선박의 충돌회피 방법을 제시하는 관점에 있어, 두 선박의 조우각도에 따른 속력이 충분히 고려되어야 할 것이다. 하지만 선박의 충돌회피를 위해 새롭게 연구된 근접상황 선박충돌회피지원 모델의 Safe-Guard Ring 설정은 본선과 상대선박의 속력비가 약 1.7 이하로 제한되어 있으므로 제한된 범위 이외의 경우에서 충돌 위험이 존재 할 수 있다. 따라서 본 연구에서는 두 선박이 조우하는 각도 및 속력을 고려한 Safe-Guard Ring 설정을 연구함으로써 안전한 충돌회피 조종을 위한 선박충돌회피모델을 제시하고자 한다.

본 연구는 항해사가 근접상황에서 심리적 충돌의 두려움으로 당황하여 규정된 충돌 회피조치를 수행하지 못하는 인적오류 상황을 연구하였다. 연구 목적은 선박 간 근접상황에서 항해사의 인적특성 요인인 승선경력, 면허등급, 연령요인이 충돌위험도에 미치는 영향을 규명하는 것이다. 본선과 상대선박 간 네 가지 대표적인 근접상황의 충돌침로에서 항해사가 지각한 충돌위험도 값을 측정, 정량화된 데이터를 얻기 위하여 시뮬레이터를 이용하여 충돌위험도 측정실험을 설계하고 두 척의 선박이 거리 2.5해리에서 충돌상황까지 상호 10노트의 속도로 접근할 때 본선의 30명의 항해사의 심장박동변이를 측정하여 항해사가 지각한 충돌위험도 측정데이터를 확보하였다. 측정값에 대한 다중회귀분석 결과 항해사의 승선경력과 면허등급 요인은 충돌위험도에 부(-)의 영향을 미쳤고, 연령은 영향을 미치지 않았다. t-검정 결과 승선경력≤4년인 항해사는 승선경력≥5년인 항해사 보다 충돌위험도 값이 유의미하게 높았고 면허등급 요인은 4 ~ 6급 그룹이 2 ~ 3급 그룹보다 충돌위험도 값이 유의미하게 높게 나타났다. 본 연구결과는 충돌위험경보시스템 개발에 적용될 수 있을 것이다.

The distribution of hepatic veins within the liver in 28 Korean native cattles were observed. Vinylite solution was injected into hepatic veins of seventeen specimens for cast preparation. The angiography was prepared in eleven specimens by injecting 30% barium sulfate solution into hepatic veins, and then radiographed on a X-ray apparatus (Shimadzu 800 MA 120 Kvp). 1. About two thirds or three quarters of the circumference of the Vena cava caudalis was embedded in the liver. The embedded portion was about 14~19cm in length. 2. The principal branches of the hepatic veins were Vena hepatica sinistra, Vena hepatica media, Vena hepatica dextra and Vena hepatica dorsolateralis; the three main hepatic veins were Vena hepatica sinistra, Vena hepatica media and Vena hepatica dextra. 3. The Vena hepatica sinistra joins the Vena cava caudal is near the esophageal impression of the liver. It gave off three or five branches to the left lobe. 4. The Vena hepatica media joined at the Vena cava caudalis close to the Vena hepatica sinistra. In all cases, Vena hepatica media opened near the diaphragmatic part of the liver than the Vena hepatica sinistra. It ran obliquely through the medial part of right lobe and quadrate lobe, giving off branches on each side. 5. The Vena hepatica dextra consisted of one(25 cases, 89.29%) or two separate veins(3 cases, 10.71%), joining to the Vena cava caudalis between the right and caudate lobes. 6. The flap of membranous tissue covered the dorsal half of the entrance of the Vena hepatica sinistra, media et dextra into the Vena cava caudalis. 7. The vestige of the ductus venosus persisted in the 12~18 months old cattles. 8. The anastomosis was observed in the intralobar and interlobar areas.

It is commonly known that upper class house in Chosun Dynasty has characteristics of connecting space in combination with 'Chae' and 'Madang'. But living territory of traditional residence is connected each other by means of the necessity of dwelling life. So, it can be a fragmentary understanding about traditional houses to consider it as connecting space only from the viewpoint of visual perception. Residential space in later Chosun Dynasty is affected by practical life-style rather than building principle of 'Confucianism' due to the erosion of the caste system and the spread of the modern residential culture. So, it is necessary to consider dwelling life at that time in order to understand spatial characteristics of the residences. Researcher made an assumption that these characteristics were observed in the emerging upper class houses which appear in the process of change of the caste system rather than the traditional upper class houses. The researcher investigated connecting space from 'Bakat-ma-dang' to An-ma-dang of the emerging upper class houses in Gyong-gi province. The goal of this study is to find the properties of connecting space related to dwelling life of the emerging upper class houses in Gyong-gi Province. With this study, the followings are the characteristics of connecting space in emerging upper class houses in later Chosun Dynasty. First, 'An-ma-dang(Courtyard)' comes into close contact with 'Bakat-chae(Outer quarters)' which accommodate the complex functions, 'An-ma-dang' plays an mediating role between 'An-chae' and 'Bakat-chae' Second, 'Bakat-chae' generally encases 'An-ma-dang' which is central territories of dwelling life, and the men's area of 'Bakat-chae' considerably has opening space towards the outside. Third, 'Anmadang' plays an mediating role of male's and female's living territory, and it plays an important role in connecting space where labor forces are concentrated.

Despite the fact that chogakpos are part of our wonderful Kyubang(the women's quarters in the Chosun Dynasty) culture with their own unique beauty and artistic values, there has been no scientific and objective proof of their aesthetic values. Once they are proved for their beauty through scientific analysis, they will be recognized worldwide along with our unique culture. The methodology included a review of related literature and theses along with magazines, periodicals, and Internet books. The analysis of lines parting, the dimensions of chogakpos were carried out over 108 pieces introduced in Old Pojagis by Heo Dong-hwa. As for line parting, the dimensions of chogakpos were measured to see if the golden and Geumgang ratio could be applied and to discover their unique partition ratio. As a result, there was the presence of the golden ratio applied to them with the golden curves from golden triangles and rectangles also found therein. The Yeoijumunbo confirmed that there was the golden ratio between the radius of a circle and a side of a regular decagon inscribed in the circle. The common line ratio among the squares, isosceles triangles, wanes, and overlapping rectangles was around 1:1.31, which means that there was a unique line ratio in the traditional chogakpos. Furthermore, the ratio of 1:1.31 was close to the Geumgang ratio commonly used in the traditional buildings of Korea.

This study aims to know word forms and usages according to personal relationships of 'Kureru Kudasaru' by analyzing dialogues of female speakers. Novels of the Meiji period when there were attempts of a language revolution were mainly used for this study as well as novels of the Edo Period and the Taisho Period. Firstly, the number of examples according to gender differences in the novels was as follows. In case of 'Kureru', female speakers showed a high usage rate in the novels of the Edo period. 'Kureru' was mostly connected with female languages such as 'Naharu', 'Namasu', 'Nansu'. These expressions were not used in the novels of the Meiji Period and the Taisho Period. Although 'Okureru' and 'Okurenasaru' were used in the novels of the Meiji Period, the number of examples of 'Kureru' by female speakers was decreased in the novels of the Meiji Period and the Taisho Period. 'Kudasaru' was predominantly used by female speakers. Especially, female speakers used clearly to show vertical relationships in the novels of the Edo Period and"Doseishoseikatagi"of Meiji 10s. After"Ukigumo", the usage rate of female speakers was decreased but the usage rate of male speakers was increased. Gender differences became gradually smaller. Female speakers in the novels were increased from geisha and relatives such as wife, sister, mother and children to young women, teacher and student. Aspects of benefactive verbs' usages could be summarized as follows. Female speakers at licensed quarters used clearer and more typical expressions according to vertical relationships and gender differences in the novels of The Edo Period than the novels of The Meiji Period and the Taisho Period. In the novels of the Meiji Period, female speakers in a sophisticated social group used benefactive verbs to show strong respect and concern for the other person. In the novels of the Taisho Period, female speakers used benefactive verbs to show respect and concern for the other person according to their areas of outside activities. In the novels of the Meiji Period, female speakers used 'Okureru' when the other person was younger than them and was socially and psychologically close to them. Also, 'O~Nasaru' which was one of respect expressions was used by female speakers. Female speakers used it to older people in the Edo period but they also used it to younger people in the Meiji Period. Examples were not shown in the novels of the Taisho Period. Usages of 'Kureru' 'Kudasaru' according to vertical relationships were as follows. If 'a giver' was an older person, 'Kureru' with respect expressions 'Nasaru' 'Nansu' 'Namasu' was used more than 'Kudasaru' in the novels of the Edo Period. However, many examples of 'Kudasaru' were shown on the novels of the Meiji Period and the Taisho period. In the novels of the Meiji Period, 'Okureru' and 'Okurenasaru' which were expressions included in 'Kureru' were shown. Female speakers used them to older people who were socially and psychologically close to them like family. There were not many examples of 'a giver' and 'a receiver' around the same age. However, 'Kureru' and 'Okureru' were used in a younger group and 'Kudasaru' was used in an older group in the novels of the Meiji Period. If 'a giver' was an younger person, 'Kureru' was mainly used in the novels of the Edo period and "Doseishoseikatagi"in Meiji 10s. However, 'Kudasaru' was used many times in the novels of the latter Meiji Period and the Taisho Period.

배표의(拜表儀)는 황제에게 보내는 외교문서인 표문(表文)에 치르던 의례로, 세종 대에 행하여진 배표의에 참여하는 사람들의 직책과 그에 따른 복식을 살펴보았다. 의례 주체자인 왕은 최고 법복인 면복을 착용하였고, 면복은 구류평천관에 구장복으로 구성된다. 왕세자와 종친, 문무백관은 조복인 양관과 적라의를 착용하였다. 왕세자의 조복은 세종 10년에 오량관에서 육량관으로 바뀌었고, 문종 즉위년에 왕세자의 면복을 받아서 단종 이후에는 팔류평천관과 칠장곤복을 착용하였다. 사행원인 사자와 종사관은 상복을 착용하였다. 사자가 착용한 상복은 사모에 흑단령, 서대, 협금화이고, 종사관이 착용한 상복은 사모에 흑단령, 흑각대, 흑피화이다. 왕의 측근에서 시종하는 별감은 공복과 상복을 착용하였다. 공복은 자건에 청단령과 흑피화, 상복은 주황초립과 직령에 조아, 흑피화로 구성되었다. 의장군은 황의장과 왕의 의장이 진열되었고, 산과 개, 수정장, 금월부를 들고 있는 자는 자건에 청의를, 전도황기는 피모자에 청의를 착용하였다. 선과 금은횡과·금은입과·금은장도는 피모자에 홍의를 착용하였다. 시위군은 갑옷과 투구에 검 또는 궁시를 갖추어 착용하였다. 공인 중 악사의 복식은 복두에 비공복, 금동혁대, 비백대대, 오피리로 구성되었고, 악생은 개책에 비수란삼, 협고, 말대, 말, 오피리로 구성되었다. 이상의 결과로 세종 대에 의례복식이 의제화되는 과정을 확인할 수 있었다. 배표의에 참여하는 왕 이하 왕세자, 문무백관, 사자, 별감, 시위군, 공인 모두 각 품계에 맞는 최고 등급의 예복을 착용하였다. 세종은 유교를 바탕으로 한 국가를 건설하고자 거듭된 논의를 거쳐 각 의례와 그에 따른 복식을 정비하였고, 배표의 복식도 직책별로 체계적으로 갖추어졌다. 세종 대에 정리된 의례복식은 예전에 규정화되어 조선 후기까지 이어질 수 있는 기틀이 되었다.
