기존 한옥의 계승을 위한 관련 연구가 진행되고 있으나, 한옥 보급에는 실용성을 띄지 못하고 있다. 이는 한옥 시공기술의 복잡성과 자재 생산기술 부족으로 인한 제한적 범위 내에서 공사가 진행됨에 따라 높은 공사비를 원인으로 꼽을 수 있다. 이에 따라 현재 전통 한옥이 가진 정체성을 살리고 현시대에 보급될 수 있는 신 한옥으로의 진화를 위해 부재간의 연관을 분석하고 조립하는 방식을 지식으로 구성하고 디지털 모델링을 함으로써 공사비 절감이 가능케 하는 방법 등이 연구되고 있다. 본 연구에서는 한옥 설계자를 고려한 효율적인 부재 가공 정보 지원을 목표로 한옥 부재 실무 가공 분석을 통해 경제성, 시공성을 파악하고 최적화 방안을 위한 한옥 부재 제작 CNC 시뮬레이션을 통해 효율적인 가공 프로세스의 발전 가능성을 예측하여 최적화된 부재가공 정보를 제안하고 이를 기반으로 한옥 수요자들을 위한 설계지원 방법에 대한 구체적인 방안을 제시함으로써 한옥의 생상성 향상에 기여하고자 한다. There have been a lot of studies about the Han-ok, the Korean-style house, in perspective of the inheritage of existing ones, but there are no practicality in the supply of Han-ok. The cause is considered to exist in the complexity of Han-ok and the techniques required to manufacture its components and in the relatively higher construction expenses in the process which is within restricted range. On the contrary, in order to preserve the identity of traditional Han-ok and encourage the evolution to create a new Han-ok that can be supplied to the present period, there has been studies that analyzes the connection between sub-components and assemble them into a digital model which can possibly decrease the expenses spent on construction. The research`s objective is to provide valuable information for Han-ok designers, which contains methods on manufacturing sub-components effectively. Furthermore, by analyzing the current manufacturing method`s workability and economic feasibility, the research can obtain an optimum alternative for improving Han-ok`s production. Also by using CNC simulation, the possibility of an effective production can be predicted, as well as the information that can lead to the optimum method for an efficient sub-component manufacturing and suggest a specific resolution which can also affect on the improvement of Han-ok productivity.

There have been a lot of studies about Han-Ok, the Korean-style house, in the perspective of existing Han-Ok’s inheritance, but there are no practicality in supply of Han-Ok. The cause is considered the complexity of Han-Ok construction techniques and higher construction expenses comparatively by processing in the restricted range by the shortage of the manufacturing technology of materials. On the contrary, for evolution to the new Han-Ok that can be supplied to the present period, there are studies that is analyzed the connection between sub materials and for possible modeling by formulating of assembling way. Thus, this study try to suggest the CNC process for new Han-Ok construction to secure construction relate to construction technique, which is determined by few expert technicians that is pointed out as problems of Han-Ok.

감 품종별(도근조생, 고종시, 갑주백목, 차랑, 월하시, 상주둥시)로 감꽃을 개화기에 채취하여 동결건조 분말화한 감꽃분말에 함유된 유효성분을 분석, 비교하였다. 조지방 함량은 도근조생이 57.26%로 가장 높은 값을 보였으며, 유리당 조성은 fructose가 95~310 mg%, glucose는 75~281 mg%, sucrose가 7~28 mg%의 함유량을 나타내었고, 유기산 중 malic acid가 갑주백목(6월4일)에 225 mg%로 가장 많았고, tartaric acid도 189 mg%로 가장 많았다. 유리아미노산 중 hydroxy-L-proline은 월하시에 25.33 mg%, L-citrulline은 상주둥시(5월28일)가 58.83 mg%, L-threonine은 상주둥시(5월28일)가 11.88 mg%로 가장 많았다. 페놀산으로 caffeic acid는 갑주백목(6윌4일)이 1946 μg/100 g, phydroxybenzoic acid는 상주둥시(5월29일)가 417.8 μg/100 g, protocatechuic acid는 갑주백목(6월1일)이 181.1 μg/l00 g으로 가장 많았다. 따라서 감꽃에도 감이나 감잎에 못지않게 유용한 식품성분들과 기능성 성분들이 다량 함유되어 있어 새로운 식품 및 기능성 신소재로서의 가치가 매우 높다고 할 수 있다. This study was carried out to analyze useful components in freeze-dried persimmon flower powder made from six cultivars. The cultivars were Dogunjosang, Kojongsi, Kabjubaekmok, Chalang, Weolhasi and SangjuDungsi. Powder of persimmon flower was prepared by milling after freeze drying at -70℃. Crude lipid was the highest in Dogunjosang (57.26%). Major free sugars of the persimmon flowers were fructose (95~310 mg%), glucose (75~281 mg%)and sucrose (7~28 mg%). Major organic acids were malic acid (225 mg% in Kabjubaekmok (Jun. 4th)) and tartaric acid (189 mg% in Kabjubaekmok (Jun. 4th)). Predominant free amino acids were hydroxy-L-proline(25.33 mg% in Weolhasi), L-citrulline (58.83 mg% in SangjuDungsi (May 28th)) and L-threonine (11.88 mg% in SangjuDungsi (May 28th)). Major phenolic compounds in the persimmon flowers were caffeic acid (1,946 μg/100g in Kabjubaekmok (Jun. 4th)), p-hydroxybenzoic acid(418 μg/100g in SangjuDungsi (May 29th)) and protocatechuic acid(181 μg/100g in Kabjubaekmok(Jun. 1st)). The results suggest that persimmon flowers be potential materials as useful food ingredients.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

이준한 ( Jun Han Lee ),김경호 ( Kyoung Ho Kim ) 충북대학교 건설기술연구소 2015 建設技術論文集 Vol.34 No.1

파일 주변에 발생하는 세굴을 감소시키는 방법은 크게 1)세굴에 대한 해저 지반의 저항력을 증가시키는 방법과, 2) 세굴을 일으키는 요인(하강류, 말굽형 와류, 배후류 등)의 흐름을 차단함으로서 세굴 유발능을 감소시키는 두 가지 방법으로 대별된다. 본 논문에서는 파일에 원형 반사판을 설치하여 접근 흐름의 하강 유속을 감소시켜 세굴을 억제하는, 후자의 방법에 대하여 실험적 연구를 수행하였다. 사용된 파는 주기와 파고를 각각 달리하는 정현파를 이용하였고, 세굴 방지공은 방지공의 간격파 부착되는 방지공익 개수를 변화시키며 감소 효율을 측정하였다. 측정된 감소공의 각각의 효율파 KC 수와의 상관성을 검토하여 최적화된 방지공의 구성을 분석하였다. 실험결과, 평균 감소율은 36.8%였으며, 가장 효과적인 세굴방지공은 두께와 간격비가 0.25일 때,평균 감소율이 52.3%였다. There are two methods to protect the damage of the scour around a pile. One is the method of increasing resistance of seabed, and another is that of controlling flow causing scour such as down flow, horseshoe vortex and lee-wake vortex. The former is to place protecting layer using riprap or tetrapod around a pile. The latter is to install protection devise. Experiment of the reduction of scour around a pile using protection wing are carried out under regular wave. Experiments are performed with the variation of the breadth and interval of the protection wing, wave periods(T) and wave heights (H). The each experiment shows that protection reduces the scour depth. Using the experimental results, combination of breadths and intervals the protection wing is found. Finally, the correlations of relative scour depth and KC number were analyzed. The average reduction of the scour depth by the protection wing is 36.8%. The breadth - interval ratio of protection wing was found to be 0.25 for the best combination, in which average scour depth reduction was 52.3%.

Pretreatment with Lycopene Attenuates Oxidative Stress-Induced Apoptosis in Human Mesenchymal Stem Cells

Kim, Ji Yong,Lee, Jai-Sung,Han, Yong-Seok,Lee, Jun Hee,Bae, Inhyu,Yoon, Yeo Min,Kwon, Sang Mo,Lee, Sang Hun The Korean Society of Applied Pharmacology 2015 Biomolecules & Therapeutics(구 응용약물학회지) Vol.23 No.6

Human mesenchymal stem cells (MSCs) have been used in cell-based therapy to promote revascularization after peripheral or myocardial ischemia. High levels of reactive oxygen species (ROS) are involved in the senescence and apoptosis of MSCs, causing defective neovascularization. Here, we examined the effect of the natural antioxidant lycopene on oxidative stress-induced apoptosis in MSCs. Although $H_2O_2$ ($200{\mu}M$) increased intracellular ROS levels in human MSCs, lycopene ($10{\mu}M$) pretreatment suppressed $H_2O_2$-induced ROS generation and increased survival. $H_2O_2$-induced ROS increased the levels of phosphorylated p38 mitogen activated protein kinase (MAPK), Jun-N-terminal kinase (JNK), ataxia telangiectasia mutated (ATM), and p53, which were inhibited by lycopene pretreatment. Furthermore, lycopene pretreatment decreased the expression of cleaved poly (ADP ribose) polymerase-1 (PARP-1) and caspase-3 and increased the expression of B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax), which were induced by $H_2O_2$ treatment. Moreover, lycopene significantly increased manganese superoxide dismutase (MnSOD) expression and decreased cellular ROS levels via the PI3K-Akt pathway. Our findings show that lycopene pretreatment prevents ischemic injury by suppressing apoptosis-associated signal pathway and enhancing anti-oxidant protein, suggesting that lycopene could be developed as a beneficial broad-spectrum agent for the successful MSC transplantation in ischemic diseases.
