  • Numerous foreign studies document perceived difference of the public toward male and female doctors, but little is known about the way Korean college students view the gender of the doctors. This study investigates whether or not college students evaluate the technical and socio-psychological skills differently depending on the gender of the doctors. This study also tests the association between the gender of respondents and the gender of doctors of their choice for several types of diseases. The 440 college students at one campus were selected using systematic stratified random sampling technique and were interviewed by questionnaire survey. Findings indicate that while the scores of technical skills are in favor of male doctors, the scores of socio-psychological skills are favorable to female doctors. We also find that there Is a statistically significant relationship between the gender of respondents and the gender of doctors of their choice.

  • The primary objectives of this research is to identify the unmarried mother's (1) socio-demographic characteristics and (2) factors that correlates their stress and (3) factors that predicts their stress. This study uses the data based on interviews with 136 unmarried mothers selected purposive sampling from the 5 unmarried mothers protective institutions in Seoul, Pyungtak, Chunchon, Taegu, and Gwanju. The major findings were as follows. First of all, the age of the first sexual activity of the late-teens among the unmarried mothers are over the half. The portions over the one time abortion are 33.3%. Second, the social support part in the coping sub-category had positive correlation with the stress of unmarried mothers. And the age of the first sexual activity and my thought on the adolescent sex had negative correlation with the stress of unmarried mothers. Third, the age of the first sexual activity predicted the stress of unmarried mothers. Therefore, the comprehensive and systematic intervention programs should be required to ensure that they intervene the stress of unmarried mothers.

  • Study was made for the work study application in industry by sampling one thousand manufacturing companies. Small and medium industries are far behind in systematic application of the work study technique. Large industries are gradually introducing the work study technique systematically in line with the nation-wide quality control movement. Major sessions that the industries feel important in IE curriculum were QC, Work study and Cost accounting followed by the Organization theory, Industrial psychology, and Labor relations. Most of the industries were still less aware of the sophisticated fields such as OR, SE and Simulation. They put more emphasis on QC and TQC and as a result, work study should be closely bounded to TQC in order to systemize the work study application in the future.

  • This study focuses on halal certification from the viewpoint of Malaysian restaurant managers. The increasing demand of halal food from the Muslim and non-Muslim consumers has given a good indicator to the hospitality industry to have the eating establishments halal certified. A sample of 643 restaurant managers has been selected throughout Malaysia using systematic sampling. Questionnaires were distributed using mail survey and data was then entered to SPSS version 21 for further analysis. It is gathered from the descriptive statistics that cleanliness during food preparation, meaning of halal and halal certification is important when dealing with food in a Malaysian restaurant setting. The results indicated that restaurant managers have high expectations toward halal certification. Furthermore, halal certification does generate some benefits beyond religion that contribute to Malaysia's positioning as a tourism destination and global halal hub.

  • With regard to the indolent clinical characteristics of prostate cancer (PCa), the more selective detection of clinically significant PCa (CSC) has been emphasized in its diagnosis and management. Magnetic resonance imaging (MRI) has advanced technically, and recent international cooperation has provided a standardized imaging and reporting system for prostate MRI. Accordingly, prostate MRI has recently been investigated and utilized as a triage tool before biopsy to guide tissue sampling to increase the detection rate of CSC beyond the staging tool for patients in whom PCa was already confirmed on conventional systematic biopsy. Radiologists must understand the current paradigm shift for better PCa diagnosis and management. This article reviewed the recent literature, demonstrating the diagnostic value of pre-biopsy prostate MRI with targeted biopsy and discussed unsolved issues regarding the paradigm shift in the diagnosis of PCa.

  • 사회봉사명령은 우리나라 보호관찰프로그램 가운데 가장 큰 몫을 담당하고 있는 만큼 사회적 기대 또한 매우 높다. 그러나 일반적인 자원봉사활동과 혼동될 정도로 그 프로그램 운영에 문제가 제기되고 있기 때문에 이 연구에서는 사회봉사명령 프로그램의 '교정'효과를 극대화시킬 수 있는 효과적인 운영 및 정착방안을 모색하고자 한다. 이러한 목적을 위해서 미국 미네소타주 교정국에서 지난 15년간 실시해 오고 있으며 매우 성공적으로 평가되고 있는 'Sentencing to Service' 프로그램을 방문하여 관련 행정, 실무책임자, 사회봉사그룹책임자, 사회봉사대상자들과의 면접 및 설문조사를 실시하였다. 표집방법으로는 체계적 표집(systematic sampling)을 사용하였다. 연구결과 사회봉사명령 프로그램은 그 교정효과 면에서 매우 고무적으로 나타났으며, 이를 위해서는 사회봉사대상자들의 자발적 참여동기를 극대화하고 지역사회로부터 적극적인 협조가 필수적이다. 특히 사회봉사그룹책임자의 자질이 매우 중요한 것으로 나타났다. 이와 같은 연구결과를 토대로 사회봉사명령의 관련자들을 위한 지침사항(guidelines)이 필요하다는 것과, 사회봉사그룹 책임자를 위한 교육 및 훈련이 중요하고 요구되는 자격요건으로 보아 사회복지사가 사회봉사그룹책임자로 채용된다면 프로그램의 효과를 극대화시킬 수 있다는 것, 정부가 사회봉사를 위탁받은 기관에 일정한 재정을 지원하는 것은 합리적이고 당연하다는 것, 마지막으로 사회봉사명령 프로그램이 구금형 대신에 부과됨으로써 법망의 확대(widening the net)효과를 초래하지 말아야 한다는 시사점이 있음을 발견할 수 있다.

  • This study was carried out in degraded and non-degraded community forests (CF) in the Terai region of Kanchanpur district, Nepal. A total of 63 concentric sample plots each of 500 ㎡ was laid in the inventory for estimating above and below-ground biomass of forests by using systematic random sampling with a sampling intensity of 0.5%. Mallotus philippinensis and Shorea robusta were the most dominant species in degraded and non-degraded CF accounting Importance Value Index (I.V.I) of 97.16 and 178.49, respectively. Above-ground tree biomass carbon in degraded and non-degraded community forests was 74.64±16.34 t ha-1 and 163.12±20.23 t ha-1, respectively. Soil carbon sequestration in degraded and non-degraded community forests was 42.55±3.10 t ha-1 and 54.21±3.59 t ha-1, respectively. Hence, the estimated total carbon stock was 152.68±22.95 t ha-1 and 301.08±27.07 t ha-1 in degraded and non-degraded community forests, respectively. It was found that the carbon sequestration in the non-degraded community forest was 1.97 times higher than in the degraded community forest. CO2 equivalent in degraded and non-degraded community forests was 553 t ha-1 and 1105 t ha-1, respectively. Statistical analysis showed a significant difference between degraded and non-degraded community forests in terms of its total biomass and carbon sequestration potential (p<0.05). Studies indicate that the community forest has huge potential and can reward economic benefits from carbon trading to benefit from the REDD+/CDM mechanism by promoting the sustainable conservation of community forests.

  • This paper reviews studies on information searching behavior in process control systems and discusses some implications learned from previous studies for use in human factors studies on nuclear power plants (NPPs) main control rooms (MCRs). Information searching behavior in NPPs depends on expectancy, value, salience, and effort. The first quantitative scanning model developed by Senders for instrument panel monitoring considered bandwidth (change rate) of instruments as a determining factor in scanning behavior. Senders' model was subsequently elaborated by other researchers to account for value in addition to bandwidth. There is also another type of model based on the operator's situation awareness (SA) which has been developed for NPP application. In these SA-based models, situation-event relations or rules on system dynamics are considered the most significant factor forming expectancy. From the review of previous studies it is recommended that, for NPP application, (1) a set of symptomatic information sources including both changed and unchanged symptoms should be considered along with bandwidth as determining factors governing information searching (or visual sampling) behavior; (2) both data-driven monitoring and knowledge-driven monitoring should be considered and balanced in a systematic way; (3) sound models describing mechanisms of cognitive activities during information searching tasks should be developed so as to bridge studies on information searching behavior and design improvement in HMI; (4) the attention-situation awareness (A-SA) modeling approach should be recognized as a promising approach to be examined further; and (5) information displays should be expected to have totally different characteristics in advanced control rooms. Hence much attention should be devoted to information searching behavior including human-machine interface (HMI) design and human cognitive processes.
