PURPOSE: The purpose of this study was to develop a sexuality education course of study for students in the lower grades of elementary school. METHOD: On the basis of the sexuality education guidebook for elementary school students published by Korea Ministry of Education & Human Resources Development, the state-designated textbooks for first to third grade were analyzed. RESULTS: 1) In the category of physical and psychological development, physical development and psychosexual development content were covered, but not sexual health content. 2) In the category of understanding of human relationship, marriage and family, and the opposite sex and love were presented but self-determination and selection were only partially presented. 3) In the category of sexual culture and sexual ethics, sexual role in society was covered, but not social environment or equality of the sexes. CONCLUSION: These results suggest that content on sexuality which is not covered in textbooks for students in lower grades should be included in other school courses or activities in class.

OBJECTIVETo investigate the actual condition of the sexual physiological and psychological development of the high school students in Yibin in order to get a reliable basis for sexual education of the teenagers.

METHODSWith a proportion of 1% to the whole, 2,770 students were randomly selected from eight high schools in the urban and rural areas of the city. We devised a questionnaire and asked each student to fill in his or her answers presently.

RESULTSSo far as sexual physiological and psychological development was concerned, the high school students of Yibin were found rather precocious, with very little sexual knowledge and psychological endurance in sexual affairs and a relative lack of sexual education.

CONCLUSIONIt is imperative to extend the scope of puberty sexual education in high schools. Teenagers must be taught different kinds of sexual knowledge at different periods of growth as well as how to avoid sexually transmitted diseases and gestation. The sexual knowledge level of the teachers must also be raised. It is a must to establish service or specialist consultation hot lines about sexual knowledge for teenagers. Parents are expected to change their traditional views and assume an active role in the joint efforts of sexual education for their children.

OBJECTIVES: To evaluate the effect of parity & delivery method on female fecal incontinence. METHOD: Based on 213 cases of 4 different delivery method and 40 cases of one non-delivery group, a retrospective analysis of the prevalence of female fecal incontinence, between January 1996 and December 1998, was done. With delivery mode, 4 different groups were: first vaginal delivery group , two or more vaginal deliveries group, first cesarean section group, and first vaginal delivery followed by cesarean section group. All subjects were examined by questionaire or phone about the experience of fecal incontinence after delivery. In cases of fecal incontinence , we reviewed the obstetric complications with medical records. RESULT: There was no fecal incontinence in the non-delivery group. The incidence of fecal incontinence in the two or more vaginal delivery group(11.7%, 9/77) and the first vaginal delivery followed by cesarean section group(18.1%, 8/44) was higher than the first vaginal delivery group(6.8%, 3/44), and the first cesarean section group(2.1%, 1/48)(P<0.05). The obstetric complications in fecal incontinence cases were: a prolonged second stage, anal sphincter laceration, vacuum extraction, a large baby etc. CONCLUSION: Fecal incontinence was significantly correlated with the number of vaginal deliveries and obstetric complications during delivery. Fecal incontinence after the first vaginal delivery or vaginal delivery followed by cesarean section are very important factors in choosing the next delivery method.

Hermann Hesse's personal life (1877–1962) is characterized by traumatization caused by suppressive pietistic discipline of his parents during his youth, and depression in his middle age accompanied by psychoanalysis treatment. At the age of 15, he was admitted to mental institutions due to defiant behavior. With this traumatic experience, his psychosexual development seemed inhibited during his adolescence. At age 39, depression developed precipitated by the death of his father. Hesse had received Jungian psychoanalysis from Dr. Lang and Dr. Jung over a 10-year period. However, psychoanalysis could not prevent the recurrence of depression. His appreciation of psychoanalysis became critical. Meanwhile, Hesse announced that he had been a Protestant Christian. In his 50s, he began to create new novels which, beyond polarity based on Jungian psychoanalysis, described the journey toward a greater harmonious and spiritual oneness. Pietism was at one time the reason of his pain, but became life-long support for Hesse's spiritual maturity. He was diagnosed with type II bipolar disorder. The main dynamic factors are thought to be ambivalence, feelings of guilt regarding his aggression toward his parents, and sexual conflict. His coping mechanisms seemed to include pietistic self-control, avoidance, scholarship and creation of literature. By writing the autobiographical Bildungsromans, Hesse tried not only to master his own personal problems but to enlighten readers. However, it seemed that he could not overcome the feelings of guilt associated with leaving his father.

OBJECTIVE: In patients with hemorrhagic cavernous malformation(CMs) located in critical brain region that were thought to pose an excessive risk for microsurgical resection, Gamma Knife radiosurgery(GKRS) has been used as an alternative management option for these lesions. The purpose of this study is to evaluate the efficacy of GKRS for hemorrhagic CMs. METHODS: Among the patients of hemorrhagic CMs who had been treated by using Leksell Gamma Knife, 20 patients who had been followed up more than 2 years were analysed for their postradiosurgical results. RESULTS: Mean target volume was 3199mm3(224-9300mm3). Mean maximal dose was 28.9Gy(15-50Gy) and mean marginal dose was 16.5Gy(9-25Gy). 50% isodose or greater was used for the margins of the lesions. Mean follow-up period after GKRS was 51 months(24-112months). During the follow-up period, 3 patients suffered from rebleeding at 5, 6, and 28 months after radiosurgery, respectively. Two cases had a rebleeding in latency period(time interval from GKRS to its maximal effect on vascular obliteration, usually 2-4 years in case of CMs) and another one case after latency period. The annual rebleeding rate was 3.1%(first 2 years after radiosurgery 5%, thereafter 1.7%). Delayed radiation-induced complications occurred in 4 cases at 4, 7, 15 and 18 months after radiosurgery. CONCLUSION: The use of GKRS as an alternative management strategy to the hemorrhagic CMs which located in critical brain region and so had potential risk for microsurgical resection is thought to be available. And the GKRS would reduce the rate of rebleeding of CMs, especially after 2-3 years of latency periods.

STATEMENT OF PROBLEM: Implant-type distractor uses a removable distraction device that has an appearance similar to that of a dental implant and utilizes many of the same techniques for placement as are used for dental implants. MATERIAL AND METHOD: In this study, 48 implant type titanium distractors were inserted into the osteotomized alveolar bone of 12 beagle dogs. After a 7-day latency period, the alveolar bone was augmented by 5mm vertically at a rate of 1.0 mm/day. The dogs were sacrificed after 4weeks, 8weeks and 12 weeks for radiographic, histologic, and histomorphometric analysis. RESULTS: Copper equivalent value showed significant difference between 4 weeks and the other weeks(8, 12 weeks)(p<0.05). But there was no significant difference between maxillary and mandibular groups. In the bone to metal contact analysis, there was a significant difference between 4 weeks and 12 weeks(p<0.05). On the contrary, there was no significant difference between maxilla and mandible. The bone area showed significantly higher values in 12 weeks compared to 4 weeks(p<0.05). Histologically mineralization began at the host bone margins. At 12 weeks, increasing accumulation of Ca++ element was confirmed. CONCLUSION: From the results above, the new bone formation was increased according to consolidation period. Especially there was significant difference between 4 weeks and 12 weeks(p<0.05). Implant type distractors used in this study to augment vertical ridge defect may prove to be a clinically useful treatment option in selected cases.

Dermatofibrosarcoma protuberans(DFSP) is an unusual, locally aggressive, cutaneous neoplasm of low grade malignancy. Several histologic variants have been described. Among them, fibrosarcomatous dermatofibrosarcoma protuberans is associated with a higher rate of local recurrence and distal metastases as well as a shorter latency period of time until recurrence than does ordinary DFSP. As a result, it needs more intense treatments and more vigorous follow up. A 37-year-old man presented with an asymptomatic erythematous hard nodule and several reddish papules on the chest for 2 years. Histopathologic examination revealed fibrosarcomatous dermatofibrosarcoma protuberans. We, herein, report an unusual case of fibrosarcomatous dermatofibrosarcoma protuberans.

Distraction osteogenesis(DO) is defined as a gradual mechanical process of mechanical stretching two vascularized bone surface apart with a critical rate and rhythm such that new bone forms within the expanding gap, reliably bridges the gap, and ultimately remodels to normal structure. DO has become a mainstay in bone tissue engineering and has significantly improved our armamentarium for reconstructive craniomaxillofacial procedures. But the molecular and biological mechanisms that regulate the formation of new bone during distraction osteogenesis are not completely understood. BMPs are potent osteoinductive agents. Our hypothesis was that BMPs, especially BMP-2 and BMP-4, might play an importent role in the signaling pathways that link the mechanical forces created by distraction to biological responses and in promting new bone formation. Using a rabbit's mandible, we investigated the expression of BMP-2, -4 at different time points during distraction osteogenesis. The purpose of this study is to research the pattern of expression of BMP-2, -4 in new bone formation during distraction osteogenesis of the rabbit mandible. The experimental group was applied gradual distraction (0.7mm a day by twice a day, 4.9mm in total, for 7 days) and the control group was carried out osteotomy alone. They were examined clinically, histologically, and by RT-PCR analysis. On 3 days after osteotomy, the high level of expression of BMP-2, -4 was detected. But, the expression of BMP-4 was decreased during latency period. As distraction was started, its expression was increased and maintained till postoperative 28days. In control group, the expression of BMP-4was remarkably decreased till postoperative 14 days. On the other hand, the expression of BMP-2 was no difference between experimental group and control group. The expression of BMP-4 was maintanined at high level during the entire experimental period in both group. These findings suggested that excellent bone formation during distraction osteogenesis is associated with enhanced expression of BMP-4 genes by mechanical tension stress.
