군 시설물은 80년대 이후 현대화 계획 및 군 복지의 향상 등으로 인해 그 수가 급격하게 증가하였다. 그러나 이렇게 증가한 시설물에 대해 체계적인 유지관리가 이루어지지 못하여 노후화되면서 이러한 노후시설의 성능향상이 필요하게 되었다. 노후 시설물의 성능향상 방안은 재건축과 리모델링으로 나눌 수 있다.그러나 표준 리모델링 범위 내에서는 리모델링이 더 경제적이라는 연구결과에도 불구하고 군 시설의 리모델링은 성능 향상의 수단으로써 재건축과 동등하게 고려되고 있지 않다. 따라서 본 연구에서는 건축물의 생애주기 동안의 성능 변화와 리모델링 필요 범위의 관계성에 착안하여 재건축보다 리모델링이 경제적인 특정시점(SPT)에 리모델링을 선택하는 방식의 리모델링 프로세스 모델(RPM)을 제안한다. 또한 군 시설물의 자료에 근거하여 이를 위해 필요한 현실성 있는 내용연수와 기능성 평가기준을 함께 제시한다. 이 RPM을 통해 기존프로세스에서 발생하는 안전성에는 문제가 없으나 기능성에 문제가 있는 시설물들이 적절한 리모델링 시기를 놓쳐 어쩔 수 없이 재건축을 하게 되는 사례를 방지할 수 있게 하였다. 또한 준공시기와 유형이 다른 시설물을 관리하는 입장에서의 재건축/리모델링 선택의 의사결정을 보다 간단하게 할 수 있는 가능성을 제시하였다. 이러한 리모델링에 보다 초점을 맞춘 프로세스를 통해 예산절감 효과뿐만 아니라 재건축으로 인한 사회적 낭비를 줄이는데 기여할 수 있을 것이라 판단된다.

This study focused on the production and usability evaluation of smart outdoor jackets that are designed to provide convenience to middle-aged people by embedding devices for lighting and location tracing. The results were as follows. 1. Jacket power supplier was a assembled system composed of battery, charger, controller and switch. A solar cell was attached on the upper arm, and a wire type EL on the center line of a raglan sleeve along with a GPS on the left sleeve with a transparent vinyl pocket. The total weight of the jacket embedded with devices was 385-520g. 2. Operation of function, activity, acceptability, safety, convenience for device use, appearance, practical maintenance were selected based on an analysis of evaluation criteria of previous smart wear research. Criteria were narrowed to three major categories of satisfaction, appearance and maintenance. 3. Use satisfaction criterion consisted of wearable device functionality and physical, psychological use convenience. The evaluation indicated actual functionality. EL functions were especially effective and necessary. Convenience of use showed that a smart jacket was thought to be safe and the size was moderate regardless of age and gender. Outer appearance was satisfactory and respondents praised the color. The practical maintenance evaluation indicated that there was no challenge in doing the laundry since the solar battery and GPS were detachable. The practical use of smart outdoor jackets confirmed by fabric that was washable and dried quickly.

This study aims to suggest the proper neck-width of slim-fit jackets according to numbers of jacket buttons from an one-button jacket to a four button jacket for men in their 30's. The researchers carried out both an appearance evaluation and a movement functionality evaluation. When analyzing the appearance evaluation, there were meaningful differences. The one-button jacket showed a high score on the back-neck width of +2.4cm. The two-button jacket and the three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. The result of movement functionality evaluation was not related to the appearance evaluation, and showed no meaningful difference. The one-button jacket and two button jacket showed high scores on the back-neck width of +2.4cm. The three button jacket showed a high score on the back-neck width of +1.4cm. The four-button jacket showed a high score on the back-neck width of +0.4cm. In analyzing both results, the study suggests that the proper front neck-width and that of the back-neck width of +2.4cm be for the one-button jacket, the back-neck width of +1.4cm be for the two-button jacket and the three-button jacket, while the back-neck width of +0.4cm be for the four-button jacket.

Retail firms have begun to pursue the marketing strategies, which stimulate consumers' sensibility and lead people to purchase their products. The visible effects of visual merchandising (VM) arouse consumers' interest and play an effective role in having busy people efficiently choose products. Apparel retail stores such as SPA use the offline store to be the experiential environment of their branding. Consumers' sensitivity and response toward various visual merchandising strategies needs to be accessed. The purpose of this study is to identify VM consciousness and VM evaluation attribute factors. Relationship of such variables with other variables were accessed. As consequence variables, product satisfaction and unplanned purchase behavior were included in the study. An empirical survey data was collected from men and women of various ages. Results indicated that VM consciousness and VM evaluation attribute factors were not correlated with consumer demographic variables. VM evaluation attributes were factored into appropriateness, attractiveness and functionality dimensions. Clothing involvement and brand orientation significantly influenced product satisfaction and unplanned purchase. The direct and indirect effect (via VM consciousness) were significant. For unplanned purchase, brand orientation only had indirect effect. The influence of VM evaluation attribute factors were significant. Appropriateness had stronger effect on product satisfaction whereas attractiveness had stronger effect on unplanned behavior. Functionality dimension had only indirect effect on product satisfaction but did not show significant direct and indirect effects on unplanned purchase. This study identified the pivotal role of VM consciousness in various shopping and purchasing circumstances in offline retail store of apparel brands.

In this study, we attempted to enrich cyclo-His-Pro (CHP) using enzymatic hydrolysis of yeast and to evaluate the functionality of yeast hydrolysate (YH)-enriched CHP. Flavourzyme offered a better performance in enhancing CHP content than other proteases. The CHP enrichment conditions were optimized as follows: addition of 1% Flavourzyme, 48-h incubation at 60oC, and pH 6.0. The CHP content significantly increased by 20-fold after ultra-filtration (UF). Maximal CHP translation was obtained after heating for 8 h at 50oC and pH 7.0. YH showed poor foaming capacity between pH 3.0 to 9.0. The emulsifying activities of YHs were slightly higher at near acidic pH. Increase in heating temperature and time resulted in decreased CHP content. The results indicate that YH is more heat stable after UF. Therefore, the CHP in YH after UF can be used as a food additive with physiological CHP activity and high heat stability.

The purchase-related responses of MZ generation consumers may vary depending on the environmental factors of the fitting room. Therefore, this study extracted and systematized fitting room characteristics in the retail fashion environment. In-depth interviews were conducted with a total of 50 informants to collect data on the experience of using the fitting room. Then, a qualitative analysis was performed. First, results confirmed that the environmental factors of the fitting room include physical (spatiality, functionality, comfort, and convenience) and human (interactivity and congestion) aspects. Next, additional analysis was performed on functionality and interactivity to clarify the influence of environmental characteristics of the fitting room. These factors were classified into qualitative categories. The study results confirmed that, in the case of functionality, preferred lighting and mirror factors vary depending on the clothing product type, the place and situation for wearing, and individual characteristics. Furthermore, regarding interactivity, the preference for the presence of sales staff or companions differed according to personal traits and the need for additional information and evaluation. The study provides valuable information for effective fitting room space planning for offline fashion stores to meet the needs of MZ generation consumers.

The Common Criteria (CC) philosophy is to provide assurance based upon an evaluation of the IT product or system that is to be trusted. Evaluation has been the traditional means of providing assurance. It is essential that not only the customer' srequirements for software functionality should be satisfied but also the security requirements imposed on the software development should be effectively analyzed and implemented in contributing to the security objectives of customer's requirements. Unless suitable requirements are established at the start of the software development process, the re suiting end product, however well engineered, may not meet the objectives of its anticipated consumers. By the security evaluation, customer can sure about the quality of the products or sys tems they will buy and operate. In this paper, we propose a selection guide for If products by show ing relationship between security engineering and security evaluation and make help user and customer select appropriate products or system.

Evaluation of retrieval systems is mostly limited to laboratory settings and rarely considers changes of performance over time. This article presents an evaluation of retrieval systems for internal Web site search systems between the years 2006 and 2011. A holistic evaluation methodology for real Web sites was developed which includes tests for functionality, search quality, and user interaction. Among other sites, one set of 20 Web site search systems was evaluated three times in different years and no substantial improvement could be shown. It is surprising that the communication between site and user still leads to very poor results in many cases. Overall, the quality of these search systems could be improved, and several areas for improvement are apparent from our evaluation. For a comparison, Google’s site search function was also tested with the same tasks.
