This paper proposes an evaluation model for internet shopping mall business by defining its characteristics and evaluation criteria. We analyzed the characteristics of internet shopping mall business environments and classified the business into four major categories. We derived the evaluation criteria which can evaluated all categories comprehensively. The proposed criteria are cost, netizen, technology, transaction, and marketing, each of which gives a significant impact on the business profitability. Based on these criteria, a quantitative evaluation method was developed. We also proposed a penta-classification scheme which can be used to identify the overall characteristics shape of each internet shopping mall business site. An actual application of our evaluation model was illustrated in order to show that our proposed model may be used in the real business sites.

최근 공통주택 재건축과 리모델링 사업은 경제성만을 고려하여 사업이 추진되고 있다. 그러나 경제성 이외에도 환경성은 사업계획 및 수행에 있어서 중요한 고려요소이다. 따라서 재건축과 리모델링 사업의 환경성과 경제성을 함께 평가되어야 하며, 정량적인 평가방법에 의해 의사결정의 도구로써 활용할 수 있는 방법이 필요하다. 이에 본 연구는 공동주택 재건축과 리모델링 사업의 환경성 및 경제성을 통합 및 평가할 수 있는 모델을 제시하고자 한다.

훈제연어의 L. monocytogenes에 대한 식중독 안전관리 방안 마련 및 위해평가 수행 등을 위하여 성장예측모텔을 개발하였다. 미생물 성장예측모델 개발 방법은 대상 식품 및 환경 조건에 따라 다양하며 통계적으로 유용한 모델을 사용하여야 하기에 본 연구에서는 미생물 성장예측모델 개발에 널리 사용되어 그 적용성이 검토된 Gompertz model과 Polynomial model equation을 이용하여 훈제연어의 L. monocytogenes 최대성장속도(SGR) 및 유도기(LT)에 관한 예측모텔을 개발하였다. 개발된 모델의 적합성 평가를 위해 $B_f$와 $A_f$ factor를 산출하였고 최대성장속도(SGR)의 경우 0.98, 1.06, 유도기(LT)의 경우 1.60, 1.63으로 나타나 유도기의 적합성이 최대성장속도에 비하여 떨어지는 것으로 확인되었다. 본 연구에서 개발된 훈제연어에서의 L. monocytogenes 성장속도에 관한 모텔은, 수산업, 특히 훈제연어 생산, 가공, 보관 및 판매업에 다양한 방면으로 활용 가능할 것으로 판단되며, 더욱 정확한 예측모텔 개발을 위해서는 다양한 변수에 따른 미생물의 성장패턴 변화 등에 관한 연구가 추가적으로 시행되어야 할 것으로 생각되어 진다.

As diverse online information services are introduced and the use of them are increasing, the importance of the quality control over the online information services is also increasing. Therefore, studies are being attempted to derive quality evaluation models for online information services, but these showed many limitations. In order to overcome the limitations of the previous studies and create more appropriate quality evaluation model, this study analyzed 408 data collected through the interviews with the users of Korea national online information services (NDSL, NTIS) using content analysis and the coding method of ground theory. Through the analysis, we identified the quality evaluation model (13 elements, 6 dimensions) of online information services and the description and insights of each elements. And the priorities of the most significant element(amount of information) and other key elements(such as the usefulness of the information, the diversity of the field, etc.) were figured out through the frequency analysis. Through these inductive methods based on the responses of users, the quality control model could be derived, which is different from the previous researches. This study is the first study which derived the quality evaluation model of online information service through the inductive way based on 408 interview responses from users. Therefore, the results of this study will be helpful to the post researchers who conduct studies on the quality of online information service, etc. Moreover, the results of this study are expected to provide references of frame for decision-making of working-level officials who have to manage the quality of online information services.

This paper introduces a feasibility evaluation method for prognosis systems based on an empirical model in nuclear power plants. By exploiting the dynamical signature characterized by abnormal phenomena, the prognosis technique can be applied to detect the plant abnormal states prior to an unexpected plant trip. Early $operator^{\circ}{\emptyset}s$ awareness can extend available time for operation action; therefore, unexpected plant trip and time-consuming maintenance can be reduced. For the practical application in nuclear power plant, it is important not only to enhance the advantages of prognosis systems, but also to quantify the negative impact in prognosis, e.g., uncertainty. In order to apply these prognosis systems to real nuclear power plants, it is necessary to conduct a feasibility evaluation; the evaluation consists of 4 steps (: the development of an evaluation method, the development of selection criteria for the abnormal state, acquisition and signal processing, and an evaluation experiment). In this paper, we introduce the feasibility evaluation method and propose further study points for applying prognosis systems from KHNP's experiences in testing some prognosis technologies available in the market.

The purpose of this research was to develop evaluation conformity to operate courses based on CIPP evaluation model dedicated to approval of training organizations. In order to achieve the goal, the researchers scrutinized related documents and precedent studies, initiated the draft for evaluation conformity to operate courses and secured validity for evaluation conformity initiated through Delphi Method survey. To secure validity for evaluation conformity, the researchers conducted two Delphi Method surveys of an expert panel of 22 professionals from relevant fields including officials from the Ministry of Land, Infrastructure and Transport, researchers from Korea Transportation Safety Authority, instructors from approved training organizations and officials from industries. Through the surveys, the researchers determined 4 evaluation areas, 13 evaluation items and 52 evaluation indexes as the evaluation conformity to operate courses for aircraft maintenance mechanics. On top of that, the researchers established evaluation system in the courses for aviation professionals (aircraft maintenance mechanics), and suggested a follow-up studies regarding managing the quality of education.

This study aims to evaluate the feasibility of remodeling business by predicting the future price of apartment house after remodeling using Hedonic Price Model. The data concerning such 9 independent variables as location, unit size, unit plan, landscape, parking, the number of elapsed years after completion, number of units, mechanical performance, interior from 25 regions in Seoul metropolitan city were collected and evaluated by established evaluation criteria. The coefficients affecting the price of apartment unit were made by Ivay of linear multi-regression and put into Hedonic Price Model. The feasibility evaluation model for apartment was made and verified by data of remodelled apartment. The predicted results using suggested evaluation model coincide with actual apartment market situations.

Green Building Certification System currently going into effect is a static evaluation model. Therefore, as far as the sustainable development of certification system is concerned, further long-term evaluation is required. The main purpose of this study is to offer a model in a way of developing and verifying a dynamic model in Green Building Certification. A dynamic model development has been given System Dynamics based on the causal structure. Thus, this study focused on searching the causal structure of certification criteria and verifying the reality of the model through simulation processing after developing a model. In conclusion, the development of dynamic evaluation method can be attributed to systematic evaluation for the criteria of Certification System.
