  • 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.

  • The purpose of this study is to develop a publicness evaluation index for indoor privately owned public spaces (POPS). In order to develop the index, 10 cases of indoor POPS in New York City were analyzed using Visibility Graph Analysis by evaluating its accessibility and visual openness. The results are as follows; (1) Accessibility and openness of indoor POPS were higher compared to other public spaces on the first floor. (2) Cases with high accessibility index installed a higher number of entrances. (3) Cases with high openness index were mostly composed of a glass wall. (4) The publicness index was high when the lobby and the indoor POPS are shared. (5) Atrium types were highly utilized and the evaluation index was also high whereas, linear types were less utilized and the evaluation index was lower.

  • 비정형 건축곡면의 패널분할 최적화 정도를 평가하기 위한 여러 가지 최적화 평가기법들이 개발되어 적용되고 있으나 이러한 평가기법과 평가지표들은 독립성, 보편성을 확보하고 있지 못하다. 그러므로 본 연구에서는 비정형곡면 패널분할 최적화 평가기법 및 평가지표에 관한 사례 및 선행연구 고찰을 통한 독립성 및 보편성이 확보되는 비정형 곡면 패널분할 최적화의 정량적 평가를 위한 평가항목 추출과 평가지표의 제안이 이루어진다. 제안된 세 가지 패널분할 최적화 평가항목은 원형 충실도, 생산 용이성, 연속성이며, 원형 충실도를 위한 평가지표로는 곡면 일치, 생산 용이성을 위한 평가지표로는 평면성, 평면 패널 비율, 연속성을 위한 평가지표로는 접선 연속성, 사이 간격이 제안되었으며 그 산출방법이 함께 제안되었다.

Especially, a laser type of profilemeter subjected to the longitudinal roughness index has been focused. The test result show that a new type of profile index, IRI(International roughness index) resulted from a laser type of profilometer was profitable for airport runway etc.. The present study provides useful results for the improvement of evaluation of the conventional profile index.

  • PURPOSE. The aim of this review was to analyze the evaluation criteria on mandibular implant overdentures through a systematic review and suggest standardized evaluation criteria. MATERIALS AND METHODS. A systematic literature search was conducted by PubMed search strategy and hand-searching of relevant journals from included studies considering inclusion and exclusion criteria. Randomized clinical trials (RCT) and clinical trial studies comparing attachment systems on mandibular implant overdentures until December, 2011 were selected. Twenty nine studies were finally selected and the data about evaluation methods were collected. RESULTS. Evaluation criteria could be classified into 4 groups (implant survival, peri-implant tissue evaluation, prosthetic evaluation, and patient satisfaction). Among 29 studies, 21 studies presented implant survival rate, while any studies reporting implant failure did not present cumulative implant survival rate. Seventeen studies evaluating peri-implant tissue status presented following items as evaluation criteria; marginal bone level (14), plaque Index (13), probing depth (8), bleeding index (8), attachment gingiva level (8), gingival index (6), amount of keratinized gingiva (1). Eighteen studies evaluating prosthetic maintenance and complication also presented following items as evaluation criteria; loose matrix (17), female detachment (15), denture fracture (15), denture relining (14), abutment fracture (14), abutment screw loosening (11), and occlusal adjustment (9). Atypical questionnaire (9), Visual analog scales (VAS) (4), and Oral Health Impact Profile (OHIP) (1) were used as the format of criteria to evaluate patients satisfaction in 14 studies. CONCLUSION. For evaluation of implant overdenture, it is necessary to include cumulative survival rate for implant evaluation. It is suggested that peri-implant tissue evaluation criteria include marginal bone level, plaque index, bleeding index, probing depth, and attached gingiva level. It is also suggested that prosthetic evaluation criteria include loose matrix, female detachment, denture fracture, denture relining, abutment fracture, abutment screw loosening, and occlusal adjustment. Finally standardized criteria like OHIP-EDENT or VAS are required for patient satisfaction.

  • This research This research aims at developing systemic evaluation model in terms of biotope preservation through reports, literatures, and expert survey analysis by implementing biotope structure analysis in area level with selecting Hyunpoong and Yuga-myeon, Dalseong county, Daegu metropolitan city as a site. First of all, as a result of biotope type classification of research site, biotope type groups are classified into total 13, and its biotope types are divided into total 61. Also, as a result of literature analysis, total 18 items are drawn such as diversity of biotope typical species as a index item to assess the preservation value of biotope, and the first evaluation index are divided into 10 and the second ones are divided into 8 according to characteristic of index items. As a result of expert survey analysis, All 10 index items, first evaluation index, show high importance average (above 4.7). As a result of implementation of main cause for categorizing evaluation index by characteristic, there are 3 factors such as 'obstructive factor.' Based on above survey analysis result, as a result of estimating the weight of each item, 'restoration factor' showed the highest, 3.4541, but 'factor of habitat stability' showed 3.1468, which is the lowest The systemic value evaluation was set by comprehensively analyzing these results. As a result of biotope preservation value evaluation through applying research site, total 19 types which are abundant in vegetation are classified into I class, 12 types in II class, 5 types in III class, 10 types in IV class, and 15 types in V class respectively. Lastly, as a result of second evaluation, it is analyzed that there are 17 special meaningful space to preserve species and biotope(1a, 1b) and 61 meaningful space to preserve species (2a, 2b, 2c).

  • This paper proposes method to find the subjective satisfaction index of an air-conditioner using consumer's sensory evaluation for an air-conditioner. A satisfaction index of an air-conditioner is presented the annoyance and freshness as ${\alphs}$, ${\beta}$ exponents of 1/f slope and is changed the annoyance and freshness as exponents of 1/f slope are changed. The satisfaction index of an air-conditioner is not improved if SPL is above the proper level although the 1/f slope has optimal ${\alpha}$, ${\beta}$ values. Therefore, this paper proposes the satisfaction index of an air-conditioner considered both SPL and ${\alpha}$, ${\beta}$ exponents of 1/f slope.

  • The purpose of this study is to identify the significant sound quality metric and compose the sound quality index of motor driven roller blind which is part of vehicle sunroof. Before subjective evaluation, sound characteristics of roller blind was analyzed and set the target operating sound for subjective evaluation. Thus, transfer sound of roller blind which has the characteristics of sound modulation was used for subjective evaluation. Linear regression was carried out by chosen Zwicker's metrics which are pointed by comments of jurors. Loudness and sharpness related metrics are prime metrics in sound quality index we composed. Effect of roller blind assay when it is attached to real vehicle was identified to evaluate the validity of index.
