This study examine the selection criteria for recruiting social workers, commonly agreed by the persons in charge of human resources. We visited 46 social welfare facilities and performed interviews individually with them. Thirty three items belong to 7 different areas (ability, career, suitability and agreement to the facility, characteristics, recommendation, religion) were made based on the results of interviews, and these items were sent to social welfare facilities in 16 different cities in Korea for asking questions (from Oct, 2012 to Apr, 2013). One hundred and sixty cases were collected and among them 45 cases exhibiting consistency rate less than 0.2 were finally selected. Superior scope and subordinate scope were extracted and comparisons between day care centers and living institutions were made. Results demonstrated that ability of social workers was the most important for superior scope and suitability and agreement of social workers to both day care centers and living institutions were the most important factor for recruiting workers.

In this paper, the performance of Hybrid CDU MFSK system has been analyzed in the environment that narrowband Class-A impulsive noise include Gaussian noise in wireless communication channel and Nakagami fading. The performance of system improved to adopting both of technique MRC diversity and BCH channel coding. The results show that there is substantial degraded in Hybrid CDMA system performance by impulse index is stronger and the fading index is smaller. But also improvement can be obtained when BCH coding techniques are adopted. Additional MRC diversity techniques is more improvement than BCH coding techniques when degraded environment with the low fading index. But BCH coding techniques is more improvement than MRC diversity techniques when fading index has been increased. The Hybrid CDMA MFSK system is incomplete to voice communication standard BER$(10^{-3})$ in Rayleigh fading by independent each adopting techniques BCH coding and MRC diversity. But it's satisfy(improvement can be obtained) to voice communication standard BER in strong impulse noise(24dB over) by adopting techniques BCH coding and MRC diversity at a time. Additional it's a substantial enhancement $(10^{-3})$satisfaction) in fading index (m=3, 22dB) in addition to strong impulse noise and 24dB over with data service standard $(10^{-5})$ BER satisfaction. This result show that there is error performance improved by diversity branch and coding advantage.

Objective : This study aims to identify the job market for occupational therapists by analyzing recruitment advertisements for occupational therapists from 2011 to 2018. Methods : A total of 15,869 job placement notices posted on the portal site(http://otbrain.com/) were collected to analyze the job market for occupational therapists based on their regions, employment types, salary levels, employment times, and recruitment fields. Results : The total number of annual recruitment advertisements for occupational therapists was 544 which was higher than the number of people who passed the national exam. According to the region, recruitments were concentrated in the Seoul and Gyeonggi Province. According to employment type, the employment rate of permanent workers was on the decline but that of temporary workers showed an increasing trend. The salary level was the highest with the annual salary ranging from 20 million won to 25 million won or less, and the recruitment fields were found to have about 4.6 times more offerings in the adult and senior fields than in the pediatric fields. Conclusion : These study results can be used as a basic data for identifying the job market for occupational therapists.

This study started from the question of whether the preference of corporate recruitment can be achieved without any difference between the start-up experiencer and the general job seekers. Therefore, the purpose of the study is to identify the factors related to start-ups that affect the preference of job seekers for companies, and to analyze the differences in the factors related to start-ups between general job seekers and job seekers with start-up experience. Third, it is to see the difference in the preference for employment between job seekers with start-up experiences and general job seekers. The independent variables of the research model were entrepreneurship, motivation for start-up (job search), and characteristics of the job seekers (founder). The dependent variables were job preference, and the moderating variables were presented as job seekers' classification (job seekers with start-up experience vs. general job seekers). The subjects of the study were personnel managers of 100 companies with more than 5 years of establishment and 100 new companies with less than 5 years of establishment. The questionnaire was distributed in two types, and 189 respondents, including 101 job seekers with start-up experiences and 88 general job seekers, were finally used for analysis. The results of the study were as follows. First, as a result of multiple regression analysis on both experienced start-up experiencers and general job seekers, only entrepreneurship had an effect on preference for recruitment. Second, the moderating effect of job seekers' classification was found only in the relationship between motivation for start-up and preference for employment. Third, the result of multiple regression analysis based on the start-up experiencers showed that the relationship between the motivation for start-up, the preference for recruitment, the characteristics of founders and the preference for recruitment was statistically significant. On the other hand, the characteristics of the founder and the preference for employment were rejected. Fourth, the results of the study based on general job seekers showed that the motivation for job search decreased the preference for employment. The study did not provide the results of differences in recognition between different industries, traditional enterprises and venture businesses due to the limitation of small examples. There is no clear definition of start-up experiencers either. However, it is meaningful to suggest the implications of what preparations should be made when the start-up experiencers close their start-ups and turn their career into employment and to help them to accurately recognize the importance of entrepreneurship. It also provides the preference of the general job seekers for the company, the preparation for successful employment, and the implications for the direction of the future start-up revitalization.

This study put the purpose to contribute in the way of complementing a qualification of the opened examination for the fire service to improvement of disposition and specialty of a firemen, and to development of a fire department. The subjects of the opened examination for the fire service are mostly same as those of general civil service examination, and they incite indiscreet competition. As a result, firemen morale became declining. On the basis of every kind of documents and data and the analysis of a questionnaire with students of the department of fire safety supervision, we should solve the problems of lack of qualification and professionality causing stress from work by the unit completion system, which qualifies those who complete prescribed unit in the opened examination for the fire service. It must promote the specialty of a fire fighter so that we can step up to the advanced fire department.

This paper describes the improvement of broadband radio channel characteristics using a MMSE adaptive equalization technique as a fundamental study of high transmission rates in indoor radio channel. First, the performance of 16-QAM system that employs a MMSE linear adaptive equalizer in Rayleigh fading channel is analyzed. Next, in order to improve broadband radio channel characteristics, we apply an adaptive equalization technique employing the MMSE algorithm to the radio channel measured by using circularly polarized antenna under indoor NLOS(non-line-of sight) environment. Consequently, for 16-QAM with adaptive equalizer, we can achieve the improvement of about 13 dB at $10^{-3}$ error rate as compared with general 16-QAM. Moreover, it was found that the adaptive equalization technique could improve broadband radio channel characteristics over the all measured areas. Also, it was found that the employing both adaptive equalization and polarization diversity technique together could improve broadband radio channel characteristics and reduce fading more effectively.
