朴良門,趙南棋,韓在現,姜奉均 濟州大學校亞熱帶農業硏究所 1996 亞熱帶農業硏究 Vol.13 No.-
summaryThis experiment was carried out investigate the influence on different of planting density on agronomic and yield characters of cheju native soybean.The results are summarized as follows ;1. The narrower planting space, the higher stem length and the broader the planting space,the shorter, but stem diameter, number of nodes main stem and number of branches tended to be opposed. 2. Number of pods, dry stem weight and weight of 100 seeds were increased as the broader the planting space. 3. Seed yield was greatest in 341kg/10a than other planting space. 4. Dry stem weight was positively correlated with stem diameter and number of branches, and stem diameter was positively correlated with number of pods per plant, number of branches. But Stem length was negatively correlated with dry stem weight, weight of 100 seeds and stem diameter. Seed yield was negatively correlated with dry stem weight and weight of 100 seeds.

송요한,김문현,김형섭,김재곤,백병주 大韓小兒齒科學會 1998 大韓小兒齒科學會誌 Vol.25 No.2
The Papillon-Lefevre Syndrome(PLS), a disease with autosomal recessive inheritance, is characterized by diffuse hyperkeratosis of the palms and soles, mostly prepubertal periodontitis and premature loss of primary and permanent dentition. The etiology of the destruction of periodontal tissues has not been completely clarified. In recent years, two main factors are suggested to be responsible for tooth loss : firstly, the presence of gram negative microorganisms in the periodontal pockets of the patients. The other factor suggested is cellular deficiency in chemotaxic and phagocytic function of neutrophylic granulocytes. Resent data suggestes that mechanical debridement in conjunction with antibiotic therapy may be successful in periodontal management of Papillon-Lefevre Syndrome, particularly if administered early. In this study, a Papillon-lefevre syndrome patient was studied clinically, radiologically, histopathologically and microbiologically. 5 years female patient with gingival swelling and destruction of periodontal structure on the whole dentition were examined and palmar and plantar hyperkeratosis were can be seen. On microbiological analysis, Actinobacillus actino-mycetemcomitans was performed. Concurrently, the children recieved extraction of maxillary anterior teeth and construction of removable prosthetis. The combination of professional oral hygiene care and antibiotic therapy improved the dermatologic and peridontal condition.

약물의 폐 전달을 위한 염화 벤제토늄 기반 리포좀의 제조 및 평가
문용현, 유소열, 안지선, 이한솔, 김혜림, 이은주, 이재영 충남대학교 약학대학 의약품개발연구소 2021 藥學論文集 Vol.36 No.-
Benzethonium chloride-containing egg phosphatidylcholine-based liposomes (BC/EPC-LIPOs) were developed for lung-targeted drug delivery. BC/EPC-LIPOs were fabricated via thin-film hydration method with various BC-to-EPC molar ratios of 1:4 (F1), 1:1 (F2), and 4:1 (F3). Cyanine5.5 (Cy5.5) was loaded as a fluorescent probe for the biodistribution study during the film-forming step. BC/EPC-LIPOs were evaluated by using dynamic light scattering analysis, where the mean diameter and zeta-potential values of F1, F2, and F3 were observed to be 69.5 ± 3.1 nm and 50.06 ± 1.00 mV, 59.0 ± 2.3 nm and 51.30 ± 2.98 mV, and 694.2 ± 243.3 nm and 55.01 ± 3.16 mV, respectively. To evaluate the lung distribution efficiency of the developed liposomes, F1 and F2, which possess suitable particle sizes for the intravenous administration, were injected into the tail vein of ICR mice. At 6 h post-injection, the lung, liver, kidney, heart, spleen, and brain were dissected, and the radiant efficiency (RE) values of the or- gans were measured using the near-infrared fluorescence imaging method. The lung RE value of F2 was 1.69-fold higher than that of F1, indicating a more efficient lung targetability of F2. This phenomenon can be attributed to the higher content of BC in F2 than F1. Considering the lung-targetability, as well as the biocompatible natures of BC and EPC, the developed BC/EPC-LIPOs can be used as an efficient lung-targeted drug delivery system.

산전 태아사망 환자에서의 Mycoplasma hominis와 Viridans streptococcus감염 1예
김윤숙,문성택,전섭,김종수,최승도,선우재근,배동한 순천향의학연구소 2007 Journal of Soonchunhyang Medical Science Vol.13 No.1
Mycoplasma hominis was isolated from a Bartholin's gland abscess 70 years ago, and ureaplasmas were isolated from the genital tract about 20 years later. Subsequently, reports incriminating mycoplasmas in the known adverse outcomes of pregnancy have been reported. Without doubt these genital mycoplasmas are able to invoke an inflammatory response and take part in the cascade of events that culminate in preterm birth. Amniotic fluid infection results in considerable pregnancy wastage in the pregnancy. In these cases Gram-positive organisms, especially group B streptococcus and Streptococcus viridans were the most common pathogens isolated. In our case, the patient has fever and vaginal discharge at 14+4 weeks gestation and two days after intrauterine fetal death was seen. The vaginal culture and sensitivity shown Mycoplasma hominis and Vihdans streptococcus. We experienced a case of Mycoplasma hominis and Viridans streptococcus infection in a patient with intrautehne fetal death and report with a brief review of literatures.

With the assumption that the desirable leisure activities are required to prevant the high school students' misconducts and to tester their sound moral character, this study investigated and compared the present state of the high school students' leisure activities. The subjects of this investigation are 774 students attending boys' and girls' high schools located in seoul and one south-western rural area in korea. The comparisons are largely made on two aspects; one of them is regional comparision, the other is with respect to the gender of subjects. The conclusions made in the this study are the followings: 1.The Preferred Type of Leisure Activities. The favorate leisure activities which the boy students and the girl students in seoul area choose are 'sports'(90 boy students,45.45%), and 'watching films performances and music listening'(116 girl student 61.05%) respectively. The boys and girls living in the rural area are shown to prefer 'sports'(58 boy Student.,30.20%), and 'watching fialms, performances and music listening'(91 girl students 46.90%) respectively. 2.The Reason of Leisure Activity Participation The main reason why the boy students in seoul take part in the leisure activities is 'to reduce the stress from the routines'(68 students 34.34%). The girl students of the same area participate in the leisure activities mainly becouse they want 'to got refreshmant and rest'(86 students,45.26%). In the case of rural area boy students, the main reason why they take participate in the leisure activities is identical to that of the boy students 'to reduce the stress'(83 students 43.22%). For the girl students of the rural area. however, 'self-contantment and security of life'(66 girl students,34.02%) are presented as the main reason of taking part in the leisure activities. X2- verifacation shown that the difference is greatly significant for the girl students (p<.001). 3.Perceived Possibility of Leisure Activity Participation The values of the perceived possibility of leisure activity paricipation are 3.24 ±0.57, and 3.08 ±0.49 respectively for the boy and girl students in seoul, and 3.28±0.61, and 2.98±0.47 respectively for the boys and girls in the rural area. t-verifacation by the residental area shown a signiticant difference for the boy students (p<.001) and girl students (p<.01) 4.Degree of Immersion into Leisure Activities The degree of immersion into leisure activities are 2.81 ± 1.01 for the boys in seoul, and 3.06± 1.01, for the girls in the same district. Those for the boys and girls living in the rural area are 2.97± 1.06 and 3.25±0.61, respectively. t-verifacation shown no significant difference both from the aspect of region. 5.Degree of Satisfaction with the Leisure Activities The values of satisfaction with the students' leisure activities 3.43 ±0.55 and 3.27 ±0.58 respectively for the boy students and girl students living in seoul. The values for the boys and girls in the rural area are 3-34 ±0.50, and 3.07 ±0.29 repectively. t-verifacation by the residental area shown a significant difference for the girl students(p<.01). From this study, We come to fond out that the high school students investigeted in this study take part in variouse kind of leisure activities. But the 'qualty' of the leisure activities is more imports then the 'quantity', that is it is required that we give more opportunities for the students to take part in the sound and productive leisure activities, while reducing the change of the students' participating in the degenerated and consumptive leisure activities. Bosides, the 'enterance examination-oriented' educational environments of the present korea is giving the students much more stress than even before, and the insufficient facilities and space make most of the students feel it very invonvenient to take part in the leisure activities freely. Accordingly, to save the students from the stress resulting from study and neverending examinations, and to give them refreshment and rest, it is required that we shoul lead them to more sound and productive leisure activities(such as watching sports games, taking trips and sight-seeing), and also provide them more space and facilities where they enjoy more varied kinds of leisure activities. In short, to encourage the juveniles to take part in the sound and productive leisure activities, more drastic investment, the recognition of the importance activity, and consisting development of variouse and sound leisure activity programs are urgently needed.
