Purpose: This study was undertaken to identify the risk factors of genital infection by examining the genital hygiene practice followed by adult women of reproductive age. The results can be applied as basic data for health education and health management on female genital hygiene practices. Methods: Data ware collected by conducting an online survey, comprising 200 adult women of reproductive age. Genital infections according to genital hygiene practice were analyzed by simple logistic regression. Results: In this study, the Odds Ratio (OR) of genital infection occurrence of genital hygiene practices used were disposable briefs 4.11 (CI 1.79-9.39, p=0.020), feminine deodorant spray 3.13 (CI 1.37-7.15, p=0.007), deodorant, vaginal inserts (tabs/supp) 10.60 (CI 3.97-28.28, p<0.001), over the counter anti-itch products 3.73 (CI 1.67-8.34, p=0.001), blotting 11.47 (CI 4.62-28.48, p<0.001), natural sea sponge 4.98 (CI 2.04-12.15, p<0.001), reusable cotton pads 5.76 (CI 2.48-13.33, p<0.001), tampons 2.60 (CI 1.17-5.77, p=0.019), tampons/pads between periods 4.79 (CI 2.07-11.10, p<0.001) and tampons/pads combination 4.11 (CI 1.79-9.39, p=0.001) Conclusion: Our results indicated the necessity to refrain from unnecessary application of genital hygiene practices, which is highly related to genital infections identified in this study. There is a need to continue education for proper performance.

Purpose: The present study was designed to examine the impact of socioeconomic, health-related, and health behavioral factors on Korean people's intention to quit smoking. Methods: The subjects were 851 men and 145 women, aged 19 or more who had participated in the 2014 Korea National Health and Nutrition Examination Survey. The intention to quit smoking was categorized as "within 6 months," "after 6 months," or "no intention". The associations of the intention to quit smoking with sociodemographic, health related, and health behavioral factors were examined in a logistic regression. Results: In male smokers, the number of diseases, perceived somatotype, vigorous intensity leisure activity, aerobic physical activity, and smoking intensity had a significant influence on the intention to quit smoking. In female somkers, the economic status, number of diseases, walking activity, and moderate intensity leisure activity were significantly influential on the intention to quit smoking. Conclusion: To increase male smokers' intention to quit smoking, it should be emphasized that smoking is harmful to. Moreover, special attention should be paid to low-educated female smokers to increase their intention to quit smoking.

We conducted a study to 1) determine the indicators of gonadal maturity in male and female Korean walleye pollock Theragra chalcogramma for the purposes of artificial insemination; 2) establish the RNA/DNA ratio of mature eggs in this species; and 3) monitor the effect of refrigerated storage on egg viability and the motility of sperm collected from dead adult males. During the spawning season, the color of female gonads changed from orange to transparent, and that of male gonads changed from pale orange to milky white. The DNA content and RNA/DNA ratio of mature eggs were maintained without significant changes for approximately 6 h when eggs were preserved at $4^{\circ}C$. Sperm could be obtained from both milt and undiluted semen. Sperm obtained from milt ceased moving on the second day after isolation, while over 60% of sperm obtained from semen showed movement until the 13th day. Seven attempts were made to artificially inseminate mature eggs, of which two resulted in successful fertilization. The successful inseminations produced 94,000 and 5,000 fertilized eggs, respectively. This study shows that artificial insemination of walleye pollock is a viable strategy when natural propagation is not possible.

Purpose: Most research on risky drinking among adults in Korea has focused on problem drinking and high-risk drinking. This paper examines the nature of heavy episodic drinking_(HED) among adults and seeks to identify the risk factors for HED by analyzing differences by gender and age. Method: Participants were 3,886 adults aged 19-64 years from the database of the fifth Korean National Health and Nutritional Examination Survey (KNHANES-V, 2010). Data were analyzed by conducting the Rao_Scott chi-square test, an ANCOVA, and logistic analysis with SAS 9.2. Results: Individuals between 19 and 29 years of age had the highest HED among all age groups. Individuals between 40 and 49 (male adults) and those between 30 and 39 (female adults) showed HED associated with stress, suicidal ideation, smoking, and other health behavior-related variables. Risk factors that affected HED in male adults were age, educational status, and current smoking, while for female adults, the factors were age, educational status, employment, marital status, and current smoking. Conclusions: It is necessary to develop appropriate intervention programs that abate negative emotions and lessen the risk of HED in adults with consideration to gender and age differences.

A 33-year-old Korean woman, para 2, visited an obstetrics and gynecology clinic, Kumi-shi, Kyongsangbuk-do, due to postcoital spotting and flank pain. She had a tubal ligation 7 years before and demonstrated back pain during menstruation. She revealed a foul smelling discharge without complaint of itching. Enterobiw vermicularis eggs were demonstrated during microscopic examination of a smear taken from the posterior fornix of the vagina. On endoscopic examination of her vagina, a live worm was found in the posterior fornix. The worm was removed and identified as a female E. uemiculcris based on morphology. This is the first case report of vaginal enterobiasis in Korea.

The purpose of this study was to obtain the lingual morphology(angulation, inclination, horizontal and vertical contour) and lingual arch form of Korean adult with normal occlusion in order to provide the basic datas for lingual brackets and ideal lingual archwire. Dental models of thirty person with normal occlusion(Male : 16, Female :14) were selected for this study. Crown angulation, inclination. horizontal and vertical contour of lingual surfaces from Lt. 1st molar to Rt 1st molar of both upper and lower arch were measured. Lingual arcform was studied from copied papers of dental models attached Fujita lingual bracket. The results of this study were summarized as follows: 1. The average angulation and inclination of lingual surfaces of all tooth types for Korean adults with normal occlusion were obtained. 2. The average horizontal and vertical contour of lingual surfaces of all tooth types were obtained. 3. There were similar figures in horizontal and vertical contour of lingual surfaces between upper and lower molars, upper and lower premolars, upper and lower canines, upper central and lateral incisors and lower central and lateeral incisors respectively. It was possible that the use of those contour of bracket bases in common. 4. The average of lingual archform was provided, which was arch-shaped from canine to canine, linear along the premolars and molars with small offset bend between them, and where canines and premolars met, it was bent in a crank- shape. 3. There was no difference between lingual archform of male and that of female, although lingual archform of female was smaller than that of male in lower arch.

An endoparasitoid wasp, Cotesia plutellae, has been used for a biological control agent against the diamondback moth, Plutellae xylostella. It has a symbiotic polydnavirus in their reproductive tract, which is required for its successful parasitization. Here, we measured a specific replication time of the polydnavirus during female development of C. plutellae. We, also, analyzed the reproductive potentials of female C. plutellae under mating or different host conditions. At $25^{\circ}C$, pupal C. plutellae began to develop adult tissues such as compound eyes and wings since day 2. At day 5, all adult tissues including antennae were developed and were ready to emerge. With polyclonal antibody raised against C. plutellae polydnavirus, an immunobloting could confirm virus replication at day 4 during pupal stage. Virus particles could be visualized by transmission electron microscope in the oviduct lumen of day 5 pupae. After adult eclosion, venom gland and ovarian calyx increased in size, though ovarioles did not. Mated females layed large number of eggs (over $60\%$) at first 4 days during their mean longevity of ca. 8 days at $25^{\circ}C$. Unmated females showed less active ovipositional behavior, where all the eggs developed into males. C. Plutellae parasitized both P. xylostella and fall webworm, Hyphantria cunea. However, C. Plutellae developed faster and showed higher successful paarasitization in P. xylostella than in H. cunea.

The purpose of this research is to evaluate and compare the plaque removal ability of sonic brushing and manual brushing in order to present a method for continuous and effective oral hygiene control during orthodontic treatment. Nonextracted adolescent patients (male: 23 persons, female: 37 persons) and adult patients (male: 15 persons, female: 45 persons) outfitted with a fixed orthodontic appliance from their incisors to second molar, in both the maxilla and mandible, were divided into manual brushing and sonic brushing groups. A Philips oral healthcare HX-4401 sonic toothbrush was used, and the application of brushing for the two groups was standardized at two minutes. After brushing, the plaque score was measured with a modified Wilkin's PHP. The following results were achieved after comparing each group's plaque score. 1. In patients with a fixed orthodontic appliance when age was not accounted for, the application of sonic brushing exerted a beneficially decreased effect on the plaque score. (adolescents : p<0.01, adults: p<0.05) 2. When comparing the adolescent and adult groups in regard to plaque score, the adolescent group showed a more decreased effect. 3. When using the same toothbrush type, there was no difference between the adolescent and adult groups.

Using a sledge net, the benthic amphipods were taken over one cycle of the neap and spring tides in January 1993 at the sandy shore surf zone of Dolsando, southern Korea. From these samples, we investigated the diel and tidal effects on the intraspecific zonation of Pontogeneia rostrata. The density of p. rostrata was higher during neap tide than spring. Of three categories (adult males and females and juveniles), juveniles and males attained to its highest density during neap and spring tides, respectively. Length- frequency data show that the high mortality of juveniles seemed to occur in winter. In the surface at night, it is significant that juveniles were significantly more abundant during neap tide than spring, whereas both adult males and females were more abundant during spring tide than neap. This suggests that the vortical migration patterns of juveniles and adults vary with the type of tides. During flood of spring tide, more than $90\%$ of population collected at the area above the mean sea level (MSL) were adults. With a decrease of female/male ratio, size of males increased there but that of female did not change, indicating an active migration of large males. This behavior can provide an extension of distribution area far large males, and also give a competitive advantage to large male against small one for mate and feeding. Although adult p. rostrata was collected at 100 cm above MSL at night during spring tide, a major portion of population as usually present on the shore below MSL. The center of zonation was restricted from 50 cm to 250 cm below MSL.

Adult-onset Alexander Disease (AOAD) is a rare genetically determined leukoencephalopathy that presents with ataxia, spastic paraparesis, or brain stem signs including speech abnormalities, swallowing difficulties, and frequent vomiting. The diagnosis of AOAD is frequently proposed based on the findings on MRI. We demonstrate two cases (37-year-old female and 61-year-old female) with characteristic imaging findings and changes in follow-up MRI in patients with AOAD, which were confirmed via glial fibrillary acidic protein (GFAP) mutation analysis. On MRI, the typical tadpole-like brainstem atrophy and periventricular white matter abnormalities were noted. The presumptive diagnoses were made based on the typical MRI appearances and, subsequently, confirmed via GFAP mutation analysis. Follow-up MRI demonstrated the progression of atrophy in the medulla and upper cervical spinal cord. Our report could help raise awareness of characteristic MRI findings of AOAD, thus helping clinicians use GFAP analysis for AOAD diagnosis confirmation.
