Objective This study aimed to introduce a method to remove huge ovarian tumors (≥15 cm) intact with single-port laparoscopic surgery (SPLS) using SW Kim`s technique and to compare the surgical outcomes with those of laparotomy. Methods Medical records were retrospectively reviewed for patients who underwent either SPLS (n=21) with SW Kim`s technique using a specially designed 30×30-cm2-sized 3XL LapBag or laparotomy (n=22) for a huge ovarian tumor from December 2008 to May 2016. Perioperative surgical outcomes were compared. Results In 19/21 (90.5%) patients, SPLS was successfully performed without any tumor spillage or conversion to multi-port laparoscopy or laparotomy. There was no significant difference in patient characteristics, including tumor diameter and total operation time, between both groups. The postoperative hospital stay was significantly shorter for the SPLS group than for the laparotomy group (median, 2 [1 to 5] vs. 4 [3 to 17] days; P<0.001). The number of postoperative general diet build-up days was also significantly shorter for the SPLS group (median, 1 [1 to 4] vs. 3 [2 to 16] days; P<0.001). Immediate post-operative pain score was lower in the SPLS group (median, 2.0 [0 to 8] vs. 4.0 [0 to 8]; P=0.045). Patient-controlled anesthesia was used less in the SPLS group (61.9% vs. 100%). Conclusion SPLS was successful in removing most large ovarian tumors without rupture and showed quicker recovery and less immediate post-operative pain in comparison to laparotomy. SPLS using SW Kim`s technique could be a feasible solution to removing huge ovarian tumors.

The Three States era of Gogooryeo, Baekjae and Shilla had the most colorful and versatile metal crafts. Especially jades were widely used along with various metals in ornaments. Necklaces werea typical symbol of royal class and although there were similarities, each country had their own characteristics. In this study, in-depth analysis on necklaces, which played more important roles during the Three States era is reported as well as kinds, materials, and shapes of necklaces, and the results are as follows. The kinds of ornaments utilizing jewels during the period of the Three States are crowns, Gwan-Sik, earings, necklaces, bracelets, rings, belts, buckles, shoes, and hair accessories. The shapes of jewels used for ornaments during the Three States era are Kok-Ok(curved Jades), Kwan-Ok(piped Jades), Ko-Ok(drum-shaped), Cho-Ok, DaMeun-Ok (multifaceted), SanChi-Ok, Ho-Ok, MilGam-Ok, IHyung-Ok. The shapes of IHyung-Ok are MoJaGok-Ok. NanHuyng-Ok Ga Ja Huyng-Ok (egg-plant shaped). PyoHyung-Ok(gourd dipper-sha ped). Materials used are jades, agate, maroon colored agate, amber, amazon stone, quartz, emerald, aventurine, topaz, microcline, serpentine, willemite. The ornaments of the Three States era show characteristics shapes and unique kinds of jewels. Characteristics of Gogooryeo show natural and smooth yet powerful craftsmanship us ing Tu-Gak, plating, and metal carving techniques. As for jewelry ornaments, it is difficult to say of the shapes since there has been no known artifacts unearthed. But a complete version of a necklace from Gogooryeo has never been discovered, so it is difficult to know the exact form. Necklaces from Baekjae show prominent Baekjae craftsmanship styles with various shapes and kinds of jades compared to Shilla and Gaya. They show advanced glass coloring technique. Their advanced MoJaGok-Ok show subtle Baekjae craftsmanship, which only flourished in Baekjae. Shilla had the most brilliant and various golden ornaments of all. Specifically, Shilla had highly precise and accurate skills in gold ornamenting. Shilla widely used curved jades and their carving skills on jade were unique. As for materials, they used gold laiden curved jades unlike other states. Gaya was not much different from Shilla except that they used simple earthen jades. As seen in styles and usages of necklaces of the Three States era, manufacturing and usage was determined according to the polishing styles and necklaces. The relationship amongst ornaments according to their styles and materials are as follows. Gu-Ok(Ball-shaped jades), So-Ok(small jades), DaMeun Ok (multifaceted jades), Kwan-Ok(pipe-shaped jades), gemma were mainly used for necklaces. Based on styles and materials used during the Three States era necklaces were produced using agate, red agate, topaz, jades, purple agate, and amethyst. As you can see the necklaces of each countries of the Three States Era has its own characteristics, as in the figure of the jade or its usage. The necklaces of the Three States Era can be categorized by its material or form. In materials there are pure gold, pure gold mixed with glass, and various jades. In form there are one string necklaces, and two string necklaces. As you can see the necklaces of the Three State Era have its own characteristics by the country, and there were also various shapes of the jade and usage.

In this thesis, I investigated the inclination to novel in the biographies of Lee Ok. This dissertation is a study to understand the novels of Lee Ok and a representative man of the Chosun Dynasty. Lee Ok, born in the disorderly late Chosun Dynasty, was alive an obscure life because he was ruined the upper class (Yang-Ban) during Chosun Dynasty. So his literary works represented about neglected common people class. His life had influence on literary works. Lee Ok wrote twenty three novels. Each of the twenty three novels didn't deal with in this study. This study discloses the variety of fictional techniques of Lee Ok. So this study fully examined one of the Lee Ok's novel (Sim-Seong-Jeon). His novel world, idea, and viewpoint of literature, based on his obscure life, are the recognition and limitation against social injustice. It is formed to his right recognition of history, and to the criticism of society in consistency to sympathy for pityful people. His literary works have the resistances against the social inconsistency.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Atherosclerosis is now viewed as an inflammatory disease of the vascular system. Expression of several chemokines, including monocyte chemoattractant protein(MCP)-1, MCP-4, RANTES(regulated on activation normal T-cell expressed and secreted), and interleukin-8(IL-8) are increased in human atherosclerotic plaques compared with normal vessels. They are involved in the pathogenesis of atherosclerosis and plaque rupture by activating and directing leukocytes into the atherosclerotic lesions. However, some are involved in homeostatic functions such as normal leukocyte traffic and growth regulation. SDF-la is a multi-functional cytokine that is involved in myelogenesis, hematopoiesis, angiogenesis and injured gastric mucosal regeneration in the gastric ulcer patient. SDF-la is recently shown to be highly expressed in atherosclerotic plaques and a potent platelet agonist. At least in high concentrations, SDF-la may mediate antiinflammatory and matrix stabilizing effects in unstable angina. Many studies are going on to know the function of SDF-la in coronary artery diseases. I investigated the difference of the plasma level of SDF-la between control group and coronary artery disease group. Total 75 subjects were enrolled. The diagnosis of coronary artery disease was confirmed in all patients by coronary angiography. Control subjects in this study were confirmed normal by coronary angiography. Clinical profile and risk factors were also reviewed. Control subjects in this study were 27 (M=10, F=17). Plasma for the study was collected before the angiography and centrifuged. SDF-la analysis was performed by ELISA. Plasma level of SDF-la is significantly increased in patients with stable angina(n=20) and unstable angina group(n=28) compared with healthy control group(n=27). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases. In this study, plasma level of SDF-la is increased in patients with stable angina and unstable angina groups compared with healthy control group(P<0.05). the risk factors do not influence the plasma level of SDF-la in coronary artery diseases.

To compensate phase shift caused by the electronics, the distance meter employs two optical paths, generated by splitting the laser beam into an internal fixed path and a variable distance external path. Because of the perturbations of the atmospheric index of refraction, the amplitude of the external path signal may vary greatly It is necessary to equalize the internal path amplitude with the external path amplitude to subtract the common phase shift In this study, the optical AGC circuit is developed by means of a motor-driven variable-density attenuator.
