AbstractHuman resources are the most important elements of economic units; thus, the efficiency of human work is of crucial importance. Work efficiency can be achieved only in an environment offering optimal thermal comfort. The present study makes use of human subject experiments in order to investigate the joint effect of draughts and warm ceilings on work performance. During the experiments, 10 thermal environments with 5 radiant thermal asymmetries and 2 draught rates were investigated. The most important outcome of the research is the presentation of the combined effect of a draught and a warm ceiling on work performance.

For buildings with ceiling heating and mechanical ventilation, it is extremely important to know the combined effect of the draught and the radiant thermal asymmetry caused by a warm ceiling. There is plenty of literature offering separate descriptions of the dissatisfaction caused by draught and warm ceilings, but research on the combined effect of these two local discomfort factors is incomplete. In order to fill in this gap, human subject measurements were conducted involving 20 subjects, 10 men and 10 women, who were asked to complete questionnaires on thermal sensation, while being exposed to a random combination of 5 asymmetries and 2 draughts. Analyzing the results obtained this way made it possible to evaluate the combined effect of the draught and radiant thermal asymmetry on thermal comfort. The most important outcome of the research is the mathematical description of the expected dissatisfaction rate and the presentation of the differences depending on gender.

Abstract Background To investigate the combined effect of hypertension and hyperuricemia to the risk of ischemic stroke in a rural Chinese population. Methods The cross-sectional study was conducted from 2012 to 2013 in a rural area of China. After exclusion for missing data, we finally included 11,731 participants into analysis. Results After adjusting for age, current smoking, current drinking, BMI, TG, HDL-C and eGFR, hypertension was significantly associated with ischemic stroke in men (OR: 2.783, 95% CI: 1.793, 4.320) and in women (OR: 4.800, 95% CI: 2.945, 7.822). However, hyperuricemia was significantly associated with ischemic stroke only in women (OR: 1.888, 95% CI: 1.244, 2.864). After full adjustment, participants with both hypertension and hyperuricemia had 8.9 times higher risk than those without them. Finally, the interaction between hypertension and hyperuricemia was statistically significant only in women rather than in men after full adjustment. Conclusions This study demonstrated the positive correlations between hypertension, hyperuricemia and ischemic stroke. Our study also demonstrated the joint effect between hypertension and hyperuricemia towards ischemic stroke only in women, not in men.

The purpose of this study was to determine the system for placing employees in structural positions as well as the determinants of the placement of employees in structural positions in the Personnel and Human Resources Development Agency of Southeast Minahasa Regency. Data collection techniques were collected through 1) Observation, 2) Interviews, 3) Documentation. The research results are the Employee Placement System in Structural Positions through a standard mechanism, namely using Government Regulation Number 11 of 2017 concerning the Management of the State Civil Apparatus. Placement of employees in structural positions is carried out based on the principle of professionalism by the competence, work performance, ranks assigned to the position as well as other objective requirements regardless of gender, ethnicity, religion, race, or class as well as the Determinant Factors on Employee Placement, namely: 1) Academic Achievement, 2) Experience, 3) Physical and Mental Health, 4) Marital Status, 5) Age.

Urban Heat

Urbanization has influenced the distribution of heat in urban environments. The mutual influence between weather factors and urban forms created by dense buildings intensify human perception of the deteriorating thermal environment in subtropics. Past studies have used real-world measurements and theoretical simulations to understand the relationship between climate factors and the urban heat island effect. However, few studies have examined how weather factors and urban forms are connected to the thermal environment. To understand the influence of various weather factors on urban thermal environments in various urban forms, this study applied structural equation modeling to assumptions of linear relationships and used quantitative statistical analysis of weather data as well as structural conversion of this data to establish the structural relationships between variables. Our objective was to examine the relationships among urban forms, weather factors, and thermal comfort. Our results indicate that weather factors do indeed exert influence on thermal comfort in urban environments. In addition, the thermal comfort of urban thermal environments varies with location and building density. In hot and humid environments in the subtropics, humidity and wind speed have an even more profound impact on the thermal environment. Apparent temperature can be used to examine differences in thermal comfort and urban forms. This study also proved that an urban wind field can effectively mitigate the urban heat island effect. Ventilation driven by wind and thermal buoyancy can dissipate heat islands and take the heat away from urban areas.
