PURPOSES: According to accident statistics for road built in 2004, the ratio of accidents on frozen roads to normal roads is 0.9%, whereas the fatality ratio is 2.7%. The risk of accidents on frozen roads is very high. Measures taken every year to prevent traffic accidents of frozen roads in the winter season are still insufficient. Additionally, measures have been established mainly on rural roads. Therefore, for urban roads, analyses and measures to prevent accidents are lacking. In this study, data on accidents on frozen roads was used to search for the causes behind these accidents and measures to reduce accidents have been recommended. METHODS: In this study, collected data from the TAMS (Traffic Accident Management System), which were collected by the Seoul National Police Agency was used. The data were divided into vehicle, people, and condition of road. The analytical model used here was the Logistic Regression Model, which is frequently used for traffic safety and accident analysis. This study uses the odds ratio analysis to search for variables related to frozen road traffic accidents in each category. A total of 18 out of 47 variables were found to be the causes of accidents. RESULTS: From the results of the comparative analysis of 18 variables, the category of the condition of the road was found to be the most critical. Contrary to expectations, more accidents occurred in clear weather than in other conditions. Accidents on bridges occurred frequently, and its odds ratio was the highest compared with other road types. When BPT is operated, the probability of accidents on frozen roads is lower than in general conditions, and accidents occurred frequently on roads with less than four lanes. CONCLUSIONS : Based on the results of this study, suggestions for reducing the risk of future domestic road accidents in freezing conditions are indicated as follows. First, it is necessary to perform a technical review of the urban road traffic accidents caused by frozen roads. Second, it is necessary to establish criteria for the study of the road environment based on the major causes of road accidents on frozen roads. Third, improvements in urban road environmental factors should be made.

This study aimed to segment Chinese fisheries consumer market by means of cluster analysis based on Shanghai region consumers. The survey is conducted to 350 shanghai people on March 17－21 in 2014 and investigate demographic characteristics and consumer’s behaviors unique to each segmented market by preference, labelling, quality, price, safety. The result of cluster analysis identified four market segments such as Catering type market, Worth pursuing type market, Substance pursuing type market, Trend pursuing type market. Catering type market is a passive fisheries consumption market and is not high attractive for Korea fisheries export market. Value pursuing type market consider importance to labelling, origin, brand and require high-quality and differentiation strategies. This market’s main target species are high price fisheries such as tuna, salmon, crocker. Substance pursuing type market consider fisheries’s safety and quality and purchases more popular fisheries such as crocker, hairtail, promfret, mackerel, squid. Trend pursuing type market’s consumers prefer to purchase brands and trendy seafood rather than taste.

The objective of this study is to investigate consumer preferences, perception and consumption patterns for fish products. To investigate the difference in consumer responses according to the characteristics of the population parameters, data were collected from the survey of 404 Koreans and analyzed. The results are as follows: First, the differences of age; for the question of the reason why do you eat fish products, the younger generation (20〜30s)’s most answer was‘The Taste’while the older age groups(40〜50s and over 60s)’most respond was‘For Health’. Second, the differences of sex; women relatively considered‘The Quality’of fish products more important than men when selecting the products. Whereas, men thought‘The Taste’of fish products more important than women when they choose fish products. In addition, when the bad news or hygiene accidents about fish products are reported on media, women reacted more negatively for fish products purchase than men. Third, the differences of family members; the respondents who lived with 3 or more family members showed higher preference rates about purchasing trimmed fresh fish at the store than respondents who lived with 2 or less family members. On the other hand, single households relatively bought processed fish products and RTE(Ready To Eat) fish products more than other family member groups. In addition, single households preference rates about eating fish products as a main dish were very high compared to other groups.

PURPOSES: This study is to conduct the research on the design principle for the driver's safety and comfort in installing consecutive curves of superhighway. METHODS: Superhighway does not currently exist in domestic area. Thus, this study is conducted by collecting driving behavior usage of 30 people who are involved in the members of the virtual driving simulation. By identifying the distribution characteristics of each scenario in ANOVA & Tukey Test, the distribution are categorized into three groups. RESULTS : In the case of Group A in Section 3 (R2 entry part), lane departure exceeds the safety standard, which means to be risky condition. And then in the case of Group B and C, the lane departure values applying theoretical formula was evenly distributed compared to the proven values. CONCLUSIONS : Based on the result, the continuous curve design principles at superhighway should follow three standards as follow. First, an additional linear part needs to be inserted between two curves. Second, what if inserting the linear part is difficult, it would be better to insert a curve more than 2,000m. Third, R1/R2 ratio should not be over two. This design primarily aims to the safety of the operator. Such road alignment also meets the expectations of drivers, thus, it may help drivers to be compatible and amenable while driving continuous curve in superhighway.

This study aimed to redefine the concept of fishing village tourism. In addition, it aimed to carry out detailed analyses of the influences of authenticity and non-authenticity of fishing village experience on tourist’s satisfaction as well as the influences of tourist’s experience on their satisfaction. The study evaluated responses of people who visited research target fishing villages in the East sea area(Hwasung-si Baegmi-ri) which had been rated as successful case. The evaluation was performed to analyze how tourist satisfaction would be influenced by the authenticity of the fishing village experience program based on the authenticity theory(Wang, 1999) and the experience realms theory(Pine & Gilmore, 1999). This study tried to find out realistic factors of the experience realms theory through field investigation, conducting interviews, and holding discussions. From these, the cause-and-effect structure of authenticity, tourism experience and satisfaction could be identified. The results of hypothesis tests are as follows; With respect to the relationship between authenticity and satisfaction in hypothesis I, authenticity did not have a statistically significant effect on satisfaction, while non-authenticity had a significant influence. As a result, the research hypothesis I that authenticity influences satisfaction was partially supported. Regarding hypothesis Ⅱ of the link between authenticity and tourism experience, a significant effect of authenticity was found in education experience, entertainment experience for Baegmi-ri village. The effect of non-authenticity was significant on deviation experience. Consequently, hypothesis Ⅱ was also partly supported. The relationship between tourism experience and satisfaction in hypothesis Ⅲ was significant in education, entertainment, and deviation experiences which lends support to hypothesis Ⅲ to some extent.

2007년부터 2008년까지 동해안에 분포하는 8개 석호에 대한 어류군집에 대하여 조사한 결과는 다음과 같다. 조사기간 동안 확인된 어류는 총 34과 66종 126,224개체였으며 생체량은 2,024.8 kg이었다. 각 석호의 출현종과 개체수를 대상으로 군집분류를 실시한 결과 보존이 양호한 그룹, 담수의 영향을 받는 그룹, 그리고 해수의 영향을 받는 그룹 등 3그룹으로 나누어졌다. 한편 선행연구자료를 각 연대별로 나누고 본 조사에서 출현한 담수어, 기수어, 그리고 해수어의 종구성비를 비교한 결과, 1990년대 이후부터 담수어가 감소하고 해수어가 증가하는 등 일부 석호에서 어류군집의 변화가 역동적으로 변화하고 있었다. 이러한 변화는 기수호에서 담수호로 변화해가는 자연적인 습성천이에 대한 역천이로 볼 수 있으며 향후 석호의 보존 및 관리, 그리고 복원을 실시할 때에는 석호 본연의 생태적 특성과 습성천이 과정에 대하여 충분히 검토 및 고려되어야 할 것으로 사료된다.

어류개체군에 대한 탁수의 영향을 파악하고자, 2004년부터 2005년까지 탁수하천(대기, 자운천)과 비탁수하천(봉산천, 계방천)에 분포하는 금강모치 개체군의 체장-체중 관계와 비만도지수의 변화를 알아보았다. 탁수하천과 비탁수하천간의 금강모치 평균전장을 비교해본 결과, 유의한 차이가 없는 것으로 나타났다. 남한강에서 체장-체중 관계에 따른 회귀계수 b값은 봉산천에서 3.21, 그리고 대기천에서 3.07로 나타났다. 이에 반하여, 북한강에 위치한 탁수하천의 회귀계수 b값은 비탁수하천의 값보다 약간 높았다. 그 값은 계방천에서 3.20, 자운천에서 3.23으로 각각 나타났다. 우리의 연구 결과는 금강모치 개체군 단계에서 만성 탁수의 영향이 적음을 보여준다.

영랑호 어류군집의 시 공간적 분포를 알아보기 위하여 2005년 9월부터 2007년 4월까지 조사하였다. 채집된 어류는 총 16과 32종이었으며, 일차담수어는 11종(34.38%), 주연성담수어는 18종(56.25%), 해수어는 3종(9.38%)인 것으로 나타났다. 조사 지점 및 시기별 군집의 변화양상을 파악한 결과 갯터짐이 일어나면 생태적 특성에 따라 어종의 출현 비율이 변화하는 것으로 나타났다. 또한 영랑호의 어류상에 대한 과거 자료와 비교해 보았을 때 해수의 유입이 일어나면 주연성담수어와 해수어의 비율은 증가하고 일차담수어의 비율은 점차 감소하는 것으로 나타났다. 이와 같이 석호 내의 어류군집은 갯터짐에 따라 시 공간적으로 그 성격이 매우 달라는 것으로 나타났다.
