This study is a basic research in purse seine fishery : on the behaviour of fish schools of tilapia Tilapia mossambica in the process of catch of the purse seine fishing method. The experiment was carried out for the mackerel purse seine which using of power block by fishing fleet system in the near sea of Cheju Island and as a forecast in the near future on the purse seine fishing, using of triplex net winch by one boat system in the near sea of Norway. These model purse seines were made of the scale of 1/180 of its full scale. The model purse seine test on the escaping behaviour of fish school by gap, area reducing of gap and tension of purse line was carried out in the stagnant water of experimental water tank. Designing and testing for the model purse seines were based on the Tauti's law. The results obtained were as follows : 1. When the time for the completing of pursing was 20 minutes, average swimming speed of fish school through a gap was 9.71cm/sec for powerblock seine and 9.97cm/sec for triplex seine. 2. In the case of pursing time in actual value was 20minutes, at 50 percent of the pursing, swimming behaviour of fish school in purse seine was 10% to I section, 80% to II section, 10% to III sectional direction for powerblock seine and a similar tendency for triplex seine. 3. In the case of pursing time in actual value was 20 minutes, at the time of 10 minutes have proceeded since then, area reducing rate of gap of the seine in projected front view was 63.5% for powerblock seine and 67.5% for triplex seine. 4. In the case of pursing time in actual value was 20 minutes, escaping rate of fish school by gap in projected front view was 70% for powerblock seine and 30% for triplex seine. Maximum tension of purse line was about 8.1 tons for powerblock seine and about 8.3 tons for triplex seine.

오늘날 수중가청음을 이용하여 어류의 유집과 구집에 많은 활용도를 보여주고 있다. 어류는 소리에 대하여 민감한 반응을 보이는데, 대표적으로 천적이 내는 소리에 의한 도피 행동, 같은 어류가 내는 식이음에 따른 색이 행동, 그리고 음원 주변에 모이는 유집 행동 등이 있다. 소리는 내는 어종들은 여러 수종이 알려져 있으며, 어류의 가청범위는 16∼13,000Hz 범위에서 가장 민감한 반응을 나타낸다고 한다.(전촌; 1977, 김;1981) (중략)

수산자원의 현존량을 추정함에 있어, 계량어군탐지기(이하, 계량어탐 이라 한다)를 이용한 음향자원량 조사는 넓은 수역을 단시간에 조사 가능한 효율적인 방법으로서 확립되어 있다. 한편, 최근에 멸치, 꽁치 등의 표층어종의 자원량조사의 필요성이 높아지고 있지만, 계량어탐은 수직 빔을 이용하므로, 표층의 탐지범위가 좁고, 어군의 선체도피행동이나 표층 데드죤이 존재한다. 그 때문에, 표층을 광범위하게 탐지 가능한 소너를 이용한 자원량 추정법의 개발이 요구되고 있다. (중략)

본 연구는 선우휘의 <불꽃>을 중심으로 그의 작가의식을 연구한 것이다. 논의 결과를 요약하면 다음과 같다. 첫째, 선우휘의 소설에는 현실도피와 역사의식의 부재가 있다. 둘째, 그는 반공주의에 깊게 영향을 받았다. 셋째, 역사적 각성이 제거된 행동만을 보여준다. 넷째, 냉전 이데올로기에 따른 국가주의에 순응한다. 이런 점에서 그는 반공 이데올로그로 볼 수 있다.

어류양식은 제한된 사육조건 때문에 외적으로 가해지는 환경스트레스에 대해서 도피 등 어류의 보상행동은 제약을 받게되고 생체기능 또한 순응 또는 저항 등의 형태로 보상적 반응을 보이게 된다. 우리나라의 육상 수조식 어류양식은 연중 수온의 변동 속에서 이루어지고 있다. 따라서 자치어기와 성어기의 양성기간에 계절적 수온 변화를 경험하면서 수온에 순화되어 성장하고 있다. (중략)

This study was based on the 'Escape Theory' model suggested by Baumeister(1990). Based on this analysis framework, this study attempted to examine that complicated direct and indirect effect of school risk factors(risk of academic scores, risk of relation with teacher and risk of peer relation) on suicide ideation in adolescence, through negative self-esteem, depression and withdrawal coping. To this end, this study used the data from the '2008 Gyeongsangbuk-Do youth crisis survey' conducted by the Youth service center in province of Gyeongsangbuk-Do. The target number of this study was 2,335 students in the age group of middle school and high school. The result of the Analysis indicate that risk of relation with teacher among school risk factors was only one which affected directly and indirectly on suicide ideation. The other side, risk of academic scores and risk of peer relation had indirect effects, via negative self-esteem, depression and withdrawal coping. In conclusion, this study confirmed that school risk factors had effects on suicide ideation directly or indirectly, they were complicatedly connected, through negative self-esteem, depression and withdrawal coping. Therefore, Prevention program for adolescence' suicide ideation or suicide risk require integrated strategies and tactics.

The purpose of this paper is to examine the structural relationship between experience(4Es), customer commitment and behavioral intention based on experience of the theme park as a hedonic destination. To carry out this study objective, a survey targeted for theme park customers was conducted from May 10. 2014 to June 10. 2014. These data were processed using SPSS 18.0 and Structural Equation Modeling with Amos 18.0 to test proposed hypotheses. The results are summarized as followed. First, the decomposition of path analysis revealed significant positive effects on customer commitment by entertainment experience, education experience, esthetic experience. and escape experience. While, entertainment experience was shown to have the largest influence on customer commitment. Second, customer commitment had a positive effect on revisit intention and WOM. Third, experiences have an indirect influence on revisit intention and WOM through the mediation of commitment. From the findings, the theme park is necessary to plan and develop experience program for more variable and special.

The purpose of this study was to identify the experience factors (4Es) of live commerce that provide differentiated value for consumers based on Pine & Gilmore's experience economy and analyze the relationships between experience factors, flow, attitude, and purchase intention. This study conducted an online survey to collect live commerce user responses and employed a path analysis to test the research hypotheses, using Smart PLS 4.0. The results of the study were as follows: 1) all experience factors had significant effects on flow, 2) both entertainment experience and educational experience had significant effects on attitude, while esthetic experience and escapist experience did not have significant effects on attitude, 3) flow had a significant effect on attitude and purchase intention respectively, and 4) attitude had a significant effect on purchase intention. The findings of the study are expected to provide the implications for further research and marketing strategies grounded on the understanding of the experience factors in live commerce.
