This study is targeted at the people who live in Jecheon. It investigated the general term concerning the preservation and reuse of architectural heritage, the awareness of local architectural heritage, and the civic consciousness about the relationship between architectural heritage and townscape. And, it is aimed to be used as a basic data for the preservation and reuse of architectural heritage and townscape in Jecheon. This study was conducted using the survey and the statistical analysis. The result are as followings. Firstly, when the policy related to the preservation and reuse of architectural heritage in Jecheon is to be made and proceeded, it should actively promote and reflect the views of the citizens. Secondly, it should be to develop the available utilization programs and to find the method to increase the accessibility of architectural heritage. Thirdly, it should be considered the method which can give the economic benefits to owners and the enjoyment of culture to the citizens. Lastly, the long term plan will be required for a distinctive townscape in Jecheon. And, when modern architecture adjacent to the architectural heritage is built, we should be considered the design which can be expressed the historicity of architectural heritage.

성적공개용으로 모은 네 자리 숫자 비밀번호들의 재사용에 관한 1차 조사 연구의 보완과 정도를 높이기 위해, 2012부터 2017년까지, 6년 동안 1차 조사의 2배 가까운 2392개를 수집하는 2차 조사를 실시하였다. 분석 결과, 비밀 번호사용개수가 많아지면 재사용 비율이 높아질 수 있다는 것, 재사용 시 사용번호 개수가 최대 4개인 점과 같은 사용처라도 개인별 성향 차이가 존재할 수 있다는 1차 조사 때 얻을 수 없던 결과들이 포함되는 성과를 얻었다. 이러한 2차 조사 결과들은 숫자뿐 아니라 문자, 특수문자까지 혼합하여 사용하는 일반 패스워드들의 재사용에 관한 외국의 연구결과들과도 대부분 유사하였다. 본 2차 사례 연구결과, 자료 수집이 불가능한 국내 패스워드들의 재사용실태를 간접적으로나마 유추할 수 있는 계기를 제공하게 되었으며, 주기적변경과 같은 패스워드 보안을 위한 관리규약은 오히려 재사용 비율을 높일 수 있다는 외국의 연구 사례가 국내 상황에도 적용될 수 있을 것이라는 추론의 가능성도 얻게 되었다.

In this paper, we have studied how to reuse common data link software by applying software product line engineering. Existing common data link software performed different stages of design, implementation, and testing without sharing the accumulated knowledge of different developers. In this situation, developers agreed that sharing the assets of each project and reusing the previously developed software would save human and time costs. Even with the initial difficulties, the common Data Link is a continually proposed project in the defense industry, so we decided to build a product line. The common data link software can be divided into two domains. Among them, the initial feature model for the GUI software was constructed, and the following procedure was studied. Through this, we propose a plan to build a product line for core assets and reuse them in newly developed projects.

Water cycle within the human civilization has become important with urbanization. To date, water cycle in the eco-system has been the focus in identifying the degree of water cycle in cities, but in practicality, water cycle within the human civilization system is taking on an increasing importance. While in recent years plans to reuse water have been implemented to restore water cycle in cities, the effect that such reuse has on the entire water cycle system has not been analyzed. The analysis on the effect that water reuse has on urban areas needs to be go beyond measuring the cost-savings and look at the changes brought about in the entire city's water cycle system. This study uses a SWAT model and water balance analysis to review the effects that water reuse has on changes occurring in the urban water cycle system by linking the water cycle within the eco-system with that within the human civilization system. The SWAT model to calculate the components of water cycle in the human civilization system showed that similar to measured data, the daily changes and accumulative data can be simulated. When the amount of water reuse increases in urban areas, the surface outflow, amount of sewer discharge and the discharged amount from sewage treatment plants decrease, leading to a change in water cycle within our human civilization system. The determinant coefficients for reduced surface outflow amount and reduced sewer discharge were 0.9164 and 0.9892, respectively, while the determinant coefficient for reduced discharge of sewage treatment plants was 0.9988. This indicates that with an increase in water reuse, surface flow, sewage and discharge from sewage treatment plants all saw a linear reduction.

This study was performed to identify effects of hospital selection factors on patient satisfaction and reuse intention. For this purpose, a survey was performed subject to outpatients and inpatients in 10 hospitals located in Busan district from March 7, 2013 to June 21, 2013 and total 447 copies were used as final study data. As results of this study, it was found that among the hospital selection factors of outpatients, internal conditions and medical service gave effects to patient satisfaction and internal conditions, service of medical staffs and medical service gave effects to reuse intention. It was found also that among the hospital selections factors of inpatients, internal conditions, service of medical staffs and medical service gave effects to patient satisfaction and external conditions, internal conditions, service of medical staffs and medical service gave effects to reuse intention. It was suggested that in the effect of patient satisfaction on reuse intention, both inpatients and outpatients gave the effect and thus higher patient satisfaction was related to higher reuse intention. Therefore, instead of hospital-centered medical treatments, hospitals should restructure its medical and service systems that are patient-centered. Also, it is necessary for the hospital managers to recognize that patient satisfaction is an important factor in increasing its profit.

Statement of problem: Resonance frequency analysis is evaluated as the non-invasive and objective method for the evaluation of implant stability and has been increasingly used. It is necessary to evaluate the factors affect the ISQ measurement stability. Purpose: This study was performed to evaluate the effect of the autoclave sterilization and reuse of $Smartpeg^{TM}$ on ISQ measurement. Material and methods: $SmartPeg^{TM}$ (Integration Diagnostics Ltd., $G\ddot{o}teborg$, Sweden) of autoclave group (A) was autoclave sterilized 9 times and $Smartpeg^{TM}$ of reuse group (R) was reused 9 times. Ten $SmartPeg^{TM}s$ were allocated to each group and after each autoclave sterilization and reuse, implant stability quotient (ISQ) values were measured 3 times from the two directions a and b at a right angle. $Osstell^{TM}$ mentor (Integration Diagnostics Ltd. $G\ddot{o}teborg$, Sweden) was used and type 1 (article no. 100353) $Smartpeg^{TM}$ was selected according to $Smartpeg^{TM}$ reference list. Osstem Implant US II future (Osstem Co., Seoul, Korea) in $4.0mm{\times}11.5mm$ was embedded in the self-curing acrylic resin ($Orthojet^{(R)}$, Lang Dental, U.S.A.). Data was statistically analyzed by one-way ANOVA $({\alpha}=.05)$ and scheffe test was done where a significant difference exist. Correlation test was also done between ISQ value and the number of autoclave sterilization or reuse. Results: 1. In autoclave group, the means and sd. of ISQ value before autoclave sterilization were $84.97{\pm}0.41,\;84.93{\pm}0.74$ at direction a and b. There was significant differences between autoclave groups at direction a and b (P=.000). 2. In reuse group, the means and sd. of ISQ value before reuse were $85.40{\pm}0.62,\;85.50{\pm}0.57$ at direction a and b. There was no significant difference between reuse groups at direction a and b (P>.05). 3. There was a weak positive correlation between the number of reuse and ISQ value at direction a and b (${\gamma}=.207$ and .246, P<.01). Conclusion: Within the limitations of this study, the following conclusions were drawn. Till ninth reuse of $Smartpeg^{TM}$, the ISQ measurement stability did not be affected. After twice autoclave sterilization of $Smartpeg^{TM}$ the ISQ measurement stability was affected.

특징 선택은 기계 학습 및 패턴 인식 분야에서 중요한 이슈 중 하나로, 분류 정확도를 향상시키기 위해 원본 데이터가 주어졌을 때 가장 좋은 성능을 보여줄 수 있는 데이터의 부분집합을 찾아내는 방법이다. 즉, 분류기의 분류 목적에 가장 밀접하게 연관되어 있는 특징들만을 추출하여 새로운 데이터를 생성하는 것이다. 본 논문에서는 소프트웨어 재사용의 성공 요인과 실패 요인에 대한 분류 정확도를 향상시키기 위해 특징 부분 집합을 찾는 실험을 하였다. 그리고 기존 연구들과 비교 분석한 결과 본 논문에서 찾은 특징 부분 집합으로 분류했을 때 가장 좋은 분류 정확도를 보임을 확인하였다.
