviour of selected thermal insulation materials was investigated. The results of moisture content and surface temperature before and after application of insulating materials are compared.

Pine, birch, and cotoneaster wood chips were segregated and exposed to microwave radiation. Moisture content was measured before and after microwave treatment, and the surface temperature of wood chip samples was recorded. The results showed that due to the selective nature of the process, the duration of microwave radiation should be adjusted taking into account the size fraction of the examined material. Wood chips exposed to microwaves for more than 30 s heated up to over 100 °C. Finer wood chips were found to lose moisture more slowly.

This case study examines and illustrates within country regional cultural differences and cross border cultural similarities across four western European countries. Drawing on the data from the World Values Survey (WVS), we refer to the Schwartz Cultural Values Inventory in the survey. The demographic variables of age, gender, education level, marital status and income vary across the regions and hence, have significant effects on the cultural value dimensions across regions. The findings help a better understanding of the homogeneity and heterogeneity of regions withinand across countries. Both researchers and managers will have to justify their sampling methods and generalisations more carefully when drawing conclusions for a whole country. This case study underlines the limited knowledge about regional within country cultural differences, while also illustrating the simplification of treating each country as culturally homogeneous. Cross-country business strategies connecting transnational regional markets based on cultural value characteristics need to take these similarities and differences into account when designating business plans.

The Financial Master Plan (2001- 2010) aims to enhance the capacity of banking industry so that higher effic iency and productivity can be reaped in the future. This study seeks to determine the impact of merger on the efficiency and productivity ofcommercial banks in Malaysia for the period 1995 until 2005. The study uses a non-parametric approach, nam ely DEA (data envelopment analysis?) to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs are used. Amongst the findings are those banks exhibit higher efficiency score after the merger and thefo reign banks are more efficient than the local banks. Productivity of the banks is calculated in both periods, before and after the merger: The results show that, it is the local banks that have improved the most after the merger. The main source of productivity is technical change or innovation. The findings support the existing policy of having larger domestic banks in term of size.

Study the effectivity analysis of Program Usaha Agribisnis Perdesaan (PUAP) and its impact on farmer income levels (case study of the Teluk Jaya Farmers Group Association) aims to 1. knowing how large the effectivity of PUAP funds is for income levels in poverty alleviation in Teluk Desa Sentosa Panai Hulu Subdistrict, 2. to analyze and determine the level of income of Gapoktan Teluk Jaya Farming Business in Teluk Sentosa, Panai Hulu Subdistrict before and after receiving PUAP assistance. The results showed that the effectivity of PUAP program funding is very effective and good, it can be seen from the results of the F test of 12.406 with a significant level of 0.000 while the F value of the table is 2.051. When compared to the value of F test (12.406) > Ftable (2.051) at α 5%, it was concluded that simultaneously the effectivity variable and the PUAP program had a positive effect. The increase in income of the Teluk Jaya Farmers Group in Teluk Sentosa after receiving PUAP funds can be known from the t table for the effectivity variable of 2.663 and the PUAP program for 1.270 with a significant value for each independent variable (2.051); (0.073). Whereas for the t table value in the distribution statistics t table with the level of test α = 5% and df1 = 27 of 2,051. Based on the criteria that if the value is t count> t table); namely (2.663> 2,051) (1,270> 2,051) so that it can be concluded that the effectivity variable partially has a positive and significant effect on the income level.Keywords : effectivity variable,  income level, PUAP program

Aim: This study explores the changes in regular walking activities during the phases of the pandemic. Background: With the spread of COVID-19 transmission, people are refraining from going out, reducing their physical activity. In South Korea, COVID-19 broke out in the 4th week of 2020 and experienced the first cycle phases of the pandemic, such as outbreak, widespread, and decline. In response to the pandemic, the government encouraged voluntary participation in social distancing campaigns, and people reduced their outside activities. Methods: This article examines the decrease and increase of the Prevalence of Regular Walking (≥30 min of moderate walking a day, on ≥5 days a week) by the COVID-19 phases. This study is based on weekly walking data for 15 weeks in 2020, via the smartphone healthcare app, which is managed by 25 public health offices of the Seoul government. Results: According to the findings, the level of prevalence of regular walking (PRW) has a significant difference before and after the outbreak, and every interval of the four-stage COVID-19 phases, that is, pre-pandemic, initiation, acceleration, and deceleration. The level of PRW sharply decreased during initiation and acceleration intervals. In the deceleration interval of COVID-19, the PRW kept increasing, but it has not yet reached the same level as the previous year when the COVID-19 did not exist. Conclusions: As a preliminary study, this study explains empirically how COVID-19 changed PRW in Seoul. It would be helpful to enhance our understanding of the changes in physical inactivity in the pandemic period.

Buildings of heritage significance due to their historical, architectural, or cultural value, here called historic buildings, constitute a large proportion of the building stock in many countries around the world. Improving the performance of such buildings is necessary to lower the carbon emissions of the stock, which generates around 40% of the overall emissions worldwide. In historic buildings, it is estimated that heat loss through external walls contributes significantly to the overall energy consumption, and is associated with poor thermal comfort and indoor air quality. Measures to improve the performance of walls of historic buildings require a balance between energy performance, indoor environmental quality, heritage significance, and technical compatibility. Appropriate wall measures are available, but the correct selection and implementation require an integrated process throughout assessment (planning), design, construction, and use. Despite the available knowledge, decision-makers often have limited access to robust information on tested retrofit measures, hindering the implementation of deep renovation. This paper provides an evidence-based approach on the steps required during assessment, design, and construction, and after retrofitting through a literature review. Moreover, it provides a review of possible measures for wall retrofit within the deep renovation of historic buildings, including their advantages and disadvantages and the required considerations based on context.
