The Internet has become an increasingly important source for finding the right employees, so more and more companies post their job openings on the Web. The large amount and dynamic nature of career recruiting information causes information overload problems for job seekers. To assist Internet users in searching for the right job, a range of research and commercial systems were developed over the past 10 years. Surprisingly, the majority of existing job search systems support just one, rarely two ways of information access. In contrast, our work focused on exploring a value of comprehensive access to job information in a single system (i.e., a system which supports multiple ways). We designed Proactive, a recommendation system providing comprehensive and personalized information access. To assist the varied needs of users, Proactive has four information retrieval methods - a navigable list of jobs, keyword-based search, implicit preference-based recommendations, and explicit preference-based recommendations. This paper introduces the Proactive and reports the results of a study focusing on the experimental evaluation of these methods. The goal of the study was to assess whether all of the methods are necessary for users to find relevant jobs and to what extent different methods can meet different users' information requirements.

Pro-environmental life styles, foundations of a collective civilization and preservation of our tradition at rural communities hold a great public profit value, of which importance has been strongly emphasized during last decade. Here, the environmental color is one of the most influential elements that determine the image of the rural landscape. Whenever an alternative color element is introduced to rural town, it is very important to examine its effect on the existing environmental color. Typically, a preference-surveying method has been used to evaluate the suitability of such environmental color balance. However, we note that the reliability of this method is limited by the subjectivity of a respondent. And thus, it is highly desirable to develop a more objective method. We propose a feasibility study for using an aesthetic-measure to evaluate the environmental color of a rural town. In this work, we looked into the validity of our approach by comparing its result with that of the preference-based-method as a way to determine the environmental color. Our study is based on 20 photo images from Ansung-city Yangsung-myeon Donghang 2ri Kyo-dong town in Kyongki Province.

Science museum are dealing with exhibits on field of changing science and technology, and previous research suggested that exhibits replacement should carried out at least every 5 years. In order to efficiently replace exhibits within a limited budget, various studies analyzed visitors' preferences to exhibits. Recently, studies use various technologies to collect the data on visitors' preferences automatically, but almost of studies had a high dependency on their visitors such as visitors needed to carry specific sub-devices in the museums for gathering data. As complementing the limitations of previous research, this study introduces the improved method which is able to automatically collect and quantify visitors' preferences to exhibits using TensorFlow, a deep learning technology. By the proposed analysis method, it was possible to collect 2,520 data of visitors' experience on exhibits in totality. Based on collected data, attraction power and holding power indicating the preference of visitors on exhibits were able to be calculated. The result also confirmed antecedent research conclusion that the attraction power and holding power of the exhibit which consists of 3 dimensional structures work are higher than other exhibits. As a conclusion, the proposed method will provide more convenient data collection method for detecting visitors' preference.

교정시설 내 정신질환 수용자 수 급증에 대한 해결방안으로 다양한 전문 수용시설의 확충 방안이 제시되고 있지만, 관계자의 선호도에 관한 연구는 미진한 편이다. 따라서 본 연구는 정신질환 전문 수용시설에 대한 교도관의 선호도에 영향을 미치는 요인들을 탐색한다. 2019년 국내 교정기관 6곳에서 근무 중인 교도관들의 설문조사를 바탕으로, 정신질환 전문 교도소, 정신질환 전문 구치소, 정신질환 전문 수용동, 종합의료 교도소에 대한 교도관의 선호도와 다양한 변수들의 인과관계를 이항 로지스틱 회귀분석을 적용해서 분석하였다. 연구결과, 교도관들은 정신질환 전문 교도소 확충을 선호하는 것으로 나타났으며, 교도관 나이, 정신질환 수용자의 교정위반 행동, 치료 또는 약물 거부, 관련 법령 미비, 교도관의 정신질환센터 근무 경험이 정신질환 전문 교도소의 선호도를 높이는 요인으로 나타났다. 반면에 교도관 직급은 이런 선호도를 낮추는 것으로 증명되었다. 이를 통한 정책대안으로는 정신질환 전문수용시설 확충 과정에서 교정현장의 목소리 반영과 치료를 거부하는 정신질환 수용자들에 대한 법령의 마련을 제안한다. 후속연구에서는 보다 많은 교도관들의 특성 및 의견이 반영된 자료를 수집하여 다양한 변수들이 활용된 좀 더 분석적인 연구를 진행할 예정이다.

In order to examine theoretical underpinnings of preference for built forms, 129 subjects are asked to rate a series of 9 slides of residential houses depicting a wide range of architectural styles on a 5 point scale, for coherence, complexity, excitement, familiarity, and natural harmony, respectively. Based on Lee's (2002a, 2002b) two previous studies addressing the issue of aesthetic beauty evaluation for man-made creatures (e.g., residential housing scenes), this study summarizes several meaningful findings. As reported by all the subjects, first, both "desire to visit" and "desire to live in" turned out to be a good predictor of preference as the two measures are highly correlated in statistically significant levels (99.9%). People who desire to visit a spot are more likely to desire to live in it. Second, Pearson's correlations showed that coherence is the opposite end of complexity. The more likely a housing setting is hanging together, the less likely it looks to be complex. Overall, though, it is not clear that the two variables work directly in that way, as weighted on preference ratings. That is, coherence and complexity are likely to be totally two independent systems that affect the ratings of preference. Third, both excitement and environmental sensitivity (e.g., harmony of a house with its surrounding nature) most highly account for the preference for various housing scenes, while familiarity has only a little effect on preference ratings. Possibly, people like or dislike a visual thing, no matter how much they are familiar with it. Finally, this study suggested that design professionals could communicate effectively with their clients if sets of visual standards as an appropriate communication tool for better design are properly established.

This study was aimed at examining the determinants of organizational creativity at nursing care units of university hospitals. Using some items of the Creative Nursing Practice Index(CNPI), the Nursing Work Index-Revised(NWI-R), and the Work Preference Inventory(WPI), an empirical study was conducted with a sample of 543 nurses at 49 nursing care units in two university hospitals in Korea. Data collected from the individual respondents were aggregated and transformed into the secondary data at organizational level. The data were analyzed, using Pearson correlation and hierarchical multiple regression method. The results of the study showed that organizational creativity has positive relationships to task motivation, including enjoyment and challenge to work, and work environment supporting nurses' autonomy and collaboration. Task motivation of the units and autonomous work environment explained 16.3% and 7.9% respectively in the variance of the organizational creativity. Organizational creativity was found to be significantly influenced by challenge and autonomous environment. This result implies that nursing managers should make an efforts to enhance the organizational creativity of nursing units by motivating their staff to challenge to a novel way of doing at work and making the work environment more autonomous.

The survey was performed by questionnaires from July 13 to August 25, 1999 against 353 of males. As a general factor, the subjects of survey were male drivers in their forties to fifties. Their education level was middle school (46.5%) and high school (47.3%) diploma. The subjects were composed of 44.2% of city workers and 55.5% of suburban workers. This study showed that the city workers eat three meals per day with high percentage (92.9%) and a large number of suburban workers (21.3%) eat two meals only. Most of the subjects 782.% responded that their diet life were irregular due to the property of their job. The food preferences of most of workers (94.9%) were Korean food rather than any other foods. Frequency of eating-out was much higher in city drivers than in suburban drivers. They considered taste of food firstly and the prices of food secondly, but the nutritional value of food was considered with a very low percentage (14.7%). Their favorite menu turned out to be the Korean style one-dish food, of those one-dish Koran food, they preferred rice or soup to the noodles. These results suggest that he nutritional education against the workers at transportation business is needed to set the proper menu considering the characteristics of the preference each group of workers.

The ratio of old persons among the total population is rapidly increasing and the apartment has become to the representative housing type in Korea. This means that many old persons would live in multi-family houses. Therefore the study was intended to examine the preferred characteristics of interior space organization in multi-family house by the aged. The characteristics were the number and usage of bedroom, necessity and type of dress room, type of living room, arrangement of work centers in kitchen, LDK type, the number and layout of bathroom, and type of entrance and balcony. The subjects were 122 old persons who lived in multi-family houses in Ulsan. The individual interview was carried out for collecting the data. The results were as the followings; The characteristics of interior space organization in multi-family houses preferred by the elderly were three bedroom, two bathroom, DK or LDK type, open planned living room, L shape arrangement of kitchen work center, entrance connected directly to outdoor space such as elevator hall or corridor, and the balcony located in front of living room and at the back of small bedroom. Even thouth the average age of population has increased, many apartments still be planned and provided without consideration of old persons. This study would contribute to plan the multi-family houses for the elderly.
