  • Objectives : The researcher had investigated the efficacy of ginseng using Microneedle Therapy System (MTS) and confirmed the effect of ginseng Cold Process (CP) soap just before and after washing face. The purpose of this study was to find out what kind of effect appeared through a period of 6 weeks when environmental factors were involved using ginseng CP soap. Methods : The researcher selected 47 subjects, 37 as the experimental group and 10 as the control group. The researcher asked participants to wash their face twice a day in the morning and evening using ginseng CP soap, and the period was set for 6 weeks. The researcher had the people who selected as the control group use a commercially available foam cleanser. They performed a skin test before the start of the test, and the change status was continuously investigated 2 weeks, 4 weeks, and 6 weeks after using the soap. Results : In the case of T-zone oil, there was a significant decrease in the use of foam cleansing and ginseng CP soap, and in the case of pores and pigmentation, a significant decrease was observed only in the use of ginseng CP soap. In skin tone change, there was a significant effect in both the experimental group and the control group, but the significance was greatly increased in the case of ginseng CP soap compared to foam cleansing. Conclusions : Ginseng CP soap is considered to be a more suitable cleanser for skin care compared to foam cleansing.

  • The concept of the Metaverse has been around not only for play but also for daily use. The interest in Metaverse is increasing, and various industries such as medicine, media, and financial started to use the new technology for diverse purposes. In addition, interest in the Metaverse is increasing in the architectural industry, but not much research has been done yet. Recently, some studies started to study focusing on the architectural design of Metaverse and the technological characteristics of Metaverse. However, there are limited studies about the utilization of the Metaverse in the architectural design process or construction process. From this perspective, the study aims to analyze the applicability of the Metaverse in the architectural design process through Metaverse case studies. In order to accomplish the research goal, the study classified user experience and technology of Metaverse in the literature review and Metaverse use in other industries such as commercial, medical, media entertainment, and construction industry. Then, this study analyzes six representative Metaverse platforms according to the application of Metaverse in the architectural design process. Finally, this study discussed the future direction and potential of Metaverse application in the Architectural design process.

  • The focus of this study is on the accuracy in quantity estimates made by BIM for materials needed during construction. BIM-Revit Architecture 2014 is utilized to establish the information for an actual case to conduct estimates for the amount of reinforced concrete and formwork needed. The actual case is with a total construction area of 5,438 square meters and a total floor area of 31,623 square meters. The building commenced in December 2012 and the major structure has been completed in 2014. It is a RC structure with 4 stories underground, 12 stories above and 3 roof floors. The result shows that both of the quantity estimates of reinforced concrete and formwork are higher than that of actual use in the case. The estimate of reinforced concrete is higher than that of actual use by 2.18%, while the estimate of formwork is higher than that of the actual use by 13.04%. The results indicate that the estimate of reinforced concrete made by BIM has high accuracy, but the accuracy of the formwork estimate still needs improvement.

  • 가변성 관리는 시스템이 어느 정도까지의 복잡성을 처리할 수 있는가를 정의하는 가장 중요한 기준이다. 대부분의 요구 공학 연구에서는 시스템이 동작하는 환경에 대해 많은 부분을 간과하거나 추측하는 수준에 그치고 있다. 그러나 실시간 시스템에서는 본질적으로 변화하는 컨텍스트를 관찰하고 조정하는 것은 중요한 요소이다. 본 연구에서는 i* 목표 모델, 문제 프레임, 유즈 케이스 맵, 라이브 시퀀스 차트를 활용하여 다양한 컨텍스트에 적합한 요구사항을 식별할 수 있는 프레임워크를 제안하며 스마트 그리드의 실시간 가격 정책 변화 시스템을 사례 연구로 활용하여 제안하는 프레임워크를 단계별로 자세하게 설명한다. 사례 연구를 통해 제안방법에서 유즈 케이스 맵과 라이브 시퀀스 차트를 활용한 시나리오 정교화 과정이 초기 컨텍스트 분석 및 검증에 도움을 주는 것을 보여주며 장애물 및 충돌 분석을 위한 요구사항을 정교화함으로써 요구공학 엔지니어들이 시스템의 건장성을 증가시키는 것을 도와줄 수 있음을 증명한다. 이처럼 제안하는 프레임워크는 이론적인 방법과 실증적인 사례를 통해 평가된다.

  • The purpose of this study is to calculate the energy consumption rate based on data regarding energy use in office buildings, and to confirm the general characteristics of energy consumption. The energy consumption rate of the building is calculated by dividing the energy consumption by the floor area. The energy consumption rate of small-sized office buildings was calculated as $101.48{\sim}201.55kWh/m^2{\cdot}year$ and in the case of medium-sized buildings, the range was $92.77{\sim}177.89kWh/m^2{\cdot}year$. In the case of small buildings, it was found that the energy consumption was $73.24kWh/m^2{\cdot}year$ in electronic device, $34.31kWh/m^2{\cdot}year$ in hot water supply, and $18.37kWh/m^2{\cdot}year$ in heating. In the case of medium-sized buildings, electronic devices was $73.08kWh/m^2{\cdot}year$, lighting was $18.35kWh/m^2{\cdot}year$ and heating, $15.37kWh/m^2{\cdot}year$. In all of the study buildings, the peak heating energy use was observed from 8:00 a.m. to 10:00 a.m during the winter, and the peak power management was required. Energy use at and around the midnight hour is confirmed to be 40~60% of weekly working hours, so it is necessary to manage power use at night time as well as during the day. In order to improve the accuracy of future studies, it is necessary to make efforts to secure the data with standardized energy measuring units for the various type of buildings.

  • 본 연구의 목적은 경북 영양군 요원리를 사례로 경지개간과 연계한 토지이용 변화와 특성을 분석하는 것이다. 나타난 결과를 보면 다음과 같다. 첫째, 경지개간은 대부분 19세기후기가지와 1960년대에 이루어졌다. 논의 개간은 물을 구할 수 있는 계곡에서, 밭의 개간은 1960년 이전에는 취락과 가까운 지점에서 그 이후로는 경사도가 낮고 넓은 구릉지를 중심으로 개간하였다. 둘째, 상업적 농업 이전인 19n년대의 토지이용은 감자. 조, 콩 등의 잡곡 중심이었으나 1970년대 이후로는 고추. 담배, 고랭지 채소 등의 상업적 작물로 대체하였다. 셋째, 토지이용 변화(작물선택)의 주도적인 세력은 산지주민들이다. 본 연구는 다음과 같은 의의가 있다. 첫째, 경지개간과 연계하여 토지이용변화 및 특성을 설명하였다는 것이다. 둘째, 소규모 마을을 대상으로 미시적으로 연구하였다는 점이다.

  • Reversible posterior leukoencephalopathy syndrome (RPLS) is an acute encephalopathy, usually characterized by seizures, visual disorder, mental change and reversible posterior white and gray matter lesions on brain magnetic resonance imaging (MRI). Conditions commonly associated with RPLS include acute renal failure, eclampsia, hypertension, immunosuppresion state, and use of intravenous immunoglobulin or chemotherapy, and additional contributing factors. We report the case of RPLS associated with cyclosporine use in lupus nephritis. In this case, it was not clearly elucidated which was main cause of RPLS. We could think RPLS developed maybe due to combined effect of cyclosporine and lupus nephritis.

  • Although some CASE tools supported conceptual data design, they required for users too much preliminary knowledge to learn how to use and handle them. In addition, in a number of studies on conceptual data design with natural language, they claimed passive participation for users with conforming to messages predefined by CASE tools. As an alternative to these traditional CASE tools, we proposed an ERD formulator for automated data design tool, called ERDF, so that even ordinary users, not necessarily data modeler, are capable of formulating ERD on business requirements by use of ERDF. We, first of all, introduced NSM as the standard methodology. We also designed the structure of ERDF including main controller, input controller, operation controller, regulation controller, schema controller, and output controller. We then defined conceptual domains and basic operations to lay down schema operations as well as sentence rules to handle input sentence in natural language. To get an ERD that is faithful to business requirements, we laid out supplementary design for dialogue and confirmation of soundness and completion.

  • Although many prosthetic materials exist for fabrication of implant-supported telescopic overdentures, available materials have not been thoroughly evaluated from a functional standpoint. This case report describes the use of polyaryletherketone (PAEK) based polymer for an implant-supported telescopic overdenture, a seldom used material in dentistry. This material is lighter than traditional materials, can accommodate changes in retentive forces, and is an easily retrievable by CAD/CAM fabrication. This case highlights the possibility of using new polymer materials for implant-supported telescopic overdentures.
