인삼의 생산과정에서 부산물로 얻어지는 인삼엽을 건강 기능성 식품의 소재로 활용 가능성을 모색하기 위하여 인삼엽차를 건조법(DRT), 숙성법(AGT), 열처리법(HPT)등 3가지 방법으로 제조하고 화학적 조성의 변화를 조사하였다. 인삼엽차의 제조방법에 따른 일반성분 함량은 거의 유사하였으나 조지방, 환원당 함량은 HPT에서 감소되는 경향을 나타내었다. 유리당 함량은 DRT가 6.07%로 가장 많았으며 sucrose, fructose, glucose순이었다. 유리아미노산의 조성은 serine 이 309.6∼336.6 mg%로 가장 높았으며 valine, leucine, isoleucine, aspartic acid 순으로 그 함량이 높았고 DRT에 비하여 ACT, HPT에서 감소되는 추세를 나타내었다. 무기질 함량은 Ca 가 2,115 mg%로 가장 많았고 K, Mg, P, Na, Mn, Fe, Zn, Cu 순으로 제조방법 사이에 차이는 나타나지 않았으나 찻물의 무기질 함량을 좌우하는 침출율은 HPT가 가장 우수하였다. 특히 Zn, Mn, Mg등은 면역체계를 유지하며 체내 유해 활성산소의 제거에 관여하는 무기질로서 이들 함량이 높다는 점은 인삼엽차의 우수성의 하나로 평가된다. 인삼엽차의 총 비타민 C 함량은 HPT가 424.4 mg%로 가장 많았으며 침출율도 가장 높았다. 지방산 조성은 제조방법간 차이는 나타나지 않았으며 palmitic acid가 가장 높았고 linoleic acid, linolenic acid, oleic acid, stearic acid 순이었다. 한편 인삼엽차의 색도는 DRT에 비해 AGT, HPT 에서 L값이 감소하고 a값은 증가하여 갈색 물질의 증가를 나타내었다. 이상의 결과를 종합해볼 때 인삼엽차의 제조방법은 열처리법(HPT)에서 가장 우수한 품질을 나타낸 것으로 생각한다.

This paper is the first of several companion papers which compare the methods of Air-fuel ratio determination. There are many methods which calculate Air-Fuel ratio from exhaust emission. Most of them are based on the simple chemical equations, which use balance of atom, and the error of the calculation is negligible as far as the instrumentation accuracy is guaranteed. They assume homogeneous mixture and complete combustion to the extent of oxygen availability. Because of these simple assumptions, they cannot offer the information about the fuel distribution state and the malfunction of instrument. For these limitations, Eltinge offered new one based on stricter mathematical model. This result coincides with the others very well and gives more information about the mixture state and instrumentation. Consequently this might be a general solution for Air-fuel ratio determination and exhaust composition. The objects of the calculation, however, were not commercial fuels except gasoline and the compensation method of unburned hydrocarbon was not appropriate to recent analyzer. Moreover he did not consider the fuel which contains oxygen, such as methanol, ethanol and blend of gasoline-alcohol. In this paper, Eltinge chart is expanded to the arbitrary fuel composition as the reference exhaust compositions for the purpose of further discussions about Air-fuel ratio determination methods and the charts fur gasoline, diesel, methanol, M85, liquefied petroleum gas(LPG), natural gas(NG), propane, butane are illustrated.

In this paper, we introduce a recursively-defined natural join operation as well as well-known object composition operations (union, intersection) for composing CAD database objects. Then, we will discuss how to realize these operations by the message passing computing mechanism. Next, we will discuss what kind of behaviours (methods) are preserved under our natural join operations. Finally, we investigate mathematical properties about the relationships among several object composition operations (natural join, union and intersection).

We have studies fatty acid composition of water extracts of parts of omija (Schizandra chinensis Baillon) and antioxidant activities of fractionated omija parts (fruits, endocarps, seeds) were determined by DPPH methods and by in vitro hepatic microsomal lipid peroxidation system. Fatty acid composition was not different by parts of omija and major fatty acids are linoleic, oleic, and palimitic acids, among fatty acids is water extracts of parts of omija, linoleic acid was highest in content. Methanol and buthanol fractions of seeds and ethyl acetate fraction of endocarps showed stronger antioxidant activities by DPPH methods. Methanol and buthanol fractions of seeds also showed on inhibitory effect on in vitro liver microsomal lipid peroxidation.

The load forecasting has been essential in planning and operation of power systems. The load composition rata is also needed to analyze power-systems - load flow calculation and system stability. This paper proposes the monthly peak load forecasting methods for load groups in residential class using load composition rate and electric consumption characteristics. The proposed methods were applied to a real-scale power system and the effectiveness was turned out.

Purpose: This study aims to suggest the spatial composition and area of the intensive care units through analysis of current situation for the standards establishment of the intensive care units in public district hospitals in the future. Methods: Three Methods have been used in this paper. 1) Literature reviews about composition, location, foreign standards on intensive care units. 2) Comparative analysis on the architectural drawing for the space program and the area. 3) Field survey in order to confirm differences between architectural drawing and current situation. Results: 1) The intensive care units is required to be linked by the operating department, the emergency department and the sterile supply department upon considerations of accessibility of emergency patients and the infection control. 2) The intensive care unit consists of five areas such as the patient area, the medical staff area, the material and equipment area, the patient family area, and the public area. 3) The location of spaces in the intensive care unit is classified by three methods such as connection by view, circulation and connection to corridor. The [table 20] summarizes the type of space and the average size of the space in intensive care unit. Implications: This study is a basic research for guideline of intensive care units, and need to be followed by further study using various perspectives and methods in the future.

Music is composed according to time flow. In case of music therapy, it is the most important thing and this properties must be emphasized in operation, also act as one of the most important elements that increase the effect of medical treatment. Especially in the case of Oriental Medical music therapy, we must consider the change of time and space, so determine the direction and methods of treatment. In order to compose the music therapy process according to time flow[plot composition], first we have to analyze the musical and literary works that have step-by-step composition. Next we must consider how Gi(氣) changes occur in the base of principle of Eumyang(陰陽) and Ohaeng(五行). When the rule of composition as time flow is grafted onto Oriental Medical music therapy, native characteristics of music would have significance.

The service composition based on Service-Oriented Architecture(SOA) can make us view various machines or its functionalities in the Web or Internet-of-Things environment as 'service', and efficiently create new value-added services that users want by compositing different services if there is no service to satisfy the client. The service composition problem with respect to behavioral descriptions deals with the automatic synthesis of a coordinator service that controls a set of services to reach a goal state. Despite its importance, however, solving the service composition problem with only partial observations remains to be doubly exponential in the number of variables in service descriptions, rendering any attempts to compute an exact solution for modest size impractical. Toward this challenge, in this paper, we propose novel approximation-based approaches using abstraction methods. We empirically validate that our proposals can solve realistic problems efficiently.

PURPOSE: The purpose of this study was to investigate the differences and correlation between body composition, exercise performance, and behavior based on playing football in childhood. METHODS: 16 subjects who played football in childhood participated in the study. Body composition and exercise performance were measured, and problem behavior was assessed for each of them. All subjects were asked to play football 50 min/day, one day/week for 8-weeks. RESULTS: Muscle mass, muscular strength, balance, and cardiopulmonary endurance, anxiety depression, atrophy depression, attention problems, rule violations, DSM somatization problems, DSM rebellious behavior problems, and sociality significantly increased after 8-weeks. There was a negative (-) correlation between anxiety depression and atrophy depression, and DSM somatization problem and muscular strength, attention problem and balance, and rule violation and cardiopulmonary endurance, after playing football. CONCLUSION: These results confirmed that playing football in childhood had a positive effect on body composition, and that exercise performance and problem behavior were related.
