Thirty two rice cultivars which have been cultivated or used as breeding materials in Korea were tested for screening rice cultivars resistant to leaf blast at adult-plant stages in the blast nursery hill plots. When compared on the basis of disease severities in individual leaves at different growth stages of rice plants under natural field infection, the 16 indica-japonica hybrids tested were highly resistant but the 16 japonica cultivars tested showed various degrees of resistance to leaf blast. With aging of rice plants, the quantitative levels of resistance to leaf blast increased in all the cultivars, although the levels of resistance to leaf blast varied according to rice genotypes. The leaf position of rice plants in which changed from susceptible to resistant reactions varied also with rice genotypes. The susceptible reactions of the rice cultivars to Pyricularia oryzae were distinctly changed to a resistant reaction on upper leaves of rice plants. The rice cultivars, in which the quantitative level of resistance to leaf blast was higher, were resistant on the lower leaves of rice plants. The cultivars Akibare, Palkeum, Jinheung, Olchal, Dobong and Ginga which drastically decreased blast infection at late growth stage were evaluated as adult-plant-resistant to leaf blast in the field. The adult-plant-resistant cultivars became resistant to leaf blast, both qualitatively and quantitatively, as rice plants matured.

Transglutaminase (TGase), which forms linkages among proteins, has been used to improve food quality. In the current study, quality characteristics such as color values, texture profile parameters, and sensory profiles of the frozen surichwi (Synurus deltoids) rice cake made using transglutaminase (TGase) treated-rice flour were investigated, with a view to producing high-value rice products. The results indicate that Hunter color values (L and b) and TPA parameter values (hardness, gumminess and chewiness) of frozen surichwi rice cake made with TGase-treated rice flour were significantly changed, and that these properties may be applied to improve the sensory qualities of final products. Also, the sensory acceptability scores related to color, appearance, taste and texture, as well as overall acceptability of the TGase-treated frozen surichwi rice cake, were found to be significantly higher compared to controls. In conclusion, the results clearly indicate that TGase-treated rice flour carries the potential to improve the overall quality of frozen rice cake, and that surichwi is an effective ingredient for sensory profiles.

117 undergraduate ophthalmic optics students volunteered to participate in this study. They ranged in age from 19 to 26 years. Subject, had best corrected visual acuity of at least 1.0 in both eyes, no strabismus, no amblyopia, and no history of ocular surgery. 37 subjects are esphoria and 25 subjects are $3{\Delta}$ and less, and the rest of 12 subjects show more $4{\Delta}$. Average phoria amount is $2.96{\Delta}$ at far distance and $1.08{\Delta}$ at near distance, respectively. The variation of phoria amount in far and near distance, unchanging subjects are 3, 8 subjects are increase esophoria amount, and 26 subjects are phoria amount decreasing or appear exophoria. The reason of esophoria amount is decreasing in near distance, and the results are convergence burden decreases. At positive relative convergence, the expected value in far distance, blurred point is 7, break point is 16, and recovery point is 12. And negative relative convergence, break point is 7 and recovery point is 13, respectively. Moreover, at positive relative convergence, the expected value in near distance is blurred point is 8, break point is 7 and recovery point is 22. And negative relative convergence, blurred point is 2, break point is 8 and recovery point is 12, respectively.

This paper is the first geomorphological research on TAENGNIGI which is famous for old geography book in Korea. The purpose of this paper is to explain TAENGNIGI in modem geomorphological viewpoint and then, lay the foundation for establising Korean style geomorphological terms. It also analyzes TAENGNIGI from Lee, Jung-Hwan(the authority of TAENGNIGI's geomorphological viewpoint. The main results are summarized as follows. Firstly, It is estimated that TAENGNIGI is a geography book including human and physical geography. Secondly, in spite of Lee, Jung-Hwan's some metaphysical explanation of feng-shui in TAENGNIGI. his geomorphological appreciative eye is excellent. Thirdly, it is possible that a Korean style geomorphological term will be established based upon the result of this paper on TAENGNIGI. Fourthly, Lee, Jung-Hwan indicted geography(地理), profit(生利), human nature(人心), landscape(山水) as factors in selecting of people's dwelling place(可居地) and he described that geography(mainly physical geography) was mostly important among the four factors mentioned in selecting of people's dwelling place. Especially he also mentioned that good landscapes have a favorable influence upon the forming of people's character.

Objective: To compare the clinical outcomes between oral micronized progesterone and dydrogesterone as a luteal phase support in stimulated intrauterine insemination (IUI) cycles. Methods: A retrospective analysis was performed in 183 IUI cycles during January 2007 to August 2009. Superovulation was achieved by using gonadotropins combined with or without clomiphene citrate. The luteal phase was supported by oral micronized progesterone 300 mg/day (n=136 cycles) or dydrogesterone 20 mg/day (n=47 cycles) from day of insemination. Results: There were no significant differences in clinical characteristics such as age of female, infertility factors, number of mature follicles ($\geq$16 mm), total motile sperm counts, and endometrial thickness on triggering day between the two groups. The clinical pregnancy rates per cycle were similar between the two groups (21.3% in the micronized progesterone group vs. 19.1% in the dydrogesterone group, p=0.92). The clinical miscarriage rate tended to be 3-fold higher in the micronized progesterone group (34.5% vs. 11.1%, p=0.36). Conclusion: Supplementation of oral dydrogesterone as a luteal support has similar clinical outcomes compared with oral micronized progesterone. Large-scaled randomized study would be required to confirm our findings.

Purpose: This study was designed to investigate the condition of refractive correction and heterophoria and monocular pupillary distance on myopic elementary school children wearing glasses in Gwangju city. Methods: Subjective refraction and objective refraction were examined after investigating heterophoria and monocular pupillary distance on 145 (290eye) elementary school children wearing myopia-corrected glasses. Results: 1. Anisometropia > 2.00 D was present in 4 children (3%). 2. 9 anisometropia (47%) were present in 19 undercorrected visual acuity boy wearers. and 16 anisometropia (64%) were present in 25 undercorrected visual acuity girl wearers. 3. Among the 67 myopic glasses boy wearers, the distance between optical centers was coincided with the pupillary distance in 30% (Oculus Uterque), and discrepant in 70% (Oculus Uterque). Among the 78 myopic glasses girl wearers, the distance between optical centers was coincided with the pupillary distance in 23% (Oculus Uterque), and discrepant in 77% (Oculus Uterque). The mean optical center distance was longer than the pupillary distance on both boy and girl wearers 4. The result of measured heterophoria revealed 14% for orthophoria, 63% for exophoria, 23% for esophoria at far distance and 10% for orthophoria, 76% for exophoria, 14% for esophoria at near distance. Conclusions: Correct refractive test and monocular pupillary distance must be examined because incorrect refractive test and pupillary distance induce asthenopia and heterophoria.

People begin to recognize sexual orientation or gender identity in adolescence, and adolescents frequently use an accessible and anonymous anonymity knowledge retrieval community to explore sensitive health information about gender. This study attempted to observe their information search behavior based on questions and answers about adolescents' gender identity in the knowledge retrieval community. First, we wanted to examine their information needs and to investigate what factors they preferred to answer by comparing the characteristics of the answers adopted with the non-adopted answers among the answers provided in the questions they shared. To this end, Naver, Korea's representative knowledge search community. In Knowledge-iN, a total of 358 sets of data were analyzed, consisting of responses adopted over three years from January 2016 to December 2018. As a result, adolescents with concerns about gender identity demanded information about definition or confusion about gender identity. In the responses adopted by the users, the factors that gave empathy and positive feelings were higher than those that were not adopted, whereas the negative responses were higher in the unaccepted answers. This study is meaningful in that it analyzes the information needs and information search behaviors of adolescents with no established gender identity, expands the discussion in the information search field, and confirms cognitive and emotional models for information evaluation of health information users. Also, based on the research results, we propose practical implications for effective information services on gender identity that social media should provide to young people.

Lee, Je-ma proposed ways like Chehyungkisang to judge each constitution, so, on the basis of this, we can judge constitution in various ways. Such a theory is based on behavior determinism's way of thinking of Lee, Je-ma. We can know this that form is not recognized as an object reflecting image, but a subjective concept from Tukyonyodun, Yimokbiku(ears, eyes, nose and mouth), Hameokjebok of Sungmyong Theory. Lee, Je-ma thought each part of human body has not only physical function but also complex temperative function. Putting this consideration and Jangbu Theory describing human body directly, together, it can be said that these all have an established theory on Chehyungkisang of constitution judgement. Thus, the following hypotheses are given. From Sadan Theory and Hwakchung Theory, strength of Jangbu of Sasangin is Pe>Bi>Shin>Kan in Taeyangin and Bi>Pe>Kan>Shin in Soyangin and Kan>Shin>Bi>Pe> in Taeumin and Shin>Kan>Pe>Bi in Soumin. The concept of Shinkihyuljung is related with creation of form and spirit of each Jangkuk and Aenoheerak(sorrow, anger, joy, pleasure). From this viewpoint, Sasangin can be classified into; Taeyangin into Shinkijunghyul type, Taeumin into Hyuljungkishin type, Soumin into Junghyuishinki type. Introduced a fixed way to explain of each constitution according to this strength relationship. I hope more lively discussions on Constitutional Medicine will be continued based on this attempt.

For the distribution of fresh produce, the thermoelectric cooling system combined with thermo electric materials (TEM) and phase change material (PCM) was studied. The PCM used this study was produced by in-situ polymerization technology which referred microencapsulation of hydrocarbon (n-tetradecane and n-hexadecane). In this study, quality characteristics of bell peppers in thermoelectric cooling system combined with TEM and PCM were analyzed and control was placed in an EPS (expanded polystyrene) box. As a result of quality characteristics analysis, weight of bell peppers decreased and moisture content of bell peppers was 90.96~94.43% during storage. Vitamin C content of bell pepper decreased during storage and reduction ratio of control was higher than that of BPT-5 treatment(bell pepper in thermoelectric cooling system with PCM which is kept the temperature at $5^{\circ}C$). The result of color value, on 21 day, ${\Delta}E$ value of BPT-5 treatment was 5.05 while that of control was 41.8. On 21 day, total bacteria count of BPT-5 treated bell pepper shown less than that of control. In conclusion, it suggested that the thermoelectric cooling system combined with PCM improved quality of fresh produce during transportation and storage.

This study was carried out to determine plant growth and bolting characteristics of Angelica gigas. Three varieties and/or lines Manchu bolting resistant variety, AGJ90-1 medium type line, and bolting Jinbu local were used for field trial in Suwon. FIve different transplanting times were applied on March 25, April 5, April 15, April 25, and May 5th. Survival rate was decreased by the delayed transplantation and it affected after April 25th respectively. Plant growth by the early transplantation showed the best growth during the beginning stage and recognized signifiquence but not by the late transplantation. Bolting rate revealed severe different by the variety and line, it ranged from $10{\sim}8.1%$ of Manchu, $5.9{\sim}20.3%$ of AGJ90-1, and $58.5{\sim}74.6%$ of Jinbu local clearly. By the treatment of transplantation time bolting rate was different, early plantation showed high bolting rate compare to the late plantation from the all of tested variety and lines. Bolting response according to the transplanting time, bolting resistant variety showed insensibility and boling line showed sensitive response. In Manchu root yield was best when planted on April 5th as 389 kg /10a, in case of AGJ90-1 was determined 377 kg/10a when planted on April 15th, and Jinbu local root yield was showed 133 kg/10a planted on April 25.
