Are the benefits derived from ICT based reference and information service worth the financial and other commitments devoted to it? In an attempt to answer this, this study delved into finding out the perceived benefits; the rational for ICT based reference services in Nigerian university libraries. The main objectives were to find out the purposes for using ICT facilities in reference services delivery and the perceived benefits derived from using ICT resources in reference and information services. Being a survey, questionnaire was used to collect data from the librarians of twelve (12) universities; two (2) each sampled from the six geopolitical zones of Nigeria. Data was analyzed using frequencies, mean scores and standard deviations. ANOVA statistical analysis was used to test the hypothesis of no significance difference in the benefits derived from ICT based reference services using p-value of 0.05 to calculate the level of significance. Findings showed that librarians and library users made use of ICT facilities for different reference purposes especially to obtain information they need using the internet. Other reference needs for which patrons used the ICT facilities included: - access to current e-books and e - journals, user education and access to global information in other libraries. Provision of current awareness services (CAS) and selective dissemination of information services (SDI), on-line searching using workstations in the library, provision of on-line public access catalogue (OPAC) services, keeping statistics of users of the reference section and compilation of bibliographies. Further findings showed that the librarians and library users derive a lot of benefits from their use of ICT facilities in reference services. The results showed that easy retrieval and dissemination of information to patrons were ranked highest by the librarians amongst others.

This paper investigates passengers' perceptions of the importance and satisfaction of airline service quality for improving the quality level of airline service. Importance-performance analysis(IPA) was utilized to analyze the gap between importance and performance of airline service qualify The result showed that passengers' perceptions of the importance and performance of airline service quality differed for Korean international air passengers. In particular, IPA analysis revealed that four attributes 'meal service', 'seating comfort', 'seat space and legroom', 'check-in service' were identified in the Concentrate Here quadrant-perceived to be important, yet perceived as being performed poorly. The airlines operating from/to the Republic of Korea should concentrate on the attributes included in this quadrant to improve the quality of airline service. On the basis of the IPA analysis, airlines should identify their strengths and weaknesses and draw up a plan to maximize their profits.

In this study, the optimal control method for minimizing of energy consumption for central cooling system with proper occupant comfort level is researched by simulation. The optimal control method is that the optimal set temperatures such as the condenser water temperature, supply air temperature, and chilled water temperature with environment variable change such as outdoor air dry-bulb and wet-bulb temperatures are obtained by suggested optimal control algorithm with maximum and part building load. The TRNSYS program is used for system modeling and the control performances with the suggested optimal control method are compared with the existing control method of fixed set points. The suggested optimal control method shows better responses in energy consumption in comparison with existing control ones.

Track maintenance works based on track geometry recordings are essential to enhance the safety and comfort of railway transportation. Usually, the track irregularity has been measured by a special inspection trains which all were imported from abroad. Because the inspection train speed is limited under 160 km/h, it takes a long time to inspect railways and there is difficulty in daytime operation. To solve this problem, we started to develop a track geometry measuring system (TGMS) with measurement speed up to 300 km/h which can be installed in commercial vehicles such as HEMU-430X. In this paper, we introduce a newly developed inertial TGMS and propose two inertial navigation system (INS) algorithms (method A, B) for measuring track geometry. In order to investigate advantage and disadvantage of each algorithm, we performed vibration test of the TGMS, which was simulated by 6-axis shaking table. Through the vibration test, we analyzed the influence of vehicle vibration on the TGMS which will be installed on bogie frame. To the vibration test, two methods satisfied the required accuracy of track geometry measurement under the level of the actual vehicle vibration of HEMU-430X train. Theoretically, method A is sensitive to vehicle vibration than method B. However, HEMU-430X's bogie vibration frequency range is out of interest range of measurement system. Therefore, method A can also apply the HEMU-430X train.

The purpose of this study was to analyze the brand preference, the clothing pursuit benefits, and the purchasing behavior of Chinese women. A survey questionnaire was distributed to Chinese women in their 20s and 30s. The surveys period was from 9th January 9th to $21^{st}$ February 2016. The respondents were 343 Chinese women living in Henan. The collected data was analyzed by frequency analysis, factor analysis, t-test, one-way analysis of variance, and Duncan's multiple range of verification. The key results of this study are herein summarized. The brands examined, listed in order of preference, are Ochirly, Only, Zara, Uniqlo, La Chapelle, H&M, Peace bird, Vero Moda, JNBY, and The Basic House. The five most preferred brands were then selected and further analyzed. For purchasing, the design and price were considered to be important, while for product evaluation, importance was given to the style, price, quality, and color. Factors important in the clothing pursuit benefits were found to be price pursuit, trend pursuit, brand pursuit, individual pursuit, comfort pursuit, and quality pursuit. Also, clothing pursuit benefits depends on the average monthly income, monthly clothing purchasing cost, and the education level of the individual. Lastly, we observed that the sources and store selection made noticeable difference in clothing pursuit benefits.

The purpose of this study is to help develop high quality brassieres with functionality and comfort, fitting adolescents' physical features during their growth period. This study conducts a comparative analysis of juvenile brassiere and adult brassiere to identify the problems of brassieres in the market. The raw data for this study was processed by SPSS 10.1. The results of this study are summarized as follows: 1. The results of this survey show that the girls' satisfaction of their breasts has correlations between breast protrusion degree and volume. The girls think that if they have protrusive breasts their breast volume is big, and their breast satisfaction level shows high. 2. The results show that the objective of brassiere wearing is to prevent breasts sag and rupture, make good breast shape, balance their entire body shape, and make beautiful outer garment line. Brassiere functions are to prevent jiggle of breasts, make a good body line, and cover the nipples. For the grader school students, they are wearing brassiere to make a good balanced body and as their breasts developed, they are wearing brassiere for beautiful body shape not just to cover up their breasts. 3. In regard to brassiere cup size recognition, as students have higher grade at school, they have better recognition abouxt their cup size. As they are better aware of their cup size, they have better satisfaction with their cup size. Therefore, choosing the right size of brassiere for their bust is very important. 4. Girl students' brassiere preference shows that 317 students (56.9%) prefer white for brassiere colors, following pink and flesh color. Their most preferred brassiere material is cotton (354 people, 63.6%) because cotton is not sensitive even for weak skin. For brassiere style, 273 students (49%) prefer round style, following spots and mold. Their most preferred brassiere style is stake. In addition, brassiere should not press their breasts because their breasts are developing during puberty period.

The use of emergency escape breathing devices (EEBD) is strongly required to protect against toxic gas or flooding caused by ship fires or accidents. Recently developed domestic EEBD products only satisfy the basic performance requirements, but no wear fit and activity performance evaluation has been done for real usage. In this study, the global level test requirements for wear comfort and activity of EEBDs were developed and the open and closed type of domestic EEBD products were evaluated. Poor visibility, longer wear time, breathing resistance, and hose obstruction in an open type and canister obstruction, weight unbalance, and an invisible black breathing bag in the closed type EEBD were estimated to be the main problems that need to be improved.

The aim of this study was to verify differences in autonomic responses that are affected by the configurations of one-room type units using an electrocardiogram (ECG). Accordingly, 43 one-room units that were collected randomly were classified into ten different types of floor plan configurations mainly according to the location of the bathroom and kitchen. An ECG was subsequently measured for each plan type and the average ratio of the LF/HF (Power in low frequency range/Power in high frequency range) was calculated to measure the comfort level of each space. The results revealed a significant statistical difference between the average LF/HF ratio between the plan types (p < 0.05) and provided compelling evidence suggesting that the configuration of the plan may affect the quality of one-room space. This approach appears to be effective in counteracting stress that may exacerbate psychological disorders in single person households.

This study is about the research of living environment in residential areas created by the land readjustment projects in the modern era, and recently lifted from Residential Environment Improvement district at the same time. The five criteria for evaluating the residential area are safety, health, convenience, comfort, and sustainability. The level of resident satisfaction in general is as follows. [completely dissatisfy as 5.30%, dissatisfy as 16.29%, neutral as 49.62%, satisfy as 16.29% and completely satisfy as 6.82%]. The results of the five survey items on the residential areas show that residents are aware of the area not as an old residential area to be demolished, but as a comparatively excellent residential area, namely very different results from the designation criteria of the redevelopment area designated by the Urban and Residential Environment Improvement Act. If the road conditions and the deterioration of the buildings are judged to be designated as the redevelopment area and to be removed these settlements, the residential areas with social sustainability could demolished. Based on this study, it is necessary to conduct the research to find out the reason for deriving the results of each evaluation item in the succeeding study. These studies are needed to rediscover, to develop and manage the value of many old residential areas scattered in the city centers of local areas.
