The form and location of chin is very important factor which determine the facial impression. Genioplasty is getting popular in order to improve the facial impression as facial beauty is considered as improvable factor. Through the geniplasty, chin can be moved to wanted location 3 dimensionally Genioplasty is relative simple but precise diagnosis and accurate surgical technique is very important for accurate and satisfying results. The form and shape of chin itself can be analysized and also must be evalulated in relation to the nose and lip and face. Author introduces the analysis of the chin, various surgical techniques of genioplasty and presents some cases.

Logistics parks make profits using the efficiency of time and space. Such logistics parks play an important role in a corporation creating operating profits as well as acting as a method of alternative investment for individuals. Logistics parks no longer simply store materials, but have become a place that plays an important role in various areas of corporate and individual activities, and thus the analysis of the selection of the location of logistics parks and the related characteristics is extremely important. The estimation model is established by the weights for industry derived from AHP(Analytic Hierarchy Process).

We use three-dimensional magnetohydrodynamic (MHD) simulations of flux emergence from solar subsurface to corona. In our previous work, we reported the relation between magnetic-field configuration and the flux expansion factor. Following these results, we investigate where an upflow is generated in an active region and how its location is related to the flux expansion factor. We also derive physical quantities of a real active region from observation data provided by Nobeyama Radioheliograph (NoRH), X-Ray Telescope (XRT), and Extreme Ultraviolet Imaging Spectrometer (EIS) onboard Hinode. These physical quantities are plasma density, temperature and flow. By comparing the simulation result and observational one, we will discuss the properties of the location producing a solar wind.

The effect of column loss location on the structural response of steel moment resisting frames (MRF) is investigated in this study. A series of nonlinear static and dynamic analyses were performed to determine the resistance of a generic frame to an arbitrary column loss and detect the structural members that are susceptible to failure progression beyond that point. Both force-controlled and deformation-controlled actions based on UFC 4-023-03 and ASCE/SEI 41-06 were implemented to define the acceptance criteria for nine APM cases defined in this study. Results revealed that the structural resistance against an arbitrary column loss in the top story is at least 80% smaller than that of the bottom story. In addition, it was found that the dynamic increase factor (DIF) at the failure point is at most 1.13.

IoT is collection of different "things" which are associated with open web. As all the things are connected to the Internet, it offers convenience to end users for accessing the resources from "Any Where, Any Time" throughout the globe. At the same time, open nature of IoT provides a fertile ground to an intruder for launching different security related threats. If we can no apply proper security safeguards to the IoT System, then it will be not useful to society. Authentication, Encryption, Trust Management and Secure Routing are different domains to offer security in IoT system. Among them, Authentication is very much important security service as it validates device identity before granting access to system services/ resources. Existing IoT Authentication algorithms are fail to verify device identity in unambiguous way. They are vulnerable to different security threats such as Key Stolen threat, MITM threat and Location Spoofing threat. So, it is a demand of time to design an efficient and secure Multi-factor IoT algorithm which can offer better security and validate device identity in unambiguous way.

The solid waste incineration facilities which cause environmental pollution. And those are some kind of loathing facilities for residents who do not want it. This problem could be solved by location feasibility study. The purpose of location feasibility study was to determine one site out of three candidate sites. This study which was done by the law, environmental and economic factor was considered for optimum site selection. Comparative evaluation among the candidate sites was done by ordinal scale and thus the optimum site was selected.

Twenty six subject drove screws with a screw driver into thick wooden sheet at three vertical and horizontal locations. Subjects drive screws for 3 minutes at each location and they assessed the conditon using the psychophysical scale. An ANOVA showed that only vertical location was a signicant factor in determining the pain ratings of various body parts. Driving screws at elbow height on the vertical surface ans with the lower arm close to the body on the horizontal surface were the work locations with the smallest ratings of perceived pain and discomfort. Wearing gloves had significant effects on reducing the pain of the hand.

본 연구는 환경지리정보시스템을 활용한 활용하여 수질오염방지시설의 입지 결정요인을 분석하여 적정입지를 선정하는 방안을 제시하고자 한다. 이를 위해 수질오염총량제가 가장 먼저 실시된 낙동강 권역을 대상으로 환경지리정보시스템을 구축한 후 1) 수질오염방지시설의 처리용량에 영향을 미치는 오염원, 2) 수질오염방지시설의 입지와 오염원 배출량간의 관계를 분석하여 향후 어떤 오염방지시설을 어디에 입지시킬 것인가에 대한 정책대안을 제시하였다. 분석결과, 1) 수질오염방지시설의 처리용량 결정에 가장 큰 영향을 주는 오염원은 산업폐수발생량으로 판명되었으며, 2) 수질오염방지시설의 입지에 가장 큰 영향을 미치는 오염원은 산업체의 수로 나타났다. 이에 반해 인구수는 환경시설입지를 제한하는 효과가 있는 것으로 판명되었다. 또한, 경상북도 낙동강 중 상류 유역의 경우 주 오염원인 축산오염원에 대한 대처가 가장 미흡한 것으로 나타나 앞으로 축산오염원의 처리가 가장 시급한 것으로 판단된다. 본 연구는 장차 수질오염방지시설의 입지를 선정하는데 활용될 수 있을 것이며, 각 지역의 오염 특성에 따라 수질오염방지시설을 입지를 결정하는데 크게 기여할 수 있을 것으로 기대된다.

The main current in the pathology of oriental medicine is composed of etiologic factor, pathogenesis and clinical manifestation. The access of a disease is consist of etiologic factor, location of the lesion, nature of the disease and patient's condition. The nature of disease and the property of a drug are inseparably related to each other. The nature of disease is composed of six exogenous factors, cold and heat, deficiendy and excess, Yinyang and pain. Cold nature is divided into cold symptom due to excess and asthenia cold, fever nature is divided into sthenic fever and asthenic fever. According to the location, cold and heat can be subdivided into heat in the upper and cold in the lower, cold in the upper and heat in the lower, exterior cold and interior heat, exterior heat and interior cold. Yin syndrome characterized by hypofunction of the viscera is generated from insufficiency of yang-qi, excess of yin-coldness, deficiency of both qi and the blood.

The purpose of this study was to analyze the difference in bakery choice attributes according to consumers' general characteristics and purchasing behavior. Among 350 questionnaires distributed to bakery consumers, 277 complete questionnaires (79.1%) were analyzed. Bakery choice attributes were classified into five factors: "environment and image", "bakery product features", "location", "employee service", and "price and sales promotion"; the mean scores of these factors' importance levels were 3.59, 3.58, 3.49, 3.36, and 3.00, respectively. Males considered 'employee service' factor significantly more than did females. Further, the importance level of 'employee service' factor was significantly greater as consumer's age increased. The importance levels of 'bakery product features' and 'employee service' factors were considered significantly more by consumers who spent KRW10,000-15,000 than those who spent KRW5,000 or less. 'Price and sales promotion' was considered to be more important by consumers who obtained information from the Internet than from the TV and radio. 'Location' factor was considered to be more significant as purchasing frequency increased. Such differences in importance level of bakery choice attributes according to consumers' gender, age, job, and purchasing behavior should be considered and applied to the development of marketing strategies targeted at consumers.
