Facility Management (FM) phase in building lifecycle management is the most crucial phase concerning building value and life cycle cost management. Nevertheless, systematic and rational FM process is not yet constructed, leading to failure of facility value and cost management from accurate and proactive FM. This is because there has been minimal approach regarding construction of optimal FM process based on rational FM data analysis. The purpose of this study is to provide optimal FM process with quantitative FM data analysis method using spatial data. This study investigated existing FM data structure and derive the limitation of it from both expert interview and practical FM material analysis. As a solution for this limitation, this study provided optimal FM process with MTBF (Mean Time Between Failure), which is quantitative FM data analysis method. The effect of the provided process was validated with a case study. It is expected that this process allows rational and objective FM data analysis, resulting in accurate and proactive FM. And it is expected that it can be used as a useful basic data for developing an effective system for the FM process.

Low supply of water is generally the most serious factor limiting rice production. The experiment was conducted to identify the reasonable method for minimum irrigation under ridge direct seeding on dry paddy, at National Honam Agricultural Experiment Station, RDA in 1996. The results showed that the reduction ratio of irrigation water was high in order of furrow irrigation at 15-day>furrow irrigation at 10-day>flooding irrigation at 10-day>, and furrow irrigation at 5-day intervals. However, milled rice yield was high in the furrow irrigation at 5-day intervals and in flooding irrigation at 10-day intervals due to high ripened grain as compared with other treatments indicating two treatments were the most reasonable irrigation methods in terms of saving the labor cost and water supply as well as the admittable yield performance.

Purpose: This study aimed to examine social networking service (SNS) use and recommended information utilization (SURU) according to the food-related lifestyles (FRLs) of consumers and analyze how the interaction between the FRL and SURU affects the practice of eating alone and visiting restaurants. Methods: Data on 4,624 adults in their 20s to 50s were collected from the 2021 Consumer Behavior Survey for Food. Statistical methods included factor analysis, K-means cluster analysis, the complex samples general linear model, the complex samples Rao-Scott χ² test, and the general linear model. Results: The following three factors were extracted from the FRL data: Convenience pursuit, rational consumption pursuit, and gastronomy pursuit, and the subjects were classified into three groups, namely the rational consumption, convenient gastronomy, and smart gourmet groups. An examination of the difference in SURU according to the FRL showed that the smart gourmet group had the highest score. The result of analyzing the effects of the FRL and SURU on eating alone revealed that both the main effect and the interaction effect were significant (p < 0.01, p < 0.001). The higher the SURU, the higher the frequency of eating alone in the convenience pursuit, and gastronomy pursuit groups. The main and interaction effects of the FRL and SURU on the frequency of eating out were also significant (p < 0.01, p < 0.001). In all the FRL groups, the higher the SURU level, the higher the frequency of visiting restaurants. Specifically, the two groups with convenience and gastronomic tendencies showed a steeper increase. Conclusion: This study provides important basic data for research on consumer behavior related to food SNS, market segmentation of restaurant consumers, and development of marketing strategies using SNS in the future.

The purpose of this research is to provide the rationality of placement of game objects using the space analysis for game map so that the game designers can find out the proper position for each object in the map. The significance of this research is beyond the limitations of the existing research using Space Syntax theory is confined to the analysis of the behavior of players in the map, this research suggest the method of the efficient placement of game objects in level design step. This paper as the worth of the industry is expected to be able to reduce the repetitive tasks that may occur during game level design steps. Through this, it is also expected by reducing game development period and development costs in accordance with the reasonable placement of game objects.

For the successful IT operation outsourcing there need appropriate metrics on which both of the service clients and provider agree. The metrics are used to set up the service level objectives, which are manifested in the service level agreement with price. A study of metrics is necessary for the following reasons: First, most of the metrics used today were introduced in the early years of computers and are not satisfactory to both of the service providers and clients. Second, metrics represent the performance of system components but not end-user satisfaction. Third, because the service provider leads the outsourcing agreement, the objectives are specified more favorable to the provider. The objectives should be based on metrics that both sides fully understand and agree on.

In January 2020, the National Assembly passed the revisions of three bills which ease regulations on the use of personal information. The revised laws include the launch of an independent supervisory body, the arrangement of redundant regulations, and regulations for the development of the data economy. This paper analyzes the content and meaning of each law of the Three Revised Bills that Ease Regulations on the Use of Personal Information. And the future challenges outline three aspects: the establishment of a system to ensure the right to informational self-determination of privacy concerns, the establishment of a certification system and the presentation of reasonable guidelines, and the expectation of professional performance by the Personal Information Protection Commission.

In an information society, privacy protection is one of the most important ethical issues. In medical institutes in which personal medical information is collected and stored, in addition, a privacy breach can cause a serious damage on personal lives. This study attempted to develop privacy concern measurement tool in personal medical information to measure patients' concern on their medical information from medical service consumers' perspective and verify its validity. For this, privacy concern measurement tool in personal medical information was developed based on the results of previous studies. After performing Exploratory Factor Analysis(EFA) and Confirmatory Factor Analysis(CFA) on the measurement tool, its reliability and validity were verified. It appears that the measurement tool would be useful in developing decent privacy protection policy after investigating citizens' concern on the protection of personal medical information and domains they are interested in. For medical institutes as well, they would be helpful in coming up with a reasonable plan after figuring out problems in the protection of personal medical information and current status.

우리나라에서는 1961년의 제정 하천법을 통하여 하천을 사용하고자 하는 경우에는 관리청의 허가를 득해야 함을 명시적으로 규정한 이래 현재까지 하천수의 사용을 허가제로 운영하고 있다. 하천수 사용을 위한 제도가 정비된 지 반세기 이상의 세월이 흘렀지만, 이를 둘러싼 분쟁이 끊이지 않고 있는 상황이 반복되고 있다. 이로 인하여 상호간의 불신과 갈등이 증폭되고, 사회적 갈등비용이 증가하며 제도 그 자체를 불신하는 움직임마저 나타나고 있다. 특히 우리나라와 같은 댐저수와 하천수 의존형 물 관리에서는 댐용수와 하천수의 합리적인 배분이 매우 중요하다고 할 수 있다. 물분쟁의 주된 유형은 지자체와 물공급을 담당하고 있는 한국수자원공사와의 갈등이 대부분이다. 분쟁의 유형도 단순한 취수시설 확장에 관한 사항에서부터 물수지분석의 방법에 관한 사항까지 복잡다양하게 얽혀있다. 이와 같은 물분쟁은 물론 긴 역사속에서도 존재하여 왔지만 제도적인 틀을 정비함으로써 갈등상황을 감소시키고 나아가 하천과 물의 효율적 관리 등 국가적 차원의 긍정적 요인을 도출하는 것이 주요한 목적이라고 할 수 있다. 또한 2009년 하천법 개정을 통하여 하천수 사용허가의 세부기준을 정하도록 규정되어 있으나 현재에 이르도록 별다른 진전을 보이지 못하고 있다. 본 연구에서는 하천법 제50조4항(아울러 시행령 제56조2항 및 시행규칙 제28조4항)에서 규정하고 있는 하천수 사용허가의 세부기준을 작성하기 위하여 시도되었다. 세부기준은 하천수를 사용하고자 하는 물 사용자와 하천수 관리청의 역할을 비롯하여 책임과 권한의 관계가 분명하게 정립될 필요가 있다. 따라서 기존 하천수 사용허가 행정을 면밀히 분석하였고, 실제 하천수 사용허가 행정업무를 수행하고 있는 4대강(한강, 금강, 영산강, 낙동강) 홍수통제소 실무자와의 수차례에 걸친 논의를 거쳐 완성되엇다. 세부기준(안)은 9개장 43개조항으로 이루어져 있으며, 하천수 사용허가 행정 전반을 범위로 하고 있다. 본 연구를 통하여 작성된 하천수 사용허가 세부기준이 입법화된다면 하천수 사용허가를 둘러싼 갈등상황의 감소가 예상되며, 보다 투명한 하천행정을 기대할 수 있을 것이다. 또한 앞으로 물수지분석 방법이나 용도별 하천수 사용요금 등에 대한 현실적인 대안이 마련된다면 보다 선진적인 하천행정을 수행할 수 있을 것으로 기대된다.
