Aiming to appraise student's health status and recommend improvement and strengthening of the school health services, statistical analysis of the results of health examination were done with summarized data which were collected nation-wide through the Ministry of Education. After analysis of data obtained, the results of the study summarized as follows; 1) Requested Adequate care Requested Adequate care showed from 5 % to 3% in 1962 and 1984 respectively. In sexes, Requested Adequate in girls (2.8%) more apparent than in boys (2.5%) 2) Eyes i) Weak vision, abnormal refraction of eyes (myopia, hypermetropia and astigmatism), eye diseases (trachoma, others) were found as shown in the Table 2, Figure 3. Weak vision and abnormal refraction of eyes showed from 2 % (Elementary), 5 % ( Secondary) to 4 % (Elementary), 14 % (Secondary) in 1962 and 1984 respectively. In both sexes, the older the age of students the more weak vision and abnormal refraction of eyes had rapidly increased especially in over 15-year old. ii) Eye diseases (trachoma, others) showed from 2% to age of students the more diseases had students. 3) Ear, nose and pharynx Hearing disturbance, ear diseases (otitis mediae, others), nose (empyema, hypertrophy) and pharynx diseases were found as following 1) Hearing disturbance was found from 0.3%(Elementary), 1 %(Secondary) to 0.05 % (Elementary), 0.4 % (Secondary) in 1962 and 1984 respectively, however, recently the older the age of students the more had students. ii) Ear diseases showed from 1.7 % (Elementary) 1.0 % (Secondary) to 0.3 %(Elementary), 0.5%(Secondary) in 1962 and 1984 respectively. iii) In diseases of the nose and pharynx, tonsilitis showed from 2.5% (Elementary), 3.5 % (Secondary) to 1.8 % ( Elementary). 2.5% (Secondary) in 1962 and 1984 respectively. 4) Skin Infectious skin diseases and other skin diseases were found from 1.5% to 0.6% in 1962 am 1984 respectively. 5) Teeth Dental caries (in milk and permanent teeth) and otner oral diseases are shown from 12 % (Elementary), 8%(Secondary) to 75%( Elementary), 25% (Secondary) in 1962 and 1984 respectively. 6) Other defects and diseases A relatively higher morbidity was shown in the tubercular diseases, in anemia, and in heart diseases among the tuberculous diseases, nodular diseases, Pleurisy, heart diseases, anemia, beriberi, hernia, neurasthenia, speech difficulty, mental disorders, bone dysformity, motion difficulty of extremities. In both sexes, tuberculous diseases were found almost equally in both sexes and anemia in girls was more apparent than in boys. Trying to provide more effective health services in schools : i) A better and more effective physical examination should be carried out in each school and prior to the physical examination, the qualified daily observation of children by teacher should be keenly practiced. ii) According to the results of the required annual physical examination the leading cause of morbidity were dental caries, myopia, angina and otitis mediae and fore these diseases follow up should be carried out. iii) For prevention and treatment of diseases and defects health education for students in the classroom as well as to parents is urgently requested.

This study aims to evaluate psychometric properties of the korean version of the secondary traumatic stress scale. A total of 238 practitioners in child protection agencies are recruited using complete enumeration method. The psychometric properties of the instrument are tested by item-analysis, exploratory factor analysis,(EFA) and convergent and construct validity. The results show that the internal consistency values for the two dimensions of the K-STSS are good. While the convergent and discriminant validity is empirically confirmed, the construct validity is not supported. The EFA with the common factor analysis method reveals the factor structure in the observed variables. The findings of the study confirmed that although it was reliable and discriminant, the K-STSS needed to be explored more in a way to support construct validity.

Myxobacteria produce diverse secondary metabolites for predation, self-defense, intercellular signaling, and other unknown functions. Many secondary metabolites isolated from myxobacteria show pharmaceutically useful bioactivity such as anticancer, antibacterial, and antifungal activities with a unique mechanism of action. Therefore, a large number of myxobacterial strains have been isolated globally and many bioactive compounds have been purified from them. However, 16S rRNA database analysis indicates that there are far more types of myxobacterial species in the wild than have ever been isolated, and genome sequence analysis suggests that each myxobacterium is capable of producing much more metabolites than already known. In this article, the current status of studies on the secondary metabolites from myxobacteria, their biosynthetic genes, biological functions, and transcriptional regulatory factors governing gene expression were reviewed.

Purpose: Secondary breast reconstruction is defined as a whole reconstructive procedure to correct complications and to improve the aesthetics when a patient is dissatisfied with her initial reconstruction. We would like to present these particular procedures on previously failed breast reconstruction with analysis of unsatisfactory results. Methods: From June 2002 to August 2008, we performed secondary breast reconstructions for 10 patients with failed breasts. Six patients with implant failure underwent secondary breast reconstructions using free TRAM flaps after the removal of implants. Two patients with partial loss of pedicled TRAM flaps underwent secondary breast reconstruction using Latissimus Dorsi flaps. Two patients with 1 total loss of free TRAM flap and 1 extensive fat necrosis underwent secondary breast reconstruction using implants. Results: The average age of the patients were 36.4 years (26 ~ 47 years). All flaps survived completely and had relatively good aesthetic results in free TRAM cases. There was breast asymmetry in one patient using cohesive gell implants in total loss of previously free TRAM patient, which was corrected by exchanging the implants and placing dermofat grafts. Conclusion: Secondary breast reconstruction differs from primary procedures in several aspects; there are changes in the anatomy and tissue environment of the breasts, and various limitations in choosing reconstruction methods. In addition, the patients may be uncomfortable with previous complication. It is important to consider various factors before deciding to undergo a secondary breast reconstruction carefully with informed consent.

Near-wake flow field downstream of a circular cylinder in the wake-transition regime where fine-scale secondary vortices have a spanwise wavelength of around one diameter has been studied by means of phase-averaging from cinematic PIV data. A cross-correlation algorithm in conjunction with the FFT(Fast Fourier Transform)analysis and an offset correlation technique is used for obtaining the velocity vectors. Which the help of very high sampling rate compared to the shedding frequency, it is possible to obtain phase-averaged flow fields although the shedding is not forced but natural. Phase -locked three-dimensional vortical structures are reconstructed form the phase-averaged data in one x-y(cross-sectional) and several z-x(spanwise-streamwise)planes. In this process of phase-averaging in a z-x plane, a technique to freeze the secondary vortices relative to the centerline is applied. The formation process of the secondary vortices is shown by considering spatial relations between the primary Karman and the secondary vortices and their temporal evolutions.

Secondary schools in Korea have been faced with several critical problems in their science education. Among them the most fundamental are the problems which involve the development and operation of science curricula. This study had, therefore, its objective to develop the suggestions for sabstantial science curricula of secondary schools. Actually the objectives are trifold as following specific description. ${\circ}$Analysis of the rationale and theory of science curricula. ${\circ}$Status survey of secondary science curricula and identification of the problems in development and operation of the curriculum in foreign and Korean secondary schools. ${\circ}$Development of suggestions for substantial science curriculam of secondary school. In order to attain these objectives the methods of literauare survey. questionaire and interview were used. Through these methods several problems are found and identified. The major findings and problems identified in this study are: ${\circ}$aims, goals, and objectives of science education are not dfferentiated. ${\circ}$the curricula show discipline-centered seleetion and organization of the content:neglect the relationship of science-technology-society and life-world context. ${\circ}$shortage of weekly instructional hours for science subjects. Other findings and problems are described and the descriptions of the suggestions for substantial curricula are followed at the end of this paper.
