It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.

Human activities are often affected by weather conditions. Automatic weather recognition is meaningful to traffic alerting, driving assistance, and intelligent traffic. With the boost of deep learning and AI, deep convolutional neural networks (CNN) are utilized to identify weather situations. In this paper, a three-channel convolutional neural network (3C-CNN) model is proposed on the basis of ResNet50.The model extracts global weather features from the whole image through the ResNet50 branch, and extracts the sky and ground features from the top and bottom regions by two CNN5 branches. Then the global features and the local features are merged by the Concat function. Finally, the weather image is classified by Softmax classifier and the identification result is output. In addition, a medium-scale dataset containing 6,185 outdoor weather images named WeatherDataset-6 is established. 3C-CNN is used to train and test both on the Two-class Weather Images and WeatherDataset-6. The experimental results show that 3C-CNN achieves best on both datasets, with the average recognition accuracy up to 94.35% and 95.81% respectively, which is superior to other classic convolutional neural networks such as AlexNet, VGG16, and ResNet50. It is prospected that our method can also work well for images taken at night with further improvement.

The purpose of this study was to establish a better operation plan for medical school student internship by gaining a deeper understanding of the student internship process. Toward this end, an investigation was carried out using in-depth interviews of students with experience as student internship at Catholic University of Daegu School of Medicine. Students who participated in the student internship program at Catholic University of Daegu School of Medicine took part in the clinic twice every two-week period for a total of four weeks as a member of the care team. The students performed several activities during their internships, including for example history taking, physical examinations, keeping medical records, simulation of writing prescriptions, clinical skills, patient education, night work, and rounds with the attending professor. In this study were analyzed the contents of a student internship, the difference in clerkship, the competence of the faculty, student participation attitudes and the overall effect of the internship on the students. It was found that the in-depth contents, passion of members including professors and students, especially the role of the professor, was more important component than the contents of the internship program or clinical training. The student-intern system was revealed to have the following positive characteristics: 1) education deeper than clerkship was performed through one-on-one faculty-student interaction, and 2) students' experience was broadened.

This paper presents a scheduling technique that reflects various constraints in remodeling project of inhabited condition. The remodeling project of inhabited condition is required more detailed planning and control due to claims by noise, vibration, dust, smells, limited lift capacity, and limited temporary stock area. Because of the constraints, complexity in scheduling is increased and earlier completion is required to reduce the possibility of safety and environment accidents. Especially, in case of inhabited condition, the scheduling should be linked day-time/night-time/weekend work. This paper proposes a structured scheduling technique to incorporate those constraints in remodeling of inhabited condition. This scheduling technique considers not only remodeling process but also dismantling, newly-construction, and residents movement. Process expression method using MS-Project also presented to keep connectivity with existing scheduling system.

Objective: The aim of this study is to provide a current knowledge of the multiple issues regarding motion effects on crew performance. Background: The motions of the ship may create motion sickness, nausea and vomit. Also, these motions also disturb the balance of crew members, increase the energy expenditure of crew for shipboard work, and result in increased levels of injury and fatigue. However, the motion effects of the ship on crew performance has not been thoroughly investigated. Method: Participants(N=10) were engaged in an experiment in 2 experimental environments(training ship and ship handling simulator) and 2 navigational conditions(day and night). The COP(Center of Pressure) data were recorded as an objective measure of postural balance control and the SSQ(Simulator Sickness Questionnaire) was used as a subjective measure of sickness. Results: The results showed that COP has a no significant difference based on experimental environments, but significant effect on SSQ. Conclusion: During the virtual simulator navigation, subjects showed significant SSQ level changes, which included decreased SSQ data. But, there is no significant difference of COP between training ship and ship handling simulator. Application: The results of this study could be applied to the next generation of ship design to decrease effect of motion at sea and to increase performance of ship crew.

Purpose: This study was to identify the extent of and the relationships among self-efficacy, spiritual well-being, and job stress in clinical nurses. Methods: The subjects were 201 clinical nurses from three different general hospitals in B city. Data were collected from May 26 to August 9, 2012 and analyzed by using descriptive statistics, independent t-test, One-way ANOVA, Sheff$\acute{e}$ test, and Partial correlation coefficients. Results: The mean scores of self-efficacy, spiritual well-being, and job stress were moderate, 3.50, 3.58, and 3.44 respectively. There were statistically significant relationships between marital status, influence of religion, the number of night shifts per month, motives for choosing nursing as a career, job satisfaction and self-efficacy. Spiritual well-being was found to be significantly related to all participants' general characteristics, and job stress was significantly related to marital status and type of religion. There was a significantly weak positive correlation between self-efficacy and spiritual well-being, and a weak negative correlation between self-efficacy and job stress. There was no significant correlation between job stress and spiritual well-being. Conclusion: This study suggests that effective strategies to foster spiritual well-being is needed to enhance clinical nurses' self-efficacy, which should equip clinical nurses to better deal with job stress in their work places.

The common-envelope process is a complicated phase in binary evolution. A lot of effort has been dedicated to study the common-envelope stage, but many questions related to this process are yet to be answered. If one member of the binary survives the common-envelope phase, the binary will emerge as a white dwarf accompanied by a low-mass main sequence star in close orbit, often referred as a post common-envelope binary (PCEB). SDSS J0745+2631 is among the list of newly found PCEBs from the Sloan Digital Sky Survey (SDSS). This star is proposed to be a strong eclipsing system candidate due to the ellipsoidal modulation in its light curve. In this work, we aim to confirm the eclipsing nature of SDSS J0745+2631 and to determine the stellar and orbital parameters using the software Binary Maker 3.0 (BM3.0). We detected the primary eclipse in the light curve of SDSS J0745+2631 in our follow-up observation from January 2014 using the ULTRASPEC instrument at the Thai National Observatory. The data obtained on 7th and 8th January 2014 in g filter show an evident drop in brightness during the eclipse of the white dwarf, but this eclipse is less prominent in the data taken on the next night using a clear filter. According to our preliminary model, we find that SDSS J0745+2631 hosts a rather hot white dwarf with an effective temperature of 11500K. The companion star is a red dwarf star with a temperature of 3800K and radius of 0.3100 $R_{\odot}$. The red dwarf star almost fills its Roche lobe, causing a large ellipsoidal modulation. The mass ratio of the binary given by the Binary Maker 3.0 (BM3.0) model is M2/M1 = 0.33.
