In this paper, we investigates the basis of the theological aesthetics and the Bible as the standard of human value standards on the basis of this theological aesthetics. In another approach, unique designs of plants and animals were described in terms of aesthetics. These descriptions were then employed to design and create things, recognised for their beauty as well as practicable applications. From this point of view, we can deduce the relevance of God, the created world, and theological aesthetics. We review the implications of human engineering and the art of convergence and engineering theology. We discussed why the need for a tool of theological aesthetics in convergence engineering is important. We will need more discussion in terms of technological progress in which theological aesthetics is embodied in order to develop more healthy, moral and ethical convergent engineering skills in our society and to provide a better and healthier life for mankind.

Paul Rudolph's early work in Florida after World War II is a significant example of the regional transformation of typical Modern Architecture through the spatial composition based on the diversity and use of local material and construction methods. Paul Rudolph's concept of a Florida House design is the expression of regional material, construction, and structural system through the spatial extension & connection based on periodical, regional characteristics. The characteristics of the Florida works is the spatial extension & connection design based on the wood structural framework through the various design factors, such as a screen roof, open roof, and internal patio as the spatial extension and link method. Paul Rudolf designed the house using local materials, such as cypress wood and lime block produced near the Florida Area and provided details & technology considering the Florida climate and construction environment. Through studies of Paul Rudolph's Florida works, the Florida Houses can be a prototype of localization, and can be presented as the spatial & technical transformation of design by the historical, cultural, regional background.

We examined the effect of 12 main monoterpenes in Pinus plants on growth inhibition of Escherichia coli and Aspergillus nidulans. We tested four concentrations of each compound by comparing the clear zone with controls. (R)-(-)carvone, (S)(+)carvone, (1R)(-)fenchone, (-)menthone, α-pinene, (1S) (-)verbenone and (+)β - pinene had a inhibition effect on E. coli. (R)-(-)carvone, (S)(+)carvone, (+) β-pinene, geranyl-acetate, α-pinene, and (1S)(-)verbenone had inhibitory effects on the growth of A. nidulans. Geranyl-acetate inhibit growth of A. nidulans, however not to E. coli. And (1R)(-)fenchone and (-)menthone inhibit growth of E. coli, but not to A. nidulans. Myrcene, sabinene, bornyl acetate, and limonene had no inhibitory effects on E. coli and A. nidulans, eventhough at the highest concentration. All these results suggested that some selected monoterpenes had antifungal activities depend on the species of microorganism.

The protein in the extracts from the skins of pineapple and kiwi and the optimal conditions to hydrolyze blood, egg and gluten meals with them were investigated. Protein analysis by SDS-polyacylamide gel electrophoresis showed one protein band with 22 kd molecular weight in the pineapple skin extract, and Hve protein bands with 27 kd, 22.5 kd, 22 kd, 19 kd, and 14.4 kd molecular weight in the kiwi skin extract. The 22 kd protein in the pineapple skin extract is assumed to be bromelain, and the 27 kd protein in the kiwi skin extract is assumed to be actinidin, both are pretense. The optimal conditions for hydrolysis of blood, egg, and gluten meals we: 6-24 hours in time, $60^{\circ}C$ in temperature, and pH 4-pH 7.

Media convergence is prevalent all over the world, and is expected to change our lives dramatically in near future. Chaos theory is a new emerging theoretical approach to various social phenomena including organization management, economic system, stock market fluctuation, and so on. This thesis is intended to explain media convergence phenomena centered on internet media using basic concepts of chaos theory such as self-organization, co-evolution, and feedback loop. The implications of this tentative study are that we can apply chaos theory to media convergence as other social or natural phenomena, and that maintaining chaos state of media system is useful for accelerating creativities, and that developing media system as an organic system to cooperate with other relevant systems is helpful for promoting life qualities, and that establishing moral order or root value is desirable for implementing communicatopia.

This paper is to investigate the mechanical characteristics of light-weighted soils (LWS) consisting of expanded polystyrene(EPS), dredged clays and cement by using both uniaxial and triaxial compression tests. The mechanical characteristics of the compressive strength of LWS are analysed with varying initial water contents of dredged clays, EPS ratio, cement ratio, and curing stress. In the triaxial compression state, it is found that the compressive strength of LWS containing EPS is independent on the effective confined stress. As the EPS ratio decreases($A_E$<2%) and cement ratio increases($A_c$>2%), the behavior characteristics of triaxial compressive strength-strain relationship is similar to that of cemented soil which decreases rapidly in compressive strength after ultimate compressive strength. For the applications of LWS to ground improvements which require the compressive strength of up to 200kPa, the optimized EPS ratio and initial water content of dredged clay are estimated to be 3~4% and 165~175%, respectively. Also, the ultimate compressive strength under both triaxial test and uniaxial compression states are almost constant for a cement ratio of up to 2% and then critical cement ratio of this LWS shall be 2%.

This study is to examine effects of motorized flexion-distraction treatment on the pain, lumbosacral angle, lumbar lordosis angle, and lumbar 5 (L5) intervertebral disc angle in patients with chronic low back pain. We selected 30 cases of chronic low back pain, which were evenly divided into two groups: experimental group and control group. We applied the same hot pack, interferential current therapy, and ultrasound therapy to both groups. The experimental group had additional treatment of motrized flexion-distraction therapy and control group had additional of stretching exercise. For each subject, the pain, lumbosacral angle, lumbar lordosis angle, and lumbar 5 (L5) intervertebral disc angle were measured before and after treatment, While experimental groups showed significant improvements after treatment, more significant effects were found in the experimental group.

본 연구의 목적은 한국청소년들의 건강행동실태를 파악하기 위한 것이다. 본 연구의 의의는 미국에서 행해지고 있는 청소년의 건강유지 및 증진과 아울러 성인병이나 조기사망에 대한 역학적인 접근방식을 한국청소년을 대상으로 하여 응용하는 데 있다. 이 연구에 사용된 연구도구는 미국의 Centers for Disease Control에서 청소년의 건강행동을 역학적으로 연구하기 위해 개발한 Youth Risk Behavior Survey를 한국 사회환경의 요구도에 맞게 수정한 것이다. 본 연구는 한국인 청소년들의 건강행동을 조사하기 위한 타당성있는 연구도구를 개발하기 위해 4개의 단계로 구성되어 있다. 두번의 focus group discussion과 pilot test, 그리고 실제조사로 이루어져 있다. 서울지역의 중.고등학생을 대표할 표본추출은 cluster sampling을 사용하였다. Cluster는 본 연구에서 구분한 서울의 지리적인 구역들, 즉 북부, 남부, 그리고 산업지역을 포함했고, 남자학교, 여자학교, 남녀공학학교를 포함했다. 총38개 중.고교 학생 4,747명이 조사되었다. 약 52.4%의 응답자가 심각하게 자살을 생각해본 적이 있다고 답했다. 그리고 23.6%가 설문조사전 30일 중에 담배를 피운 적이 있다고 응답했으며 49.7%는 설문조사전 30일중에 술을 마신 적이 있다고 답했다. 약 29%가 설문조사전 30일 중에 싸움에 가담한 적이 있다고 응답했다. 본 연구에서 조사된 건강관련행동 (건강위험행동 포함)들은 성, 연령, 성적, 사회경제적 위치, 학교 종류, 그리고 서울의 지리적인 구역에 따라 다양하게 나타났다. 남학생이 여학생보다 더 간강위험행동을 나타내었다. 건강위험행동은 나이가 증가함에 따라 증가했다. 사회경제적 위치가 낮다고 응답한 학생들과 학급에서 성적이 하위라고 응답한 학생들의 경우 건강위험행동은 더 많이 나타났다.
