  • Tomb No. 1 (Donghachong) of the Buyeo Neungsan-ri Tomb complex (listed as UNESCO World Heritage Site), is a royal tomb of the Baekje Sabi Period. One wooden coffin unearthed there is an important relic of the funerary culture of the Baekje. This study examines the production techniques of gilt-bronze objects attached to the wooden coffin excavated from Donghachong. The base metal of the gilt-bronze object is pure copper, with single α phase crystals in a heterogeneous form containing annealing twins; Au and Hg are detected in the gilt layer. We suggest that the surface of the forging copperplate is gilded using a mercury amalgam technique; it is thought that the annealing twins of the base material formed during the heat treatment process for the sheet metal. The gilt layer is three to five times thicker for the gilt-bronze objects found near the foot of the coffin than those near the head. We estimate the plating process is carried out at least three times because three layers are identified on the plate near the head. Therefore, it is likely that the materials and methods used to construct the gilt-bronze objects found in different parts of the coffin are the same, but the number of platings is different. This research confirms the metal crafting techniques used in Baekje by the examination of production techniques of these gilt-bronze objects. Further, our paper presents an important example of restoration and reconstruction for a museum exhibition, through effective use of scientific analysis and investigation.

  • The purpose of this study is to establish a model of cultural sustainability in the traditional village. Cultural sustainability is being advanced by promoting the viability of traditional arts and the unique regional features of traditional culture, such as folklore, traditional landscapes, buildings and other environments of outstanding historical value. These cultural resources were also created or occurred at specific geographic locations at certain points in time by different individuals. The content of this study was to develop a model using indicators for cultural sustainability, and to apply and evaluate the model. In older to evaluate the model, Sonwon-ri village in Yongchon, located in Kyungsangbuk-do, was selected as the case study area. The major findings are as follows: 1) Sonwon-ri village has maintained the vernacular landscape except at the entrance of village. Also, the village people have pride and have adapted to the natural environment. 2) Sonwon-ri village has a self-sustaining system and circular network within its environmental capacity. Sonwon-ri village has many historical sites and buildings such as important folk resources, cultural assets, traditional houses and pavilions. 3) The people how the theory of fens-shui which interprets the location of village in relationship to a crane mountain with the village situated as a crane head. These symbolic and cultural elements have an important role in establishing the boundary of the village. From the research it can be seen that Sonwon-ri village kept many cultural sustainability indicators in terms of active factors, physical factors and psychological factors. By analysing the participation of different scientific disciplines and identifying disciplinary categories, this study provides a basis for understanding how cultural sustainability is subjected to research in the field of landscape planning and design.

  • "P2 sir-관련 도움파지 비효율성"이라는 용어는 P2 sir 변이체가 그들의 위성 박테리오파지인 P4에 대해 도움파지 역할을 충분히 못하는 것을 가리키는 용어이다. 이 연구의 목적은 이러한 P2 sir-관련 도움파지 비효율성을 극복하는 요인들을 조사하는 것이다. 우선 P2의 cos 영역을 함유하는 P4 sid71 cosP2가 P2 sir3의 도움파지 비효율성을 극복하는지를 조사하였다. 그 결과 P4 sid71 cosP2는 P2 sir3의 도움파지 비효율성을 극복하지 못하였다. P2의 cos 영역 대신에 $P2_{sir}$-sized head에 packaging되는 DNA 크기가 도움파지 비효율성을 극복하는 중요한 요인으로 나타났다. 이 연구에서는, DNA 조작을 통해 packaging 되는 DNA 크기가 P4 ost1과 P4 ost2 사이가 되는 세 종류의 P4 유도체를 조성하였다. 그 중 하나인 P4 sid71 delRI::apr의 CsCl 균등밀도차실험을 거쳐 packaging되는 DNA의 크기를 확인하였다. P4 유도체들의 후손방출량 실험에 따르면 그들은 모두 P2sir3-관련 도움파지 비효율성을 극복하였다. $P2_{sir3}$-sized head에 잘 packaging되는 P4 유도체의 크기는 28-29 kb로 나타났다.

  • This thesis studied the costumes of Gwan-Rye(관예). the lowest ranking officials of Yi-Dynasty. It researched the written materials and compared it with relics of Gwan-Rye costumes. The gists of the result are; 1) The Koryo tradition of Gwan-Rye costumes continued until the early days of Yi-Dynasty. 2) The Gwan-Rye costumes can be classified into two styles. One is Sa-Ryung(사영) style, which consisted of Dan-Ryung(단령) robe and Jo-Geon(조시) as head gear. Na-Jang(라장) style. the another, consisted of Dan-Ryung. Ban-Bi-Ui(반비의) and Jo-Geon. 3) These styles changed around the days of Yeon-San(연산), the 10th King of the Dynasty. The Na-Jang of later days wore Cheop-Ri(첩리) robe instead of Dan-Ryung. And the Sa-Ryung costume was devided into three different styles. They are (1) Gat(립)- Cheop-Ri (2) Bung-Geo-Ji(단립)-Chang-Ui(창의) (3) Gat- Kwoe-Ja(쾌자) styles.

  • The purpose of this study was to investigate possible age differences in the attenuation of acceleration in the upper body (from pelvis through shoulder to head) during fast walking. Thirty young and 29 elderly subjects participated in this study. Wireless acceleration sensors were attached on head, shoulder, and pelvis. Subjects performed two trials of fast walking on a treadmill, where the fast speed was defined as 1.5 times of the comfortable speed. Root-mean-squared (RMS) accelerations of each axis were compared with age group and sensor position as independent factors. In the AP direction, the pelvis acceleration was greater in the young and the shoulder-to-head attenuation was also greater in the young (p<0.001), so that the head acceleration was comparable between age groups (p=0.581). In the ML direction, the pelvis acceleration was greater in the young and also the pelvis-to-shoulder attenuation was greater in the young (p<0.001), so that the head acceleration was greater in the elderly group (p<0.001). Insufficient attenuation ML acceleration in the elderly resulting in the greater acceleration in the head may deteriorate the balance control which utilize feedback signals from the sensory organs in head, e.g., vestibular and visual systems.

  • Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.

  • A 71-year-old woman was assigned to our department for Tc-99m myocardial perfusion SPECT(MPS) and coronary CT angiography. She admitted for substernal pain, via the ER, 2 days ago. The heart was scanned after intravenous injection of 925 MBq of $^{99m}Tc$-sestamibi adenosine-induced stress SPECT using dual head gamma camera (Hawkeye, GE healthcare. USA). The MPS shows decreased tracer uptake in the apical & mid area of anterior & lateral wall and mid & basal inferior wall. Coronary CT angiograph was obtained using Discovery VCT (GE healthcare). 3D angiography portrayed significant stenosis of ramus intermedius(RI) and posterolateral branch of right coronary artery(PLB) with fibrocalcified plaque. Two images were fused using Cardiac IQ fusion softwear package (Advantage workstation 4.4, GE healthcare) The fusion images explain the perfusion defect of anterior, lateral and inferior wall is due to stenosis of the RI and PLB. And 3 days later, coronary angiography was done and revealed the marked stenosis of RI and PLB. Then balloon angioplasty and stent was instituted in RI. Cardiac SPECT/CT fusion imaging provides additional information about hemodynamic relevance and facilitates lesion interpretation by allowing exact allocation of perfusion defects to its subtending coronary artery.
