Introduction: Although most prostate cancers initially respond to castration with luteinizing hormonereleasing analogues or bilateral orchiectomy, progression eventually occurs. Based on the exciting results of several randomized controlled trials (RCTs), it seems that patients with metastatic castration-resistant prostate cancer (mCRPC) might benefit more from treatment withabiraterone. Therefore we conducted a systematic review to evaluate the efficacy and toxicity of abiraterone in the treatment of mCRPC. Methods: Literature was searched from Embase, PubMed, Web of Science, and Cochrane Library up to July, 2013. Quality of the study was evaluated according to the Cochrane's risk of bias of randomized controlled trial (RCT) tool, then the Grading of Recommendations Assessment, Development and Evaluation (GRADE) System was used to rate the level of evidence. Stata 12.0 was used for statistical analysis. Summary data from RCTs comparing abiraterone plus prednisone versus placebo plus prednisone for mCRPC were meta-analyzed. Pooled hazard ratios (HRs) for overall survival (OS), radiographic progression-free survival (RPFS) and time to PSA progression (TTPP); Pooled risk ratios (RR) for PSA response rate, objective response rate and adverse event were calculated. Results: Ten trials were included in the systematic review; Data of 2,283 patients (1,343 abiraterone; 940 placebo) from two phase 3 trials: COU-AA-301 and COU-AA-302 were meta-analyzed. Compared with placebo, abiraterone significantly prolonged OS (HR, 0.74; 95% confidence interval [CI], 0.66 to 0.84), RPFS (HR, 0.59; 95% CI, 0.48 to 0.74) and time to PSA progression (HR, 0.55; 95% CI, 0.43 to 0.70); it also significantly increased PSA response rate (RR, 3.63; 95% CI, 1.72 to 7.65) and objective response rate (RR, 3.05; 95% CI, 1.51 to 6.15). This meta-analysis suggested that the adverse events caused by abiraterone are acceptable and can be controlled. Conclutios: Abiraterone significantly prolonged OS, RPFS and time to progression patients with mCRPC, regardless of prior chemotherapy or whether chemotherapy-na$\ddot{i}$ve, and no unexpected toxicity was evident. Abiraterone can serve as a new standard therapy for mCRPC.

Variation of soil properties is studied by permeating injection of chemical grouts, such as cement type, water-glass type and acrylamide type, to the same soil samples with different densities. Moreover, injection tests using specially prepared equipments of 1.0 shot system and 1. 5 shot system are attempted to investigate permeating injection effects in highly compacted soil and in the presence of ground water. The main factor which causes the improvement of cut-off effect and shearing strength is the cohesion of soil. The strength in the loose state is fundamentally governed by the membrane cohesion, meanwhile, in the loose state is governed by the structural cohesion. Injection effects under the ground water flow is considerably decreased, and effective gelling ratio of approximate 45~80% is observed by variation of velocity and gel time, besides grading of injection materials has high relation with permeation and traveling length but has little relation with effective gelling ratio. Permeating injection effects, such as gelling scope, gelling strength in highly compaoted soil conditions can be confirmed by penetration resistance diagram and iso-strength curve.
Purpose: The aim of this retrospective study was to evaluate the relationship between appearance and size of bone bruise and severity of anterior cruciate ligament (ACL) injury with magnetic resonance imaging (MRI), furthermore, to identify the mechanism of ACL injury by analyzing the footprint of bone bruise. Materials and Methods: Sixty-five subjects who was taken an MRI within 6 weeks after acute ACL injury were studied. All MRI showed ACL injury and associated bone bruises. Bone bruises were analyzed using Costa-Paz classification based on appearance and location and also scored using Kornaat bone bruise grading system based on size and location. The severity of the ACL injury was graded using a 4-point system (ie, grade 0-3) with oblique coronal MRI. Results: There was statistically significant correlation between Costa-Paz classification of bone bruises in lateral femoral condyle and grade of ACL injury. There were more type 2 lesions in partial tear group (grade 1, 2), however, type 3 lesions of Costa-Paz classification in complete tear group (P=0.037). Significant positive correlations were observed between Kornaat total bone bruise score and grade of ACL injury (P=0.014). Most common ACL injury mechanism was pivot shift injury. Other mechanisms were clip valgus injury, phantom foot injury, and hyperextension injury. Conclusion: It is highly suggested that appearance and size of bone bruise is related to severity of ACL injury after acute ACL injury. The foot print of bone bruise provides valuable clues to identify ACL injury mechanism.
The objective of this study was to assess the external and internal quality traits of eggs in wholesale egg market in Colombo, Sri Lanka and the effect of storage period in egg quality traits in the same market after receiving the eggs. First, a total of 482 fresh eggs were randomly collected from the above market and external egg quality traits were determined and recorded according to the definitions given in the Specification for Chicken Egg SLS 959:1992. After that, a total of 288 fresh eggs were randomly collected and various external and internal egg quality traits were measured and recorded according to the standard procedures over a storage period of 1, 3 and 5 d after receiving the fresh eggs to the wholesale market. Information about the shops was also collected using a pretested questionnaire. Using the recorded data, shape index, Haugh unit, albumen index and yolk index were calculated for each egg. Average weight, width, length and shape index of the eggs in the sample was 59.96 g, 4.33 cm, 5.78 cm and 75.03, respectively. Average shape index value was much closer to the standard value of 74. From the total sample 80.5% eggs had a normal and sound shape. However only 60.37% of the eggs are in the desirable quality range specified in SLS 959:1992, when the overall shell quality of the sample is considered based on shell cleanliness, defects and shape. The results of the current study indicated that eggs had significant (p<0.05) deterioration of all internal quality parameters tested with increasing storage time. However the effect was not significant (p>0.05) between the storage periods of 3 and 5 d after receiving eggs except for yolk color and yolk height. Desirable category of eggs had reduced and rejections had increased with the storage period. Main problems associated with the particular market were less space availability, higher percentages of dirty eggs, unavailability of proper packaging materials, no standard packaging system for eggs, and not implementing a standard grading system for eggs. Therefore the results of this study suggest that proper egg handling and storage conditions such as low temperature storage may be implemented to increase the proportion of desirable quality eggs in the above market.

Objectives : The purpose of this study is to establish the basis of the assessment tools that can be used for the diagnosis and assessment of skin diseases by reviewing the present status of the assessment tools used in domestic and overseas traditional medicine papers for the past five years. Methods : This study is based on analysis of papers on clinical trials about atopic dermatitis, psoriasis, acne, urticaria published from 1st July 2013 to 30th June 2018. The papers were searched from Oriental Medicine Advanced Searching Integrated System(OASIS), Korean Traditional Knowledge Portal(KTKP), Pubmed, MEDLINE. Results : 40 articles on atopic dermatitis, 34 articles on psoriasis, 26 articles on acne and 10 articles on urticaria were selected. Among them, 38 articles(90%), 20 articles(85%), 22 articles(85%) and 5 articles(50%) used assessment tools in order. Conclusions : SCoring Atopic Dermatitis(SCORAD), objective SCORing of Atopic Dermatitis index(OSI), Eczema Area and Severity Index(EASI) were used in studies on atopic dermatitis. In the case of psoriasis, The Psoriasis Area and Severity Index(PASI) was used in most papers. In the study on acne, most of Korean papers used Korean Acne Grading System(KAGS), but in the overseas papers, various assessment tools were used. In the case of urticaria, the rate of use of the assessment tool was the lowest, but the assessment tool used was unified by Urticaria Activity Score(UAS). Since skin diseases can cause stress and a decrease in quality of life, the quality of life should be taken into account when evaluating treatment effects.
As the population is getting older, medical expenses amount of the whole is keep increasing. So, the pressure of the finances, Health Insurance, Medical Care Assistance Act and etc, is getting higher. The share of healthcare-expense is increasing due to elderly illness. And it became a social problem; we analysed present state of senior healthcare in South Korea-looked into current laws and policies, and found problems. We tried to suggest improvements that drew from the current state of foreign country senior healthcare of those problems. For the result, we found the problem in relevant-law system of senior healthcare guarantee. In this study, we proposed the ways to qualitatively upgrade of medical standard that considered on elderly' features: the strengthened guarantee for healthcare, financial secure for long-term convalescence benefit, linking and functional reinforcement for elderly welfare and long-term convalescence insurance, the solution for overlapped laws about convalescence in long-term convalescence insurance and elderly welfare, a betterment of grading, and a home service consolidation. We need to secure right amount of emergency medical service budget, and effective management system for the improved level of senior severely emergency medical service. Furthermore, we suggested that South Korea needs to legislate [The Law for Senior Medical Secure] to respond to rapidly increasing senior healthcare fee.
The Japanese colonial authority investigated and institutionalized Korea's cultural properties for the purpose of governance. This process was conducted by Japanese officials and scholars, and systematized after making some changes. The Reservation Rule (1916) and the cultural properties designated in 1934 were actually the starting point for Korea's current cultural property policy. In the view of lineup of 'committee' that consider all of cultural property and changing of 'cultural property list', this study discusses the cultural property policy implemented by Joseon's Government-General, which can be summarized as follows. First, Joseon's Government-General formed a committee (Preservation Society) to formulate the cultural property policy, and had the policy implemented by appointing Governor officials who accounted for more than half the total number of officials of the institution. Although some Koreans were concerned about this, they had no influence on the matter. Second, the cultural properties listed by Joseon's Government-General are divided into three periods according to the lists. The compilation of the first list was led by Sekino Tadashi, who represented the grading system (1909~1916); while that of the second list (1917~1933) was led by Guroita Gatsumi, who represented listing (1917~1933). Guroita Gatsumi tried to erase Sekino Tadashi's list by formulating the cultural property policy and the list - a situation that was revealed in the system and the actual contents of the list. The third list was made as a list of designated cultural properties in 1934. This list also reflected the results of Sekino Tadashi investigation of the important cultural properties at existing temples that had been excluded from the previous regulations (1934~1945). In this way, a basic framework for the listing of Korean cultural properties was established in 1934.

Technology evaluation is to assess the ability of technology commercialization entities to generate profits by using the subject technology, and domestic technology evaluation agencies have established and implemented their own evaluation systems. In particular, the recently developed technology evaluation model in the fields of marine and fishery does not sufficiently reflect the poor environment for technology development compared to other industries, so it does not pass the level of T4 rating, which is considered appropriate for investment. This is recognized as a challenge that occurs when the common evaluation indicators and evaluation scales used in other industries, and when the scoring system for T1 to T10 grading is similarly or identically utilized. Therefore, through this study, we intend to secure the appropriateness and reliability of the results of the comprehensive rating calculation by developing technology evaluation models and indicators that well explain the nine marine and fisheries industry classification systems. Based on KED and technology evaluation case data, AHP-based index weighting and Monte Carlo simulation-based rating system are applied and the results of case studies are verified. Through the proposed model, we aim to enhance the usability of R&D and commercialization support programs based on fast, convenient and objective evaluation results by applying to upcoming technology evaluation cases.
This study was conducted to investigate the facilities, cultivation, postharvest management, and distribution status of 27 cut chrysanthemum farms in Korea. The 60% of farms have cultivated the cut chrysanthemum using soil fertigation system in the PE plastic house. In Jeonnam and Busan provinces, Standard type of chrysanthemum was cultivated mainly than spray type of chrysanthemumJeoas. Most farms have been producing the rooted cuttings by plug system using cuttings self-propagated or purchased from the company, but farms in Jeonnam have been planting cuttings directly on cultivation bed. And the 66.6% of cut chrysanthemum farms have been pretreating with dipping in hot water or tap water after harvesting. Precooling was not performed on 70.4% of the farms, and precooling farms have been mainly conducted at temperature of $2-4^{\circ}C$. After harvesting, 70.4% of the farms stored the cut flowers at $2-4^{\circ}C$ for more than 48 hours to control the distribution volume. Cut chrysanthemum was graded mainly by individuals before distribution, and some export farmers have been conducting the cooperative grading. In distribution, all farms have distributed the cut flowers to the domestic markets, and 44.4% of these farms have been also exporting. The 63.0% of farms distributed to domestic market have been trading with flower auction sites.

Focusing high marble deposition, Hanwoo feedlot system uses high-energy diet over the prolonged fattening period. However, due to the individual genetic variation, around 40% of them are graded into inferior quality grades (QG), despite they utilized the same resources. Therefore, focusing on development of a nutrigenomic based precision management model, this study was to evaluated the response to the divergent selection on genetic merit for marbling score (MS), under different dietary total digestible nutrient (TDN) levels. Total of 111 calves were genotyped and initially grouped according to estimated breeding value (high and low) for marbling score (MS-EBV). Subsequently, managed under two levels of feed TDN%, over the calf period, early, middle, and final fattening periods following 2 × 2 factorial arrangement. Carcasses were evaluated for MS, Back fat thickness (BFT) and Korean beef quality grading standard. As the direct response to the selection was significant, the results confirmed the importance of initial genetic grouping of Hanwoo steers for MS-EBV. However, dietary TDN level did not show an effect (p > 0.05) on the MS. Furthermore, no genetic-by-nutrition interaction for MS (p > 0.05) was also observed. The present results showed no correlation response on BFT (p > 0.05), which indicates that the selection based on MS-EBV can be used to enhance the MS without undesirable effect on BFT. Ultimate turnover of the Hanwoo feedlot operation is primarily determined by the QGs. The present model shows that the initial grouping for MS-EBV increased the proportion of carcasses graded for higher QGs (QG1++ and QG1+) by approximately 20%. Moreover, there appear to be a potential to increase the proportion of QG 1++ animals among the high-genetic group by further increasing the dietary energy content. Overall, this precision management strategy suggests the importance of adopting an MS based initial genetic grouping system for Hanwoo steers with a subsequent divergent management based on dietary energy level.
