We collected a total of 109 patients with intersex during the past 16 years (1966-1982). They were summerized as follows: Klinefelter's syndrome, the most common disease, was found in 76 cases, Turner's syndrome in 3 cases, true hermaphroditism in 5 cases, male pseudohermaphroditism in 5 cases, female pseudohermaphroditism in 13 cases and others in 7 cases in which 2 cases of XX male syndrome, 1 case of agonadism, 1 case of hernia uteri inguinale and 3 cases of unclassified intersex were included. 2 mosaic Klinefelter's syndrome showed 46/47 XX/XXY and 1 mosaic Turner's syndrome showed 45/46 XO/XX. The 5 patients with true hermaphroditism included 2 cases that had an ovary on one side and a testis on the other, 1 case, seperate ovary and testis on each side, 1 case, an ovary on one side and a seperate testis and ovary on the other and 1 case, an ovary on one side and an ovotestis on the other. Sex chromosome study on the true hermaphroditism revealed 46 XX in 2 patients and 46/46 XX/XY mosaicism in 3 patients. In male pseudohermaphroditism, all patients had a short and blind vagina. Of which, familial tendency was found in 1 case. Her sister had operation for sex reversal for female. In female psedohermaphroditism, all the patients were adrenogenital syndrome. Operations for clitoridectomy and vaginoplasty were performed on 10 patients. Hydrocortisone was given to 6 patients. Menstruation started to occur 6 months and 4 months after the medical therapy respectively in 2 cases.

The purpose of this study was to evaluate the kinematic characteristics of $5^{th}$ and $6^{th}$ hurdle clearances during the final of the 110-m hurdles at the IAAF World Championships, Daegu 2011. To this end, the hurdling motions of the top 4 ranked male hurdlers in the competition were analyzed. A total of 12 cameras were used to record their motions, with a sampling frequency of 120 Hz. The cameras were calibrated using $11{\times}2{\times}1\;m$ control objects that covered all of the lanes (1st~8th lanes). After analyzing all the data, we arrived at the following results. In the take-off phase, all athletes revealed similar take-off times (CT), and similar distances from the take-off to hurdleto (L1) and hurdle to landing (L2). In particular, Turner, ranked $3^{rd}$, had an inconsistent L2 and may need further training to correct it. In the flight phase, Richardson, ranked $1^{st}$, showed the longest flight distance, whereas Xiang, who was ranked $2^{nd}$, showed the highest CG height from the hurdle. For the step patterns, to increase the pitch frequency, Richardson and Xiang used shorter 3-step lengths than Turner and Oliver.

Noonan syndrome is characterized by a Turner-like phenotype and a normal karyotype associated with congenital abnormalities, such as short stature, variable mental retardation, hypertelorism, webbed neck, low posterior hair line, skeletal malformation and congenital cardiovascular defect. Two third of Noonan syndrome have cardiac anormalies, half with pulmonary stenosis. We have experienced two cases of pulmonary stenosis associated with other cardiac anomalies in Noonan syndrome. The first 31-year-old male patient had characteristic appearance of Noonan syndrome with severe infundibular pulmonic stenosis and patent foramen ovate. The second 28-year-old male patient had valvular and subvalvular Pulmonary stenosis with typical Noonan\`s face and stature. Pulmonary valvotomy and hypertrophied muscle bundles in the right ventricular cavity were resected in both cases. Patent foramen ovate was closed directly in the first case. Postoperative follow-up examinations revealed no symptoms and successful outcome.

The high rate of chromosomal abnormalities in patients with primary amenorrhea implies the need for routine screening for chromosomal abnormalities among such patients. This study was designed for the cytogenetic analysis of 236 patients with primary amenorrhea, which was referred to Yonsei University Medical Center, from January, 1, 1974 to December, 31, 1985. The results were as follows: 1. Of the 236 patients, 145 cases (61.4%) showed normal karyotype, and 91 cases (38.6%) showed chromosomal abnormalities. 2. Gonadal dysgenesis was found in 56 cases, consisting of 42 cases, Turner's syndrome, 12 cases, pure gonadal dysgenesis, and 2 cases mixed gonadal dysgenesis. a) Turner's syndrome was found in 42 cases, consisting of 18 cases of 45, X and 24 cases of mosaicism. b) Pure gonadal dysgenesis was found in 12 cases, consisting of 10 cases of 46, XX and 2 cases of 46, XY. c) Mixed gonadal dysgenesis was found in 2 cases, consisting of 1 case of 46, XY and 1 case of 45, X/46, XY. 3. Intersex was found in 80 cases, consisting of 35 cases of 46, XX, and 45 cases of 46, XY. 4. Congenital anomalies of reproductive system was found in 82 cases and all cases were normal karyotype.

The objective of this study was to investigate the useful components and potential antioxidant activities of 30 marine algae, collected from Jeju Island in Korea. The contents of bioacitve substance of extracts from marine algae, such total polyphenol and carbohydrate, were determined. The extract of Distromium decumbens had the highest amount of total polyphenol content (21.27%), and that of Gracilaria incurvata Okamura had the highest amount of total carbohydrate content (10.18%). The antioxidant activities of extracts obtained from algae were tested through the evaluation of DPPH radical and hydroxyl radical scavenging activity. The extracts of Distromium decumbens, Sargassum hemiphyllum (Turner) C.Agardh, Sargassum serratifolium (C. Agardh) C. Agardh and Acrosorium yendoi Yamada were found to have more than 80% DPPH radical scavenging activity and that of Dictyota okamurae (Dawson) $H{\ddot{o}}tning$, Schnetter, et Prud'homme van Reine, Myagropsis myagroides (Martens ex Turner) Fensholt, Sargassum serratifolium (C. Agardh) C. Agardh and Cladophora wrightiana Harvey showed more than 50% hydroxyl radical scavenging activity. These results suggest that algae collected from Jeju Island would be good raw materials for antioxidant.

This study attempted to discover the dimensions of Korean culture, with the presumption that the cross-cultural studies(Hofstede, 1980, 1997; Schwartz, 1992, 1994; Trompenaars and Hampden-Turner, 1997; House et al., 2004) have limitation to explain non-western culture including Korean culture. Even though there are some Korean cultural studies, they used heuristic approaches applying the authors' experiences and intuitions. This study applied the Cultural Consensus Theory to overcome the previous studies' shortcomings and to discover the dimensions that can be empirically proved by data. In specific this study conducted in-depth interview, used content analysis, did frequency analysis, and applied pilesort technique, multidimensional scaling and network analysis. As a result, this study obtained five categories: public self-consciousness, group-focused orientation, affective human relations, hierarchical culture, and result-orientation. It is expected that these dimensions can be used as important variables that may explain Korean social phenomena.

Purpose : We have performed this study to obtain reference data for the distribution of chromosomal aberrations in Korea. Methods : We analyzed 1,180 chromosomal study cases from Kwang ju Christian Hospital during the past 25 years. 756 cases suspected of characteristic chromosomal aberration syndromes and 424 cases with hermaphroditism, mild sexual abnormalities, multiple anomalies, or mental & growth retardation were included. Results : The male to female ratio of autosomal aberration syndromes was 1.2 : 1. 78.6% of autosomal aberrations were diagnosed under 1 year of age, whereas 89.8% of sex chromosomal aberrations were diagnosed over 12 years of age. Among 1,180 cases, 612 ones had chromosomal aberrations(51.9%) : 590 of 756 cases suspected of chromosomal aberration syndromes had aberrations( 78.0%), whereas 22 of 424 showing the above other features had aberrations(5.2%). Autosomal aberrations appeared in 514 cases(83.8%) and sex chromosomal aberrations appeared in 98 cases(16.2%). The most frequently observed abberation in autosomal aberrations was Down syndrome, followed by E, D, B, A and C group aberrations. The most common abberation in sex chromosomal aberrations was Turner syndrome, followed by Klinefelter syndrome and Fragile X syndrome. Conclusion : It is of vital importance that patients suspected of chromosomal aberrations undergo chromosomal analysis. Further advanced chromosomal staining and molecular genetic methods will raise the detection rate of chromosomal aberrations.

Purpose: We aimed to investigate the clinical characteristics and associated diseases in children with a horseshoe kidney and compared these data between children and adults. Method: We performed a retrospective analysis of the medical records and radiological findings of 43 patients diagnosed with a horseshoe kidney in the Busan Paik Hospital. The subjects were divided into the children's group (14 cases, age <18 years) and the adult group (29 cases, age ${\geq}18$ years). Results: The study group consisted of 17 males and 26 females with a median age of 34 years. In the children's group (14 cases), 5 subjects were male and 9 were female, with a mean age of $6.7{\pm}6.2$ years. Most of the subjects were asymptomatic and were incidentally diagnosed with horseshoe kidney during their evaluation for another disease. Among the associated diseases in the children's group, Turner syndrome was the most common (5 cases), whereas ureteropelvic junction (UPJ) stricture was observed in 2 cases (14.2%). None of the children exhibited abnormal renal function during the follow-up period. In the adult group (29 cases), 12 subjects were male and 17 were female, with a mean age of 48 years. Eighteen patients were incidentally diagnosed with horseshoe kidney during their evaluation for another disease, and 11 patients had hematuria or abdominal pain due to renal stones. Among the associated diseases in the adult group, Turner syndrome was the most common (5 cases), and UPJ stricture was observed in 5 cases; the other accompanying diseases included hydronephrosis and overactive bladder. Six patients exhibited decreased renal function (serum creatinine level >1.5) during the follow-up period. Conclusion: Horseshoe kidney is usually diagnosed incidentally in both children and adults. In the present study, we noted that Turner syndrome was the most common associated disease in children. In addition, most children were asymptomatic but had a high risk of urologic complications after the transition to adulthood. Therefore, children with horseshoe kidney require continuous follow-up.

Previous research on healthcare workers’ protection has concentrated on liquid barrier protection by providing impermeable personal articles such as latex gloves. This property is of high importance but since most blood-borne pathogen transmissions in the healthcare industry are caused by needle-stick injuries, protection from sharp invasive instruments should also be of high concern. And since latex and alike provide no protection against needle-stick injuries, new protective systems need to be developed and evaluated. This part of the study provides a review regarding the current practice of protection and the serious problems that arise from needle-flick injuries. Additionally, the development of new protective system is described. In part II of the study, evaluation of the new system will be provided.
