  • 경간이 길어지고 강성이 유연한 바닥판 구조물은 처짐과 진동에 같은 사용성에 있어서 많은 문제점을 가지고 있다. 따라서 다양한 진동제어 시스템이 제공되고 있으며 TMD와 같은 수동제어 시스템은 적용에 있어서 한계가 있다. 본 논문에서는 MR감쇠기와 TMD를 조합한 준능동 TMD의 제어기법에 따른 제어성능을 알아보았다. 준능동 TMD의 감쇠기를 Groundhook 모델로 모형화한 경우에 주구조물인 바닥판 구조물의 진동제어에 있어서 보다 효과적인 것을 볼 수 있으나 TMD의 변위를 제어해야 하는 경우에 준능동 TMD의 감쇠기를 Skyhook 모델로 모형화하여 진동을 제어할 필요가 있다. 그리고 바닥판 구조물과 TMD를 동시에 제어해야하는 경우에는 Hybrid 제어기법이 우수한 제어성능을 보이고 있다.

  • The purpose of this study was to find out the source of information and clothing benefits of female university students according to their shopping orientations. 340 female students living in Seoul were surveyed and the following results were found: Female students were divided into recreational shoppers and convenience shoppers according to their shopping orientations. Recreational shoppers exhibited interest in self-improvement, individuality, economy, and convenience shoppers in practicality of clothing benefits. Recreational shoppers focused higher value on gathering information than convenience shoppers and prefer information they gain in store display and mass communication media. Recreational shoppers have higher value on self-actualizing than social affiliation value. The findings indicate that shopping orientation can be used effectively to segment the female university students market and the finding of this study contribute to the development of strategies for clothing producer or retailer to provide a strong means to satisfy their shoppers' needs.

  • Anaplastic large cell lymphoma(ALCL) is an uncommon type of non-Hodgkin's lymphoma(NHL) populated with anaplastic, often bizarre cells that express CD30 (Ki-1) antigen. The unusual histologic and cytologic features may cause confusion with other neoplasms, such as poorly differentiated carcinoma, melanoma, Hodgkin's disease, or true histiocytic lymphoma. Although the cytologic features of ALCL have been well described, there are few reports about cytologic findings of the sarcomatold variant of ALCL. We experienced a case of fine needle aspiration(FNA) cytologic findings of ALCL which mimicks malignant fibrous histiocytoma. FNA cytology of chest wall mass in a 62-year-old female with a history of peripheral T-cell lymphoma(Lennert lymphoma) revealed a heterogeneous population of single cells and poorly cohesive cells with large, pleomorphic nuclei and spindle cells gathering around vascular structures within an inflammatory background. Additional features of the neoplastic cells were eccentric, multilobated nuclei with occasional 'wreath-like' configuration; abundant cytoplasm with vacuolization; and prominent nucleoli. The cytologic features suggested sarcoma, especially malignant fibrous histiocytoma. The diagnosis was made retrospectively with an aid of immunocytochemical staining.

  • Individuals depend considerably on gathering information from personal social networks rather than from commercial network channels or the mass media. Most academic journals that have examined this topic concentrate on online users' information-searching behaviours; however, this paper discusses online users' information-providing behaviour in the online community. The aim of this study is to investigate that online users' motivation to write reviews on Facebook and how the motivations affect users' information-providing behaviour. This study focusses on Facebook members' motivations that affect their review-writing behaviour. The fundamental theory for examining this topic is Vogt and Fesenmaier's (1998) 'information need'. This study modifies Vogt and Fesenmaier's (1998) theory for virtual communities through the development of each concept's measurement items, selecting the information need of four variables: functional, hedonic, innovation, and sign need. Among the four variables, sign need is the most important factor for Facebook users in the virtual environment. Through sign need, people indicate their status, personality form, and position, which significantly affects members' review-writing behaviour on Facebook.

  • This study is planned to gather necessary data for setting up a system on students' health care in the university. In order to obtain statistical data on the students' health care problems especially in 'depression' among the mental health problems of the students, 'The Beck Depression Inventory' by A. T. Beck and 'Zung's Self-Rating Depression Scale' by W. W. K. Zung were used for gathering numerical data of scale of depression. It is evident that we have to prepare for further medical examination and health care educations for several students. For these students, it is clear that they have problems not only in mental health but also in physical health. I have screened out the high scored students for comparison and analysis. And it disclosed that we have to build up a periodical and continuous 'Health Screening System' utilizing Health Questionnaire for both physical and mental aspects, which will bring up us the very exact result to pick out any person who has healthy problem among the enormous number of the students with handy, convenient and effective procedures but with the least expense and effort. Also it is my firm confidence that this system will be applicable for primary health care control of mass population in local community or any organization.

The parents acquired information about school-based comprehensive oral health care program; 58.7% by their children, 11.2% by mass-media, 10.0% by dentists and 3.7% by dental hygienists. 3. Most parents are in favor of school-based comprehensive oral health care program (96.7%). 4. Many parents(63.7%) prefer that social security law should budget for oral health care program. There were significant differences by sex(PE0.05) and age(PE0.01) As most parents are not so conscious of school-based comprehensive oral health care program, appropriate education program for dentists, dental hygienists and parents should be developed urgently.

Even in the present situation where any general criterion on eCRM dose not exist, utilization of eCRM is expected to be actively continued, which will cause many problems. In this regard, evaluating eCRM counts.
