Authors in this paper presented the analysis regarding influence of deck equipment positioning and trimming, which is directly connected with sails, on sailing yacht performance in sailing. The analysis is performed by on-field measuring during sailing using specialized equipment based on RaceQs application and GPS support. The analysis is related to light wind conditions without significant waves, then to moderate wind and waves and finally to storm wind and high waves. Data collecting was performed during 30 hours of measuring and monitoring where the relevant equipment was continuously repositioned and trimmed aiming to reach more boat speed for different sailing angles. The results are processed and presented. The research was enabled with help and support of Bavaria Yachts d.o.o. Further analysis is suggested for different wind conditions and sea states.

For most sailing yachts, losing a rudder is probably the most catastrophic structural failure other than losing the keel. Rudder failure happens with distressing regularity. This paper examines the hypothesis that the underlying reason is design failure. There are many qualitative decisions to be taken in the design calculation process. Example calculations are presented which show that the maximum rudder force generated in steady state conditions is easily underestimated. For a typical spade rudder of a typical modern production sailing yacht, the normal rudder force should be calculated using a boat speed of at least 125% hull speed, and a force coefficient of at least 1.3. Care must be taken in selecting an appropriate value for the allowable stress of the material used for the stock.

Morphological Differences

This research discusses the differences of vowel correspondences, vowel, and  consonant variations of Tulangbawang dialect of Lampung language in six research areas. The data collecting technique was conducted by applying  dialectology method. Moreover, this research used the list of questions  that  listed in Swadesh’s basic vocabularies. The result showed that there are  differences in the linguistic elements in Lampung language which include  the  differences in phonology, morphology, and lexicon. In the phonological differences, it was found that there are one vowel correspondence, eleven vowel variations, and twenty three consonant variations. In general, vowel correspondence lies in the end of words, and the tendency of occurring is found  in the research area 1, 3, 4, and 5. All research areas always have similarities  but there are various changes for each correspondence in research area number  six. In the morphological differences, there are differences in the form of suffixes namely correspondences. Besides, there are some lexical differences found in the six research areas.Abstrak Penelitian ini membahas perbedaan korespondensi vokal, variasi vokal, dan variasi konsonan dalam bahasa Lampung dialek Tulangbawang di 6 titik pengamatan. Pengambilan data dilakukan dengan menggunakan metode dialektologi. Selain itu, penelitian ini menggunakan daftar pertanyaan yang digunakan pada 200 kosakata dasar swadesh. Ditemukan perbedaan unsur-unsur kebahasaan dalam bahasa Lampung yang meliputi perbedaan; fonologi, morfologi, dan leksikon. Perbedaan fonologi ditemukan satu korespondensi vokal, sebelas variasi vokal, dan dua puluh tiga variasi konsonan. Umumnya korespondensi vokal posisi akhir kata, ada kecendrungan pada daerah titik pengamatan 1, 3, 4, dan 5. Kesemua itu selalu memiliki kesamaan walaupun pada enam daerah titik pengamatan memiliki perubahan yang berbeda-beda untuk setiap korespondensi yang ditemukan. Dalam perbedaan morfologi terdapat perbedaan bentuk sufiks yang berupa korespondensi. Selain itu, perbedaan leksikon cukup banyak ditemukan pada enam titik daerah pengamatan.

Abstract This research aims to determine the effectiveness of the implementation of Play Therapy through Imaginative Pretend Play technique in Handling Cases Agresive Behavior Child Victim of Sexual Abuse. The Agressive behavior that are refered in this research are divided into two; Phyisic aggresive and verbal agressive. The methode in this reserach is Single Subject Design with A-B-A-B. Data collecting technique conducted by observation, unstructur interviews, documentary study and filling questionaire. All the measurment using this research are formed.  The result showed that the aplication of Imaginative Pretend Play technique in Handling Cases Agressive Behavior Child Victim of Sexual Abuse is effective to reduce the agressive behavior frequencty of child. The frequency of physical agressive that consist of  hitting, wresting, throwing, threat with showing and imitating sexual adult activity  decresed from 39 before intervention to 11 after intervention. The frequency of verbal  agressive that consist of  bellowing, mocking and speaking with dirty word decresed from 39 before intervention to 11 after intervention. The result of ECBS show intervention influence to cognition aspect significantly, intervention influence to social relation aspect significantly and intervention influence to self adjustment aspect significantly.Keywords: Child, Sexual Abuse, ECBS, Imaginative Pretend Play, Play Therapy Abstrak Penelitian ini bertujuan untuk mengetahui efektifitas Play Therapy melalui teknik Imaginative Pretend Play dalam menangani masalah perilaku agresif anak korban kekerasan seksual.

Main Activity

The paper describes how to determine the noise in a production hall where there are production machines and equipment. The chosen plant is a production unit where filling of the polyurethane foam tubes is performed. The main activity is the production of professional insulators and wholesale of other products from the same range enumerating the following: wholesale chemical products; production of professional insulators; trade in chemicals and chemical industry. The recommended maximum admissible value for a normal 8h work program is 85 dB (A). The objective is to determine the level of noise in the factory and how it acts as a physical professional risk factor and its effects on the human body. The way in which the proposed objective was achieved was to determine the value of the noise level with the specialized equipment. Following the determinations that will be presented in the following chapters, appropriate protective measures have been taken.
