According to statistics, it is shown that domestic SMEs rely on bank loans for the majority of fund procurement. From financial information shortage (Thin file) that does not provide information necessary for credit evaluation from banks such as financial statements. In order to overcome these problems, recently, in alternative finance such as P2P, using differentiated information such as demographics, trading information and the like utilizing Fintech instead of existing financial information, small funds A new credit evaluation method has been expanding to provide SMEs with small amounts of money. In this paradigm of environmental change, in this research, credit evaluation which can expand fund supply to SMEs by utilizing big data based on trade area information such as sales fluctuation, location conditions etc. In this research, we try to find such a solution. By analyzing empirically the big data generated in the trade area, we verify the effectiveness as a credit evaluation factor and try to derive the main parameters necessary for the business performance evaluation of the founder of SMEs. In this research, for 17,116 material businesses in Seoul City that operate the service industry from 2009 to February 2018, we collect trade area information generated for each business location from Big Data specialized company NICE Zini Data Co., Ltd.. We collected and analyzed the data on the locations and commercial areas of the facilities that were difficult to obtain from SMEs and analyzed the data that affected the Corporate financial Distress. It is possible to refer to the variable of the existing unused big data and to confirm the possibility of utilizing it for efficient financial support for SMEs, This is to ensure that commercial lenders, even in general commercial banks, are made to be more prominent in one sector of the financing of SMEs. In this research, it is not the traditional financial information about raising fund of SMEs who have basically the problem of information asymmetry, but a trade area analysis variable is derived, and this variable is evaluated by credit evaluation There is differentiation of research in that it verified through analysis of big data from Trading-area whether or not there is an effect on.

Yams (Dioscorea spp), which are edible or medicinal tuber crops, are a important crop in South Korea. Yams require a high level of soil fertility. The various cultural practices such as fertilizing and plowing were tested for marketable tuber production in Chinese yam (Dioscorea opposita). Tuber yield was also affected by organic matters in soil. Application higher level of organic matters result in increased each tuber weight and tuber yield per unit area. The nutrient absorption quantity of the plant such as nitrogen, phosphoric acid, calcium and potassium was increased from 100~120 days after planting, which time to begin tuber enlargement. The tuber yield was increased when the fertilization increased in quantity. Total yield and marketable ratio were the highest in 31~32 kg/10a of nitrogen fertilizer. From above result, income become larger with increase of marketable yield and quality improvement at 63% (27 kg/10a) level of conventional N fertilization (43 kg/10a). The tuber yield was not significantly different between with in various application level of potash fertilizer. Tuber size and weight decreased accordingly to decreased fertilizing level, so the rates of small tubers increased greatly at cultivation without chemical fertilizer. In considering the accumulation rates of allantoin in Chinese yam tubers, the apt harvest season was after October. The allantoin quantity of it was not influenced with nitrogen fertilizing. Moreover it was advantageous with decrease of chemical fertilizer and appropriate fertilizing in soil environment protection. Commercial tuber's number and yield were increased in trenching before planting with trencher compared with rotavating with tractor.

Purpose : To evaluate the factors which contribute to the time of the first stool and the first urine passage. Methods : We retrospectively reviewed a chart of 1,221 infants ${\geq}34$ weeks of gestational age admitted to the normal newborn nursery of Il Sin Christian Hospital, Busan, from November 2004 to April 2005. We compared the time to first stool and urine according to maternal factors(maternal age, parity, mode of delivery, meconium-stained amniotic fluid, and maternal diabetes) and infant factors (gender, Apgar score, gestational age, type of feeding during first 24 hours, age at the first feeding, number of feeds during the first 12 hours and age at discharge). Results : In total, 95.3 percent of our infants had passed their first stool by 24 hours and 99.8 percent of them had a stool by 36 hours. A total of 95.8 percent of our infants had passed urine by 24 hours of age and 98.3 percent of them by 36 hours. Comparing preterm and term infants, the time to first urine is $6.5{\pm}5.8$ hours and $12.1{\pm}6.6$ hours, respectively(P=0.000). The time to first stool is $20.7{\pm}13.5$ hours and $10.0{\pm}6.3$ hours, respectively(P=0.000) Early-fed infants were significantly earlier in time to first urine(P=0.023) and first stool(P=0.012). There was no statistically significant relationship between the number of feeds in 0-12 hours, mode of delivery, Apgar score, parity, gender, type of feeding, maternal diabetes and the time of the first urine and first stool. Conclusion : Gestational age, birth weight and age at first feeding were significantly related to the time of the first urine and first stool passage. When there is delayed passage of the first urine and first stool, we should consider close observation of other associated symptoms and other factors previously mentioned, to avoid extensive evaluation and intervention.

331 patients of stage IIb uterine cervix cancer trated by radiation alone at Kosin Medical Center between June 1980 and Dec. 1985 were analysed to determine parameters of radiotherapy associated to disease states. Survival rate was highest among the reported ($82.8{\%}$ for crude and $82.4{\%}$ for disease free survival). Pelvic control rate in 6 weeks after the end of radiotherapy was $93.6{\%}$ in the patients treated with ICR following total pelvic radiation and $71.6{\%}$ with small field additional external irradiation. 5 year survival rate in those who achieved pelvic control was $98.9{\%}$ and $12.9{\%}$ in those who had pelvic failure and/or metastasis after radiation. The survival rate figured maximal $88.5{\%}$ with dosage of $7500{\~}8500$ cGy to point A with acceptable incidence of complications ($4.9{\%}$) but without increasing survival above it and minimal $74.1{\%}$ with dosage of less than 6500 cGy. The treatment failure was counted $18.7{\%}$ (62 of 331 patients): Local failure $72.6{\%}$ (45 of 62 patients), locoregional failure $3.2{\%}$ (2 of 62 patients) and distant failure $24{\%}$ (15 of 62 patients). Late complications were found in 50 patients ($15.1{\%}$) and $42{\%}$ of them was rectal bleeding and stenosis. The dose of 8500 cGy to point A was found to be critical for complication and $70{\%}$ of complications occurred above it and was more serious one such as fistula. Rectal complications were developed above rectal dose 6500 cGy and bladder complication above bladder dose 7500 cGy. Major cause of death was cachexia due to locoregional failure ($73.7{\%}$ of death), next was due to metastasis to lung, liver and bone, and only 3 patients died of complication of intestinal perforations and obstruction. In conclusion higher external radiation dose for a bulky uterine cervix and barrel shaped uterus was essential for local control.

The advantages of mitral valve reconstruction have been well established and so mitral valve reconstruction is now considered as the procedure of choice to correct mitral valve disease. This is the report of intermediate-term results of 38 cases that performed mitral valve reconstruction for valve insufficiency(the total number of mitral valve reconstruction were 49 cases, but 11 cases that performed mitral valve replacement due to incomplete reconstruction were excluded). Material and Method : From March 1991 to March 2001, 38 patients underwent mitral valve repair due to mitral valve regurgitation with or without stenosis. Mean age was 47.6$\pm$14.7 years(range 15 to 70 years) : 11 were men and 27 were women. The causes of mitral valve regurgitation were degenerative in 14, rheumatic in 21, infective in 2 and the other was congenital. Result : According to the Carpentier's pathologic classification of mitral valve regurgitation, 3 were type 1 , 16 were type II and 19 were type III. Surgical procedures were annuloplasty 15, commissurotomy 19, leaflet resection and annular plication 9, chordae shortening 11, chordae transfer 5, new chordae formation 2, papillary muscle splitting 2 and vegetectomy 2. These procedures were combined in most patients. There were 2 early death and the causes of death were respiratory failure, renal failure and sepsis. There was no late death. Valve replacement was done in 6 patients after repair due to valve insufficiency or stenosis 3 weeks, 1, 3, 51, 69, 84months later respectively. These patients have been followed up from 1 to 116 months(mean 43.0 months). The mean functional class(NYHA) was 2.36 pre-operatively and improved to 1.70. Conclusion : In most cases of mitral valve regurgitation, mitral valve reconstruction when technically feasible is effective operation that can achieve stable functional results and low surgical and late mortality.

Objective : Postpartum depression(PPD) was known to be caused by many factors including various psychosocial risk factors. This study was performed to identify the psychosocial risk factors for ppd, preliminarily in Korea. Methods : A group of 119 postpartum women, each of whom was at 6 to 8 weeks after delivery was identified at the time when they visited to the child health clinic or postnatal check-up clinic. The risk factors were surveyed by the self-reported questionnaire. The items of questionnaire were consisted of known risk factors in other studies and other possible stress-related factors. PPD was assessed by the Edinburgh Postnatal Depression Scale(EPDS) and the degree of postpartum depression was determined by its score. Results : 16 women(13.45%) in the high risk group were diagnosed as PPD among the 119 women. Risk factors including past experience of depressive symptoms and low level of marital satisfaction were founded more frequently in women in the high risk group than in the low risk group. The score of EPDS was significantly high in the group who experienced depressive symptoms in the past, anxiety or depression during pregnancy, stressful life event during the period of recent pregnancy and postpartum, and who had low level of marital satisfaction. There was a positive correlation between age and the score of EPDS. However, the postpartum depressive symptoms were not influenced by the level of education, job, retirement due to pregnancy and delivery, wanted or unwanted pregnancy, delivery method, feeding method, the hospitalization of infant, expected and real gender of infant. Conclusion : These results suggest that PPD is quite frequent at postpartum period. Various risk factors contribute to the development of PPD. If clinicians pay attention to the risk factors of PPD and give appropriate psychiatric intervention to the mothers during pregnancy and postpartum, it will be easy for the clinicians to recognize and treat PPD in the early stage.

Purpose: In patients with meniscal tear with degenerative arthritis, controversy remains as to whether arthroscopic menisectomy is worthwhile or not. The purpose of this study was to evaluate the effect of arthroscopic medial meniscectomy in degenerative arthritis of the knee with meniscal tear. We also intended to identify pertinent indications and risk factors. Materials and Methods: 287 patients underwent arthroscopic medial meniscectomy from 2006 to 2008; 103 patients who had Kellgren-Lawrence grade II, III arthritis of the knee, were over 50 years old, and had minimum 1 year follow-up, were analyzed in this study. Clinical assessment was performed retrospectively using the arthroscopic surgery database, medical records, questionnires and interviews. Assessment included visual analogue scale (VAS) scores and Lysholm scores. Results: The mean Lysholm score increased from 69 to 85 after surgery. The mean VAS score improved from 7 to 3.1 after surgery. Kellgren-Lawrence grade II group and group with trauma history showed significant improvement of pain and function compared with grade III and group without trauma history. Outerbridge grade I showed significantly more improvement of pain than grade III and IV. Multiple regression analysis showed that trauma history and Outerbridge grade affect the improvement of Lysholm score. Conclusion: In one year follow-up, arthroscopic medial menisectomy can improve pain and function of patients in Kellgren-Lawrence grade II, III degenerative arthritis of the knee. We could expect good results especially in group with low Kellgren-Lawrence grade, trauma history, and mild articular cartilage lesion.

Various susceptibility tests have been used to determine minimal inhibition concentration(MIC) of dermatophytes. They have limitations to apply practically because they need long time to determine MIC. Authors examined MIC of T. rubrum to ketoconazole and itraconazole using 96-well microplate and 24-well macroplate by method of Granade and Artis and tried to check the possibility of this method on clinical application. Nine strains of T. rubrum from patients with dermatophytosis were used. Evaluations of the factors affecting MIC were also tried. The results were as follows. 1. Effect of inoculation density on determination time and MIC : Determination of MIC were possible in 4th days after inoculation at higher inoculation density Caborbance 2.0, 1.0) compared to 6th days at lower inoculation density(absorbance 0.5, 0.25). 2. Effect of incubation temperature on MIC : When incubating at $37^{\circ}C$, MIC were below 0.006-$0.04{\mu}g/ml$ to ketokckonazole and below 0.006-$0.04{\mu}g/ml$ to itraconazole while at $25^{\circ}C$ 0.08-$5.68{\mu}g/ml$ to ketoconazole and 0.006-$0.71{\mu}g/ml$ to itraconazole. Significant reduction of MIC was observed at $37^{\circ}C$ compared to $25^{\circ}C$. 3. Effect of container size on determination time and MIC : When incubating in 96-well microplate and 24-well macroplate, determination of MIC was possible in 4th to 6th days after inoculation in broth-containig 96-well microplate compared to 8th to 12th days in broth-containing 24-well macroplate. But no difference in MIC was observed between different container size. 4. Effect of media on MIC : When using broth as media, MIC were below 0.006-$5.68{\mu}g/ml$ to ketoconazole, below 0.006-$0.36{\mu}g/ml$ to itraconazole in broth-containg 24-well macroplate. When using agar as media, MIC were below 0.006-$5.68{\mu}g/ml$ to ketoconzole, below 0.006-$5.68{\mu}g/ml$ to intraconzole in agar-containing 24-well macroplate. There was slight increase of MIC with agar media compared to broth media. 5. These findings confirm that determination of MIC of dermatophtes by method of Granade and Artis is fast and simple technique for antifungal susceptibility test.

This study was conducted to investigate a potential of Yellow poplar (Liriodendron tulipifera L.) as a raw material for the manufacturing of particleboard (PB) and oriented strandboard (OSB). PB panels were prepared at the parameters of $0.7g/cm^3$ density, 15 mm thickness, three-layer, $E_1$ grade urea-formaldehyde (UF) resin, emulsion wax, and hardener. OSB panels were manufactured with a density of $0.65g/cm^3$, thickness of 10 mm, and $E_1$ grade of UF resin. Particle size of the face layer of PB was 20~80 mesh with 7~9% moisture content (MC), while that of core-layer was 3~20 mesh with 3~5% MC, which was similar to the production condition of commercial PB. As a result, the manufactured PB panels with 15.8 mm thickness, $0.7g/cm^3$ density, and 5.8% MC satisfied the requirement of bending strength of 15 type PB of Korean Industrial Standard (KS F 3104). Both internal bonding (IB) strength and surface screw withdrawal resistance also satisfied the requirement of 18 type PB of the standard. But, the edge screw withdrawal resistance satisfied the requirement of 15 type PB of the standard. These differences in properties could be due to the slenderness ratio of raw particles. In case of OSB panels with 10.7 mm thickness, $0.68g/cm^3$ density, and 5.8% MC satisfied all the requirements of bending strength, screw withdrawal resistance, and IB strength of 18 type PB of the standard. These results suggest that Yellow poplar wood has a good potential as a raw material for the production of PB and OSB.
