This research suggests that the regulation, design and improvement of domestic and international ambulances so that make the basis for the future ambulance in Korea. It is true that the diversification of current disasters, increasing elderly population, the increase in emergency patients, due to the lack of effective transfer system, emergency vehicle's performance problem, and the aging of ambulances cause have difficulty in providing effective emergency services in domestic country. Therefore, in order to improve the effectiveness of ambulance, the history of ambulance, other relevant provisions include international, design and directions to be improved were investigated, and also research directions of the ambulance are suggested in domestic country. In this research, suggests the following conclusions to improve domestic ambulance 1. Through standardization of the spacing and location of an ambulance is needed to maximize the treatment room. 2. The interior of the ambulance design for hygiene and infection control should be included. 3. Stretcher and equipment are designed to be fitted to each other should be standardized. 4. Especially during transfer maintain the road, noise, vibration, and shock-absorbing function to emphasize the importance. 5. The improvement of ergonomic design is necessary for the possibility of applying to many people.

Currently, accreditation within medical education is a priority on the agenda for many countries worldwide. The World Federation for Medical Education's (WFME) launch of its first trilogy of standards in 2003 was a seminal event in promoting accreditation within basic medical education (BME) globally. Parallel to that, WFME also actively spearheaded a project to recognize the accrediting agencies within individual countries. The introduction of competency-based medical education (CBME) with the two key concepts of "entrusted professional activity" and milestones has enabled researchers to identify the relationship between patient outcomes and medical education. Recent data driven by CBME has been used for the continuous quality improvement of trainees and training programmes as well. The goal of accreditation has shifted from the single purpose of quality assurance to balancing quality assurance and quality improvement. Even though there are a plethora of types of postgraduate medical education (PGME), it may be possible to accredit resident programmes on a global scale by adopting the concept of CBME. In addition, the alignment of the accreditation for BME and PGME, which center on competency, will be achievable. This argument may extend the possibility of measuring the outcomes of the accreditation itself against patient outcomes as well. Therefore, evidence of the advantages of costly and labor-consuming accreditation processes will be available in the near future and quality improvement will be the driving force of the accreditation process.

Objectives: A 54-year-old advanced gastric cancer patient developed severe fluid retention after docetaxel chemotherapy, at cumulative dose of $930mg/m^2$, with no improvement using diuretics or prophylactic glucocorticoids. Consequently, he changed chemotherapy regimen from docetaxel to paclitaxel. After he treated with herbal decoction Bangkihwangki-tang (BHT), which is widely used to treat several symptoms including edema in traditional Korean medicine, docetaxel-induced fluid retention (DIFR) was significantly improved along with associated symptoms, such as peripheral edema, pleural and pericardial effusion, pain, scleroderma, and hypoesthesia. As the symptoms were relieved, his performance status and ambulatory ability were improved. During herbal treatment, he continued chemotherapy without any problems and didn't show any adverse events related to herbal medicine. Although there is possibility of natural improvement progress after withdrawal of docetaxel, he showed shorter recovery period and significant improvement despite of severity of initial symptoms.

The possibility of application of membrane type immobilized adsorbent to the fed-batch or perfusion culture system with anchorage-independent cells as well as batch system was investigated. The improvement in cell density and cell viability due to the combination of immobilized adsorbent with each culture system was evaluated for the investigation, and the optimum culture system employing immobilized adsorbent system was suggested based on the results. It was observed that the system with immobilized adsorbent showed better cell growth and cell viability than that without immobilized adsorbent in every operation system of batch, fed-batch, and perfusion. In case of batch system, 200% improvement of maximum cell density was observed in the system where ammonium chloride was added on purpose. And 50% improvement of maximum cell density was observed in the fed-batch system where ammonium ion accumulates significantly, while small increase in maximum cell density was observed in the perfusion system where dilution of waste byproducts exists. Especially, the fed-batch system showed the most significant improvement on cell growth because both compensation of nutrient and removal of ammonium ion occurred simultaneously in the system. Therefore a combined system of immobilized adsorbent and fed-batch operation could be suggested as an optimum system with in situ removal of ammonium ion.

1. Objective: The aim of this study was to report significant improvement of tinnitus and insomnia after treatment with Cheongsimyeonja-tang in a Taeeumin patient with Idiopathic Sudden Sensorineural Hearing Loss(SSHL) that accompanied with Tinnitus. 2. Method: We measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Visual Analogue Scale(VAS) and Tinnitus Handicap Inventory(THI) were also used to assess tinnitus objectively. 3. Result: There was no improvement in pure tone audiometry by Siegel's Criteria. However, VAS score was decreased from 10 to 1 and THI score was also decreased from 74 to 48. 4. Conclusion: A patient with SSHL, who has little possibility of recovery of hearing loss, was treated with Cheongsimyeonja-tang in a short period and significant improvement in tinnitus and insomnia was observed. We consider that consistent treatment of Cheongsimyeonja-tang can contribute to improve the hearing loss.

With the increase of steel production research interest on the recycling of slag as a by-product also increases steadily. Currently in Korea a lot of researches on blast-furnace slag have been made. However, the researches on the steel slag have been rarely made. Also, a research of steel slag, especially the use of oxidation furnace slag as aggregates for concrete progress, is performing actively, but the research results on the furnace slag are almost nothing. Recently, the research about the furnace slag as backfill material and embankment material confirmed the possibility of the clay soil amendment. Therefore, the object of this study is to review the possibility as civil engineering materials for soil improvement and to find the optimum mixture ratio of furnace slag. This research analyzed the ingredient component of the reduced slag by SEM, XRF, XRD tests and examined the strength increase using unconfined compression tests when the clay and reduced slag are mixed each other. Through this test, the definite strength increase is confirmed according to the mixture of the reduced slag and the possibility of soil improvement is also confirmed based on this result. The object of the study is both utilizing the by-product for civil engineering purpose and effective recycling by the application of the furnace slag for soil improvement.

Purpose: First, this paper suggests an alternative approach to find optimal portfolio (stocks, bonds and ESG stocks) under the maximizing utility of investors. Second, we include ESG stocks in our optimal portfolio, and compare improvement of welfares in the case with and without ESG stocks in portfolio. Methods: Our main method of analysis follows Brennan et al(2002), designed under the continuous time framework. We assume that the dynamics of stock price follow the Geometric Brownian Motion (GBM) while the short rate have the Vasicek model. For the utility function of investors, we use the Power Utility Function, which commonly used in financial studies. The optimal portfolio and welfares are derived in the partial equilibrium. The parameters are estimated by using Kalman filter and ordinary least square method. Results: During the overall analysis period, the portfolio including ESG, did not show clear welfare improvement. In 2017, it has slightly exceeded this benchmark 1, showing the possibility of improvement, but the ESG stocks we selected have not strongly shown statistically significant welfare improvement results. This paper showed that the factors affecting optimal asset allocation and welfare improvement were different each other. We also found that the proportion of optimal asset allocation was affected by factors such as asset return, volatility, and inverse correlation between stocks and bonds, similar to traditional financial theory. Conclusion: The portfolio with ESG investment did not show significant results in welfare improvement is due to that 1) the KRX ESG Leaders 150 selected in our study is an index based on ESG integrated scores, which are designed to affect stability rather than profitability. And 2) Korea has a short history of ESG investment. During the limited analysis period, the performance of stock-related assets was inferior to bond assets at the time of the interest rate drop.

The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.
