We report the electrocution of Korean native cattle by a fallen electric wire, which caused the death of thirteen animals. The owner of the cattle felt an electric shock on touching the steel pen and found a fallen 220-V wire on the roof of the barn; additionally, the roof was singed. Clinically, the animals developed spasm, difficulty breathing, and excessive salivation. Histopathologically, many visceral organs revealed severe congestion or hemorrhage, which is consistent with previous reports. This study revealed that the proper installation of electric wires on farms is essential to prevent economic loss by electrocution.

The background of appearing MMS is to cope with the difficulty that occurred in constructing CIM with multi-vendor production devices such as CNC, PLC and robot. But so far the popularized use of MMS service in machine shop is not generalized because of economical and environmental reason. In this paper to solve this problem the CNC_VMD gateway for 3 types of heterogeneous machine tools in which MMS support is not available is developed and its performance is evaluated in shop floor having CIM environment. The developed VMD has the functions such as MMS service, driver for CNC interface and supporting for network. Non-MMS compatible machine tool can be MMS-compatible by using the developed gateway with CNC_VMD.

The extranodal nasal NK/T-cell lymphoma was formerly known as lethal midline granuloma due to its most common clinical pattern like a destructive midline facial tumor. It often spread to other extranodal sites, such as skin, soft tissue, testis, upper respiratory tract, and gastrointestinal tract etc. For this reason, the term of extranodal NK/T-cell lymphoma, nasal type is preferred. Its disease entity may have a prominent admixture of inflammatory cells and necrotic tissues, further causing difficulty in diagnosis. A 44-year-old man was visited to our clinic with complaints of dysphagia and odynophagia during six months. He underwent three times punch biopsies and then, two times incisional biopsies. Finally, He was diagnosed as extranodal NK/T-cell lymphoma, nasal type involving oropharynx and supraglottis. We report an extremely rare case of extranodal NK/T-cell lymphoma, nasal type occurred in oropharynx and supraglottis with a brief review of literature.

The purpose of this study is to report a case of cost analysis for community-based social service centers for the disabled. This study analyzed 2002 accounting reports and annual business reports from 20 social service centers for the disabled. To identify weight of each service researchers surveyed each service in terms of significance, difficulty, and emphasis from managers among centers. For cost analysis, this study used TCA(Traditional cost accounting), rather than ABC(Activity-based costing) because of costs, time, and difficulty to find cost drivers. Findings indicate that average annual expenditure is about 1260 million Won. About 65.8% is for labor and another 13.2% is for programs. In addition, the cost for respite care service(1 hour basis) is 26,922 Won and job counselling with job capacity evaluation(2 hour basis) is 143,355 Won. These costs does not count on real estate costs and low labor costs. Thus, market price of those services should be higher than the above. This study analyzed the costs with service bassis rather than costing item basis. This method would provide more useful information to decision makers in relation to program expansion, reducement, and resources allocation etc.

Purpose: This study aimed to determine the correlation between job performance difficulties and job satisfaction that novice health teachers experienced in a new school environment, and provide the basic data necessary for policy development. Methods: Data were collected from 196 novice health teachers without in-service training program for the qualification of 1st grade and with less than four years of work experience in Korea. The self-report questionnaire consisted of general characteristics, perception of difficulties in job performance, and job satisfaction. The data were analyzed using the x² test, t-test, ANOVA, and Pearson's correlation coefficient. Results: Novice health teachers had the most difficulty in health education during their job performance, whereas teachers without hospital clinical experience encountered difficulties in health management. Those with less than two years of teaching experience or no experience of being contract health teachers had higher job performance difficulties. The results revealed that the lack of experience in performance at a school site had a considerable influence on the difficulty in job performance. In terms of job satisfaction, novice health teachers had the highest satisfaction with status recognition and the lowest satisfaction with their tasks in charge. Additionally, as the difficulty in job performance increased, job satisfaction decreased. Conclusion: The study results indicated the need for training to provide novice health teachers with sufficient experience in job performance before being placed in a school. The provision of support to respond to difficulties in job performance will improve job satisfaction and contribute not only to the development of novice health teachers, but also to the improvement of the quality of school health.

Objectives : The objective of this report is to identify the utilization of hospital school service during hospitalization among patients in their childhood and adolescence with psychiatric disorders. Methods : We retrospectively reviewed the medical record of child and adolescent psychiatric who were hospitalized during March 2009 through October 2012. We compared the one-year successful schooling and outpatient follow up rate between users and nonusers of the inpatient hospital school service. The hospital schooling experiences of the users were investigated upon follow-up visits to the outpatient clinic. Results : Sixty-three students received hospital school service during hospitalization among total 122 child and adolescent inpatients. Hospital school participants showed a significantly higher school reentry rate (61.9%) than non-participants (40.7%). However, there was no difference on follow up rate between the two groups. More than 60% of the 22 interviewed participants expressed an above-average level of satisfaction about hospital school service. Conclusion : Many patients with mental illness experience difficulty in receiving school education during treatment. That induces deterioration in disease, academic failure, poor social skills, low self-esteem, economic difficulties, and future job opportunities. The results of this study emphasize the importance of hospital school service and offer useful guidance for hospital school operation.

The purpose of this study is to discover and develop any implications which may arise in relation to science teachers' professional growth and development by investigating the difficulties experienced by elementary school teachers in science classes. 196 elementary school teachers were requested to write an anecdotal report regarding their science lessons. 30 science teachers in middle school also answered the same questionnaire. By means of inductive categorical analyzing, the difficulties were grouped into several categories. The results were as follows: (1) The difficulties elementary teachers experience in their science lessons fall into three categories; 'professional science knowledge(9.8%)', 'science laboratory activities(78.3%)', 'teaching methodology(11.2%)'. (2) Science teachers in middle school experienced similar difficulties. However, distribution differed from that of elementary school teachers; 'professional science knowledge(39.0%)', 'science laboratory activities(35.6%)', 'teaching methodology(27.1%)'. (3) The causes of these difficulties were identified as follows; a lack of time to prepare for science classes, insufficient substantial pre-service teacher education, and a lack of adaptive support to elementary school teachers.

KSNPs(Korea Standard Nuclear Power Plant) have been applied the break exclusion criteria to the high energy lines passing through containment penetration area to ensure that piping failures would not cause the loss of containment isolation function, and to reduce the resulting dynamic effects. Systems with the criteria are the Main Steam system, Feed Water system, Steam Generator Blowdown system, and Chemical & Volume Control system. In accordance with FSAR(Final Safety Analysis Report), a 100% volumetric examination by augmented in-service inspection of all pipe welds appled the break exclusion criteria is required for the break exclusion application piping. However, it is difficult to fully satisfy the requirements of inspection because 12", 8" and 6" weldolet weldments of Main Steam pipe line have complex structural shapes. To resolve the difficulty on the application of conventional UT(Ultrasonic Testing) technique, realistic mock-ups and UT calibration blocks were made. Simulations of conventional UT were performed utilizing CIVA, a commercial NDE(Nondestructive Examination) simulation software. Phased array UT experiments were performed through mock-up including artificial notch type flaws. A phased array UT technique is finally developed to improve the reliability of ultrasonic test at main steam line pipe to 12", 8" and 6" branch connection weld.

Low birth rate problem in Korea has been mainly derived from the increasing number of female employment and the change of consciousness of female. According to the recent report, some other causes of low birth rate are from the difficulty of using childcare facilities with quality services and the relative lack of quantities of the facilities. The basic principle of childcare includes protection, education, nutrition, safety, service to parents, and correlation with community. Childcare has been deemed to be the social system even to guarantee the parents' right of work. Even though a lot of progress has been made in childcare facilities by changes for a long period of time, the research on the actual condition shows that there are relatively little changes of the space organization of the childcare facilities reflecting characteristics of community and developmental characteristics of infants and children. Now a days it has been appeared as a social problem that childcare has to be needed as a part of systematic education program for such an important infant era.
