Given the trend of increased apartment buildings and high-rise buildings, the maintenance of apartment buildings has been set a higher value. For this reason, a total performance evaluation model of the existing buildings has recently been developed. But, it has a lack of the management work analysis. The purpose of this study, therefore, is the management work analysis for items selection of maintenance performance evaluation of apartment buildings. Candidate items of Maintenance performance evaluation was made with the existing literature and business system analysis. Easy systemicity of performance evaluation supplemented doing question to academic experts and housing managers. Finally decided maintenance performance evaluation items are to classify 14 administrative and 15 technical items.

This study aims to propose the comprehensive evaluation of performance multi-family housing. Most of the existing studies for the reproduction have evaluated by the safety of structure. Therefore those pass over the functional factors which is important for the evaluation of residential qualities. This study represents that the reproduction renovation should not be secured the safety of structure but established the quality of lift. And questionnaire asking expert's opinion also supplemented. As a result, the item for examination and the weight for evaluation are suggested in functional deterioration. The results of this study are summarized as follows: 1. Existent redevelopment criteria are not appropriate to decide the environmental comfort, the vital function of housing and the residential management finance. 2. The future criteria have to evaluate the existing environmental comfort, be reconstructed to put first general deterioration. 3. Evaluation elements was extracted throughout the document research, evaluation elements analysis system was separated in residential area, suburb of dwellings, community, and housing complexity environmental assesment, 4. Each category of influence ratio was extracted to assess total deterioration throughout the expert question survey. 5. Each category analysed (1) $0{\sim}30%$: function is good (unnecessary to improve) (2) $31{\sim}40%$: average (necessary of partial improvement) (3) $41{\sim}59%$: bad (necessary of total improvement) (4) $60{\sim}100%$: the worst (unable to improve throughout the repair)

In this study, 15 evaluation questions about light were developed and presented to 30 middle school students, and then the theory of knowledge space was used to analyze the status of the middle school students' knowledge about light. Not only was the state of the students' knowledge about light intended to be measured by schematizing the knowledge hierarchy obtained; the data obtained were also intended to be used as basic materials to improve the teaching methods used. To achieve the purpose of this study, the evaluation results, the individual knowledge state, and the hierarchy of questions were analyzed. As a result, different knowledge structures were found in the individuals and groups, and it was determined that individuals and groups should be diagnosed differently. In addition, the implication that there is a connection between each question and the individual knowledge state was drawn.

The goal of the information system in tourism, like that of general information systems, is to create users' information needs so that the users continuously revisit the information system and retrieve the information on a regular basis. However, unlike any other information systems, the primary objective of the tourism information system is to attract tourists to the tourist sites rather than to create the users' needs for their future revisits to the information system. The tourism information system is therefore more closely related to tourists' overall tourism destination image towards the tourism destination. In this respect, the evaluation of the tourism information system should be based on tourists' overall tourism destination image towards the sites. This study examines how tourists' overall tourism destination image towards the sites affect the evaluation of the tourism information system. Specifically, I employ the tourism information system provided by Sokcho and Delone and Mclean(2003)'s the Information System Success Model in order to investigate this research question.

This paper is about the use of existing evaluation methods, which evaluate learning determined by the score of an exam, which is either a multiple-choice type or single choice type question. These scores don't show the objective evaluations that cause some negative opinions about the scores. In this paper, we propose that the evaluation of the methods of self-directed learning use the triangle-type function of the fuzzy theory so that the learner can objectively evaluate their own learning ability. The proposed method classifies the result of learning into three fuzzy grades to calculate membership, and evaluate the result of an exam according to the final fuzzy grade degree as applied to the fuzzy grade sheets.

It is not efficient and scarcely out of the question to use commercial expensive electron beam lithography system widely used for semiconductor fabrication process for the manufacturing application field of various devices in the small business scope. Then scanning electron microscope based electron beam machining system is maybe regarded as a powerful model can be used for it simply. To get a complete suite of thus proper system, proper chamber with high vacuum condition is necessarily required more than anything else to modify scanning electron microscope. In this study, special chamber unit using rotary pump and diffusion pump to obtain high vacuum degree was designed and manufactured and various evaluation tests fur recognize the vacuum characteristic were accomplished.

This study empirically analyzes the economic validity of rape farmers. The analysis of economic evaluation is based on the benefit-cost analysis. Previous studies have undoubtedly expanded our understanding of the importance of substitution effects on a rapeseed for bio-fuels. However, earlier studies have mostly dealt with the concept of biodiesel's economics analysis, but this paper's attentions have been paid to the economic analysis of farm. The aim of this paper is suggesting the most appropriate policy brings about why farmhouses should cultivate the rape. To answer this question, this paper adopts a scenario analysis and the B/C ratio is used.

The students' feedback is important to measure and improve teaching performance. Many teacher performance evaluation systems are based on responses to closed question, but the free text answers can contain useful information which had to be explored. In this paper we present a lexicon-based sentiment analysis to explore students' text feedback. The data was collected from a system for the evaluation of teachers by students developed and used in our university. The students comments are in Romanian language so we built a Romanian sentiment word lexicon. We used this to categorize the feeback text as positive, negative or neutral. In addition, we added a new polarity - indifferent - in order to categorize blank and "I don't answer" responses.

The necessity of an empirical study on how projection mapping videos are evaluated from consumers' point of view has arisen, as they can lead to visual pollution if factors including spatial characteristics around the structure and details of the contents are not taken into consideration. This study aims to evaluate projection mapping videos and elucidate the question on whether evaluation criteria positively influence the satisfaction level or not. Above all, five evaluation criteria including artistry, creativity, identity, immersion and usefulness were deducted and a hypothesis from preceding research "each evaluation criteria will positively(+) influence the satisfaction level of projection mapping video" has been established. In order to test the hypothesis, big domestic department stores which screened projection mapping videos were selected and a verification experiment has been conducted with ordinary citizens as subjects. In the result of the experiment, among the five evaluation criteria, artistry, creativity, and usefulness were chosen, while identity and immersion were dismissed. The result verifies that if useful information is provided in forms of interesting contents produced with distinctive ideas and creative methods, it will satisfy the consumers as attractive public design.

This study investigated student's prior conceptions and evidence evaluation about Light and shadow. One hundred twenty six students were given Explanation-after-choice type Questions to investigate student' prior conceptions and Choicd type Question to identify student's idea about scientific method and characteristics od observation. Forty-four of the 126 students were interviewed to explore student's evidence evaluation. Eighty students (63.5%) thought that the shape of material affected the shape of shadow but the shape of light source did not Only 58.8 precents of all responses were evidence-based responses. Characteristics of evidence affected student's evidence evaluation : student made evidence-based responsed to the accord evidence more frequently than discord evidence. Among evidence-based response to the discord evidence. 35.5% of responses were the case that student felt cognitive conflict or explored other variables by recognizing discord between his/her own ideas and evidence or distort the evidence. Student's idea about characteristics of observation did not affect the evidence evaluation, but student's idea about scientific method affected the evidence evaluation.
