본 연구에서는 강한 한파가 발생했던 2018년과 온난 한파가 발생했던 2019년의 기온에 따른 수온의 반응 및 지연시간과 북풍계열 바람 빈도와의 상관관계를 분석하였다. 사용된 시간 자료는 국립수산과학원에서 제공하는 7개 지점 해역별 수온자료와 수온관측소 인근 7개 지점 AWS 기온자료를 이용하였다. 관측되지 못한 자료는 내삽법으로 근사값을 계산하였고, FIR Filter를 이용하여 자료의 주기성을 파악하였다. 그 결과, 강한 한파가 발생했던 2018년은 북풍계열 바람을 통해 차가운 공기가 남하하면서 기온을 하강시켜 전 해역에 저수온을 유발한 반면 온난 한파가 발생했던 2019년은 평년 수준의 기온으로 하강하였지만 수온은 크게 변화하지 않았다. 강한 한파가 발생했던 2018년 기온 하강에 따른 수온의 지연시간은 평균 14시간으로 0.7 이상의 높은 상관성을 나타냈고 온난 한파가 발생했던 2019년은 평균 지연시간이 20시간으로 0.44-0.67 사이의 상관성을 보였다. 본 연구를 통해 해역별로 기온 하강에 따른 표층수온의 반응을 해석하였고 지연시간을 파악함으로써 양식생물의 피해를 최소화하고 한파 피해의 신속한 대응에 기여할 수 것으로 기대한다.

2020년 3월부터 10월까지 군산시의 중초산 저수지와 북초산 저수지의 어류상 및 군집분석을 하였다. 조사기간 동안 채집된 어류는 중초산 저수지에서 4목 5과 8종 1,895개체, 북초산 저수지에서 3목 5과 7종 171개체였다. 중초산 저수지의 우점종은 참붕어(661개체, 상대풍부도: 34.7%) 아우점종은 흰줄납줄개(660개체, 상대풍부도: 34.7%), 북초산 저수지는 배스(77개체, 45.0%)와 붕어(60개체, 35.1%) 순으로 나타났다. 군집분석 결과 중초산 저수지는 우점도 0.697, 다양도 1.483, 균등도 0.713, 종 풍부도 0.928, 북초산 저수지는 우점도 0.801, 다양도 1.304, 균등도 0.670, 종 풍부도 1.167을 보였다. 본 연구 결과를 통해 생태계 교란생물인 배스의 영향으로 토착어종의 개체수와 군집의 다양도가 감소한 것을 확인할 수 있었다. 따라서 외래어종의 지속적인 제거와 유입을 막는 관리가 요구된다.

This research is to investigate the perception and satisfaction of high school students for Saenghwal Hanbok school uniforms. With this study we will be able to provide useful information for clothing companies as well as schools which are planning to introduce Saenghwal Hanbok as a uniform. The research subjects included 446 high school students of Chungcheong and Gyeonggi areas. The results of this study are as follows: 1. Male students evaluated Saenghwal Hanbok affirmatively in terms of its activity convenience. Female students, on the other hand, thought highly of it in such aspects as modern beauty, aesthetic color, distinction, symmetry, wearability, tidiness, color harmony, color unity, decoration details, and suitability for special occasions as well as modem daily life. 2. The satisfaction with Saenghwal Hanbok as a school uniform stayed, on an average, below a mid-level. It appeared that high schools with long history showed more interest than comparatively newly-established schools. Also, students with obesity liked Saenghwal Hanbok more than normal students. 3. The students' demand for price cut was highest among other demands of Saenghwal Hanbok school uniform. In addition, almost all items including wearability, material, color, activity convenience, and patterns appeared to need more improving.

The purpose of this study is to provide useful footwear information for manufacturers and teenagers so that they can produce or purchase proper footwear that would minimize discomfort. For this study, 486 junior high school students were surveyed with a questionnaire. SPSS WIN10 was used to process a statistical analysis such as ferq., factor analysis, t-test, ANOVA(LSD), crosstab, and coefficient correlation. The results are as follows: A significant difference existed between male and female students in purchasing footwear and using evaluation criteria. When they wear shoes for a long time, they usually experience numbness in toes, blisters, heel, bottom on the feet and peeled skin. Female students experienced more foot injuries than males. There were meaningful correlations among purchasing, evaluation criteria, and satisfaction of footwear. Providing proper information is believed very important for teenagers in choosing right footwear. Footwear manufacturers should help them produce suitable shoes, and further help them establish different marketing strategies. To ease the foot discomfort, shoes should be developed with various widths and sizes. Shock absorbing soles and more flexible materials are also necessary.

Survey was conducted on 201 female college students who in at the university to analyze perceptions and satisfaction levels about their body shapes. Results revealed that the Chinese female students recognized that they had broader shoulder angles, bigger breasts and longer calves and legs than Korean female students whereas the Korean female students had larger hip and thigh circumference than Chinese female students. It was found that the Chinese female students had preference for drooping shoulders while the Korean students perceived themselves as thinner and have longer arms, fingers, waist measurement, torso thickness, calves, feet and legs are ideal body shapes. The results of this study show that body weight, height and chest size have a lot of influence on it and the Korean female students were less satisfied their body shape compared with the Chinese female college students. The correlation analysis indicated that body shapes were an important indicator of satisfaction and the thinner the body shape, chest, thigh, waist, finger, arms, the greater the satisfactions.

This study examined health-functional foods intake pattern of consumers and their recognition of it to prepare a guide for the foods. The data were collected from the adults living in Busan and Gyeongnam through a self-administered questionnaire from September sixth to September thirteenth, 2005. The results of this study were as follows: Most respondents have taken one health-functional food, mainly on purpose to maintain and improve overall health condition. The average of monthly cost to purchase the foods was 79,933 Korean won, and drugstores were the main purchasing place. The value perception about health-functional foods was at the middle, and the recognition level of Health Functional Foods Act established in 2002 was very low. The most important source of information regarding health-functional foods was family, relatives and friends, and two-fifths respondents had difficulties in obtaining information. These results imply that consumers should consult with experts before they take health-functional foods and that public information regarding Health Functional Foods Act should be given to consumers.

The purpose of this study is to classify breast types and to inquire about characteristics depending on breast types of women subjects in their twenties. We researched size items affecting breast volume and regression equations for the prediction of breast volume, and thereby, we will be able to provide some basic data, useful to the development of the brassiere depending on breast types. As a result of categorizing the types of three breast types, "type 1" was characterized by big and greatest protrusion of the breast with large breast volume and a large bust, while "type 2" was characterized by flat breasts with the least breast volume and least bust, and "type 3" was characterized by breast location apart from the center front line. Breast volume is significant in establishment of the brassiere cup depending on breast type. Five items such as, the circumference of the breast, the length of the upper breast, the depth of the breast point, the length of the shoulder point-breast point, and the length of the inferior breast were extracted through regression equations for breast volume.
