최근 다변량 공정관리는 다양한 응용 분야에서 중요해지고 있는 추세이다. 예를 들어, 제조 산업 분야에서는 다변량 품질특성치를 동시에 모니터링할 필요가 있다. 그러나, 다변량 관리도는 이상신호가 발생한 경우 그 원인이 되는 개별적인 변수를 식별하기가 어렵기 때문에, 실제로는 기대만큼 유용하게 쓰이고 있지 않은 형편이다. 이에 본 논문에서는 새로운 관측치에 대한 개별적인 신뢰구간을 사용하여 이상신호의 원인을 탐지하는 세 가지 방법을 소개하고, 시뮬레이션 연구를 통해 이상신호의 원인이 되는 개별적인 변수를 식별하고 해석하는 데 있어 주의할 점이 무엇인지 살펴보기로 한다.

This study concerns with the reasons of the revision of the classification scheme and the kinds and methods of the reclassification. The reclassification IS to be implemented in case that classification numbers are wrongly given, or the scheme is revised, or it is wanted that presently using scheme should be changed to a different one. In the case of a revised edition, it is desired that reclassification is made based on the new edition because of the modernization of a data organization. However, in case of that it is not possible for the situations in the library such as the number of collections, staffs, facilities, budget, etc., the old edition can be based and the new one can be referred to. In this case, however, classification numbers may be dualized on one subject, and therefore, library must prepare the reference cards and the marks of the shelves for the different class numbers. Also, because much budget is required when the scheme is changed to another one due to its unsatisfactory usage, it should be carefully considered whether to change or not. The required time in reclassification for the relocated classification number of the revised edition is 18 minutes 54 seconds per volume, and its cost requires W 1,224.

Purpose: We analyzed the characteristics and differences in patients' medical benefits and health insurance based on disease severity classification. Methods: We examined 29,139 patients who visited the emergency medical center of K Hospital from January 1,2016 to December 31, 2016. Survey items included the Korean Triage and Acuity Scale (KTAS) classification of emergency and non-emergency situations ratio and type of insurance. Results: According to KTAS classification, 76.2% of patients exhibited an emergency condition and 23.8% exhibited a non-emergency condition. Emergency patients exhibited more trauma than non-emergency patients. According to the type of insurance coverage, the duration of stay in the emergency room was longer for patients with medical care than for patients with health insurance. Additionally, 119 ambulances use was significantly higher among patients with medical care. Conclusion: Policy discussions should address alternative ways to replace the 119 ambulances used by patients in this study. Additionally, health care administrators should identify alternative care agencies as potential alternatives to emergency room visits.

In recent years, the growing needs and the interest of the welfare for the disabled people has ignited the educational facilities for the disabled in Korea. This special schools are to be provide the disabled people with proper facilities to provide opportunities to participate in social life and to maximize the educational efficiency. However many special schools are not properly designed to educate the disabled because their design guidelines including legal planning standards. It is also true that these standards are not specifically categorized and specialized according to the kinds of disability. This study, therefore aims to suggest measures of the special school design guidelines especially for the mentally disabled people. The study first looks after the characteristics of the mental disability and the current situations of special schools in Gwangju. It, then examines the behavilr of the mentally disabled students in some of special schools in Gwnagju through observation and interview. The interview has done with the staff in the facilities regarding the usage patterns and behavioral characteristics of the mentally disabled students especially in convenience facilities in schools.

The purpose of this study is to suggest the design guide-lines for the community center through the analysis of users' satisfaction on the community facilities and programs. This study was approached by using theoretical investigation, a field survey and a questionnaire survey. The field survey was analyzed the current situations by conducting a housing managers' interview and viewing a blueprint of the community center. The questionnaire survey was tested by examining five different apartment complexes of over 500 households in Gwang-ju, which were all built between 2005 and 2007, 268 users were interviewed for the questionnaire survey. After all the questionnaires were collected, the data was coded and analyzed using the SPSS 12.0 program. Statistics used from data analysis were frequencies, means, standard deviations, one-way ANOVA, t-test, and correlation analysis. To conclusion, the satisfaction and usage of community facilities and programs shows higher for the indoor exercise/sports; such as, yoga, golf, and health programs than others. There is no strong correlation between the location and layout of community facility in apartment complex. However, this study could be a reference data when planning a new community center where plans to have community facilities and programs to satisfy its future users.

Semantic interpretation of the relationship between noun compound (NC) elements has been a challenging issue due to the lack of contextual information, the unbounded number of combinations, and the absence of a universally accepted system for the categorization. The current models require a huge corpus of data to extract contextual information, which limits their usage in many situations. In this paper, a new semantic relations interpreter for NCs based on novel lightweight binary features is proposed. Some of the binary features used are novel. In addition, the interpreter uses a new feature selection method. By developing these new features and techniques, the proposed method removes the need for any huge corpuses. Implementing this method using a modular and plugin-based framework, and by training it using the largest and the most current fine-grained data set, shows that the accuracy is better than that of previously reported upon methods that utilize large corpuses. This improvement in accuracy and the provision of superior efficiency is achieved not only by improving the old features with such techniques as semantic scattering and sense collocation, but also by using various novel features and classifier max entropy. That the accuracy of the max entropy classifier is higher compared to that of other classifiers, such as a support vector machine, a Na$\ddot{i}$ve Bayes, and a decision tree, is also shown.

Background : Mahuang (Ephedra sinica) has been used widely to treat respiratory disease in traditional medicine for over thousands years. Mahuang preparations contain approximately $0.75{\sim}1%$ ephedrine alkaloids. Recently in North America, the Eephedra alkaloids has aroused a controversy due to its adverse effects in those using whole extracts as "dietary supplements" for weight loss or athletic performance enhancement. Objective : To discuss the need for clinical practice guidelines on the use of Mahuang. Results and Conclusion : It is widely assumed that Mahuang is one of the useful medicines and is safe for human body. Most of scientific literatures support that the safety of Mahuang prescription in common dosage. However, it has been claimed that there were some warnings and apprehensions about the harmfulness of Mahuang as dietary supplements. This article does not negate the fact that it is necessary to pay more attention for use of Mahuang in clinical situations. We assert that the establishment of clinical practice guideline on the use of Mahuang, which is based on scientific materials and consensus, is required in traditional medicine.

Stress induces change to the body functions and causes chronic problems such as worsening a disease. Thus, humans want to evade anxiety and would try any means to reduce stressful situations. Generally, a person would handle their stress by either regulating their emotions or merely coping with the situation, for which the former is most widely used. Our research aims to effectively reduce stress by using the emotional response structure developed by Plutichik and the vitalization method. We extracted the relevant components of the stress-reduction method that would be applicable in any space using digital technologies such as sensors, IoT, and augmented reality. An architect or designer may incorporate these structural components into any structure to effectively reduce people's stress. The research aims to provide a new perspective of architectural space and to show applications of the stress-reducing architectural spaces, which should also fulfill the people's needs. Further research is needed to develop an automatic system to utilize spatial components more effectively.

Nowadays, various researches about eco-friendly vehicles such as hybrid electric vehicle, fuel cell vehicle and electric vehicle have been actively carried out. Since most of these green cars have electric motors, the regenerative energy technology can be used to improve the fuel economy and the energy efficiency of vehicles. The regenerative brake is an energy recovery mechanism which slows a vehicle by converting its kinetic energy into electric energy, which can be either used immediately or stored until needed. This technology plays a significant role in achieving the high energy usage. However, there are some technical problems for controlling the regenerative braking and the electro-hydraulic brake during switching at transient region. In this paper, the performance simulator for fuel-cell vehicle is developed and transient response characteristics of the regenerative braking system are analyzed in the various driving situations. And the hardware-in-the-loop simulation of electro-hydraulic brake is performed to validate the transient characteristics of the regenerative braking system for fuel-cell electric vehicle.
