The author reviewed seventy papers on social psychology of clothing and fashion marketing fields, which were published in the Journal of the Korean Society of Clothing and Textiles between 1983 and 1996. The market variables and consumer behavior variables were focused on. This review showed that the market variables had been divided into three groups of variables: 1) product variables (product image and product classification): 2) brand variables (brand image and brand positioning): and 3) store variables (store image, store type, and distribution system) Consumer behavior variables have been studied on the basis of EBM Consumer Behavior Model: 1) purchasing motivation as need recognition: 2) information using as search information: 3) evaluation criteria and choice criteria as alternative evaluatioin : 4) clothing purchase, brand choice and store choice as purchase: 5) degree of wear, satisfaction and dissatisfaction as outcome: and 6) clothing discard. Variables that influence on consumer behavior, including situation variables, clothing attitude variables, personal . social variables were added to develop a variable model of clothing consumer behavior using the EBM Consumer Behavior Model.

In this study simply supported nonlinear Euler-Bernoulli beams resting on linear elastic foundation and subjected to the axial loads is investigated. A new kind of analytical technique for a non-linear problem called He's Energy Balance Method (EBM) is used to obtain the analytical solution for non-linear vibration behavior of the problem. Analytical expressions for geometrically non-linear vibration of Euler-Bernoulli beams resting on linear elastic foundation and subjected to the axial loads are provided. The effect of vibration amplitude on the non-linear frequency and buckling load is discussed. The variation of different parameter to the nonlinear frequency is considered completely in this study. The nonlinear vibration equation is analyzed numerically using Runge-Kutta $4^{th}$ technique. Comparison of Energy Balance Method (EBM) with Runge-Kutta $4^{th}$ leads to highly accurate solutions.

Objectives : To develop and validate High-performance liquid chromatography-photodiode array methods for simultaneous determination of two constituents in Oryeong-san(ORS). Methods : Reverse-phase chromatography using a Gemini C18 column operating at $40^{\circ}C$, and photodiode array(PDA) detection at 280 nm, were used for quantification of the two marker components of ORS. The mobile phase using a gradient flow consisted of two solvent systems. Solvent A was $H_2O$ and solvent B was acetonitrile. Results : Calibration curves were acquired with correlation coefficient ($r^2$)>0.9999, and the relative standard deviation(RSD) values(%) for intra- and inter-day precision were not exceed 1.0%. The recovery rate of each compound was in the range of 93.01-104.16%, with an RSD less than 2.0%. The contents of two compounds in ORS were 1.10-3.72 mg/g. Conclusions : The established HPLC method will be helpful to improve quality control of ORS.

지하수위의 상승에 따른 간극수압의 증가는 사면의 불안정을 야기할 수 있다. 그러나 모델링 오차, 계측오차, 모델변수의 불확실성 등과 같은 오차로 인하여 사면에서의 지하수위 변동을 예측하는 것은 매우 어렵다. 이러한 불확실성을 극복하고 지하수위 변동을 평가하기 위한 최적의 모델변수를 구하기 위하여 역해석 기법이 사용되고 있다. 본 논문에서는 사면에서의 지하수위 변동을 예측하기 위하여 포화대에서의 지하수 흐름과 불포화대에서의 지하수 흐름을 동시에 고려할 수 있는 수치해석 모델과 변수예측기법을 적용하였다. 따라서, 본 논문에서는 포화투수계수($K_{s}$ ), 포화흡인력($\psi$$_{e}$) 및 불포화 투수계수의 함수에 사용되는 경험적인 상수(b)를 주요 매개변수로 선정하여 역해석을 실시하였다. 그리고, 역해석 기법 가운데 Maximum Likelihood(MK), Maximum-A-Posterior(MAP) 및 Extended Bayesian Method(EBM)에 대하여 비교연구를 실시하였다. 위의 세가지 방법 가운데 EBM은 가상의 변수(Hyperparameter) $\beta$를 도입함으로써 현장계측치와 사전정보를 가장 잘 조화시키는 방법으로 다른 ML, MAP 보다 탁월한 방법인 것을 알 수 있었다.

The purpose of the study is to produce the surface ground temperature diagnostically using surface EBM with the use of GRID model in Geographic Information Systems (GIS). Certain characteristics have been analyzed for local slope effect, coastal effect and influence of high orographic aspect on the surface ground temperature. We present discussions on the meteorological responsibility for their temperature. The derived surface ground temperatures can be provided for comparison with those from satellite-based observ ation.

The use of complementary and alternative medicine (CAM) is currently widespread and appears to be growing. As an increasing proportion of the population turns to CAM therapies, whether singly or in combination with allopathic medicine, the need for quality research in this area is reinforced. Much of this research consists of clinical studies aim ed primarily at clinicians, yet challenges arising from poor methodological quality will occur w hen interpreting study findings and their implications. For clinicians to be effective consumers of the scientific literature, familiarization with the principles of evidence based medicine (EBM) is essential. The goal of this review is to introduce clinicians to the concept of critical appraisal of clinical studies and foster critical thinking when reading research articles in order to best evaluate and incorporate study findings into their daily practice.

Recently, metal additive manufacturing (AM) is being investigated as a new manufacturing technology. In metal AM, powder bed fusion (PBF) is a promising technology that can be used to manufacture small and complex metallic components by selectively fusing each powder layer using an energy source such as laser or an electron beam. PBF includes selective laser melting (SLM) and electron beam melting (EBM). SLM uses high power-density laser to melt and fuse metal powders. EBM is similar to SLM but melts metals using an electron beam. When these processes are applied, the mechanical properties and microstructures change due to the many parameters involved. Therefore, this study is conducted to investigate the effects of the parameters on the mechanical properties and microstructures such that the processes can be performed more economically and efficiently.

To support Integrated Services in the Internet, the Internet Engineering Task Force(IETF) has developed new mechanisms. These new mechanisms include Resource Reservation Protocol(RSVP) and Integrated Services model. RSVP and Integrated Services are independent of the underlying link layer technologies and it is necessary to define the mapping of RSVP and Integrated Services specifications onto specific link layer technologies. IETF proposed a Subnet Bandwidth Manager(SBM) providing a method for mapping RSVP onto IEEE802 style networks. However, the SBM has several constraints and problems. For solving these constraints and problems, we design and implement a new Ethernet Bandwidth Manager(EBM). This paper discusses (1) new bandwidth management mechanism independent of RSVP, (2) simulation of Ethernet bandwidth to analyze the characteristics of Ethernet and accomplish Ethernet bandwidth management, (3) design and implemetation of EBM that allows Controlled-Load Service, and (4) results of our experiments on EBM.

The lung is the most common site for the metastasis of extrapulmonary malignant tumors. However, endobronchial metastases (EBM) from extrapulmonary malignant tumors are rare. The most common extrathoracic malignancies associated with EBM are the breast, renal and colorectal carcinomas. Lung metastasis from prostate cancer is often encountered but EBM is rare. We report a 74-year old man with endobronchial metastases from prostatic carcinoma presented with cough. The diagnosis of prostatic cancer and the endobronchial metastasis were confirmed by immunohistological staining with the prostate specific antigen. Hormonal therapy (lutenizing hormone releasing hormone agonist) was applied to this patient.

Objective: To check the status of traditional Korean medical doctors' medical services amid the continual increase in the number of traditional Korean medicine clinics. Methods: A survey of traditional Korean medicine clinics based on questionnaire sheets mailed to 4,200 out of 10,895 clinics, of which 465, or 11.0%, responded, in the June 1, 2008 to December 9, 2008 period. Results: 1. 65.6% of the traditional Korean responding clinics are doing business in a rented space; 92.1%of them are one-person institutions; 24.4% of them, i.e., the largest group of those surveyed, operate in a space sized 41 (123 $m^2$)~50 pyeong (150$m^2$). The number of sick beds installed in their facilities comes to 7.9 on average. 2. Concerning support staff, 190 of them (or 40.9%), i.e., the largest group of those surveyed, employ two people in this capacity. They generally comprise assistant nurses (48.7%) and others (47.6%). 3. The size of the space used by the clinics is showing a tendency to increase. The number of sick beds and support staff, including assistant nurses, reached a peak in 2006, and has been on the decrease since then. 4. The average number of on-days comes to six days a week among 92.6% of those surveyed. Their average daily service hours come to 9 hours and 33 minutes (from 9:17 am to 6:50 pm). 5. Per-patient service time: 14 minutes on average; per-patient acupuncture time: 18.8 minutes; per-patient moxa cautery time: 10.1 minutes per-patient; boil-cupping time: 5.7 minutes; per-patient physical treatment: 28 minutes. Conclusion: Periodical studies should be carried out concerning desirable ways of developing traditional Korean medicine clinics with the focus on the facilities, doctors' service hours, and types of service.
