Recently, many countries are tightening a variety of policies and controls with great efforts to reduce emission of GHGs(Greenhouse Gases) as concern for climate change heightens. The purpose of the study is to provide guidelines for planning and evaluate element and evaluate housing development. The elements are also assorted into 6 sections and 30 planning elements were drawn from them. It is drawn to 6 sections, 27 categories, 31 evaluation elements except cultural and perceptual aspects unrelated to planning elements from these elements. Case analysis has shown that most of planning elements were applied because these cases obtained environment-friendly certification in the country. Followings are the common characteristics. Firstly, it showed that application of planning element in all cases is excellent. Secondly, the case with excellent application of elements related with energy and application degree obtained excellent degree i environment-friendly certification in the country. Finally, application of planning elements related with renewable energy was in poor condition in all cases. With the utilization of SBTool, the evaluation results about planning elements of housing complex of Carbon emissions-reduction type showed that CASE-A obtained 11.17 points and CASE-B obtained 9.24 points. In the case of renewable energy section, it was confirmed that the evaluation doesn't work well. As a result, changes of planning elements affect environment-friendly extent. It was confirmed that accessibility to housing complex of Carbon emissions-reduction type could change. Estimated result of Amount of Carbon emission showed that annual energy consumption per each family of CASE-A is $4,269,964MJ/m^2$, as a result of which, Carbon emission is $234,815kg/m^2$. And annual energy consumption per family of CASE-B is $4,197,563MJ/m^2$, as a result of which, Carbon emission is $214,584kg/m^2$. Application of planning elements in the aspect of housing complex of Carbon emissions-reduction type shows that the level for Carbon emissions-reduction is high level. And study with assessment from the draft should be followed.

Locally PDA has been utilized mainly as an alternative way of preforming pile loading tests. More than 30 units of PDA's are believed to be operating in Korea. It is true that PDA can provide useful information regarding bearing capacity, integrity, hammer performance, time effect, etc. However it is also true that inappropriate execution of PDA could result in harmful effects for the safety of the superstructure or causing delay in the construction process. In this paper several cases of inappropriate application of PDA are introduced. Most of the problems seemed to be caused by unqualified personnel who carry out testing and analysis. From the evaluation of the cases a proposal has been made for the proper application of PDA.

Active application of auger-drilled piling is expected in Korea considering its advantage in noise and vibration problems against driven piling and its cost-effectiveness in comparison to the cast in-situ piling. The current design practice being used in Korea is adopted from the Japanese one, however the equipment and construction procedure is modified for the geotechnical conditions and construction circumstances in Korea. Therefore there is an urgent need for the establishment of the rational design criteria for the auger-drilled piling in Korea. As the preliminary work for the establishment, this paper presents the current practice in Korean railway constructions. Design criteria of Korea Railway Network Authority are introduced and its characteristics and the problems are described. Application cases of auger-drilled pile to railway construction are introduced as well.

Morphing method, one of classic image processing algorithms, has been used in various application fields. The motivation of this work is to investigate its applicability in consideration to geo-spatial data including airborne or space-borne images. For this purpose, the Beier and Neely morphing algorithm is tentatively implemented in the form of a prototype with user interface. As the results, this feature-based morphing with paired image sets can be used for general users: image simulation using two or more images and construction of color-blending image between source image and destination image in different types. Some simple application cases were demonstrated. This scheme is the simple and useful approach for those who want to utilize both geo-spatial data sets and airborne/space-borne image sets.

When starting a new project, generally similar existing projet are searched. As Building Modeling Information(BIM) has short history and experience, the dependence on similar project is high. Small and medium sized design companies are depending on website search tool for information of BIM project besides companies maintaining the Database(DB) from lots of project experience. However, the information level and contents provided by websites differ drastically from each other which makes it difficult to utilize the information and apply cases. Furthermore, the different classification system of the sites makes the situation even worse. Therefore, we collected and analyzed over 100 BIM cases from 18 global websites, to develop a system for BIM case application. Result showed that over 90% of our subject pool provided basic information including the construction type, characteristics of the client (public/ private), location of the project, and detailed information such as primary usage. Moreover, the reasons for applying BIM where to solve problems of geometric design, building system like MEP and construction. Furthermore, there was a contrast between cases conducted only within Korea and cases conducted with other countries. While there was almost always helpful information regarding the administrative steps for Korean BIM cases, there was close to no information for projects carried out outside of Korea. These results could contribute to verifying the trend of information provision of the websites for BIM projects data, and this is believed to be helpful for developing an application system for BIM cases which have an organized information provision system and level as well as for bench marking.

This study analyzed the registration of patent and utility models by fashion firms in Korea. A total of 2,291 registration cases of IPC A41B-H from the period of 1996 to 2009 were collected by KIPRIS of the Korean Intellectual Property Organization (KIPO). All cases were analyzed by year to review the longitudinal trend and 481 cases of IPC A41B (shirts, underwear, baby linen, and handkerchiefs) and 1088 cases of IPC A41D (outerwear, protective garments, and accessories) were analyzed by content (provided benefit type and developing method), by detailed product items and the characteristics of the applicant. The results of this study were as follows: 1) Registration of IPC 41 increased steeply by the year (especially since 2006) and the patent registrations increased more than those in the utility model. 2) Analyzing the application content of A41B on the basis of benefit showed that 75% were to provide new functions and the rest were for health. In terms of the developing method, 83% of benefit provided by the application were by design development, 11.2% were by material, and the rest was by process, In the cases of IPC A41D, 23.6% were for safety and protection. In terms of the developing method, the process and material development were more frequently adopted than in the cases of A41B. 3) The major product types of A41B were socks, underwear, and infant wear, whereas gloves and parts of clothing were major items in A41D. 4) In terms of the characteristics of the applicant, registration by firms was greater for patents than for utility models and registration by foreigners increased in 2006 due to the complete opening of the retail market. 5) Fifteen universities registered for a total 57 cases and major applications were for IT related clothing or high-tech protective items.

Purpose: The aim of this study is to investigate current status, indications, and complications of hyperbaric oxygen therapy. Methods: A retrospective investigation of patients who underwent hyperbaric oxygen therapy at a university medical center from September 2004 to August 2013 was conducted based on patients' medical records and results of an email survey for 99 emergency centers. Results: During the study period, a total of 233 patients underwent hyperbaric oxygen therapy. Indications for hyperbaric oxygen treatment of illness or injury were as follows: 1) 151 cases of acute carbon monoxide poisoning(65.4%), 2) flap wound management, including 42 cases(18.2%), 3) skin care transplanted, including 23 cases(10.4%), 4) Burger's disease, including 5 five cases(2.1%), respectively. Total application time$^*$ frequency was 1,088 and total time was 1,239 hours. Among 233 patients who underwent hyperbaric oxygen therapy, 32 patients(13.7%) had complications: 1) otalgia in 21 cases(9.0%), 2) mastoiditis?in six cases(2.6%), 3) hemotympanum in five cases(2.1%), respectively. There were only 8 emergency centers that currently had an operational hyperbaric oxygen chamber in 77 emergency centers(10.4%). Conclusion: Indications identified through this study showed difference from current indications worldwide. It seems necessary that physicians' perception regarding application of hyperbaric oxygen therapy for more indications be changed and improved. A hyperbaric chamber capable of providing respiratory assistance and intensive care is also needed. A good network for sharing treatment experiences and a specialized team for administration of hyperbaric oxygen therapy is also required.

Several companies have migrated their existing monolithic web applications to microservice architectures. Consequently, research on the identification of microservices from monolithic web applications has been conducted. Meanwhile, the use-case model plays a crucial role in outlining the system's functionalities at a high level of abstraction, and studies have been conducted to identify microservices by utilizing this model. However, previous studies on microservice identification utilizing use-cases did not consider the components executed in the presentation layer. Unlike existing approaches, this paper proposes a technique that considers all three layers of web applications (presentation, business logic, and data access layers). Initially, the components used in the three layers of a web application are extracted by executing all the scenarios that constitute its use-cases. Thereafter, the usage rate of each component is determined for each use-case and the component is allocated to the use-case with the highest rate. Then, each use-case is realized as a microservice. To verify the proposed approach, microservice identification is performed using open-source web applications.

Background: Prolonged usage of extracorporeal membrane oxygenation (ECMO) may induce multi-organ failure. This study is aimed to evaluate prognostic factors in the patients with ECMO. Also, the prognosis of ECMO with Kidney Injury Network Scoring system is studied. Materials and Methods: From May 2005 to July 2011, 172 cases of ECMO were performed. The cases of perioperative use of ECMO were excluded. Renal failure patient and younger than 15 years old one were also excluded. As a result, 26 cases were enrolled in this study. Male patients were 15 (57.7%), and mean age was $56.57{\pm}17.03$ years old. Demographic data, ECMO parameters, weaning from ECMO, and application of continuous renal replacement therapy are collected and Acute Kidney Injury Network (AKIN) scores were evaluated just before ECMO and day 1, day 2 during application of ECMO. Results: Venoarterial ECMO was applied in 22 cases (84.6%). The reasons for applications of ECMO were cardiac origin in 21 (80.8%), acute respiratory distress syndrome in 4, and septic shock in 1 case. Successful weaning from ECMO was achieved in 15 cases (57.7%), and survival discharge rate was 9 cases (34.6%). Mean duration of application of ECMO was $111.39{\pm}54.06$ hours. In univariate analysis, myocarditis was independent risk factors on weaning failure. Using the receiver operating characteristic curve, level of hemoglobin on 24 hours after ECMO, and base excess on 48 hours after ECMO were showed more than 0.7. AKIN score was not matched the prognosis of the patients with ECMO. Conclusion: In our study, the prognosis of the patients with myocarditis was poor. Hemoglobin level at first 24 hours, and degree of acidosis at 48 hours were useful methods in relating with prognosis of ECMO. AKIN scoring system was not related with the prognosis of the patients. Further study for prognosis and organ injury during application ECMO may be needed.

The most common cause of spontaneous pneumothorax is a ruptured bleb, which occurs mostly in young patients and they are usually treated by tube thoracostomy. Recurrence frequently occurs and these patients require some form of surgical intervention. From March 1990 to February 1994, we have experienced 19 cases of recurrent pneumothorax in 16 patients among 347 patients who underwent 423 surgical interventions. The name of first operation after thoracotomy were bullectomy in 4 cases, bullectomy and pleurodesis in 3 cases, bullectomy, pleurodesis in addition to application of tissue sealant in 1 case. Thoracoscopic operations were performed as follows: bullectomy in 2 cases,electroablation plus tissue sealant in 4 cases, electroablation, tissue sealant and pleurodesis in 1 case,and in 4 cases, only tissue sealant was applied. The average age of patients are 21.5 years, and bilaterally operated patients and patients. who received tissue sealant or tissue sealant plus electrocauterization only had higher incidence of recurrence. The patients who needed chest tube insertion longer than 5 days after the first operation were 52.6 %, and 82.3 % recurred within one month of the first operation.
