태풍이 내습하면 선박은 이를 피해 적절한 묘박지를 선정하여 묘박하게 된다. 묘박 중인 선박은 일단 태풍의 영향권에 들어가면 바람, 파도 및 해${cdot}$조류에 의해 발생되는 외력와 이에 대응하여 묘와 묘쇄에 의한 파주력 및 기관 추진력에 의한 선박의 대응력이 서로 균형을 이룸으로써 주묘되지 않고 안전하게 견딜 수 있다. 본 연구에서는 묘박 중인 선박이 주묘되지 않고 견딜 수 있는 외력의 한계를 이론적으로 분석할 수 있는 방법을 제시하고, 이를 2003년 9월 태풍 매미가 내습했을 당시 진해만에 묘박했던 선박에 적용해봄으로써 그 타당성을 검토하였다.

Objectives: The aim of this study was to model the avoidable burden of the risk factors of road traffic crashes in Iran and to prioritize interventions to reduce that burden. Methods: The prevalence and the effect size of the risk factors were obtained from data documented by the traffic police of Iran in 2013. The effect size was estimated using an ordinal regression model. The potential impact fraction index was applied to calculate the avoidable burden in order to prioritize interventions. This index was calculated for theoretical, plausible, and feasible minimum risk level scenarios. The joint effects of the risk factors were then estimated for all the scenarios. Results: The highest avoidable burdens in the theoretical, plausible, and feasible minimum risk level scenarios for the non-use of child restraints on urban roads were 52.25, 28.63, and 46.67, respectively. In contrast, the value of this index for speeding was 76.24, 37.00, and 62.23, respectively, for rural roads. Conclusions: On the basis of the different scenarios considered in this research, we suggest focusing on future interventions to decrease the prevalence of speeding, the non-use of child restraints, the use of cell phones while driving, and helmet disuse, and the laws related to these items should be considered seriously.

The necessity for the investigation of death occurred in military services has no differences to the death of civilians. But the death of military service members under the Universal Conscription System in Korea has special considerations because of hard accessibility by the bereaved family and closed environment of the army. The analysis of the death occurred during military service was carried out and the advanced death investigation system to prevent the death was proposed to prevent the declination of fighting spirit and efficiency and also to restore the solid support by the people. The deaths in the period 1995~2006 were 330 persons in 1995, 359 persons in 1996 and were decreased to 135 persons in 2006. The death caused by safety accidents including vehicle accident, drowning, fall were 56% and by military crimes including suicide, arms, homicide were 44%. The numbers of suicides were 108 persons in 1995 and were decreased to 79 persons in 2006. The numbers of suicides were decreased constantly, but the ratio of suicide to death were increased, so the suicide prevention is more important. The autopsy ratio was increased to 51.5% in 2005 and was much higher compared to the ratio for civilians. The main reasons of complaints by the bereaved family were for regaining reputation, death in harness and reinvestigation of death. The proposals for the advanced death investigation system were as follows. The unnatural deaths including the obvious accidental deaths and homicides have to be defined by the rules. The human resources to perform the autopsy can be supported by the forensic pathologists from medical school. The special training and quality assurance programs are needed for the crime scene investigator. To regain the impaired reputation from the suicide and to support the bereaved family has to be discussed by the government.

Objective : The current study investigated the prevalence and clinical characteristics of sexual exhibitionism and frotteurism, which was conducted for the first time in Korea. Methods : Among 568 total subjects (mean age $19.28{\pm}5.0$ year), 109 were victims of sexual exhibitionism (19.2%, VSE) of which 57 were females (91.9 percent) ; and 57 were victims of sexual frotteurism (10.9%, VSF) of which 57 were females (91.9%). The participants completed the self-reported scale for epidemiological and clinical characteristics. Results : Incident frequencies of above two times of VSE and VSF were 49 (50.0%) and 20 (32.3%), respectively. Incident locations of VSE were school/office 37 (33.3%), street 28 (25.6%), and near home 20 (18.3%). Also, incident locations of VSE were inside of bus 12 (19.3%), subway 12 (19.3%), subway/bus station 8 (12.9%), near home 8 (12.9%), and school/office 7 (11.3%). Notifying rate of VSE and VSF to the police were 7.3% and 0%, respectively. Also, notifying rate of VSE and VSF to family or friends were 72.5% and 58.1%, respectively Conclusion : These results suggested that VSE and VSF had a common prevalence, which could be different from behavioral and emotional characteristics of a control group ; and the victims were shown to require an active intervention by supportive social system.

전 세계적으로 고학력화는 만연한 현상이며 점점 더 심해지고 있는 추세이다. 고학력의 효과성에 대한 많은 연구들이 발표되고 있지만, 주로 2000년대 이전의 연구가 많고 진행된 연구도 서구권 국가를 대상으로 진행되었다. 또한 제조업 및 일부 공공영역(예; 경찰)을 주된 표본으로 사용하였고, 다양한 조절변수를 다루지 못한 한계점이 있다. 이러한 상황에서 학력과 조직행동 연구의 중요 변수인 직무만족과의 관계 및 그 관계에서의 조절효과를 살펴보는 것은 의미가 있을 것으로 생각된다. 이에 본 연구에서는 조직 내 인력이 기업의 성과에 크게 영향을 미칠 수 있다고 생각되는 병원 근로자들을 대상으로 최종 학력이 직무 만족에 어떠한 영향을 미치는지 그리고 상황변수인 직급이 이들 간의 관계를 어떠한 방향으로 조절하는지에 대해 분석하였다. 연구문제를 검증하기 위해 경기북부의 1개 병원에서 근무하고 있는 377명의 간호사, 의료기사, 행정직의 자료를 실증분석 하였다. 회귀분석 결과 최종 학력은 직무만족과 정의 관계를 가지는 것으로 확인되었으며, 개인의 직급이 높아질수록 최종학력이 직무만족에 주는 긍정적 관계는 완화되는 것으로 나타났다.

Fishing vessels have been causing more than 70% of marine casualty in Korea. As a view of the occurring number of marine casualty, it is obvious for fishing vessel to account for the absolute high portion of that in comparison with the non-fishing vessels. That is a natural outcome because fishing vessels have occupied more than 90% of all registered Korean vessels. If we consider it not occurring number, but occurring ratio, we could find out that fishing vessels accounted for 5 times lower than non-fishing vessels in marine casualties. Nevertheless, fishing vessels have not immunity from responsibility for marine casualties at all, because the tendency of it in fishing vessel has been dominating the whole marine casualties in Korea. So for reduction of them, it is indispensable to decrease the casualties of fishing vessel. In this study, the authors tried to carry out many items of them to compare the occurring number with the occurring ratio, and dealt with the casualties of collision and machine damage in detail, because those have not only been occurring most frequently in casualties in Korea, but also led to the death and injury of lives. To reduce the collision and the machine damage, the operator have to keep the watch more strictly and check and keep the machine in good order. And it is necessary for the operator to take more education and training intended to decrease those systematically and continuously, especially for the crews of fishing vessels.

A retrospective study has been made of 170,026 cases of motor vehicle accidents which had been reported to the National Police Headquarters of Republic of Korea, 1983. Also a study has been made of 264 cases of road traffic casualties who were treated at the Eul-ji General Hospital from Jan. 1, 1983 to Dec. 31, 1983. This study was conducted to find out the nature and pattern of the traffic accidents from the clinical and epidemiological view points. In additions, the modes of injury from the road accidents were persued which might help to reduce the traffic accident rate. The results of the study were summarized as follows; 1. In this study, the highest incidence was in the age group between $21{\sim}30$ years (21.29%). And the age group of highest death rate was under 10 years (7.28%). 2. In the comparison of sexual differences, male was dominated in accidents number and death rate. (Casualty rate; 61.66%). 3. In the comparison of each hour differences, the accident was mostly occured during afternoon from 16:00 to 18:00(12.23%). 4. The most common day of week was Sunday (14.74%). 5. The most common season of year was Autumn (27.92%). 6. In the comparison of occupational differences, the high incidences were showed in labor men (31.06%) and business men (12.12%). 7. In the comparison of accidental vehicles, the most common vehicle were cars and the next were trucks and buses. 8. The most common mechanism of accidents was collision (57.41%). 9. In the comparison of clinical differences, orthopaedic and neurosurgical injuries were most common types of the hospitalized casualties. 10. In the comparison of anatomical fracture sites, the most common site was tibia (15.81%) and the next site was femur (12.56%).

The development of teaching models to strengthen practical education and actively participate in the classes of students is now required in recent education situations. This study examined the participation and satisfaction level of students' classes after applying a teaching model-integrated hospital and school laboratory (named L2L). A total of 33 students who took the subject of a clinical microbiology experiments were involved in this study. Each group representative participating in a pre-class field exercise in the hospital microbiology laboratory was asked to conduct the experiment. After applying the L2L teaching models, the academic self-efficacy ($2.87{\pm}0.58{\rightarrow}3.38{\pm}0.55$), class participation ($2.60{\pm}0.92{\rightarrow}3.62{\pm}0.78$), and class satisfaction ($2.48{\pm}1.01{\rightarrow}3.85{\pm}0.87$) increased significantly (P<0.05). This means that pre-class field exercises created interest in the student's class and boosted self-confidence, leading to increased participation and satisfaction for the class. In conclusion, the L2L teaching model is an effective teaching method to enhance the practical training for preliminary clinical laboratory technologists.
