  • The purpose of this study is to investigate the changes of ginseng properties through bibliographical records. The cultivation of Korean wild simulated ginseng (mountain cultivated ginseng) started from the Goryeo Dynasty around A.D. 1000. Thereafter, from A.D. 1500 to A.D. 1600, ginseng cultivation technology was established in the Joseon Dynasty. At this time, the ginseng was begun to grow in the field near the house, and it is recorded as Gasam (field cultivated ginseng). The Jung-Jo-Sil-Rok (A.D. 1790) states that Gasam cultivation has expanded to the whole country. The properties of ginseng described in almost all oriental medicine books from A.D. 250 to A.D. 1600 were a slightly cold. However, after A.D. 1600, it is said to be slightly warm or warm. Considering from this record, the slightly cold ginseng before A.D. 1600 can be recognized as the properties of wild ginseng or wild simulated ginseng, and the slightly warm ginseng after A.D. 1600 can be recognized as Gasam properties.

  • The Benangkimi wetland, which serves as a stopover place for migratory birds in the Dadohae Marine National Park in Wando-gun, Jeollanam-do, is a place where various species and a large number of migratory birds are observed. In order to provide an effective and scientific management plan for the habitat environment of migratory birds, we carried out field survey of Benangkimi wetland. The field survey and survey on habitat use of migratory birds were conducted in parallel to obtain the basic data of hydraulics and hydrology. The hydraulic and hydrological survey of Benangkimi wetland was conducted 1-2 times a year during the period of 2015-2016 (two years). It was classified into 4 sectors according to the topography and geology, rainfall, hydraulic characteristics, and wetland conditions. The 3 sectors same as the migratory birds survey sector and the 1 sector as the inflow of the wetland were analyzed. The survey also focused on small migratory birds arriving at Benangkimi wetland during the spring and autumn season. As a result of investigating the population and species in each section, the habitat environment was different according to the water depth, sediment thickness and salinity. Migratory birds prefer hydraulic and hydrological characteristics. This study will be used for the scientific management of Benangkimi wetland, which serves as a stopping point for migratory birds, and it will contribute to basic data of ecology - hydraulics by examining the relationship between habitat environment and hydrological data.

  • Accurate assessment of the effect of jet plume on the boattail pressure drag of transonic airbreathing missiles is very important to reduce drag and to satisfy the flight range and the required maneuver. Numerical results of drag analysis for boattail and base pressures due to jet plume are presented considering the turbulence modeling. Drag assessment due to the size of jet plume, the conditions of the exhaust gas, the configurations of the boattail, and transonic mach numbers is included.

  • Loss of mandibular continuity due to neoplasm, trauma, or infection results in major esthetic and biologic compromise. The use of costochondral grafts for reconstruction of temporomandibular joint, described first by Gillies in 1920, has been accepted as a suitable method for replacing the mandibular condyle, especially in growing children. Autogenous iliac bone graft has been a satisfactory source of mandibular reconstruction since Sykoffs report in 1900. Autogenous bone grafts from the posterior aspects of the ilium provide large amount of PMCB with acceptable donor site morbidity. In timing of reconstruction, initial disease, age, medical history, growth and development, esthetic and psychologic factors should be considered. We present a case of osteosarcoma in the mandible that was treated by a hemimandibulectomy and the defect was reconstructed 20 months later with composite method of costochondral and posterior iliac bone graft.

  • 통계청의 8월 고용동향과 경제활동 인구조사에 따르면, 지난달 국내 실업률은 3.5%로 실업 인구 수가 80만명에 이른 것으로 나타났다. 이중 20대 청년실업자가 차지하는 비율이 40.7%로 전체 실업자의 절반에 육박하고 있어 현재 청년실업 문제가 매우 심각한 것으로 조사됐다. 특히 최근 들어 벤처기업의 1사 1인 채용운동 등 각계에서 고용안정을 위한 다양한 노력을 기울이고 있음에도 불구하고 실업난이 수그러들 기미를 보이지 않음에 따라 취업 알선을 위한 보다 정확하고 신속한 정보 제공이 요구되고 있다. 더구나 중앙고용정보원의 워크넷이나 중소기업청의 인력정보망 등 온라인을 통한 다양한 구인∙구직 사이트들이 활성화돼 있어 구직 희망자들이 적극 활용하고 있는데, 내수침체가 장기화되면서 고용 사정은 좀처럼 개선되지 않고 있다. 2004년 현재 온라인상으로만 채용공고를 하는 기업은 전체 기업의 30% 정도이며, 앞으로는 온라인을 통한 구인구직 활동이 더욱 활발해질 것으로 전망되고 있다. 실제 인터넷에서 채용정보 전문 서비스는 물론 분야별, 지역별로 구인구직 정보를 제공하고 있는 서비스를 합하면 350여개가 넘는다. 이 중 눈에 띄는 서비스가 바로‘워크넷’이다. ‘워크넷’은 노동부 산하 중앙고용정보원이 운영하는 구인구직 전문 사이트로서, 공공기관이 운영한다는 점에서 정보의 신뢰성과 전문성이 기대된다. 특히 하반기 채용 시즌을 맞아 구인구직활동이 더욱 활발해 질것으로 예상되기 때문에 이번 10월 DB서비스 평가에서는‘워크넷’을 소개하고자 한다.

  • Taking the perspective of children's welfare, this study aimed at critically analyzing the system of notification disposition which institutionalized children have experienced. Notification disposition is a juvenile justice process that, when a child (10 th 18 years old ) has been delinquent or is at risk for delinquency, is initiated without investigation or prosecution procedures by direct notification to a judge from the caregivers, school principals, chief probation officers, or directors of child care institutions. The data used in the analysis included case records of probation offices, and court sentencing documents of juvenile protective dispositions. Results showed that notification cases were initiated by directors of child shelters/care institutions. The most common reasons of notification were theft, runaway, physical violence, drinking, and smoking. Furthermore, there were more controversial reasons, such as "bad influence on another institutionalized children", "showing no remorse", "no sense of guilt"and "challenge of rearing in institutions" Based on the results, we discussed three problematic aspects of the direct notification system by directors of childcare institutions : (1) too much reliance on the judicature judgment of juvenile court; (2) less stability of the judicial status of notified children, and (3) inadequacies of the notifying eligibility for directors of child care institutions.

  • Chinese people have increasingly high interests in skin care and trust and prefer medical institution products and equipment to treat skin problems. The purpose of this study is to examine skin types and skin care situations, skin care recognition, and skin care satisfaction by gender in medical skin care center patients from in their 10s to 50s in Hainan Province, China. The questionnaire survey consisted of general characteristics(n=8), skin care situations(n=6), skin care recognition(n=11), and skin care satisfaction(n=21). A total of 328 questionnaires were researched from December 21, 2020 to January 9, 2021 using WeChat and Wenjuanxing program. Data were analyzed by SPSSWIN 21.0. Frequency analysis was applied for general characteristics, skin care situations, skin care recognition, and skin care satisfaction and Cronbach's α was used for the reliability of skin care recognition and satisfaction. The relationship among skin care situations, skin care recognition, and skin care satisfaction was analyzed by χ2 test and t-test. As a result, the common skin types by gender was dry skin in females and oily skin in males. The highest skin trouble was melasma and pigments in females and pimple in males. The most common way to manage troubled skin was homecare in both females and males, followed by the dermatology department in females and pharmacy in males, suggesting a significant difference. The common period of skin trouble was from one year to three years and the most effective way to improve skin was good life habit, followed by laser treatment in both females and males. The most important consideration to choose a hospital was a famous franchise hospital and the most important matters in management was doctor or skin care professionalism. Skin care and treatment recognition was high in external effects for females and internal effects for males. Skin care satisfaction was high in service for females and effect for males. Skin care satisfaction was significantly higher in males than in females. In conclusion, there was a difference in skin types, skin troubles, skin problems, skin care ways, and skin care satisfaction by gender in Chinese medical skin care center patients. Therefore, this study suggests the development of various products and the need of systematic management programs.
