본 연구는 스마트폰 중독청소년 80명을 대상으로 스마트폰 의존도에 따라 세군 (일반사용자군, 잠재적위험군, 고위험군)으로 분류하여 생활습관, 식행동, 모발 무기질 영양상태에 차이가 있는지 분석하였고 결과는 다음과 같다. 1. 본 연구대상자는 스마트폰 의존도가 높을수록 평균 주중 수면시간이 유의하게 적었고 첫 흡연연령은 늦었다. 전체 대상자의 우울감 존재율은 32.5%, 음주율 66.2%, 흡연율 55.0%로 매우 높고, 규칙적인 운동시 행률은 42.5%로 나타났다. 2. 식행동 항목에서는 스마트폰 의존도에 따라 군간 유의한 차이는 없었지만 잠재적위험군에서 식사속도가 빠르고 배부르게 먹는다는 비율이 높았으며 하루 간식을 2회 이상 섭취한다는 비율도 상대적으로 높았다. 그러나 스마트폰을 이용하면서 식사하는 경우 식사속도와 식사량에 큰 영향을 미치지는 않는 것으로 나타났다. 3. 개인의 식행동에 영향을 미치는 요인은 부모 (45.0%)와 모바일 (30.0%)의 비율이 우위를 차지하였다. 전반적으로 개선이 필요하다고 판단한 식습관은 불균형된 식사 (35.1%), 빠른 식사속도 (17.5%), 과식 (16.3%)이었으나 잠재적위험군은 불균형된 식사 (38.5%), 과식 (30.8%), 빠른 식사속도 (11.5%)로 세 군간 유의한 차이를 보였다. 4. 영양 및 건강정보 습득처는 핸드폰이 전체 37.5%를 차지하여 가장 높았고 전체 대상자의 32.5%만이 영양교육 및 상담을 받아본 경험이 있으며 교육요구도는 38.8%가 필요하다고 응답하였다. 5. 모발 무기질 총 17종을 분석한 결과 전체 대상자들은 정상범위보다 셀레늄의 농도는 낮고, 납의 농도는 높은 것으로 나타났다. 인과 황은 모두 정상범위에 있었지만 잠재적위험군에서 농도가 유의하게 높았고, 알루미늄의 경우는 고위험군이 정상범위보다 높고, 세 군중 가장 유의하게 높았다. 6. 세 군간 유의한 차이를 보인 인, 황, 알루미늄을 여러 변수별로 비교한 결과 인은 스트레스가 적은 군 (OR 1.18), 황은 여성 (OR 1.14), 고등학생 (OR 1.19), 수면시간 6.5시간 미만 (OR 1.88), 스트레스가 많은 군(OR 1.34), 우울감이 있는 군 (OR 1.20)에서 유의하게 높게 나타났다. 알루미늄은 여성 (OR 2.25)과 흡연군 (OR 1.32)에서 농도가 유의하게 높은 것으로 분석되었다. 이상의 결과를 종합하여, 스마트폰 의존도가 높은 청소년의 경우 수면, 음주, 흡연 등 건강에 유해한 생활습관과 높은 결식률, 불균형된 식사, 과식, 빠른 식사속도와 같은 식행동의 개선이 필요한 것으로 관찰되었다. 또한 과도한 인터넷 사용에 따라, 성장기 청소년에 요구되는 일부 무기질의 부족과 과잉에 대한 문제점도 있는 것을 알 수 있었다. 본 연구는 스마트폰 의존도 문제를 지닌 청소년을 대상으로 실시한 연구로 비의존 대조군이 존재하지 않아 청소년의 스마트폰 의존과 생활습관 및 식행동, 모발 무기질 영양상태와의 관련성을 직접적으로 설명하는 데는 제한점이 있다. 그러나 과의존 청소년의 경우 전반적인 생활습관과 식습관에 문제점이 많고, 의존 정도에 따라 식습관이나 모발 무기질 영양상태에 차이를 보인 연구 결과를 통하여 청소년 스마트폰 의존정도와 식습관, 무기질 영양과의 관련성이 있음이 제시되었다. 본 연구를 통해 미디어중독 청소년의 영양관리에 관한 기초자료를 마련할 수 있었고 나아가 청소년의 건강증진과 건전한 정보문화 정착을 기대하는 바이다.

This study examined the effect of beauty involvement on self-satisfaction by conspicuous consumption tendency groups. A questionnaire method was used for this study. The subjects of this research were females in their 20s~50s. We distributed 580 questionnaires ets; constantly, 554 sets were used in the final analysis. Data were analyzed by factor analysis, ANOVA, cluster analysis, Cronbach's alpha coefficient and multiple regression analysis. Beauty consumption behavior factors were classified with hair styling, skin management, make-up and body shaping. Self-satisfaction factors were classified with living, appearance, economic and interpersonal relation. This study classified 4 conspicuous consumption groups (active, passive, syntonic and individuality & frugal group). The active conspicuous consumption group was unsatisfied with most of the self-satisfaction factors. The passive conspicuous consumption group was more interested in skin management factors than other factors. The syntonic conspicuous consumption group was interested in make-up, body shaping and skin management in order to provide a positive impression to other people. The individuality & frugal group was most interested in body shaping that could be achieved at low cost through exercise and diet.

The purpose of this study is to classify the stress into groups and analyze their differences in self-consciousness, and appearance management behavior. Questionnaires were administered to 377 middle and high school girls living in Deagu metropolitan City. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncant-test, and t-test are all used for data analysis. Our findings show that stress developed due to several reasons: the categories are as follows into grades-related low stress, exam-related high stress, and society-related high stress. For the purposes of our study, we labeled self-consciousness as a combination of being socially and privately self-consciousness and showing signs of social anxiety. Appearance management behavior deals with esthetic plastic surgery, clothing harmony, weight management, hair management, health care, skin care, and meal management. Stress shows a significant correlation with the sub-variable self-consciousness and appearance management behavior. The groups show a significant difference in the self-consciousness, and appearance management behavior. There is also a significant difference among stress, self-consciousness and appearance management behavior by grade. The students in seemed to recognize that their appearance can be improved by dressing up and managing their outwardly appearance. Teachers should educate students to have the variety of views on the meaning of beauty. In addition, schools need to develop programs to educate student about appearances, as the student's interests differ due to the stress type of the adolescent.

This paper focuses on the analysis of effects on fisheries sector following Korea-Japan Free Trade Agreement and the results are found as follows. In terms of national competitiveness, the RCA(Revealed comparative advantage) index shows that Korea is higher than Japan in most species items. And the calculation of TSI(Trade Specialization Index) finds that Korea is export specialized while Japan import specialized, showing that Korean fisheries sector is internationally more competitive than Japan. The tariffs on the marine products should be completely scrapped between Korea and Japan, export of marine products to Japan increases a mere 2%, while import from Japan 13.5%. In terms of value, annual export to Japan stands at 20,135thousand USD, while import from Japan at 12,137thousands USD, resulting in trade balance improvement of 8,000thousand USD in total. The tariff measures above is expected to have a positive effect on the related industry of marine products such as Oyster, Conger eel, Ark shells and Laver, but those involved in fisheries of Alaska pollack, Hair tail, Sea-bream(live fish), Red horsehead(frozen), Saury are expected to be negatively affected. Given the results of analysis above, the effects of FTA on the fisheries would be advantageous to Korea as a whole, but at the same time, the advantage and disadvantage sustained differs by fishery type and marine products. To that effect, negotiation strategies and countermeasures should be made, taking the results into account.

현재 세계 48개국의 의료기관에서 임상을 위해 널리 사용 중인 모발분석(TMA)은 중요 미네랄 비율을 분석하여 체내에 과잉, 결핍 및 불균형 상태를 평가하고 인체에 미치는 영향을 예측하여 건강유지 방향을 제시하는 임상 영양학 및 독성학 검사방법을 말한다. 그러나 국내 모발분석방법에는 몇 가지 문제점이 있다. 즉, 모발분석결과를 처리하고 해석할 수 있는 한국형 의료정보 데이터베이스가 없으므로 미국에 의뢰하고 있는데, 외화낭비는 물론 보내오는 모발분석 검사결과지가 영문이고 철저한 보안 위주파일이므로 국내의료 기관에서의 활용도가 매우 낮다. 또한 모발분석 결과가 서구식 데이터베이스로부터 분석된 것이므로 검사결과의 신뢰성 문제도 발생한다. 따라서 본 논문에서는 이러한 문제점을 해결하기 위해 국내 최초로 TMA 기반 한국형 의료정보시스템을 구축하였다. 이 시스템은 복잡한 모발분석 자료의 분류를 다단계 통계분석 방법에 의한 결정트리 분류기를 통해 수행하고, 다중 퍼지 규칙방식의 데이터베이스를 구축하여 지능형 퍼지추론 방법에 의해 모발분석 자료를 분석한다. 본 시스템의 성능을 실제 작업 환경에서 측정한 결과, 시스템을 사용하는 경우가 사용하지 않았을 경우보다 업무능률과 사용자 만족도가 각각 86%, 92% 증가하였다.
