This study is planned to investigate the compliance of small sized enterprises of under 5 employees directed by Industrial Safety and Health Act. Occupational safety regulation can be required for employer and employee to comply because that all members of workplace should be involved to protect worker's health. When all members of workplace comply with safety regulation, effectiveness of regulation will be realized as expectation. The study subject is composed of three groups as 501 employers, 501 employees of small sized enterprises of under 5 employees and 107 safety inspectors sampled by stratified random sampling for comparison. Data for analysis is collected from each sample using interview with structured questionnaires. Compliance is measured by 5 point scale composed by 8 sub items such as general perception, understanding, clearness, necessity, relevancy, implementation, penalty, and general compliance of the regulation. Among sub items of employer's compliance, the level of perception of regulation, necessity of regulation, relevancy of penalty are differentiated among three groups. The level of all 8 items of employee's compliance also differentiated among three groups. These results show that strategies for ensuring the same level of compliance among three groups will be needed through education, training and evaluation of regulation and feedback.

Purpose: To make new classification system of open fractures including the status of skin because of high rates of nonunion and complication in closed fractures with extensive skin damage. Materials and methods: One hundred-twelve one patients with fixation for open tibial fractures or closed tibial fractures with skin damage were included in this study from March 1991 to January 1997. The follow up period was at least 1 years. We classified the patients according to the Gustilo &Anderson classification, AO/ASIF classification and our new classification, and we compared the bony union time, bony union rate and complication rate among these classification. Result: The bony union time was 18.6 weeks in open fractures, 14.5 weeks in closed fractures with skin damage, and 18.1 weeks in combined new classification. The rate of bony union was 81% in open fractures, 83% in closed fractures with skin damage, and 77% in combined new classification. The complication was 40% in open fractures, 27% in closed fractures with skin damage, and 42% in combined new classification. There was close matched correlation in bony union time, bony union rate and complication rate among the Gustilo & Anderson classification, AO/ASIF classification, and our new classification. In closed fractures with skin damage above IC3, the rates of bony union and complication were similar with the open fractures above grade II. Conclusion: We propose simple new classification system of open fractures into 4 classes. The class I has minimal soft tissue damage and contamination with exposed wound less than 1cm or skin contussion, the class II has moderate soft tissue damage and contamination with exposed wound from 1 to 10cm or circumferential deglobing wound, the class III has severe soft tissue damage or contamination with exposed wound more than 10cm or extensive deglobing wound, and the class IV has class III injury with vascular involvement. And in the treatment of open fractures, we propose internal fixation in class I or II, and external fixation in class III or IV.

We evaluated the use of ultrasonography and arthrography in 15 patients, 16 cases with congenital dislocation of the hip from January 1995 to December 1996. All patients in this study was managed with following management program. Ultrasound study was performed as soon as possible after admission and applied continuous skin traction in modified Bryant's method until +2 station was achieved according to Gage and Winter's traction station. When this had been accomplished, arthrogram was performed and reduction was attempted under general anesthesia. Mannual closed reduction was tried at first and if failed, open reduction was attempted. K-wire fixation or capsulorrhaphy was occasionally performed in the unstable hip after reduction was acomplished and then the hip was immobilized in a bilateral hip spica cast. Inverted limbus was found in all cases at both ultrasonography and arthrography. Reduction was achieved by closed reduction in 6 cases, closed reduction with percutaneous K-wire fixation in 4 cases, open reduction with K-wire fixation in 2 cases and open reduction & capsulorrhaphy with K-wire fixation in 2 cases. The effect of prereduction traction was not evaluated in our study, but ultrasound study performed as soon as possible after admission was effective method for detection of the hip abnormality & making a management plan and arthrogram performed under general anesthesia was effective method for making a reduction plan.

A Study was done in order to collect suggestion for the improvement of special education in Korea. Through a questionaire given to the teachers and administrators in special schools and special classes, opinions and suggestions were collected concerning establishment and management of special education facilities. The subjects of this study were 351 teachers and principals with special classes and 809 teachers in 53 special schools, the number of which is the complete enumeration of them all over the country. The information was complied from October 15, 1979 to December 20,1979. According to the analysis of the data collected in this study, the following suggestions were made for the improvement of the special education in Korea. 1. The existing state of the special schools. 1) At present, the number of children receiving special education is 14,159 persons(special schools;8,052 persons, special classes: 6,107 persons), bur it only represents 4.59 percent of the total number of children requiring special education in Korea. 2) The number of subjects that are presently being taught in special education schools, who have obtained special education teaching certificates, were shown to be 72% of the male teachers and 79% of the women teachers. 3) It was shown that home environment and parents' school career for children in the special schools were at the low level. 2. The teaching viewpoint of the teachers at the special schools 1) The special teachers' general point of view on the special schools was comparatively reached to the positive level. 2) There was generally such a tendency as they gave much more consideration to the life centered education than to recovering the academic achievement on the exceptional children. 3) The level of the general teachers' attitude to the special schools and the degree of the understanding was generally about at the middle. 4) In this research, it was shown that the teachers' motive to take the special schools was comporatively to be willing. 5) It was shown that the evaluation and treatment for the special teachers was at the low level of the satisfaction, and their works were too much. 6) The urgent problems in the education of the special schools was shown with the next order in the significant level; to strengthen the synthetic administrative supports, to develop and to supply the learning materials, to develop the curriculum for the special classes, and so forth. 3. The existing state of the special classes 1) At present, the number of children receiving special education in special classes is 6,107 persons. 2) The major problems with which the existing special classes are confronted, such as correct identification, reducing the number of pupils per special classes, putting in good order of the basic facilities at the special class etc. should be solved. 3) It is an urgent problem that a long-term comprehensive plan for the establishment of special classes should be set up, because their continuity and connection with each other fields have not been considered on the establishment of them. 4. The teaching viewpoint of the teacher at the special classes 1) The special teachers' general point of view on the special classes was comparatively reached to the positive level. 2) There was generally such a tendency as they gave equal consideration to receiveing the academic achivement, to the life-centered education and to the occupational education. 3) The present special classes were shown not to have the cooperative relationship with the regular classes. Also, the level of the general teachers' attitude to the special classes and the degree of the understanding was about at the middle, but it was shown that the regular children regarded the special classes as strange. 4) The teachers' motive to take the special classes was shown comparatively to be more willing than to be reluctant. 5) It was shown that the evaluation and treatment for the special teachers was at the middle level of the satisfaction, and their works were too much. 6) The urgent problems in the education of the special classes was shown with the next order in the significant level; to strengthen the synthetic administrative supports, to develop and to supply the learning materials, and so forth. 5. The teaching viewpoint of the principals at the special classes. 1) The major problem with which the existing special classes are confronted, such as correct identification, reducing the number of pupils per special classes, putting in good order of the basic facilities at the special classroom and developing a lot of special education materials etc. should be solved without delay. 2) A great consideration should be given to select a dutiful special teacher with teaching method techniques. 3) The teaching practice for the special education should be planned to convert the school subject centered program to the life and vocational education program.

Generation Rescheduling Based on Energy Margin Sensitivity for Transient Stability Enhancement

Kyu-Ho Kim,Sang-Bong Rhee,Kab-Ju Hwang,Kyung-Bin Song,Kwang Y. Lee 대한전기학회 2016 Journal of Electrical Engineering & Technology Vol.11 No.1

This paper presents a generation rescheduling method for the enhancement of transient stability in power systems. The priority and the candidate generators for rescheduling are calculated by using the energy margin sensitivity. The generation rescheduling formulates the Lagrangian function with the fuel cost and emission such as NOx and SOx from power plants. The generation rescheduling searches for the solution that minimizes the Lagrangian function by using the Newton’s approach. While the Pareto optimum in the fuel cost and emission minimization has a drawback of finding a number of non-dominated solutions, the proposed approach can explore the non-inferior solutions of the multiobjective optimization problem more efficiently. The method proposed is applied to a 4-machine 6-bus system to demonstrate its effectiveness.
