Purpose: To evaluate the correlation between the fibrillar pattern of the Achilles tendon on ultrasonography (US) and functional outcomes in patients who underwent open tendon repair after Achilles tendon rupture. Materials and Methods: Data of 44 patients who had been subjected to US at least 6 months after repair, during the period between July 2012 and July 2019 were reviewed. Those with bilateral tendon rupture, re-rupture, open injury, and chronic or insertional rupture, were excluded from the review. We divided them into two groups, the homogenous group (HoP) and the heterogenous group (HeP) based on the fibrillar pattern on US. We also divided the HoP into linear and wavy subgroups, and the HeP into no hypoechoic lesion and hypoechoic lesion subgroups. The rupture type of the Achilles tendon, radiographic factors including US and magnetic resonance images, patient-related, surgical factors, and clinical results at the last visit after repair were assessed retrospectively. Results: The tendon thickness was 11.4±1.7 mm in the HoP, and 14.5±3.0 mm in the HeP (p<0.001). A shredded pattern was observed in 17 cases (65.4%) in the HoP, and in 17 cases (94.4%) in the HeP (p=0.031). The mean value of the number of sutures used was 8.9±3.05 in the HoP and 11.39±1.75 in the HeP (p=0.001). The mean value of the difference in calf circumference was 0.9±0.67 cm in the HoP and 1.36±0.71 cm in the HeP (p=0.037). There were no statistically significant differences in the fibrillar patterns and patient-related factors. Conclusion: The fibrillar pattern observed after repair was correlated with the functional outcome and showed a significant relationship with the rupture pattern and the number of sutures used. Therefore, we suggest a careful individualized postoperative rehabilitation protocol to maximize functional outcomes by referring to the fibrillar pattern in US, especially in shredded ruptures.

The objectives of this study were to i) investigate genetic performance for linear type traits of individual Holstein dairy cows, especially focusing on comparative traits, and to estimate genetic variances for these traits using actual data, and ii) compare genetic performance and improvement of progeny by birth country of the cows. Linear type traits defined with five comparative traits on this study were general stature composite (GSC), dairy capacity composite (DCC), body size composite (BSC), foot and leg composite (FLC), and udder composite (UDC). These traits were scored from 1 to 6 with 1 = poor, 2 = fair, 3 = good, 4 = good plus, 5 = very good and 6 = excellent. Final scores (FS) were also included in this study. Data used was collected from the years 2000 to 2004 by the Korea Animal Improvement Association (KAIA). Only data of more than five tested cows by herd appraisal date and by sires having more than ten daughters were included to increase the reliability of the data analyses. A total of 30,204 records of the selected traits, which was collected from 26,701 individuals having pedigree information were used. Herd appraisal date, year of age, lactation stage (grouped by month), and time lagged for milking (in hours) were assumed as fixed effects on the model. Animal additive genetic effects considering pedigree relationship and residual errors were assumed with random effects. Year of age at appraisal date was classified from one to nine years of age, assigning the value of nine years of age for animals that were greater than or equal to nine years of age. From our results, the estimate for heritability was 0.463, 0.346, 0.473, 0.290, and 0.430 on GSC, DCC, BSC, FLC and UDC, respectively. The estimate for FS heritability was 0.539. The greatest breeding values for GSC were estimated for Canada, with the breeding values for American lines increasing for 10 years starting in 1989 but tending to decrease after that until 2004. For DCC, the breeding values for American and Canadian lines showed similar patterns until 1999, after which the breeding values for the American lines declined sharply. For BSC, data from Korea, Canada and the USA followed similar trends overall except when the breeding values of the American lines decreased starting in 1999. Overall, the methods used to evaluate genetic performance in this study were acceptable and allowed for the discovery of differences by country of genetic origin, likely due in part to the American use of selection indexes based primarily on milk yield traits until methods for evaluating other traits began to emerge.

철화(鐵畵) '성(成)' 명청자(銘靑瓷)는 전라남도(全羅南道) 강진군(康津郡) 대구면(大口面) 사당리(沙堂里) 7호 가마터에서만 출토되는 특징적 청자로 붓을 이용하여 굽안바닥 중앙에 명문(銘文)을 쓰고 있다. 명문이 눈에 잘 띄지 않은 곳에 표기되어 있으며, 필체가 다양하여 생산에 여러 사람이 참여하였음을 알 수 있어 제작자보다는 공방(工房)을 표기하였던 것으로 추정된다. 또한 유약(釉藥)과 태토(胎土), 기형(器形), 문양(文樣), 번법(燔法) 등 품격(品格)이 동일(同一)하여 같은 제작기법을 사용하여 같은 시기에 제작되었음을 쉽게 알 수 있다. 기종(器種)은 ${\Box}$과 대${\Box}$(大), ${\Box}$시(匙), 잔(盞), 합(盒), 병(甁) 등 일상(日常) 생활용기(生活容器)가 중심을 이루고 있다. 시문기법(施文技法)은 음각(陰刻)과 상감(象嵌)보다 압출양각(壓出陽刻) 기법을 특히 선호하였으며, 음각보다 상감의 예가 적어 이 시기 상감기법이 보편화되지 않았음을 알 수 있다. 문양은 국화문(菊花文)과 모란문(牡丹文), 앵무문(鸚鵡文), 연판문(蓮瓣文), 연당초문(蓮唐草文) 등으로 권위나 위엄의 의미를 갖는 특별한 문양은 확인되지 않는다. 굽은 합과 접시의 일부를 제외하고 대부분 'U'자형으로 성형하였으며, 번법(燔法)은 내화토(耐火土) 비짐이 일부 있으나 전면(全面) 시유(施釉) 후 굽 안바닥 3~4 곳에 규석(硅石)을 받쳐 굽고 있다. 생산시기(生産時期)는 현재 사당리 7호 가마터 이외의 유적에서는 확인되지 않아 유사한 성격을 갖는 유적 출토품과의 비교를 통해 13세기(世紀) 2/4분기(分期)에 생산되었음을 알 수 있었다. 그리고 고품격의 양질청자에 비해 상대적으로 품질이 떨어지는 일반적인 양질청자가 중심을 이루고 있어 왕실(王室) 등의 최상류층보다 한 단계 낮은 계층에 공급되었던 것으로 추정된다. '성(成)' 명청자(銘靑瓷)는 그동안 전성기(全盛期) 음 양각 기법의 청자를 모두 12세기대로 편년하면서 발생하였던 13세기 전반의 공백을 보완할 수 있는 편년 자료로 그 중요성이 매우 크다고 하겠다.

Objectives : The purpose of this study is to inquire into the effect of different concentrations of bee venom pharmacopuncture to inhibit genesis of pro-inflammatory cytokines and to inhibit nuclear factor (NF)-${\kappa}B$ activation on type II collagen induced arthritis. Methods : The experiment was divided into category of the normal group (NOR)-no treated group, control group (CON)-CIA (collagen induced arthritis) induced group, and 4,000 : 1 bee venom group (BV-L)- 4000:1 bee venom pharmacopuncture treated group after CIA, and 2000:1 bee venom group (BV-H)- 2,000 : 1 Bee venom pharmacopuncture treated group after CIA. RA was induced in the mice via injecting $50{\mu}{\ell}$ C II mixed CFA. The bee venom pharmacopuncture was applied on $ST_{35}$ for 19 days from the 3rd day of RA inducement. To research the effect on the expression of IKK ($I{\kappa}B$ kinase), iNOS (inducible nitric oxide synthase) & COX-2 (cyclooxygenase-2) mRNA, RT-PCR was performed on synovial membrane cells from the knee joint of CIA mice. Results : The PMA-induced $I{\kappa}B$ kinase (IKK), inducible nitric oxide synthase (iNOS) and cyclooxygenase -2 (COX-2) mRNA expression were dose-dependantly decreased in bee venom treated with synoviocytes. In mice treated with bee venom pharmacopuncture, foot thickness and the damage of synovial membranes of the joint was lessened, and the activation of RA-related pro-inflammatory cytokines such as MIF, TNF-${\alpha}$ and MMP-9 was significantly decreased. The activation of iNOS and COX-2 was suppressed by the inhibition of NF-${\kappa}B$. In addition, each data was shown that 2,000 : 1 bee venom pharmacopuncture was more effective than 4,000 : 1 bee venom pharmacopuncture. Conclusions : It is speculated that bee venom pharmacopuncture has the therapeutic effect of palliating the damage of the synovial membrane and inflammation on RA by suppressing of NF-${\kappa}B$ activation.

Since Korea disclaimed to open the ports, Korean architecture has met the impetuous transformation. Although there would be various factors of this transformation, the new-coming architecture by missionary seemed to be a significant one, and many researches have been carried out on this theme in diverse viewpoints. However, because these researches have preponderated on the Catholic tradition, it is deficient for clarify the whole history of mission architecture. Therefore, this research has the meaning to enrich the history of Korean modern architecture by making balance. First of all, this paper is focused on the activities of one missionary, Graham Lee. He is a practical missionary at the beginning, his architecture made a critical influence in Korean traditional architecture. Graham Lee was born in Rock Island, Illinois, 1861, and he determined to become a missionary through grown up. He spent his boyhood by working as a plumber for his purpose and studied in a university afterward. Graduating of McComick Theological Seminary, he was nominated as a pioneer of Pyeng Yang Mission Station and set foot in Korea, September of 1892. Since then he started to erect missionary facilities in Pyeng Yang, such as Well House(1898), Pyeng Yang Central Church(1900-1901), Pyeng Yang Academy(1902). These all his works are designed with eclectic style which shows western and Korean traditional style intermingled. This unique characteristic made a profound influence to the Korean mission architecture afterwards. Especially, the L-type plan of Pyeng Yang Central Church, which is first shown by him, is recognized very unique, and this plan type had been spread all over the country. Therefore the L-type plan became the peculiar feature of the early Korean churches. Furthermore, working with Korean carpenters, he taught them new skills of modem buildings. After that, they were expanded out northern part of Korea and took the roles of master builders. According to this expansion, his particular style had got spread and had been settled as a unique eclectic style in Korean modern architecture. In the conclusion, he is evaluated to be a critical pioneer missionary, who left a big influence on the frame work of Korean modern architecture in the transitional times.

This study selected a case study method conforming to qualitative research in order to analyzed how each type of fashion enterprises uses SNS in-side of fashion marketing based on content the researcher monitored and selected from the Facebook website for each enterprise. The standard to select fashion brands in this study is a graded list made based on ranking 5 analysis sites on social media (Socialbakers, socialDigm, Pulse K, BigFoot9, L2). The researcher sorted and then analyzed 2 brands that have many fan joiners and followers among fashion brands that were ranked top of the graded list, work in Facebook animatedly, and had representativeness in each type (SPA, Sports Brands). The study was conducted from January 2013 to March 2013, and the index of Facebook consisted of 3 kinds of elements (comment, like, and share). Each numerical value was counted to decide the monthly ranking. Content analysis was divided into public relations about brand, public relations about products, and customer participation and activities; consequently, the researcher investigated which content was post conforming to the ranking. The study analyzed the analysis results of each brand derived through the method of study compared to other brands. The results are as follows. In case of SPA brands, the category accounting for high rank in index analysis are public relation events to attract customer attention and products and offering information. The results of the monthly trend about whole post category were also similarly analyzed so the promotion goal that the brand wants to seek in priority coincides with the customer compliance rate. Next, in the case of sports brand, public relations for products offering information, event for arousing customer concern, and participation activities accounted for a high rank in the index analysis and posted the most in the analysis of the monthly trend for whole post category. The researcher came to understand that the direction of content for brands shown through Facebook coincides with customer sympathy.

우리나라에서 가장 흔히 발생하는 산사태는 쇄설성유동(debris flow)이며 이는 집중호우 시기인 6월-8월 사이에 대부분 발생한다. 조사통계에 의하면 2일간의 강우량이 200mm 이상일 때 발생하기 시작한다. 이들은 산사면의 노두 발달이 양호한 지역에서는 발생하지 않으면 노두가 없는 지역에서만 발생한다. 초기에는 전이형슬라이드(translational slide)로 시작되며 파괴물질이 산사면의 계곡으로 유동되면서 쇄설성유동으로 전이된다. 쇄설성유동의 원인이 되고있는 전이형 슬라이드의 발생인자는 강우와 인위적 조건을 제외하면 암석의 종류, 지형고도, 사면경사, 입도분표, 투수계수, 건조밀도, 공극율 등이다. 이들 발생인자들의 통계처리, 특히 로지스틱 회귀분석에 의하여 인자들의 정량적 가중치를 구하여 산사태 발생 확률을 정량화 하였다. 암반포행(rock mass creep)은 대부분 경상계 퇴적암지역에서 발생되면 직접원인은 거의 사면 하단 부의 절토 때문이다. 전단전이는 적은 편으로 1m 내외이나 포행암반의 규모가 크기 때문에 매우 위험하다. 칠곡, 부산 황룡산 터널입구, 사천 산사태 등이 이 범주에 속한다. 포행의 원인이 되는 상부 전단대는 대부분 주변에 발달되어있는 단층이나 대규모 전달절리와 연과되어 있어 사면설계 조사시 지질구조에 주의를 요한다. 회전형 슬라이드(rotational slide)는 토양층이 두껍거나 기반암이 심히 풍화된 연약층에서 발생하여 이들도 흔히 사면 하단부의 절토와 연관되어있다. 이 산사태는 원호 또는 반원호형으？ 진행되는 특징이 있으며 우리나라에서는 제 3기 응회암 지역이 취약하다. 이는 화산재와 화산쇄설 물질이 흔재된 제3기 응회암의 절리가 매우 잘 발달되어있어 팽윤과 흡수율이 높고 이로 인하여 심부까지 풍화에 취약하기 때문으로 경주 산사태와 포함-구릉포간 국도면의 산사태가 이 종류의 산사태에 속한다.

Purpose: Many studies reported anatomy of posterior tibial artery perforator. But, it is not easy to use this flap in clinical case. Methods: Authors performed cadaver dissection on 26 legs from 13 cadavers and identified the number, location, type, length and diameter of perforator. Based on anatomic study, posterior tibial artery perforator flap was performed on 3 clinical cases. Results: The perforator was found on a line drawn from the medial boarder of central patella to posterior boarder of medial malleolus. The main perforator which was longer and greater caliber than others was found was found 13 to 17cm distant from medial boarder of central patella in 23 of 26 leg(88.5%). Average length was 6.2cm and average diameter was 1.4mm. The main perforator was musculocutaneous perforator at 20 of 26 leg(77%). The posterior tibial artery perforator flap was clinically use in 3 cases. All flap were survived without any complication. Conclusion: The author found the main perforator of posterior tibial artery perforator flap was located 15cm distant from medial boarder of central patella within the circle drawn with a radius of 4cm. The posterior tibial artery perforator flap is expected to be used as one of the option for the reconstruction of hand and foot.

Purpose: Malignant melanoma is a fatal tumor arising in the melanocytic systems of the skin. The incidence of malignant melanoma, formerly considered a rare tumor in Korea, is observed to increase. The aim of this study is to analyze the clinical and histopathological pattern of malignant melanoma in one institute. Methods: Thirty patients with ages ranging from 33 to 80 years, diagnosed as malignant melanoma at our skin tumor department, were enrolled in a retrospective study over a 6 year period(2000. 9-2006. 7). The analyzed data included age, sex, location, duration before diagnosis, clinical type, level of invasion, and stage. Results: The cases were identified and analyzed by clinical and histopathologic study. The male to female ratio was 1:1.7. Lower extremities(especially, feet) were favored sites. The majority of cases were acral lentiginous melanoma(40%), followed by nodular melanoma (36.7%), superficial spreading melanoma(20%) in this study. Clark level IV was predominant in histopathologic study. There was merely narrow gap among each stage by AJCC. Conclusion: The clinicopathological characteristic of melanoma in our patients is quite different with that in the West. In this retrospective study, primary lesions of the foot were predominant with melanoma, and a high percentage of these were classified pathologically as acral lentiginous melanomas. Patients had a more advanced stage of disease at first presentation and a more deeply invasive primary lesion than Western patients. These suggest that malignant melanoma has a worse prognosis in our patients than in the West. So, further organized prospective studies are needed to approach the prudent and accurate diagnosis and management of melanoma in Korea.
