박영민,김수용,김기영,Park Young-Min,Kim Soo-Yong,Kim Ki-Young 한국건설관리학회 2004 건설관리 : 한국건설관리학회 학회지 Vol.5 No.5

건설 공사의 여러 관리 요소 중 일정관리는 매우 중요하다. 하지만 현재의 건설 프로젝트 일정관리 수준은 1950년대에 만들어진 PERT나 CPM을 반세기가 지난 지금까지 그대로 사용하고 있을 정도로 후진성을 면치 못하고 있다. 이런 PERT/CPM의 사용은 소요공기추정의 불확실성과 그 활동에 할당된 자원의 경합과 같은 여러 가지 문제들을 야기하고 있다. 따라서 본 연구에서는 기존의 일정관리 기법인 PERT/CPM의 단점을 보완하고 국내 건설공사의 일정관리 효율성을 증대시키기 위하여, 1997년에 개발된 새로운 일정관리 이론인 CCPM(Critical Chain Project Management)에 대한 소개와 함께, 가상의 교량건설 프로젝트를 대상으로 한 모의시험을 통하여 CCPM의 국내건설사업에의 적용 가능성을 검증 하였다. Construction work varies with the project types. However, the success of all project types depends upon three conditions i.e. schedule, quality and cost. If these three conditions are fulfilled, then project said to be successful. In this paper, scheduling of a construction Project has been dealt with the application of CCPM method. CCPM has been introduced as a new theory in construction industry in 1997 at the United States, but its application is still insufficient in domestic field due to the absence of systematic study, A simulation has been conducted in a Bridge construction project to validate the possibility of CCPM in order to complement PERT/CPM in construction field. The result of study shows that the CCPM could be effective to reduce the project time duration than existing PERT/CPM technique.

SOC 민간투자사업의 CM 업무 수행구조 제안

박영민,김대영,조훈희,김수용,Park, Young-Min,Kim, Dae-Young,Cho, Hun-Hee,Kim, Soo-Yong 한국건설관리학회 2006 건설관리 : 한국건설관리학회 학회지 Vol.7 No.4

정부는 재정 부담을 완화하면서 사회간접시설을 조기에 구축할 수 있는 SOC 민간투자사업 제도를 도입하여 적극 장려하고 있다. 민간투자사업의 비중은 2005년을 기준으로 전체 SOC 투자의 15%에 이를 만큼 크게 성장하였으며 이러한 성장세는 당분간 지속될 것으로 판단된다. 하지만 화려한 양적인 성장에 비해서 사업의 효율성, 생산성, 사업 규모의 적정성 등에 관한 문제점들이 지적되고 있다. 이에 본 연구에서는 민간투자사업에서 나타나고 있는 문제점을 도출하고, 이러한 문제점의 해결 방안으로 민간투자사업에 CM을 적용하는 방안을 제시하였다. 제시한 방안을 통하여 단기적으로는 SOC 민간투자사업의 효율성과 생산성을 증대시키는 효과를 얻을 수 있을 것이며, 장기적으로는 CM 적용의 좋은 사례(best practice)로 건설 산업 전반에 CM이 도입되는 촉매제가 될 것이다. The Korean government is encouraging positively PIP(private infrastructure project) to relieve financial burden and get the facilities in time. The portion of the PIP has grown rapidly into 15% of the whole SOC(Social Overhead Capital) projects. It is estimated that the growth will continue for the present. However, there are still rising problems on efficiency of the project and productivity, properness of the project scale are pointed against surprising growth. In this study, we analyze underlying problems of private infrastructure investment project and suggest CM Models to relieve the problems. To verify the validity of the suggested models, a survey has been conducted through questionnaires and analyzed the taste of the stakeholder. The owner-support Model is chosen as the practical model to apply in time. By applying the suggested model to PIP, it is possible to enhance the efficiency and productivity of the project.

Purpose: To analyze the morphology and density of corneal tissue in patients with bullous keratopathy using in vivo confocal microscopy (IVCM).<br /> Case summary: Four eyes of 4 patients with clinically diagnosed bullous keratopathy were examined using IVCM. Cross-sectioned corneal images of the corneal epithelium, Bowman’s layer, stromal layer, Descemet’s membrane, and endothelium were evaluated. In bullous keratopathy patients, the outline of corneal epithelial wing cells was blurred. Several hyper-reflective whitish dots were found at the corneal epithelial level and a reduction in the density and thickness of the corneal nerves was observed. There was also a reduction in the density of the stromal keratocytes. The outline of the stromal keratocytes was blurred. Some keratocytes resembled myofibroblast. The hypo-reflective vertical strands were observed in the stroma adjacent to the Descemet’s membrane. Endothelium showed hyper-reflectivity with associated increased endothelial pleomorphism and polymegathism.<br /> Conclusions: In patients with bullous keratopathy, IVCM showed tissue edema in the corneal epithelium, stroma, and endothelium. Hyper-reflectivity appearances were noted due to the increase in the metabolic rate of the cells or extracellular matrix accumulation. Corneal endothelium showed morphological changes.<br /> J Korean Ophthalmol Soc 2013;54(12):1923-1928

Purpose: To compare the clinical outcome of silicone tube intubation according to the tie methods. Methods: Eighty-eight eyes of 87 patients who underwent silicone tube intubation were divided into two groups based on the tie method: a silicone silastic sheet group (Group 1, n=59) and a nylon 6-0 suture knot group (Group 2, n=29). The two groups were compared according to their success rates, recurrence rates and complications. Results: No significant difference was found in the success rate between the two groups (83.0% in Group 1 and 82.7% in Group 2). However, Group 2 showed a significantly higher rate of postoperative complications than Group 1. In Group 1, 5/59 (8.4%) eyes had ocular irritation, 2/59 (3.4%) eyes exhibited tube prolapse, conjunctivitis, corneal erosion, and dacryocystitis and 1/69 (1.6%) eyes had a punctal slit after intubation. In Group 2, 3/29 (10.3%) eyes had ocular irritation, 2/29 (6.9%) eyes exhibited tube prolapse, conjunctivitis, a punctal slit, and dacryocystitis, and 1/29 (3.4%) eyes showed corneal erosion, or a granuloma after intubation. A recurrence of symptomatic tearing was found in 6/59 (10%) eyes in Group 1 and 3/29 (10%) in Group 2. Conclusions: In silicone tube intubation of incomplete NLD obstruction, the usage of silicone silastic sheets to tie both ends of the silicone tube produced a lower complication rate and a higher success rate than that of the suture knot group. Lower tension on the nasolacrimal passage in the silicone silastic sheet group allows for a significantly lower rate of punctal slit development. Therefore, the method of using silicone silasitic sheets can be considered useful in the treatment of NLD obstruction.

LCC를 고려한 BOX구조물 뒷채움 재료의 경제성 분석

박영민,김수용,Park, Young-Min,Kim, Soo-Yong 한국건설관리학회 2009 한국건설관리학회 논문집 Vol.10 No.6

경량기포혼합토는 경량성으로 인해 구조물 등에 작용하는 하중이 저감되어 연약지반의 뒷채움 재료로 사용되지만, 일반토사에 비하여 초기시공비용이 많이 소요되어 아직 국내에서는 많이 적용되고 있지 않다. 주로 뒷채움 재료는 초기시공비가 적게 소요되는 일반토사를 사용하고 있으나, 일반토사의 덧씌우기 공법은 횟수가 증가함에 따라 사용연수가 감소된다. 특히 연약지반에 설치된 BOX구조물이나 교대 뒷채움 인근의 단차 발생 시 덧씌우기 공법은 일시적인 대체공법은 가능하지만, 덧씌우기 두께에 대한 하중만큼 추가 하중이 발생하게 되므로 결국 단차에 대한 해결책은 되지 못한다. 따라서 본 연구에서는 BOX구조물 뒷채움 재료인 일반토사와 경량기포혼합토의 두 가지 대안에 대하여 LCC 분석을 실시하고 경제적 측면에서 보다 합리적인 의사결정을 할 수 있는 경제성 분석을 제시하고자 하였다. 그 결과 경량기포혼합토가 일반토사에 비해 초기시공비용은 많이 소요되지만 유지관리 측면에서는 비용이 더 적게 소요되어 경제성을 확보할 수 있는 것으로 분석되었다. The lightweight bubble mixture soil is used for soft ground rear-filling material by applying reduced weight on structure. However, comparing with the general soil, it is not applied in domestic because of initial phase cost of construction. General soil, which has lower initial phase cost is usually used for rear-filling, but the use of overlay method of general soil is reduced as the number of layers increases. Especially box structure placed in soft ground or the overlay method when gap near pier rear-filling can be replaced with temporary alternative method, however, it can't be a solution to gap by generation of extra weight of thickness of overlaying. Therefore, execute LCC analysis of two alternative-the general and the lightweight bubble mixture soils, which are rear-filling material of box structure- and present economical analysis in order to make resonable decision from the economics. As a result, although the lightweight bubble mixture soil takes higher initial phase cost than the general soil, it has been analyzed to procure economical efficiency by having less cost of maintenance.

피부과 외래환자에서 아토피피부염의 상대 빈도와 임상적 특징 및 검사 소견에 관한 연구

박영민,박홍진,김태윤,김정원 ( Young Min Park,Hong Jin Park,Tae Yoon Kim,Chung Won Kim ) 대한피부과학회 1997 大韓皮膚科學會誌 Vol.35 No.1

Background : Atopic dermatitis(AD) is a common disease, and population-based studies indicate that the frequency of AD has increased substantially during recent decades. However, there have been few studies on the hospital based relative frequency, and clinical and laborat,ory findings of AD in Korea. Objective : The presenl study was aimed to elucidate the relative frequency of AD on the outpatient base, and to investigate the clinical manifestations and immunological laboratory findings. Methods : Our study was designed by analysing outpatients with AD via physical examination, questionnaires and immunological investigations such as skin prick tests, Multi test CMI, and measurernent of eosinophil counts, total IgE, Derrnatophagoides pteronyssinus-specific IgE and eosinophil cationic protein(ECP). Results : The results were as follows : 1. The relat,ive frequen:y of AD on the hospital base in 1995-1996 was 8.6%. 2. The mean age of onset was 3.36 years. 57.3% of the patients had their onset of eczema by the age of 1 year, 65.5% by 2 years and 83% by 5 years. The most common site at the onset was the face followed by antecubital area, popliteal area, neck, and trunk. 3. The predilection site on physical examination were the face, neck, antecubit,al area, popliteal area and trunk in decreesing order. 4. Concomitant allergic rhinitis, keratoconjunctivitis and asthma were present in 2~3.4%, 14.1%, and 9.5% of patients with AD, respect.ively, whereas pure AD was present in 34.1%. 5. Family history of atopy was observed in 60.5% of AD patient.s. 6. The most frequent ninor fea~ture of AD was xerosis followed by perifollicular accentuation, allergic shiner, cheilitis, imitation allergy, palrnar hyperlinearity and molluscum cantagiosum. 7. Seasonal aggravation was found in 86.8% of patients with AD, especially in summer and winter, The rnost significant aggravating factors were wools followed by sweating, heating, dryness, excessive bat.hing and emotional stress. 8. Abnormal levels of .osinophils, total IgE and ECP were seen in 44.8%, 78.9% and 31.7% Of patients with AD, respec.ively. 9. Cell mediated immunty was decreased in 68.2% of patients with AD. 10. Positive reactivity( at least rnore than one alle~rgen) in the skin prick t,est was noted in 76% of pat,ients with AD and the most popular 8 allergens were D. pteronyssinus, D. farinae, cat fur, M4 mixed threshing dust., dog hair, mugwort pollen, H3 tree pollen and birch pollen. 11. The specific IgE aritibodies to D. pteronyssinus(>+1) were found in 72.3% of AD patients and correlated with the r esults of the skin prick test in 76%. Conclusion : The hospi al-based relative frequency of AD investigated in our study tends to be increased. As the clinica featu~res and laboratory findings of AD might be influenced by genetic, environrnental and psychological factors, the systernic evaluation of patients with AD will be needed (Kor J Dermatol 1997;35(1): 96-106)

Purpose: In this study we analyzed and objectified the characteristics of the Avellino corneal dystrophy patients considering disease severity using in vivo confocal microscopy (IVCM). Methods: Each corneal layer of 36 eyes in 18 patients with Avellino corneal dystrophy was examined using IVCM (ConfoScan 4.0, NIDEK, Co. Ltd., Albignasego, Italy). Patients were classified into 3 groups based on disease severity (mild, moderate, or severe). Results: In the mild group, hyper-reflective granular deposits without dark shadows were observed in the anterior stroma. As the disease progressed, corneal deposits were also found at the posterior stroma and epithelium, and clusters of hyper-reflective corneal deposits resembling stromal opacity were noted. The range of corneal deposits measured using Z-scan optical pachymeter was 111.14 ± 30.95 um in the mild group, 157.47 ± 25.00 um in the moderate group, and 193.42 ± 52.23 um in the severe group (p < 0.05). Conclusions: The origin of the corneal deposits in Avellino corneal dystrophy may be related to corneal stromal cells and distributed from the corneal epithelial layer to the stromal layer. IVCM might be useful for the standardization of disease severity by digitalizing the range of deposits. J Korean Ophthalmol Soc 2014;55(3):361-367
