Purpose: It is important to acquire accurate data because the SPECT scan affected by various physical factors. The aim of this study was to compare the uniformity when both centers were matched or mismatched differed from position of heart in COR. Materials and methods: The images were acquired with cylindrical uniform phantom (6.7 cm diameter, 9 cm length) and heart insert phantom using Cardio MD SPECT system (Philips, USA). The phantoms were positioned on COR as well as four different points which were 10 cm above, below, left and right side from the COR. The counts from the both edge of cylindrical uniform phantom and those from the both wall of heart insert phantom were compared by using vertical and horizontal line profile. In addition, the qualitative evaluation was performed with heart insert phantom images and volunteer test. Results: In heart insert phantom study, the differences of counts between COR and 10 cm above, below, left and right point of COR were 1.1, 4.1, 4.9, 2.2 and 0.9% using T-A curve for horizontal view. In case of vertical view of COR 3.9, 21.9, 3.5, 23.9, 14.0% were shown. In cylindrical phantom study, the differences of counts between COR and 10 cm above, below, left and right point of COR were 4.3, 0.3, 3.3, 2.6 and 0.7% using T-A curve for horizontal view. In case of vertical view of COR 2.7, 3.0, 1.0, 0.3, 3.4% were shown. For qualitative evaluation, the images at COR were the most uniform for both of heart insert phantom and volunteer test, whereas other four positions showed somewhat distorted images. Conclusion: It showed the most uniform images when COR is matched with the heart. Therefore, we can expect that distortion which increased or decreased of myocardial perfusion will be prevented by matching the heart and COR when positioning. Furthermore, the accuracy of diagnosis will be improved as well.

The main nutritional problem of sorghum$\times$sudangrass hybrid silage is low quality and dry matter (DM) contents. This experiment was conducted to evaluate whether field pre-wilting treatment of sorghum$\times$sudangrass hybrid silage increases DM content and forage quality of the silage. The experiment was a randomized complete block design with three replications. The treatments were consisted of five different wilting days: 0 day (direct cut silage), 0.5 day, 1 day, 2 days and 3 days. Sorghum$\times$sudangrass hybrid silage with pre-wilting showed low 4.00 pH values, however direct cut silage (control) showed a 4.30 value because of its high moisture content. The DM content of sorghum$\times$sudangrass hybrid silage with pre-wilting was high above 25.1% after 1 days, however that of direct cut silage had 17.6%. And the effluent of wilted silage was decreased with prolonged wilting period, but that of direct cut silage produced effluent of 183 mL/kg. Crude protein and ether extract with wilted silage were decreased, however crude ash was increased with prolonged wilting period. Silage with pre-wilting had higher acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents than control silages, while its non-fiber carbohydrate (NFC) showed the opposite results. Lactic acid and total organic acid were increased with prolonged wilting period. For the palatability of dairy goat, silage with 2 days wilting was highest among silages. The experiment results indicate that wilted sorghum$\times$sudangrass hybrid silage could be recommended as effective method for reducing effluent, increasing pH and forage quality more than direct cut silage. Optimum pre-wilting day of sorghum$\times$sudangrass hybrid silage may be 1 days.

Objectives : In Pharmaceutical Affairs Act, herbal medicinal preparations are defined as medicines made by Korean medicine principles. But in Act, Korean medicine principles are vague. Thus, there is a request to explain what the Korean medicine principles are. The aim of this study is to suggest implications of Korean medicine principles in definition of herbal medicinal preparations. Methods : With regard for definition of Korean medicine principles, we referred to the domestic and foreign regulations and literature about the history of herbal medicinal preparations. As a result, the meaning of Korean medicine principles was historically examined from various angles. Results : Through this study, we studied the Korean medicine principles from the past medical history. Due to the broad definition of Korean medicinal principles, we tried to extract general ideas of medicine principles first. We also found that we had scientific formulations based on korean medicine principles which could be used in modern society. In the end, we found that numerous medicine principles which include ‘Four qi and five flavors theory’, ‘Processing of medicinals’, ‘Yin and yang theory’, ‘Five phases theory’, ‘Meridian entry of viscera and bowels theory’, ‘Herb Couplet Interaction theory’, ‘Sovereign, minister, assistant and courier theory’, etc. Conclusions : Innumerable principles used from the past existed. These principles were broad and could be used as modern scientific principles. Based on these facts, we illustrated details of Korean medicine principles, hope this principles be widely shared and Korean herbal medicinal preparations be further developed.

As Korea confronts one of the fastest aging societies in the world, it is urgently necessary to develop proper housings for the rapidly increasing elderly population. For this reason the purpose of this study is to find out the perceptions and needs of the apartment-living elderly people in order to plan apartments as good residential spaces where the elderly can live autonomously despite their physical aging. This study surveyed the healthy elderly people living in apartments in their 60s. The surveyed elderlies were asked to evaluate the importance after presenting them the items selected that belong to the items of lifetime home conception in the existing design guidelines for the elderly. The results of this study revealed that because the surveyed elderlies were healthy currently they did not think about the issue of their physical aging situation in future and they showed differences in their perceptions in case they hope to live continuously at their existing apartments and in case they hope to move to other residences for their aged years. This study will suggest the direction of planning for the unit spaces of apartments for the aged people in future.

This paper seeks to find out a relevant measure for harmonizing nationalism and universalism among Korea, China and Japan in Northeast Asia. The three countries in the region have for a long time been involved in history distortions and territorial disputes. These history distortions and territorial disputes have so far constrained rather facilitated coexistence and cooperation among three countries. In recent years, however, the author can find increasing foreign trade and investment, cultural and educational exchange, and NGOs networks among Korea, China and Japan. It is argued in the paper that cultural community rather than economic one would be more effective in furthering mutual understanding among three countries. In particular, ‘Korea-China-Japan Meeting for Historical and Cultural Understanding’(tentatively named) and ‘Korea-China-Japan Forum for Civil Society’ (tentatively named) are suggested to be established to consolidate social and cultural exchange and networks at both government and civil society level.

한국사회가 경험한 급속한 산업화의 이면에는 다양한 위험요소들이 자리잡고 있다. 본 연구는 제주도를 제외한 전국에서 표집한 일반국민 800명에 대한 경험적 조사자료를 토대로 하여 신체적ㆍ심리적 안전의 실태와 구조 그리고 안전이 삶의 질에 미치는 영항을 탐구하고 있다. 연구 결과는 삶의 질과 안전 모두 다차원의 복합적 구성을 갖는 현상임을 보여준다. 첫째, 삶의 질은 최소한 4가지의 요인으로 분해가 가능하며, 안전은 삶의 질의 주요 구성요소임을 알 수 있다. 둘째, 인간사회는 모험과 안전의 균형점을 상정하고 있으며, 그 균형은 문화나 사회체계, 그리고 하위집단별로 서로 다르게 형성된다. 셋째, 안전사고는 적어도 세 가지 집락으로 분류되며, 각 유형에 따라 사고원인, 사고의 빈도, 문제의 해결방안 등이 달라져야 함을 시사한다. Unexceedingly rapid industrialization in Korea produced not only the improvement of living standards but many side effects including safety problems. This study, utilizing the survey data on 800 respondents on the quality of life and psycho-physical safety, reveals several findings as follows: 1) safety is one of the key dimensions of quality of life, 2) people usually take an equilibrium between risk and safety, although the equilibrium point differs by culture, social system, and other demographic traits, 3) accidents can be classified into three different types, demanding a different approach on the cause, process, and solution in safety-related accidents. Major findings of this study implies that for the improvement of the quality of life, we should prescribe different policy measures according to the three different types of accidents.

One of the cardinal findings of the renal diseases is proteinuria, which appears in the early phase of kidney diseases and is very important in diagnosis, prognosis and decision making in the treatment process and results of the treatment. The study subjects were 126 patients who visited the nephrology department of Kangbuk Samsung Hospital. Serum was requested for urine protein electrophoresis. Total protein was measured with Bayer Advia 1650 (Biuret). Quantitation of each fraction was done by multiplying the percentage of each fraction by the total protein. Serum creatinine and BUN were also measured with Bayer Advia 1650 (Jaffe and Urease). Serum protein EP was done with REP(rapid electrophoresis) using Helena Kit reagents (REP Ultra SPE Kit, Ponceau S stain, Acetic acid, Methanol, EP Control). Concentrated urine was used for urine protein EP. The SPSS package was used for statistics analysis. Percentage and quantitation of the level of albumin in renal diseases were significantly lower than those in healthy controls. Total protein was correlated with albumin. In terms of proportion, α1-globulin, α2-globulin, β-globulin, and γ-globulin fractions were increased in the disease group. But, in the quantified level, α2-globulin was increased and β -globulin and γ-globulin were decreased. ESRD patients showed an increased secretion of high molecular proteins in urine protein EP. A decreased level in serum total protein correlated with the decreased level of serum albumin and the total amount of urine total protein. This study revealed the variety in the level of serum and urine proteins and their subgroups by EP.

The purpose of this study is to identify the structural relationships between factors that affect students’ creativity and integrity. From this study, we tried to draw implications for developing a teaching program and implementation strategy that can effectively improve creativity and integrity. A survey was distributed to 301 university students in the Seoul metropolitan area to conduct this study. Based on the results, metacognition, mastery-approach goal, and communication skills were shown to have a direct effect on the creativity. While mastery-approach goal, and communication skills also showed a direct effect on the integrity, metacognition did not. Autonomous educational climate showed a direct effect on metacognition, mastery-approach goal and communication skills, as well as an indirect effect on the creativity and integrity by mediating metacognition, mastery-approach goal and communication skills. The results of this study emphasize the importance of promoting metacognition, mastery-approach goal, communication skills, and autonomous educational climate within curriculum in order to improve the creativity and integrity of university students.

The objective of this study is to clarify that ‘I/Ga’, which cannot be regarded as case marker, can be considered as an auxiliary particle in terms of ‘contrastive focus markers’. For this purpose, I analyzed ‘I/Ga’ using information sturcure, particularly ‘focus’. I first identified characteristics of case marker ‘I/Ga’ as a focus marker. As a result, i t was examined that the case marker displays new informationas as semantic focus marker. However, not all ‘I/Ga’ in actual use was related to new information. Through this perspective, it was confirmed that ‘I/Ga’ in this case performed the function of the contrastive focus marker. In conclusion, through this analysis, it was confirmed that ‘I/Ga’ can be recognized as an auxiliary particle and handled within the same category as other auxiliary particle. This is because an auxiliary particle can generally function as a contrastive focus marker. This study is significant in that it is a complementary study of ‘I/Ga’ as a focus marker.
