Background Scalp defects may be caused by various etiological factors, and they represent a significant surgical and aesthetic concern. Various surgical techniques can be applied for reconstructive work such as primary closure, skin grafting, pedicled or free flaps. In this article, the authors share their clinical experience with scalp operations using the technique of local flaps and discuss the application of this method from the perspective of not only the size of the defect, but also in relation to the anatomical area, quality of surrounding tissue, and patient's condition. Methods During the period from December 2007 to December 2012, 13 patients with various scalp defects, aged 11 to 86 years, underwent reconstruction with local pedicle flaps. The indications were based on the patients' condition (age, sex, quality of surrounding tissue, and comorbidities) and wound parameters. Depending on the size of the defects, they were classified into three groups as follows: large, 20 to 50 $cm^2$; very large, 50 to 100 $cm^2$; extremely large, 100 $cm^2$. The location was defined as peripheral (frontal, temporal, occipital), central, or combined (more than one area). We performed reconstruction with 11 single transposition flaps and 1 bipedicle with a skin graft on the donor area, and 2 advancement flaps in 1 patient. Results In all of the patients, complete tissue coverage was achieved. The recovery was relatively quick, without hematoma, seroma, or infections. The flaps survived entirely. Conclusions Local flaps are widely used in scalp reconstruction since they provide healthy, stable, hair-bearing tissue and require a short healing time for the patients.

수용해도가 2.53ppm인 KC-6620을 수중용출기간이 20일 정도인 입제로 제제하기 위하여 원제에 대한 용출지연효과가 가장 큰 다공성 증량제를 선발하고, PEG를 부제로 첨가한 흡착식 입제를 제제하여 실내에서 수중용출속도를 측정하였다. 1. 다공성 증량제중 KC-6620에 대하여 용출지연효과를 나타낸 것은 bentonite 소결공립이었으나 수중에 침적 20일후의 용출율이 매우 낮았다. 2. Bentonite에 pyrophyllite를 혼합하고 조립한 다음 소결시킴으로써 흡유가가 증가하였으며, 이 공립으로 제제한 KC-6620 입제의 수중용출속도도 증가하였다 BP60 입제의 경우 침적 20일후에 85% 이상의 용출율을 보여 시험한 입제중 단기용출지연제제로 가장 적합하였다. 3. BP입제는 PEG를 부제로 첨가하여 용출속도를 증가시킬 수 있었으며, PEG의 첨가비가 공립의 흡유가까지 증가할수록 용출속도도 증가하였다. 4. BP40 입제는 입제중의 유효성분함량이 높을수록 수중용출속도가 느려져서 제제농도가 용출속도를 좌우하는 가장 큰 요인이었다.

This study was a descriptive cross-sectional study using questionnaire that analyzed the relationship between stress coping types and life goals in the freshmen. The study period lasted from May 1, 2020 to May 20, 2020. A total of 282 people participated in the study, with freshmen enrolled in C and J provinces. The collected data were analyzed frequency, t-test, multiple regression, and Pearson correlation using SPSS 18.0. As a result, the passive(r=.202, p<0.05), aggressive(r=.243, p<0.05), Supportive(r=.255, p<0.01) and active stress coping types(r=.410, p<0.01) were correlated with achieve oriented life goal. And Supportive(r=.383, p<0.01), Active stress coping types(r=.497, p<0.01) were correlated with life oriented goal. According to gender, men (Mean 1.87, SD=0.62) had higher aggressive stress coping types than women (Mean=1.54, SD=0.52) (t=4.202, p=.000). People with achieve oriented life goals were found to have an effect on passive (t=7.176, p<0.01), aggressive (t=1.974, p<0.05) and evasive stress coping types (t=4.207, p<0.01). People with life oriented life goals were found to have ab effect on passive (t=6.331, p<0.01)), active stress coping types (t=2.101, p<0.05). In addition, passive (t=2.946, p<0.01), aggressive (t=4.067, p<0.01) and evasive stress coping types (t=2.624, p<0.01) affected achieve oriented goals, supportive stress coping types (t=5.438, p<0.01) affected the life oriented life goal, and active stress coping type affected on both achieve (t=4.061, p<0.01) and life oriented life goal (t=6.905, p<0.01).

처분시설은 폐쇄 후 제도적 관리기간 동안에는 처분 부지로의 일반인의 접근을 제한하며 제도적 관리기간 이후에는 부주의 한 인간침입 시에도 처분시설로 인한 방사선적 영향으로부터 침입자를 보호하도록 설계 되어야 한다. 본 논문에서는 처분시설이 부주의한 침입자에 미칠 수 있는 방사선적 영향을 GENII 프로그램을 사용하여 평가해보았다. 처분고별 적치되는 방사성폐기물의 종류를 달리하여 평가하고 제도적 관리기간 설정에 따른 침입자에 대한 영향도 분석하였다. 평가결과 제도적 관리기간을 두지 않아도 폐필터가 적치된 처분고를 제외하고 모두 성능 목표치를 만족하였다. 하지만 폐필터를 적치한 처분고의 경우 인간침입 평가결과 제도적 관리기간 300년이 되어서야 성능목표치를 만족할 수 있었다. 폐필터와 함께 잡고체 폐기물을 혼합하여 적치하는 경우 제도적 관리기간을 줄일 수 있었으며, 폐필터는 다른 폐기물과 함께 적치하여 제도적 관리기간을 줄이는 것이 필요하다. 폐기물 적치시 방사능을 고려하여 처분고 적치방안을 적절히 수립하는 것이 국부적인 방사능의 최대값을 줄일 수 있어 방사선적 안전성을 확보하며 제도적 관리기간을 단축할 수 있어 바람직하다.

Purpose : Myofascial decompression is frequently mentioned as a method applied to cupping. The purpose of this study is to evaluate and compare active range of motion (AROM), muscle strength, and functional movement by applying myofascial decompression to the hamstrings. Methods : This study evaluated AROM, muscle strength, and functional movement by applying active movement myofascial decompression and static myofascial decompression to the dominant leg, respectively, in a crossover design conducted with normal adults (n=21) in their average 20s enrolled at G University in G city, Gyeongsangbuk-do. Active movement myofascial decompression was implemented for five minutes at a rate of 100 bpm to make the beats in flexion and extension respectively. Static myofascial decompression was only performed for five minutes while at rest. All of these interventions were performed at a cupping depth of two mm. After a one-week washout period, static was applied again to compare the same dependent variables. Results : Regarding AROM and muscle strength, both groups showed significant differences in the before and after results (p<.05). However, in the Functional Reach Aspect and Single Leg Hop test, the active movement myofascial decompression group showed better results. There was no statistical difference between the Active movement myofascial decompression group and Static myofascial decompression group in any dependent variable (p<.05). Conclusion : As a result of this experiment, both active movement myofascial decompression and static myofascial decompression had a positive effect on dependent variable. Therefore this study is meaningful in that it is easier and simpler to see the effect on flexibility, muscle strength, and functional movement just by implementing movement myofascial decompression.

Only one hundred years of history in nursing education in Korea is not enough to develop the subject fully as a science. However, the development of Korean nursing education is a great historical event, because Korean nursing education has been accepted by a male-oriented Korean society and has led to a new paradigm in the new millenium. These results are largely due to the Korean people's high enthusiasm for education, as well as Korean women's diligence. I think these 100 years of history can be divided into five periods: (1) the Sunlight period (1900-1911) (2) the New born period (1912-1945) (3) the Settle-down period (1946-1960) (4) the Marked Growth period (1961-1980) (5) the Jumping Period (1981-2000) These classifications are characterized by changes in the educational system, a changed nursing curriculum, educational goals, educational outcomes, and implications. The characteristics of historical development of Korean nursing education was evaluated in three dimensions: structures, contents, and outcome. The structure of Korean nursing education consists of a 3-year program and a 4-year program. Most nursing leaders in Korea hope that these two programs will converge into one system. Secondly, the contents of nursing education in Korea underwent very active changes, according to historical development. These changes in the nursing curriculum have been developed to provide a professional education and develop nursing education as a modern science. Lastly, as to the results of nursing education in Korea, the education was needed to turn out advanced specialists in nursing. In the new millenium, knowledge and information will be the driving forces behind social development. A nation's level of development and creativity in nursing education is the most potent determinant of the future of Korean nursing. The best way to prepare for future challenges will be to create the backbone of a nursing education system. Hence, well-educated nurses in graduate programs should be turned into advanced specialists in nursing. These groups will upgrade the image of Korean nurses, and will have strong influence to improve patient care and the health situation in Korea.

It is very critical to specify certain medical personnels in defining the history of certain era. Due to the limited source of information and lack of thorough research, there still aren't enough study grounded on concrete historical investigation. Authors attempted to investigate those medicinal personnels engaged in Three Kingdoms period in terms of the activity area, relation with religion and their role in medical system and medical exchange. The sum of recorded medical personnels in Three Kingdoms period numbers 50 of which 6 belonged to Kokooryo, 18 to Baekje, 7 to Shilla and 19 to Unified Shilla. There might existed far more medical personnels who tried to alleviate the suffering of the people and were not recorded in the documents. The more earlier in times, the more medicine gets the religious tinge. This is not the exception for the period of the Three Kingdoms and those medicine men, wizard doctors and priest doctors were playing important role in healing people and processing crude drugs. The system of royal physician and medical education facility were established and doctors and pharmacists, shamanic doctor, herb collectors, Kongbong's doctor(供奉醫師), Kongbong's diviners(供奉卜師) took leads in medicine in those times. Those folkloric healers also took part in. Korea imported chinese medicine and Japan employed chinese medicine via Korea or directly from China and developed into traditional japanese medicine. In this process those who emigrated from Baekje and Kogooryo and their offsprings took an active part. Since the limited source of information of Three Kingdoms, we only can infer the me야cal environment of those times by featuring the activities of medical personnels.

Through this paper, all the provisions of the enforcement statutes stipulated in the Joseon's law code were investigated and major medical issues and interests in the Joseon Dynasty were analyzed. The characteristics of each period reviewed in the text are as follows. The early Joseon Dynasty is divided into three periods. First of all, Joseon filled the gap in the law with the active acceptance of the Ming Dynasty's law code, Daemyeongrul, which conformed to Confucian virtue. Next, the completion of Gyeonggukdaejeon was an opportunity to prepare the basis for Joseon's medical laws. Lastly, from the late 15th century to the 16th century, the existing medicine promotion measures and emphasis on hyangyak(domestic herb) continued. it can be said that Joseon's politicians needed a medical policy based on Confucian virtues and maintained state-led promotion policies, but on the other hand, there was no other alternative to try newly by reflecting the limitations and failures of the policy. The late Joseon Dynasty is also divided into three periods. First of all, the period from the late 16th century to the early 18th century was marked by the growth of families in technical positions. The era of King Yeongjo can be said to be the period of reorganization of medical related laws. Finally, the period after the late 18th century is a period of passive regulation and supplementation. Lastly, the revision of the actual medical law was not made or reflected in era of King Jeongjo. In the case of the early Joseon Dynasty, the policy shifted from state-led to families in technical positions. However, in the 19th century, the weakening of the royal authority led to the weakening of the overall administrative system of the country, and the pharmaceutical policy had to be limited.
