  • Six recycling plants have started operation for recycling scrap home appliances since the spring of 2000 in Taiwan. The performance of the plants has not yet been measured during the 18-month period. The performance measurement, however, can be looked in several aspects. Because of the nature of these recycling plants, at least three aspects, namely government (representing general public), appliance manufacturers and owners of the recycling plants themselves should be considered in the performance evaluation. This study proposes various performance indices categorized in four groups: profitability, recyclability, automation and environment. The indices are different from the productivity and cost measures that are used in conventional manufacturing plants. Performances of three existing plants in Taiwan are evaluated as illustrative examples to demonstrate the use of the proposed measures. The practical implications of the performance indices are also discussed.

  • This research is related to the evaluation of rural amenities. Since the UR negotiations, the wave of market liberalization has brought many difficulties to the rural areas. This paper serves to identify a number of important elements such as socialization, cultural and ecological resources and investigate the viability of rural areas. The purpose of this study is to evaluate rural amenities by evaluation indices and establish planning direction of amenities for rural areas. The data have been collected by methods of a field survey and a questionnaire survey. The evaluation indices have been defined as socialization, safety, amenity and convenience by several researches. Villages have been divided into two groups. Seven(Shimchon, Ibaek, Muan, Dokpyong-li, Imchin-li Hyangyang-li, Wonwol-li) have been newly constructed, six(baeksa, Mokmyon, yongho-li, shindyae-li, hwangdun·songgae) have been redeveloped. There are considerable differences in the degree of satisfaction between he two groups. The results are as follows: 1) socialization is very necessary for amenities in rural villages. Especially the values of the resident's interactions and management of the village are most important in the preparation of an amenity plan in rural areas. So the plans and establishment of public facilities are requisite for the residents community. 2) The convenience of rural public facility plans is necessary for the improvement of the farmers'living conditions. For planning the rural villages, special regards are paid to characteristics of the village, such as the former place of residence and occupations. 3) Newly constructed village should improve their socialization and the redeveloped types should try to get a better life for amenity and safety, The residents of the redeveloped types show relatively high degree of satisfaction with indices of resident community, living convenience facilities, and management of village. On the contrary, amenity and safety are good in newly constructed types. This study has taken into consideration the characteristics of rural villages. It makes a contribution to the redevelopment of rural villages and improves amenities in rural villages. It is recommended that more studies classify the resources of rural areas and measure amenities which are significant to city dwellers in the future.

  • The purpose of this study is to suggest an appropriate index for evaluating preferences of Web contents by examining the h-index and its variants. It focuses on how successfully each index represents relative user preference towards topical subjects. Based on data obtained from a popular IT blog (engadget.com), subject values of the h-index and its variants were calculated using 53 subject categories, article counts and the 'Likes' counts aggregated in each category. These values were compared through critical analysis of the indices and Spearman rank correlation analysis. A PFNet (Pathfinder Network) of subjects weighted by $h_T$ values was drawn and cluster analysis was conducted. Based on the four criteria suggested for the evaluation of Web contents, we concluded that the $h_T$-index is a relatively appropriate tool for the Web contents preference evaluation. The $h_T$-index was applied to visually represent the relative weight (topic preference by user 'Likes' count) for each subject category of the real online contents after suggesting the relative appropriateness of the $h_T$-index. Applying scientometric indicators to Web information could provide new insights into, and potential methods for, Web contents evaluation. In addition, information on the focus of users' attention would help online informants to plan more effective content strategies. The study tries to expand the application area of the h-type indices to non-academic online environments. The research procedure enables examination of the appropriateness of the index and highlights considerations for applying the indicators to Web contents.

  • 문화재 범죄로 인한 문화재의 소실과 도난과 훼손을 방지하는 노력이 필요하다. 그러므로 문화재 범죄예방환경을 평가하는 것은 매우 중요하다. 본 연구의 목적은 문화재의 범죄양상을 분석하고 범죄환경유형을 분류하여, 범죄예방환경설계 요소를 도출함으로써 범죄예방환경을 평가하는 지표를 제시하는 것이다. 본 연구를 통해서 도출된 결과는 4가지로 요약될 수 있다. 첫째, 문화재 CPTED에서 고려해야 할 범죄는 도난, 방화, 훼손, 침입이며, 야간에 발생할 수 있는 상황을 고려해야 할 것임을 밝혔다. 또한 이러한 범죄에 취약한 건조물 문화재 189개소에 대한 범죄예방환경을 분석하여 10개의 유형을 도출하였다. 둘째, 비문화재 CPTED에 적용되는 6가지 원리 중에서 '활동 증대', '유지 관리' 등은 문화재에 적용되지 않아도 될 것으로 판단되었다. 문화재 CPTED에서 적용되는 주요 원리가 '접근 통제', '감시 강화'인 것으로 밝혀졌다. 부가적으로 '입지조건'을 고려할 필요가 있을 것으로 판단된다. 셋째, 접근 통제는 문화재 영역에 따라 '내부 영역', '경계', '외부 영역', '주변 환경' 부문으로 구분되며 22개의 평가지표가 분류되었다. 감시 강화는 비문화재와 동일하게 '자연적 감시', '조직적 감시', '기계적 감시' 부문으로 구분되며 21개의 평가지표가 포함되었다. 넷째, 10개의 유형에 CPTED 부문을 적용하여 14개의 문화재 CPTED 환경을 분류하였으며, 각 환경별로 적합한 평가지표를 도출하였다. 서원 향교 관아 유형은 43개의 평가지표가 요구되지만, 성곽은 10여 개의 평가지표만 사용될 것으로 예상된다. 다섯째, 모든 평가지표를 사용해야 한다고 판단된 서원 향교 관아 유형에 해당되는 돈암서원에 대해 현장 적용 가능성을 검토하였다. 검토 결과 CPTED의 평가지표를 현장에서 적용할 수 있음이 검증되었다. 그러나 조명, CCTV, 침입센서 등에 대해서는 3차원적인 별도의 평가기법을 개발하여 적용할 필요성이 있는 것으로 밝혀졌다. 추후 연구에서 문화재 유형별로 면밀한 현장조사를 거쳐 평가지표를 보완할 필요가 있다. 본 연구는 기존에 시도되지 않았던 문화재 전반에 대한 범죄예방환경설계의 평가지표를 제시한 것에 그 의의가 있다.

  • 본 연구에서는 경북 봉화군을 대상으로 하여 지속가능한 토지이용을 위한 생태계정보를 추출하기 위하여 경관생태학적 방법에 의한 생태계의 종합적 건강성을 평가하였다. Landsat TM 위성영상을 가지고 봉화군에 대한 토지피복분류를 실시한 후, 산림지역에 대하여 경관지수를 적용하여 생태계 건강성에 대한 면별 비교평가를 실시하였으며, 그 결과를 정규식생지수(NDVI)와 비교하였다. 경관지수를 이용한 생태계 건강성 종합평가에서는 석포면, 재산면, 소천면이 가장 양호한 것으로 평가되어 지역의 생물종의 풍부도와 다양성이 높을 것으로 보여진다. 봉화읍은 10개 면 중에서 생태계 건강성이 가장 낮은 상태로 나타났다. 정규식생지수(NDVI)와 비교하였을 때, 재산면, 춘양면, 소천면의 수치가 가장 높고, 봉화읍의 수치가 가장 낮은 것으로 나와 춘양면을 제외한 결과는 생태계 건강성 종합평가와 비슷한 결과를 보여주었다. 앞으로 보다 많은 보완적인 연구가 필요하지만, 경관지수를 이용한 경관규모 생태계 평가기법은 지속가능한 토이지용과 관련한 생태계 정보를 제공할 수 있을 것으로 기대된다.

  • This study was conducted to suggest an assessment indices to evaluate the ecosystem services of the unique functions of wetlands as well as economic value provided by the village wetlands. The assessment indicators applied in this study were used by the RAM indices. The results of RAM assessment on the village wetlands in Cheonan city were analyzed by item and critical functions of the village wetland. They were derived by assessment indicators of ecosystem services, and the village wetland ecosystem were presented by Focus Group Interview (FGI). The 20 critical indices were selected from 52 different indices by analyzing the wetland function assessment items. 13 indicators excluding duplicate indexes by function, were selected as ecological service impact indicators. Finally, ecosystem services were evaluated by using AHP analysis to calculate the weight of each assessment indices and apply it to the 9 village wetlands. The results of this study confirmed that the functions of the village wetlands are compliant with the ecosystem services. Based on this assessment of the unique functions of wetlands, it will serve as a methodology for assessing ecosystem services. The study was also conducted on 49 wetlands in Cheonan. The detailed assessment of wetland ecosystem services based on the wetland ecosystem function proposed by this study, was further developed as a follow-up study. It suggested that the wetland areas should be compared and be used as a general standard. In addition to the assessment of the economic value of ecosystem services provided by the village wetlands, it would be useful to assess the unique features and convert them into value.

  • In Asia countries the productions of ship building and marine engines have been increasing, specially Japanese marine industries have worked hard after 1960s and Korean ones after 1980s. Recently the other countries, as Taiwan and China, have been working so that these hour Asian countries are occuping the high level of shared ratio of productions for gross tonnages and horse powers, which are 74 and 64[%] of the world ones ($8.6\times10$+6[GT], $8.6\times10$+6[PS]) in 1994. Korean industries had the highest shared ratio of production of tanker vessel and 2 stroke diesel engine as 45[%]($2.2\times10$+6[GT]) and 37[%]($1.0\times10$+6[PS]) which were more than those of Japan as 34 and 16[%] in 1989 respectively. Some marine databases and their network links among Asian countries are proposed due to the posibility of collection and analyses with their own specifications by the marine industries and operators as well as Japanese ship reliability investigation works(SRIW) like SRIC in Japan. During 1966 and 1996 16 times of SRIW in Japan have been carried out by ship reliability investigation group(SRIG) in Japan. There have been collected and evaluated a great number of field data of failures and maintenances($700\times10$+3[occ], $1.6\times10$+6[MH}) during running hours($13.4\times10$+6[Hrs]), from which many kinds of evaluation indices could be gotten as the three indices of occurring rate$\lambda$(52.2[occ/1000Hrs]), average man-hour mh(2.29[MH/occ]) and manning index MI(119[MH/1000Hrs]). An estimation example having the three indices$\lambda$, mh and MI were shown by the SRIC 1990 Data Base in Japan for the two kinds of fuel oil suppling subsystems which are dual fuel oil one(DFOS) and mono fuel oil one(MFOS). Three indices MI, and mh for DFOS and MFOS results in 7.16 and 5.20[MH/1000Hrs], 2.63 and 2.06[occ/1000 Hrs]. Therefore the more simple subsystem MFOS can save approximately 30[%] of maintenance load. Finlly an utilization methods are shown for the SRIC in Japan by means of computer system and worlwide internet links.

  • Purpose: The purpose of this study is to develop a measurement scale for evaluating the auditory affect of automobile engine sounds. Methods: In order to collect affective vocabulary, literature review, user tests, and expert interviews were conducted. Affective vocabulary related to automobile engine sounds was selected through three methods. To develop the evaluation scale, open/close card-sorting and expert interview-based survey method was used. Results: The results of this study are as follows; In order to select the main affective vocabulary from the collected vocabulary, 39 vocabularies with a frequency of 5 or higher were selected as vocabulary expressing the main auditory affect of automobile engine sounds. Each affective vocabulary is divided into three di- mensions, it was confirmed that the conceptual model for the auditory affect of automobile engine sounds is composed of three levels: intuitive, descriptive, and evaluative of hierarchical structure. As a result of the study, four indices of intuitive dimension, seven indices of descriptive dimension, and one index of evaluative dimension were derived from the evaluation scale of the auditory affect in an automobile engine sound. Conclusion: The auditory evaluation scale developed in this study can be used to systematically measure and evaluate the auditory affect of automobile engine sounds.

  • With the development of the American Customer satisfaction index (ACSI), research on customer satisfaction measurement or evaluation methods have become significant in the last decade. Most of international customer satisfaction barometers or indices are evolved based on the cause and effect relationship model of ACSI. Of critical importance to validity of customer satisfaction indices is how to construct a measurement attribute or indicator model and provide an effective implementation method effectively. Quality Function Deployment (QFD) is a very useful tool for translating the customer voice into product design through quality engineering. In fact, this is a methodology for measuring and analyzing evaluation indicators by their relationship matrix. In this paper, we will make an effort to integrate the framework of QFD into the measurement problem of customer satisfaction, and also develop a new multi-phase QFD model for evaluation of Customer Satisfaction Index (CSI). From the houses of quality in this model, the evaluation indicators impacting on customer's global satisfaction are identified by means of their relationship matrix. Then the evaluation indicator hierarchy and its measurement method for the customer satisfaction index are presented graphically. Furthermore, survey data from the Chinese automobile maintenance sector and a relevant case study are utilized to show the implementation method of the QFD model used to measure and analyze of customer satisfaction.
