VTS의 관제 범위에서 발생한 교통관련사고 분석은 VTS의 개선방향 검토에 중요한 기초 자료를 제공할 것으로 기대되나 현재까지의 연구는 미흡한 실정이다. 분석은 최근 6년(1999-2004년)간의 해양안전심판재결서와 VTS 센터별 자료 및 Port-Mis자료를 이용하여 이루어졌다. 연구결과, 1) 교통관련사고의 통제 및 VTS의 개선 방향을 검토할 필요성을 확인하였다. 2) 교통관련사고의 경우 관제여부에 따라 사고원인과 시정상태, 충돌사고의 상대선 인지거리 및 인지지체원인에 차이가 발생함을 통계적으로 확인하였다. 3) VTS의 지원은 충분한 시간 전에 적극적이고 지속적으로 이루어져야 하며 04-08시 시간대에 강화되어야 함을 확인하였다. 4) 사고예측모형을 통해 관제선박의 교통관련사고는 일평균 교통량에 큰 영향을 받고 있으므로 VTS 운영자가 사고의 위험성이 높은 선박을 우선적으로 식별하여 관련 정보를 신속하고 적극적으로 제공할 수 있도록 지원하는 시스템을 구축하여야 한다.

The purpose of this study was to investigate the perception and eating behaviors of middle school students in Kwangju area about food and nutrition section of Home Economics course. The subjects were 480 middle school students. The major results were as follows： On the perception f food and nutrition section, the 1st graders learned ‘how to settle the problems related to food and nutrition and food choices’. The 2nd graders learned ‘the knowledge and principle of food and nutrition for improving dietary life’. The 3rd graders learned ‘actual dietary life functions like arranging menu and preparing meals’. Consequently, there was a significant difference in each grade and all boy and girl students have the highest response to the item ‘they learn how to settle the nutrition problem and foods choices’. On the interests in food and nutrition section, lower graders and girl students have higher interest than hgiher graders and boy students. The area which was considered as most interesting in food and nutrition sections was ‘cooking’ in all students. The perception of the concern on dietary life after learning food and nutrition section was higher in the 1st graders. On the perception of the area where was a great change in their own dietary life after learning food and nutrition section, the 1st graders responded there was a great change in ‘balanced dietary life’, the 2nd graders in ‘eating habit and nutrition of adolescence’and the 3rd graders in ‘cooking’. Especially, girl students showed more changes. On the perception of degree which food and nutrition section gives a help to actual life, students over 50% responded that it was helpful to their actual life. This showed that the lower the grades, the more help it gave to those students. On the perception of mother’s job, the students with working mother considered that they learned ‘actual dietary life functions like functions like arranging menu and preparing meals’from the food and nutrition section. In addition, they had high interests in the area of ‘cooking’. It was recognized that as the family size was greater, the food and nutrition section gave more helps to actual life. On eating behaviors of breakfast, the higher the grade, the more frequent they don’t have breakfast, boy students have more frequencies of having breakfast than girl students and the primary reason of not having breakfast is poor appetite. On whether going without a meal affects study or not, most of the 1st, 2nd and 3rd graders whether they are boys and girls or not responded it affected their study. On eating behaviors of lunch, most of boy and girl students in the 1st, 2nd 3rd grade have lunch box. On eating behaviors of supper, eating time is usually between 7：00 and 8：00 p.m and eating hour is mostly 10 or 15 minutes. On eating behaviors between meals, frequency of eating between meals is mostly once or twice a day and girl students have more frequencies of eating between meals, and the cause was hunger commonly in boy and girl students and ‘killing time’in girl students.

환경 소음의 무절제한 노출이 청력 손실로 이어질 수 있다는 보고는 익히 알려져 있지만, 지하철 실내 소음과 휴대용 음향기기 음량에 따른 이중 소음 노출에 대한 탑승객들의 청력 손실 여부는 많은 연구들에서 여전히 진행 중이다. 본 연구는 지하철 실내 소음 하에서 탑승객들이 이어폰을 이용하여 개인음향기기 사용 시 음향 반사 역치와 소음속 어음인지도가 어떻게 변화하는 지 확인하고자 하였다. 20대의 젊은 건청 성인 40명을 대상으로 실험 그룹과 대조그룹으로 각각 20명씩 구분하였다. 실험 전 모든 대상자에게 5개의 주파수에서 음향반사역치검사와 0, -5 dB SNR에서 문장검사를 실시하였다. 실험 그룹은 60분간 73.45 dBA의 실제 서울도심지하철의 평균 실내 소음 강도를 들으며 개인별 선호 음량으로 이어폰을 통해 좋아하는 음악을 들었고, 대조그룹은 동일강도의 지하철 소음에만 노출된 채 신문 혹은 잡지를 읽었다. 60분간의 지하철 소음 노출 후 음향반사역치검사와 소음 속 문장검사를 재실시하여 기준선과 비교하였다. 소음 노출 전 후 비교 시, 두 그룹 간 음향반사역치는 유의미한 차이가 없었다. 그러나 소음 속 문장 검사결과에서는 실험 그룹의 어음인지도가 소음 노출 후 유의하게 하락하였다. 본 결과를 근거로 지하철 탑승객이 일정기간 동안 지하철 실내 소음에 노출된 채 반복적으로 음악을 듣는 습관이 지속될 시 일시적인 어음인지력 저하의 위험이 예상 될 것이라고 생각한다.

This study integrated mother's control behavior of child's misbehavior within social domain analysis and the framework of attributional models of social cognition. The purpose of this study was to identify, compare and contrast maternal attributions and control responses according to child's age and domains of social behavior, and to investigate that mother's social cognition factors(authoritarian attitude and self competence perception) influence material inference and responses for their child's acts. Then this study was to find out whether mother's attribution would mediate their socialization techniques. For empirical research, 654 mothers with 5.6 year old and 8.9 year old children as subjects answered the structured questionnaire. The data were analyzed by frequencies, t-test, oneway ANOVA, and multiple regression. The major findings were as follows: First, according to child's two domains of misbehavior, there were differences in mothers'attribution and control behavior. Also mothers regarded older child's behavior as more dispositional cause and as more deserving of punishment than younger child's. Second, mother's authoritarian altitude of parenting, self-competence perception, and educational level were significantly related to mother's judgment. Third, the more authoritarian attitude mothers had, the more dispositional factor of children they attributed. And the lower self-competence mothers perceived. the more internal factor of child they attributed. Finally, maternal attributions and control responses are interrelated. When they attributed their children's misdeeds to internal dispositions, they respond with more stronger control behavior. The results suggested maternal social cognition mediate socialization behavior.
