Temperal and spacial analysis for catches have been drawing up a catch distribution chart and analysing catches and CPUE(Catch Per Unit Effort) using catch data with purpose of obtaining basic data to establish a selective method of effective fishing the tuna purse seine fishing ground.The temperature profile section and catch was surveyed to analyse the effect of catch in relation to the fishing ground environment.The results are as follows ;1. As for the catch variation between 1983 and 1984, the catch mainly took place on150^{\circ}E$, and after that it moved eastward enlarging the range of catch. In the monthly catch variation between January and February, the catches mainly happened on 135$^{\circ}$~ 150$^{\circ}$E, and then moved to the gradually westward. However, from July it moved to the South and from October Southeast.2. As to the eatch ratio for the school associated with the drifted object, the pelagic migrating school and the school associated with the biological objects, the catch ratio for the school associated with the drift objects was the highest. The catch ratio for the school associated with the drifted object was high in June, July and November whiles between January and March for the pelagic migrating school.3. SST(Sea Surface Temperature) was around 28~29^C$ on the observing line of 137^{\circ}E$ and the catches took place in the north equatorial counter-current situated on around $5^{\circ}~6^{\circ}N$. SST in the northern summer was 1^C$higher than winter and it was about 29~30^C$. The catch happened with the center of north equatorial counter-current. The reason why the catch mainly took place on the north equatorial counter-current is that main catch of tuna purse seine was the school associated with drift objects. It is thought that the fishing grounds are made in waters that have many drift objects like drift logs from the coast.

Despite the increasing importance that companies currently place on employee wellness, few studies have explored the impact of wellness on individual and team performance in the workplace. Drawing on the broaden-and-build theory, we hypothesize that wellness intention, wellness leadership, and wellness climate influence the performance of both individuals and teams. We tested our hypotheses using data collected from 495 employees of 81 teams in 11 Korean companies. Our analysis indicates that wellness leadership and wellness climate are meaningful interventions between perceived wellness and performance. Wellness intention did not impact perceived wellness. However, the interaction between wellness intention and wellness leadership impacted perceived wellness. Wellness climate negatively moderated the relationship between perceived wellness and performance.

As PB market segments into premium market, PBs were drawing attentions in terms of creating profits as well as a means to differentiate building up store identity. The purpose of this study makes a comparative study on the difference of consumer attitude formation process in discount store and home-shopping distribution channel which are recently on the upswing. This paper investigated the consumer's attitude formation on the private apparel brand. Subjects of this study were consumers in their $20s{\sim}40s$ who are main customer groups of PBs. The data were analyzed by Structural Equation Modeling and Multi-Group Analysis of Amos 5.0 to verify the difference of the path between store PB and premium PB. Following are the results of the study. Consumer attitude formation path on PB grades showed statistically noticeable difference. In discount store PB, store evaluation didn't directly influence on consumer attitude formation but showed indirect effect. On the other hand, in home shopping premium PB case, product evaluation directly influenced on consumer attitudes with store evaluation. Hedonic attitude dimension connected with behavioral attitude(purchase intention) revealed difference in path. Also consumer's evaluation on variables in model turned out to be different according to brand grade.

It may be replacement proofs with understanding and explaining geometrical properties that was a remarkable change in school geometry of 2009 revised national curriculum for mathematics. That comes from the difficulties which students have experienced in learning proofs. This study focuses on one of those difficulties which are caused by the forms of proofs: using letters for designating some sides or angles in writing proofs and understanding some long sentences of proofs. To overcome it, this study aims to investigate the applicability of Byrne's method which uses coloured diagrams instead of letters. For this purpose, the proofs of three geometrical properties were taught to middle school students by Byrne's visual method using the original source, dynamic representations, and the teacher's manual drawing, respectively. Consequently, the applicability of Byrne's method was discussed based on its strengths and its weaknesses by analysing the results of students' worksheets and interviews and their teacher's interview. This analysis shows that Byrne's method may be helpful for students' understanding of given geometrical proofs rather than writing proofs.

This study was performed to develop dietary education programs for children, by researching the actual conditions of dietary education and its demand aimed at teachers in child centers in Masan. Most of the interviewed teachers were in their 20s(71%) with under 5 years teaching experiences(56.8%), and working in a kindergarten environment(34.9%). The rate of doing dietary education on mealtime was 96.4%. The main items taught pertained to 'not leaving food(20.6%)' and 'washing hands before meals(20.5%)'. The primary teaching method for students with unbalanced eating habits was 'eating after teaching them to understood(76.8%). The primary reward for good behavior was 'using food(76.8%)', usually as 'candy'(50.8%) or 'cookies'(25.8%). The desirable dietary education type was 'during spare moments(52.6%)' and 'at mealtime (23.5%)'. The concepts taught were 'balanced eating(23.2%)' and 'food hygiene(21.2%), and the students were interested in 'the roles of foods and nutrients'(34.5%), 'balanced eating(20.9%)', and 'food hygiene(19.1%)'. Educational activities encompassed 'pictures and drawing(25.7%)', 'fairy tales(23.4%)', 'songs(19.4%)', and 'play(14.1%)'. Also, the activities of most interest were 'fairy tales(29.4%)', 'play(24.4%)', and then 'songs(23.1%)'. The greatest difficulties during dietary education were 'attracting interest from the children(37.8%)' and 'making and purchasing materials(33.9%)'. Approximately, 44.2% of the teachers had experiences in dietary education, and 96.4% stated teachers had the intention to participate in dietary education. They want to address 'child meal direction(23.0%)', 'health problems(22.7%)', and then 'child nutrient requirements (17.3%)'. Also the majority wanted it two times per year(57.6%) or one time per year(30.9%). This study indicated that proper dietary education must be established in child centers by developing various practical dietary education programs and then implementing them.

The purpose of this study was to analyse characteristics of explanatory writing of scientifically gifted students who participated in gifted educational programs. Considering aspect of content of their explanations about cell, many of them explained the common characteristics of animal and plant cells, but a few of them did cellular characteristics of one kind of animal and plant. Some gifted students regarded cell membrane function as that of cell wall, and had a misconception that the cell was the smallest unit to consist human body. In terms of the structure of explanation, most of them didn't know the structural characteristics of explanatory writing. Finally, more than 50% of them had written using various ways to explain cell such as classifying, comparing, contrasting and exemplifying. Especially, all biologically gifted students had creatively explained drawing a picture. It was findings that the explanatory writing could be used as the instrument to evaluate knowledges of gifted students and suggested the elements of writing to teach scientific explanatory writing.
