The goal of this paper is to explore and compare the situations of North Korean and Chinese labor forces in the Russian Far East (RFE). First of all, the past and present pictures of North Korean and Chinese labor forces were reviewed, and then local Russinans' views about those foreign workers were analyzed in terms of political, economic, socio-psychological and public order aspects. As a result, it turned out that both North Korean and Chinese workers were regarded as useful to the RFE from economic viewpoint, but not as beneficial to local Russians in terms of maintenance of public order. According to the political and socio-psychological views of local Russians, North Korean labor forces were much more preferable to their Chinese counterparts. This paper implies that participation of South Korea in the development of RFE via North Korea workers is significant in that local Russians are very afraid of flooding Chinese workers there.

In Korea, groundwater management has been conducted based on the estimation of annual average of groundwater recharge. Since groundwater recharge and surface water-groundwater interactions show spatiotemporal variation, continuous monitoring and dynamic analysis must be carried out to evaluate the sustainability of groundwater resources. In this study, SWAT-MODFLOW, an integrated surface water-groundwater model was used to analyze surface-groundwater interactions for various groundwater pumping scenarios in Musimcheon watershed. When current usage is applied, the baseflow reduction is about 16%, and annual averaged storage reduction is about 27 mm for whole watershed. As a holistic approach to groundwater sustainability considers the hydrological, ecological, socioeconomic, technological aspects of groundwater utilization, the exploitable groundwater should be determined by physical analysis as well as social compromise in a community.

The purpose of this paper is to examine the important characteristics of the qualitative research methods and to analyze application of these methods in the field of family therapy. First, general characteristics of qualitative research methods and typical features of qualitative research designs are described. Second, contents related with meanings, adequacy, and application process of qualitative research methods in the field of family therapy are discussed. Third, cardinal issues that could hinder the development of qualitative family therapy research are reviewed. Qualitative research methods provide a scientific and systematic way of looking at family therapy holistically. These methods may add new dimensions to qualitative research in the field of family therapy and thus increase its diversity. The versatility of qualitative research methods is a good match for examining the complexity and the diversity of family forms and experience. Therefore, qualitative research methods has the potential to advance the science and practice of family therapy and that family therapy researchers have the potential to advance qualitative research methods. Implications for the development of qualitative research methods in the field of family therapy in Korea are suggested.

Purpose : Histopathologic observation was performed in order to determine which type of suture material is superior in microvascular anastomoses. Materials & Methods : The interrupted end to end anastomosis of the transected carotid arteries of 105 Sprague-Dawley rats, weighing 180 to 200g, were performed using 9-0 polypropylene ($Prolene^{TM}$, Ethicon, U.K.), 9-0 polyglactin 910 monofilament($Vicryl^{TM}$, Ethicon, U.K.), and 9-0 polyamide($Ethilon^{TM}$, Ethicon, U.K.) under intramuscular Ketamine and Xylazine anesthesia(5mg/100g). In all cases, 10 to 12 sutures were placed to complete the anastomoses. The specimens were obtained at 1, 2, 3 days, and 1, 2, 4 and 6 weeks after the surgery and prepared with H&E and Van-Gieson stains and investigated the histologic changes in anastomotic sites under light microscope. The histologic changes we were concerned about were followings- thrombus formation, intimal edema, infiltration of inflammatory cells in media and adventitia, proliferation of endothelial cells and subintimal hyperplasia. Results : 1. All of the anastomosed arteries were patent when they were exposed for examination. 2. Thrombus formation and intimal edema were most severe in Vicryl group, followed by Ethilon, Prolene group in order. 3. The inflammatory cells infiltrated to the media and the adventitia most severely in Ethilon group, followed by Vicryl, Prolene group in order. 4. There was little difference in proliferation of endothelial cells in each group. 5. Subintimal hyperplasia was greater in Vicryl group than the others, but there was no significant difference between the Prolene and Ethilon groups. Conclusions : On the basis of these observations, we could conclude that Prolene may be the better suture material for microvascular anastomoses regarding the tissue responses than Ethilon and Vicryl.

Von Mises stress and compliance distribution was evaluated using a finite element analysis on the anastomosis of an artery with length of 20mm(z direction, along the horizental artery), inner diameter of 4mm, thickness fo 0.5mm and a PTFE graft with length of 5.7mm, inner diameter of 2mm, thickness of 0.2mm when anastomotic angle was $45^{\circ}$ and inner pressure of 1330 dyne/mm2 was applied inside the 2 conduits. From the analysis results were obtained as follows. (1) Artery diameter increased in both horizontal x(along the length of artery) and vertical y(perpendicular to the length of artery)directions and the magnitude of that in x direction was bigger than that in y direction. (2) The compliance was maximum on the anastomosis, especially on that with acute angle. The reduction of compliance was observed from the anastomosis area to the either right or left end. (3) The equivalent stress was maximum on top in the y direction and minimum on the nodes apart $110^{\circ}$ in circumferential direction from the top. (4) The equivalent stress was maximum in t도 vicinity of anastomosis with acute angle along the longitudinal direction of the artery. This trend was also observed along the PTFE graft.

Von Mises stress and compliance distribution was evaluated using a finite element analysis on the end-to-side anastomosis of an artery with length of 20-24mm, inner diameter of 4mm, thickness of 0.5mm and a PTFE graft with length of 10mm, inner diameter of 2mm, thickness of 0.2mm when the anastomotic angle was taken from 30$^{\circ}$~90$^{\circ}$ in every 10$^{\circ}$ and the diameter ratio from 0.1-1 in every 0.1. The inner pressure of 1330 dyne/$\textrm{mm}^2$ was applied inside the 2 conduits. It was found that the compliance whose magnitude is larger on the acute angle anastomotic side than on the abtuse angle side became larger as the anastomotic angle became smaller and the diameter ratio larger and that the equivalent stress on the acute angle anastomotic side was larger than that on the abtuse angle side and became larger as the anastomotic angle and the diameter ratio became larger.

담배는 오랜 과거부터 규제의 주요 대상이 되어 왔다. 1950년대 이전까지만 해도 담배관련 규제는 담배의 생산 및 제조활동과 함께 윤리 또는 규범적 차원에서 주로 이루어져 왔으나, 1950년대 초 이후부터 흡연의 건강 위해성에 관한 연구가 본격화되고 건강에 대한 공중의 관심이 확산되면서 담배와 흡연에 대한 사회적·법적 규제가 크게 강화되어 왔다고 할 수 있다. 담배산업이 그 동안 지속적인 성장을 하는 가운데에서도 담배와 흡연에 대해 강도 높은 규제가 가해져 온 이유는 담배가 성인들의 기호품으로써 보편화 된데 반해 건강 위해적 요소들을 내재하고 있고, 담배의 높은 수익가치로 인해 담배의 생산 및 판매가 정부의 재정사업으로 관할됨에 따라 정보에 의한 강력한 통제가 불가피했기 때문이라 할 수 있다. 세계 각 국에서 적용되고 있는 담배에 대한 일반적인 규제유형으로는 크게 흡연(smoking) 규제와 판매 및 촉진활동(sales & promotion) 규제, 경고문 부착(labeling)에 관한 규제, 그리고 진입 및 무역(entry & trade) 규제 등으로 구분될 수 있다. 한국의 경우는 전통적으로 흡연에 대해 매우 관대한 태도가 유지되어 왔으나, 95년도 중반 이후 국민건강 증진법 등의 규제법률이 제정·시행되면서 제도적·정책적 규제가 크게 강화되어 현재는 세계 최상위 수준을 유지하고 있다고 할 수 있다. 이러한 가운데 99년 5월 이후, 담배에 대한 표준화된 규제지침의 설정과 강화를 통해 궁극적으로 세상에서 담배를 근절시키고자 하는 목적 하에서 세계보건기구(WHO)의 주 역점사업으로서 추진되고 있는 담배규제협약(FCTC)은 담배에 대한 규제가 초국가적 차원으로 발전되는 계기를 제공하고 있다. 향후, 담배규제협약안의 세부사안들에 대한 합의과정에서 각 국별로 상당한 이견과 반발이 예상되고 있지만, 협약안의 전체 회원국 투표에서 승인될 경우 각 국가들뿐만 아니라 담배산업과 담배기업들에게 미치는 파급효과가 매우 클 것으로 예상된다. 대부분의 국제협약들이 그러하듯이, 담배규제협약도 그 적용 범위와 수준이 어느 정도로 결정되는지에 따라 각 국가와 기업별 이해관계가 크게 달라지게 되기 때문에 신중한 대응전략이 요구된다고 하겠다.

Common carotid artery occlusion (CCAO) is a very rare disorder that has rarely been studied. CCAO causes several neurological symptoms but can sometimes be asymptomatic due to the development of various anastomoses. Herein, we report the case of a 70-year-old male patient diagnosed with asymptomatic CCAO due to anastomotic flow. The patient underwent transfemoral cerebral angiography (TFCA) and was found to have CCAO with two collateral pathways, including an occipital artery-vertebral artery anastomosis. We emphasize the importance of TFCA when CCAO is suspected and review the types and anastomotic pathways of CCAO.

A mixed-breed hunting dog suffered penile amputation and lacerations in the femoral and inguinal areas while hunting wild boar. The penis was replanted by anastomoses of the urethra, cavernous body, and the left and right dorsal veins of the penis. The transected penis recovered anatomically and functionally. No evidence of postoperative necrosis or edema was detected at the distal portion of the penis. In addition, fistulas and stenosis were not found on urethrogram 20 days after the surgery. Aside from surgery, we performed experimental cavernosography to identify the importance of the anastomosis of the dorsal veins of the penis in three beagle dogs. The cavernosograms revealed that, the contrast medium, which was injected into the bulbus glandis, drained by the left and right dorsal veins of the penis, then converged into one vessel at the ischial arch and diverged into the left and right internal pudendal veins. Thus, reanastomosis of the left and right dorsal veins of the penis in cases of transected canine penis appears to be important for positive postoperative prognosis.
