Purpose: The purpose of this present study was to develop and evaluate the psychometric properties of a needs scale for patients with cancer undergoing follow-up care (NS-C). Methods: A preliminary NS-C of 48 was derived from literature reviews and in-depth interviews with patients with cancer. Content validation of the items was established by oncology physicians and nurses. Each item was scored on a five-point Likert scale. The preliminary NS-C and Eastern Cooperative Oncology Group (ECOG) performance status questionnaires were administered to 873 patients with cancer recruited from three university hospitals. The data were analyzed using factor analysis, multidimensional scaling analysis, ANOVA, Pearson correlation coefficients, and Cronbach's alpha. Results: From the factor analysis, 25 significant items in six subscales were derived. The subscales were named physical symptoms, diet and exercise, support, relationship with health professionals, treatment/prognosis, and keeping mind under control. The NS-C also established item convergent and discriminant validity, and known-groups validity. Cronbach's alpha of the subscales ranged from .90 to .92. Conclusion: This study suggests that the NS-C is an easy, reliable and valid instrument to measure the needs of patients with cancer. Health professionals may use the NS-C for patients with cancer both in practice and research.

During the past 100 years, Korean fisheries management policies have enforced the license system, it is the most typical regulation system in Korean fisheries. Even now, it has caused resource management failure, it has also invited economic inefficiency and inequity. Accordingly, the Korean government has recently introduced the self-regulatory management system for fishermen with the TAC system. These systems are one of the most market-oriented regulation systems in fisheries management systems. It is defined as regulatory policy tools other than regulations with command and control approach. It is also called “alternatives” which is composed of regulatory alternatives and non-regulatory alternatives. The self-regulatory management system and the ITQ system are cooperative-based co-management between government and fishermen as an alternative management strategy ; it is gaining the increasing attention to improve the effectiveness of fisheries management in Korea. It is expected not only to positively improve function in fisheries regulation, but also to decrease inefficiency in fisheries policies. However, these systems have many problems. The monopolization of rent is one of the typical examples. As solutions for the problem in the aspect of fishery management, fisheries policy is need of approach to industrial organization. For instance, Contestable market theory is one of the good theoretical background, it mean that market is able to free entry and free exit. Thus, fisheries management carry out policies such as revitalization of the used market of capital goods in fisheries, organize of the self-regulatory management group. Conclusively, as the exploiters and managers, fishers and the government should put emphasis on improving economic efficiency so that fishery would grow as an industry that contributes to the increase of social welfare, and the change to that direction will be the only way for our fisheries to preserve its importance.

본 논문에서는 CDD-DF-Relay 기법을 MC-CDMA 시스템에 대해 제안하고 제안된 기법의 성능을 다중경로 레일리 페이딩 채널에서 검증한다. 일반적인 DF-Relay 기법에서는 모든 Relay들이 직교 채널들로 신호를 전송하여야 하기 때문에 그 장점 즉, 다이버시티 이득은 주파수 효율의 저하로부터 얻어진다고 할 수 있다. 따라서 이러한 주파수 효율 저하의 문제점을 해결하기 위하여 본 논문에서는 CDD 기법을 각 Relay 노드에 적용하여 모든 Relay가 하나의 채널만을 사용하도록 한다. 이는 Destination에서 바라본 하나의 R-D 링크 채널의 Delay Spread가 길어지는 효과를 갖는다. 즉 Relay 개수의 증가에 따라 다중 경로수가 증가됨을 의미하고, 이는 MC-CDMA 시스템에서 주파수 다이버시티 이득으로 해설될 수 있다. 모의실험에서는 일반적인 DF-Relay 기법과 제안된 CDD-DF-Relay 기법의 성능을 비교 분석한다. 이를 통해 제안된 기법이 주파수 효율의 저하없이 협력 다이버시디 이득을 획득할 수 있음을 확인하였다.

In a pilot-scale dyeing wastewater treatment using two-type fluidizing media, each thickness of biofilm was 15 and 30 ${\mu}m$, respectively. The numbers of protozoa inhabited in small-size (PEMT A) and big-size (PEMT B) media were $7.5{\times}10^4$ and $1.25{\times}10^5$ cells/ml, respectively, and dominant species were Entosiphon sulcatus var sulcatus in PEMT A and Chlamydomonas reinhardtii in PEMT B, respectively. Flask experiments using the two media revealed that the percentages of color removal were 25.8% in PEMT A and 27.1% in PEMT B after 72-h cultivation, indicating the necessity of bioaugmentation. Experiments for bioaugmentation effect on color removal were carried out in the pilot-scale treatment for 75 d by three-step operation under the control of wastewater loading rate and microbial input rate. Dye degradation occurred mainly in the second reaction tank, and the attachment of augmented dye-degrading microorganisms to media took at least 35 d. Final value of chromaticity in effluent was 227, meeting the required standard. Therefore bioaugmentation onto media was good for color treatment. In summary, thickness of biofilm formed on the media depended upon the size of media, resulting in different ecosystem inside the media. Hence, this affected microbial community and color treatment further. Accordingly, the reduction of operation cost is expected by efficient color-treatment process using bioaugmented media.

Purpose: The aim of this study was to determine if Pilates gymball exercise can change the electroencephalogram and cognitive function of mentally disabled people. Methods: Twenty-one mentally disabled people were enrolled in this study. They were assigned randomly to one of two groups: Pilates gymball exercise group (PGEG, n=11), and control group (CG, n=10). The subjects in the PGEG group performed the exercises for 50 minutes a day, three days per week for 6 weeks. The PGEG program consisted of warm up (10 minutes), main workout (30 minutes), and cool down (10 minutes). The main workout consisted of 10 exercise programs. The electroencephalogram (EEG) of Fp1, Fp2, F3, F4, C3, C4, O1, and O2 were measured using an PolyG-I system. The cognitive function was evaluated using a mini-mental state examination (MMSE). The measurements were performed before exercise, and 6 weeks after exercise. Covariance analysis (ANCOVA) was performed to determine the difference between the two groups Results: A significant difference in Fp1, Fp2, and F3 on the relative alpha power was observed between the PGEG and CG groups (p<0.05). A significant difference in Fp1 on the relative beta power was observed between the PGEG and CG groups (p<0.05). No significant difference in the MMSE score was observed between the PGEG and CG groups. Conclusion: Pilates gymball exercise did positively change the EEG in the frontal lobe. On the other hand, the effect related to cognitive was limited. Pilates gymball exercise appears to be more effective in facilitating brain stimulation related to cognition.

Lysobacter antibioticus HS124 isolated from pepper rhizosphere soil produced catechol type siderophore. Purified siderophore by Diaion HP-20 and silica gel column chromatography showed several hydroxyl functional groups adjacent to benzene rings by analysis of $^1H$ NMR spectroscopy. The strain HS124 showed different activities to suppress Phytophthora capsici with different concentrations of exogenous Fe (III) in minimal medium where antifungal activity with $100{\mu}M$ Fe (III) was approximately 1.5 times higher than in absence of Fe (III). Bacterial population in this Fe (III)-amended medium was also highest with $8.9{\times}10^8\;CFU\;ml^{-1}$ which also corresponded to the strongest siderophore activity. When grown in rich medium (minimal medium with N, $P_2O_5K_2O$ and glucose), HS124 exhibited approximately 2 times stronger antifungal activity compared to minimal medium. In pot trials, treatments of bacterial culture grown in rich medium with (C1) or without (C2) $100{\mu}M$ Fe (III) exhibited a high protection of pepper plants from disease, compared to medium only with (M1) or without (M2) $100{\mu}M$ Fe (III). Especially, treatment C1 showed the best disease control effect of about 70 %. Thus, the strain HS124 should be recommended as a potential biocontrol agent against P. capsici in pepper.

Purpose: The purpose of this study was to identify the influence of nursing organization culture on resilience of new nurses. Methods: Participants were 1,033 new nurses with careers of less than 12 months and who were from 43 general hospitals located in Seoul, Incheon, other metropolitan cities and provinces in Korea. The data were analyzed using t-test, ANOVA, Pearson correlation coefficient and multiple regression with SPSS/WIN 24.0 program. Results: Relation-oriented culture was scored highest for perception of organizational culture by new nurses (3.35), followed by hierarchy-oriented culture (3.19), innovation-oriented culture (3.12), and task-oriented culture (2.73). The score for resilience of the new nurses was 3.49, and the first subcategories were interpersonal relationship ability 3.66, self-positivity 3.45, and self-control ability 3.36. Relation-oriented culture (${\beta}=.30$, p<.001) was the most significant factor influencing resilience of new nurses, followed by innovation-oriented culture (${\beta}=.14$, p=.001), hierarchy-oriented culture (${\beta}=.12$, p<.001), task-oriented culture (${\beta}=-.10$, p=.003) in that order ($R^2(adj. R^2)=.16$, F=47.04, p<.001). Conclusion: Findings show that for improved resilience in new nurses it is necessary to develop relation-oriented culture to provide a cooperative work environment(friendly interpersonal relation and dialogue) for new nurses and to encourage involvement of these members in the hospital culture.

우리나라의 군 간부들은 현역복무 후 계급정년으로 인해 본인의 의사와 관계없이 조기에 이직할 수밖에 없는 실정으로 최근 중 장기 복무자의 5년간 평균 취업률이 55%수준에 머무르고 있는 현실에 비추어 그 대책이 절실한 상태이다. 지난 박근혜 정부에서 제대군인 일자리 5만개 창출을 국정과제로 선정하여 추진하였으나 그 성과는 크지 않았다. 따라서 이제는 제대군인들의 대규모 일자리 창출을 위해 정부차원의 노력과 학문적 차원의 취업기회 확대 등 기존의 방식을 과감하게 탈피하여야 하며 제대군인들 스스로가 자립하여 조직을 만드는 방안 등을 적극적으로 검토할 필요성이 대두된 것이다. 그러한 이유로 본 연구에서는 제대군인들의 일자리 창출을 위해 제대군인들 스스로 사회적 협동조합을 설립하여 현역부대에서 이루어지고 있는 부대개방행사, 병영체험 등 비전투업무 부담을 경감시켜 주고 먹거리 사업, 경호 경비인력 양성 및 인력제공 사업, 특기병 양성학원 운영 사업, 한강 수중청소 사업, 돌봄 사업, 택배 사업 등을 통해 일자리를 창출하는 방안을 제시한다.
