Purpose: The purpose of this study was to examine how effective the existing sex education programs and letter to parents from school were for their know ledge and attitudes towards sex of the middle school students. Methods: Subjects were selected from first grade students in a middle school from May 30 through July 19, 2005. The subjects were divided into three groups of 70 students each, two experiment groups and one control group. The study was conducted by nonequivalent control group non-synchronized design. The information letter from school to parents was made into four editions on double-sided A4 size paper and was handed out to students during weekly meeting. Both the students and their parents were required to read it and the parents were told to sign the papers. The sex education program applied in this study was recomposed based on the programs which were previously made by Sun Hee Park(2004) and Eun Ja Jung(2000). Content provided in the sex education program is identical to the one's in the information letter to parents. Experimental group 1 was required to read the four information letters to parents for two weeks, together with their parents. Group 2 experienced the sex education program four times in two weeks of time. The above two experimental groups and the control group were assessed on their knowledge and attitude towards sex twice, before and after the experiment. Results: There were significant differences in sexual knowledge about sex between the three subject groups and such data supports the first hypothesis. There was significant difference in attitude towards sex between the three subject groups and such data support the second hypothesis. Conclusion: According to the experiment results, both the information letter to parents and programs about sex education were effective for the middle school students. Yet, teaching students with the program format was more successful than handout formats. However, using information letters to parents to educate students does not waste any school hours, so if school nurses can provide the students more papers, the educational effect will be greater.

As sports infiltrates each field of modern society and becomes familiar, sports wear was changed functionally and was introduced and enveloped into everyday dress. Modern sports wear has been the settled in everyday life deeply and become the clothes of life which are worn regardless of place, time and age. The aim of this paper was to clarify what kind of fashion of sports style would be given to the modern people. In this study, sports wear which has become everyday dress classified from a gender point of view. It was divided into masculine image, feminine image, and neutral image. Sports wear of masculine image generated a silhouette which emphasized the shoulder with the aspiration for youth and health. Wide shoulder was considered as the symbol of masculine beauty and the expression of healthy beauty. It was reflected well in body conscious look. And owing to the development of up-to-data materials, innovation of design, and the study of human body technology, the functional character was settled in the sports wear which showed masculine image. Sports wear of feminine image was represented fashion of body exposure, body feet with body conscious look, and romantic mode. This image was expressed fashion as comforts, pleasant, active design, materials, color, and romantic feminine beauty. Sports wear of neutral image was expressed into unisex clothes. This cloths have no difference in gender, age, and class. It was used as casual sports wear. In the 1960s, young generation participated in such street sports as street basketball and skate. They usually sore the sports wears of neutral image such as cycling, skating, and ski. In the materials of sports, the development of up-to-data material like lycra made the sayings lifelike, “up-to-data material is the second skin” It show that glamorous feminine image and strong masculine image coexisted. The contemporary concept of sportswear is no longer limited to those clothes for sports found in such places like tennis court or swimming pool. Now, the sports wear become more like casual activity wear all classes of people can enjoy in their life regardless of where they are, when they wear, and even how old they are.

This study is to examine personal color - preferred color, well-matched color and the relations between preferred color and the well-matched color. Focus is also placed on how sexual difference influences color temperature preference. For data collection, a questionnaire including color stimulus was employed. The subjects of this study were the male and female college students who lived in Pusan. The results of the research are summarized as the following : In view of preferred color, male subjects preferred KEY2 color(warm) in red, pink, and yellow, and preferred KEY1(cool) in green and blue. While most subjects showed the same signal, in green, male preferred KEY1 color and female preferred KEY2 color. Concerning preferred personal color type, KEY1 type person liked KEY1 color except red, and KEY2 type person liked KEY2 color except blue. This shows that people prefer the focused color presenting its own traits. In view of well-matched color, most subjects liked KEY2 color in red, yellow, pink, and they selected KEY1 color in blue as the well-matched color. However, in green, each sex showed different preferences; while male subjects selected KEY1 color as the well-matched color, female ones selected KEY2 color. In each personal color type, KEY1 type male evaluated KEY1 color as the well-matched color, KEY2 type male evaluated KEY2 color except blue. KEY1 type female chose all the KEY1 color as well-matched colors, and KEY2 type female chose KEY2 color. The well-matched colors are similar between male and female subjects. In over 80 percentage of the answers, the preferred colors coincided with well-matched colors. KEY1 type persons chose KEY1 color, and KEY2 type person chose KEY2 color as the well-matched color. These results show that there is a meaningful relationship between the preferred color and well-matched color.

This study examined the properties of photons and the dose distribution in a human body via a simulation where the total body irradiation(TBI) is performed on a pediatric anthropomorphic phantom and a child size water phantom. Based on this, we tried to find the optimal photon beam energy and material for beam spoiler. In this study, MCNPX (Ver. 2.5.0), a simulation program based on the Monte Carlo method, was used for the photon beam analysis and TBI simulation. Several different beam spoiler materials (plexiglass, copper, lead, aluminium) were used, and three different electron beam energies were used in the simulated accelerator to produce photon beams (6, 10, and 15 MeV). Moreover, both a water phantom for calculating the depth-dependent dosage and a pediatric anthropomorphic phantom for calculating the organ dosage were used. The homogeneity of photon beam was examined in different depths for the water phantom, which shows the 20%-40% difference for each material. Next, the org an doses on pediatric anthropomorphic phantom were examined, and the results showed that the average dose for each part of the body was skin 17.7 Gy, sexual gland 15.2 Gy, digestion 13.8 Gy, liver 11.8 Gy, kidney 9.2 Gy, lungs 6.2 Gy, and brain 4.6 Gy. Moreover, as for the organ doses according to materials, the highest dose was observed in lead while the lowest was observed in plexiglass. Plexiglass in current use is considered the most suitable material, and a 6 or 10 MV photon energy plan tailored to the patient condition is considered more suitable than a higher energy plan.

After application of silver nitrate on every newborn, the incidence of gonococcal conjunctivitis was markedly decreased. But recently neonatal conjunctivitis due to chlamydia infection is increasing, so clinical observation was made on 26 newborn infants who showed eye discharge from June 1st to August 31st 1989. The results were as follows. 1. The incidence of chlamydia infection among neonatal Conjunctivitis was 34.6%. 2. The most common age at diagnosis was 6-15days of life and there was no sexual prepondrance. 3. There was no significant difference on clinical symptoms between chlamydia conjunctivitis and other Conjunctivitis. 4. Of 26 infants examined. 16 cases revealed no growth on routine bacterial culture. Of the organism cultured, P. aeruginosa was the most common agent(19.2%) and followed by S. aureus(11.5%) and S. epidermidis(7.6%). In one case of chlamydia I conjunctivitis, there was concurrent S. aureus infections. 5. On this study, Giemsa stain did not give significant diagnostic aid of chlamydia conjunctivitis.

It has been known that "Gobongeonyangdan" has a certain effects on male sterility in the field of oriental medicine. This thesis purposes to prove such effects of the medicine especially concerning sex hormones and hematogenesis. In the study were used three groups of rats: two of those were treated with Gobongeonyangdan with a variety of quantity and the other untreated. The experiment spans for 35 days: tests upon those subjects were done three times on the 7th, 21st, and 35th day checking the change of testosterone, estradiol, LH, FSH and iron in the serums, and RBC, hematocrit and hemoglobin levels. The results obtained from the study are as follows: 1. The content of testosterone in the serums marked a significant increase in both treated groups in comparison to the untreated group. 2. The content of estradiol in the serums showed a significant increase in the treated groups as to the untreated. 3. The content of LH in the serums increased significantly in the treated groups as to the untreated. 4. The content of FSH in the serums also increased remarkably in the two treated groups as to the untreated. 5. The content of iron in the serum was seen to be increased in the treated groups rather than the untreated group. 6. The RBC was observed to show a tendency toward a significant increase in both the treated groups in comparison with the untreated group. 7. The hemoglobin levels were also increased significantly in the treated groups as to the untreated. 8. The hematocrit levels were decreased significantly in one of the two treated group(sample A group) and there was no difference in the other group(sample B group) in comparison with the untreated group. Consequently, "Gobongeonyangdan" may well be a favorable medicine for patients two have sexual functional disorder and it is also effective on hematogenesis.

Objective: These studies were undertaken to evaluate the effects of the different administration duration of Morindae Radix extract solution on spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testes and the activities of sperm hyaluronidase. Materials and Method: We used 8-week-old ICR mice and administered 0.3mg/g extract solution of Morindae Radix once a day for 30, 60, 90 and 120 days. The control group was administered normal saline in the same way and duration. We examined the number of total, motile and normal sperm from the cauda epididymis. We also compared the testicular tissue, especially seminiferous tubules, between the control and treated groups by histochemical methods. Finally, we observed the difference of sperm hyaluronidase activities between the control and treated groups. Results: Significant administration duration-dependent differences were observed in the concentration of total sperm, motility and normality of spermatozoa of the Morindae Radix extract solution administered groups compared to the control group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Morindae Radix extract solution administered groups compared to the control group. Also, the activity of hyaluronidase was significantly increased in the Morindae Radix extract solution administered groups compared to the control group. Conclusions: This study shows that the beneficial effect of Morindae Radix extract solution on the concentration, motility and morphology of sperm, the testicular tissues and the activities of sperm hyaluronidase increased the greater the duration the mice were administered it. We suggest that Morindae Radix may be useful for the treatment of male sexual dysfunction and infertility.

Fusarium asiaticum of the F. graminearum species complex causes head blight in small-grain cereals. The nivalenol (NIV) chemotypes of F. asiaticum is more common than the deoxynivalenol (DON) chemotypes of F. asiaticum or F. graminearum in Korea. To understand the prevalence of F. asiaticum-NIV in Korean cereals, we characterized the biological traits of 80 cereal isolates of F. asiaticum producing NIV or 3-acetyl-deoxynivalenol (3-ADON), and 54 F. graminearum with 3-ADON or 15-acetyl-deoxynivalenol (15-ADON). There was no significant difference in mycelial growth between the chemotypes, but F. asiaticum isolates grew approximately 30% faster than F. graminearum isolates on potato dextrose agar. Sexual and asexual reproduction capacities differed markedly between the two species. Both chemotypes of F. graminearum (3-ADON and 15-ADON) produced significantly higher numbers of perithecia and conidia than F. asiaticum-NIV. The highest level of mycotoxins (sum of trichothecenes and zearalenone) was produced by F. graminearum-3-ADON on rice medium, followed by F. graminearum-15-ADON, F. asiaticum-3-ADON, and F. asiaticum-NIV. Zearalenone levels were correlated with DON levels in some chemotypes, but not with NIV levels. Disease assessment on barley, maize, rice, and wheat revealed that both F. asiaticum and F. graminearum isolates were virulent toward all crops tested. However, there is a tendency that virulence levels of F. asiaticum-NIV isolates on rice were higher than those of F. graminearum isolates. Taken together, the phenotypic traits found among the Korean F. asiaticum-NIV isolates suggest an association with their host adaptation to certain environments in Korea.
