This study analyzed the current status of registered patents related to food tech in Korea and Japan. Using the patent information search services of Korean and Japanese Patent Offices, patents registered during the past 10 years from January 1, 2005 to December 31, 2015 were searched with the following key words/phrases: "food or meal or diet" and "program or information system". A total of 669 patents (539 for Korea and 130 for Japan) were finally selected and analyzed. Based on Porter's value chain theory, the patents were categorized into three dimensions related to "manufacturing/processing/distribution", "sales & marketing", and "consumer support". The results showed that in Korea, 41.7% of the total patents were related to sales & marketing followed by consumer support (37.3%) and manufacturing/processing/distribution (21.0%). In Japan, patents related to consumer support accounted for 56.2% followed by manufacturing/processing/distribution (32.3%), and sales & marketing (11.5%). In the area of manufacturing/processing/distribution, "food quality management system" in Korea, and "food manufacturing and processing management system" and "food safety control and hazard analysis system" in Japan tended to show a significantly higher proportion of patents registered (p<.05). Under sales & marketing, patents in the categories of "food purchase and delivery service system" in Korea and "restaurant information sharing system" in Japan tended to be more frequently registered (p<.05). Finally, in the area of consumer support, "kitchen facility and cooking device control system" in Korea and "menu and nutrition management system" in Japan tended to account for a significantly higher proportion of patents registered (p<.001). The results are expected to provide useful insights into the development of new patents and markets for food tech in the future.

Profit-keeping behaviors naturally occur in the market to satisfy consumers, and the logic behind it lies in the economies of scale. On the flip side, some commodities transacted in the market are not available or can not be easily acquired unless the demand is high enough. Under this proposition, some consumers rise and find their own solution to meet the services at a reasonable cost or at an adequate level. The commonly adopted way is to establish a cooperative, and it stirs purchasing power by pooling resources and further bargains price and service quality. As a consumer cooperative, housing cooperatives notably found in rural towns enable the elderly to continue independent living. This study is to take a closer look at residential life of the rural elderly in housing cooperatives. Utilizing in-depth focus group interviews with 40 residents in four housing cooperatives, this qualitative research draws main factors affecting the decision to move in, residential assessment, and strengths and weakness of living in a housing cooperative. The primary factor influencing the moving decision is to continue to independent living in a familiar community, and the bottom line is planning ahead. Frailty and bereavement are found to be the leading occasions for them to move. The participants are satisfied with the independent living arrangement, and particularly, cited such features as safety and security, elderly-friendly design, common spaces, freedom, social activities and efficient living. Also, it is stated that some cooperative natures such as control over the property and giving a voice on management render positive impacts on the satisfaction with communal living. In spite of all the benefits and strengths, participants face with a public notion that an independent living arrangement like a housing cooperative has never done before in rural towns, so that most people recognize it as part of dependent living arrangements like nursing home.

Although a number of studies have been conducted on the association between GSTM1 polymorphisms and lung cancer in China, this association remains elusive and controversial. To clarify the effects of GSTM1 polymorphisms on the risk of lung cancer, a meta-analysis was performed in the Chinese population. Related studies were identified from PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM) up to 5th April 2014. A total of 45 articles (47 studies) including 6,623 cases and 7,865 controls were involved in this meta-analysis. Overall, a significant association (OR = 1.45, 95%CI: 1.32-1.60) was found between the null GSTM1 and lung cancer risk when all studies in Chinese population pooled into the meta-analysis. In subgroup analyses stratified by quality score, geographic area and source of controls, the same results were observed under all the models. This meta-analysis showed that the null GSTM1 may be a potential biomarker for lung cancer risk in Chinese, but further studies with gene-gene and gene-environment interactions are required for definite conclusions.

음성의 특성은 지연에 매우 민감한 (delay-sensitive) 트래픽으로 시스템에서 손실에 민감한 (loss-sensitive) 다른 트래픽과 동일한 방식으로 서비스되어서는 두 트래픽 모두의 QoS (Quality of Service)를 만족시킬 수 없다. 효율적인 트래픽의 처리를 위해서는 시스템의 상태에 따라 손실에 민감한 트래픽에 영향을 적게 주면서 지연민감 트래픽의 성능도 만족하는 것이 바람직하다. 본 논문에서 도입한 동적우선권제어함수 (Dynamic Priority Control Function, DPCF)는 시스템의 상태에 따라 각 트래픽에 우선권을 동적으로 할당하여 서비스 스케줄링을 제어하는 함수f(·)로 기존의 우선권 제어방식을 더욱 일반화시킨 방식이다. 클래스 1의 손실민감 트래픽과 음성과 같은 클래스 2의 지연민감 트래픽을 수용하는 시스템에 TBPJ (Threshold-based Bernoulli Priority Jump) 방식의 DPCF을 적용하여 성능을 분석하였다. DPCF은 각 시스템에 대기하고 있는 트래픽의 양과 시스템의 가용 용량인 버퍼의 threshold에 따라 각 트래픽 클래스에 우선권을 동적으로 할당하여 서비스가 이루어지도록 한다. 성능분석을 통하여 TBPJ 제어방식이 기존의 우선권 제어 방식보다 성능 및 효율성에 있어서 우수함을 입증하였다. 즉 성능을 분석한 결과 손실민감 트래픽의 성능저하는 미미하고 지연민감 트래픽의 성능향상은 현저히 개선된 것을 확인하였다.

This case study aims to explore how RDA PLA model affects the agri-SMEs' empowerment. As an agri-business management renovation program from main workshop it was conducted on March to December 2011 with agri-SMEs and extension officials nationwide by RDA. Especially, as a packaged action learning process in the model used participatory action research. This study collected data with participants observation, interviews, situational analysis and systematic review of discourse in qualitative method. For the validity and identifying empirical results, this study used statistic analysis as a mixed method. Further including various pedagogic methods and business coaching skills, this model was conducted from workshop in RDA, in turn, on-farm business coaching as follow-up, CoPs' activities, and local ATCs extension services by each actors. The dynamic process and effects of each process led some change for farmers' innovative knowledge, skills, attitude, practice and aspiration on their farm business. RDA PLA model development based on the previous practices and research, which provided a configurated picture in the holistic action learning process. In statistic research, this study focused on 279 farmers as respondents who had participated in the program. It shows that their income and benefits increased from their renovative practices on farm business. Following the sampling group, it was surveyed by four indicators - products, customer, quality and cost. The level of contribution of education on economic impact 15% is quoted from previous paper. Even in some limitations of public sector, RDA PLA model actively suggests the paradigm shift of agricultural HRD and development of alternative extension-service system.

Purpose: The purpose of this study was to identify patient satisfaction about nursing care provided by Advanced Practice Nurses (APN) using the La Monica-Oberst Patient Satisfaction Scale (LOPSS). Methods: The investigation was conducted including 263 patients who experienced care provided by 41 APNs at a tertiary hospital in Korea. Patient satisfaction with nursing care was measured using 41-item LOPSS. We analyzed the data using descriptive statistics, independent t-test and one-way ANOVA. Results: Overall patient satisfaction with APN care was high. The LOPSS scores for APNs were 52.26 for good impression, 61.75 for interpersonal support, 81.32 for dissatisfaction and 195.93 for total score. "APNs talk down to me" was a reverse coding item which demonstrated the highest score for patient satisfaction. Among patients' characteristics, age and type of main caregiver were independent factors related to patients's satisfaction. Among APN's characteristics, work experience was significantly related to patients' satisfaction. Conclusion: This study identified patient satisfaction regarding nursing care provided by APNs. High patient satisfaction in APN services demonstrated APNs' contribution to quality improvement in health care services. It is recommended that various outcome research about APN service needs to be performed.

The commercial Korean native chickens (WR_CC) was developed by crossing a few native chicken breeds in Korea. In order to investigate the breed identification markers, SNPs from TYR gene and MC1R gene, which are associated with skin and feather colors respectively, were initially identified. In case of 3 identified SNPs in the TYR gene, yellow shank color was identified in Loss, Harvard, AA, RIR and CC, which have the fixed SNPs in most of the animals. On the other hand, SNP variations were observed in KNC_RB, C_B, WR_CC and HH_CC, which have the black, yellow and mixed color with black and yellow shank colors. Also, the investigation of 3 SNPs in the MC1R gene indicated that there were associations between shank and feather colors in RIR, SF, KNC_B, C_B and RIR. However, these results are not consistent among breeds. These SNP type inconsistencies within breeds suggested that the selection was performed based on the phenotypes, which is not include the genotype information. Thus, selection based on genetic information is required in the future.
