Nano-sized $TiO_2$-60 wt% SrO composite powders were synthesized by a sol-gel method using titanium isopropoxide and $Sr(OH)_2\;{\cdot}\;8H_2O$ as precursors. 3, -5, -7 wt%Ag spot-coated $TiO_2$-60 wt% SrO composite powders were synthesized by a Ag electroless deposition method using $TiO_2$-60 wt% SrO composite powders calcined at $1050^{\circ}C$, which mainly exhibited the $SrTiO_3$phase. However, a small number of rutile $TiO_2$, $Sr_2TiO_4$ and $SrO_2$ phases were also detected. In the Ag spot-coated powders synthesized by electroless deposition, nano-sized particles about 5-25 nm in diameter adhered to the $TiO_2$-60 wt% SrO composite powders. The photocatalytic activity of Ag spot-coated $TiO_2$-SrO and $TiO_2$-SrO composite powders for degradation of phenol showed that all of $TiO_2$-SrO composite powders were highly active under UV light irradiation. 7 wt%Ag spot-coated $TiO_2$-60wt.%SrO composite powders had a relatively higher photocatalytic activity than did $TiO_2$-SrO composite powders under visible light.

Nanofiber is a broad phrase generally referring to a fiber with diameter less than 1 micron. Various polymers have been successfully electrospun into nanofibers in recent years. These nanofibers, due to their high surface area and porosity, have a great potential for use as filter medium, adsorption layers in protective clothing, etc. Nanofiber filters will enable new levels of filtration performance in the field of air filtration. In particular, nanofibers provide marked increases in filtration efficiency at relatively small pressure drop in permeability. Therefore, nanofiber filters could be substituted for conventional filter market due to the easy application of process and the possibility of coating to micron-sized non-woven sheets. This review is discussed on the trend of researche and development related to nanofiber filter including future marketability.

Purpose : This study was conducted to determine the effect of intervention using a smartphone application on abdominal muscle thickness and maximum voluntary ventilation when conducting pelvic floor muscle exercise (PFME). Methods : This study was performed on 14 subjects. They were divided into two groups; PFME using smartphone application (n=7), common PFME (n=7). Both of group executed the exercise 5 times a week for 1 weeks. Abdominal muscle thickness was measured using ultrasound. Maximum voluntary ventilation was measured using a spirometer. The smartphone application used the paid version of Kegel trainer. This material was analyzed by the paired t-test to compare differences on each group and the independent t-test to compare between the two groups. Results : The PFME group using the smartphone application showed a significant increase in the transverse abdominis and internal oblique muscles (p<.05). The common PFME group showed a significant increase in the internal oblique muscle (p<.05). There was no significant difference in variation of the muscle thickness between the two groups (p>.05). The PFME group using the smartphone application showed a significant increase in the maximal voluntary ventilation (p<.05). There was no significant difference in variation of the maximal voluntary ventilation between the two groups (p>.05). Conclusion : As a results of this study, PFME using a smartphone application seems to induce voluntary participation of subjects and maintain continuity against time constraints. As a result, it is thought that using a smartphone application when performing PFME is efficient and convenient in terms of research method. However, this study is difficult to generalize due to the small number of subjects and short intervention period. Therefore, additional research should be conducted by modifying and supplementing these limitations.

Purpose: The study aims to examine the effects of the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy on pain, range of motion (ROM), and shoulder dysfunction in breast cancer patients. Methods: In total, 30 breast cancer patients were recruited and randomized to group I (n = 10), group II (n = 10), and group III (n = 10). Pain was measured using a visual analogue scale, ROM was measured using a goniometer, and shoulder dysfunction was measured using a shoulder pain and disability index. Group I practiced the proprioceptive neuromuscular facilitation pattern exercise and underwent scrambler therapy, group II underwent scrambler therapy only, and group III practiced the proprioceptive neuromuscular facilitation pattern exercise only. Results: A within-groups comparison showed that all groups demonstrated significant differences in pain, ROM, and shoulder dysfunction after the experiment (p<0.05). Further, according to a comparison of the three groups, group I showed a more significant difference in effectiveness than groups II and III in terms of pain, ROM, and shoulder dysfunction before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy are effective in treating pain, ROM issues, and shoulder dysfunction in breast cancer patients.

Accelerated technological advances and the convergence of information and communication technologies have led to changes of career concepts from one of lifetime employment to that of lifetime career. Given the importance of continuous career development for workers these days, systematic supports for workers' career development at the national level is necessary. Accordingly, a conceptual model of career competency mobility map (CCMM) has been proposed to support the development of workers' career competencies. The purpose of this study is to identify key issues that we should consider for real implementation by applying to each stage of the CCMM conceptual model as a case study. Based on the procedure presented in the conceptual model, the research process which includes collecting user information, conducting self-diagnosis of NCS-based job competencies, deriving necessary training competency, offering the guidance of training programs and job information were conducted. The results of the case study showed our participants' scores of competencies required further development and ranged from 1.83 to 4.52. Sequentially, a personalized information profile was offered for competency development, including training, certificates, and job information. Participants stated that the diagnosis results and profiles were meaningful and helped to explore further career development. Based on the results, implications are suggested.

To produce high quality watermelon, three tetraploid watermelon breeding lines (‘SA03-1’, ‘SA06-1’ and ‘SB01-1’) were developed by treatment with different chromosome doubling reagents. To identify the optimal tetraploid inductive conditions, the three watermelon breeding lines were selected by counting the number of doubled chloroplasts in guard cells. Tetraploid induction rates differed depending on the genotypes and treatment with doubling reagents. However, the highest induction rate occurred with 1.0% colchicine (82.2%). These putative tetraploid lines were re-confirmed for ploidy using flow cytometric analysis and chromosome counting. The internode length of the tetraploid breeding lines was different when the leaf size was larger in all three tetraploid lines compared to their diploids. The fruit weight of the tetraploid fruits for ‘SA03-1’ and ‘SB01-1’ was lower than for their diploid, and the rind thickness and total sugar content (°Brix) of tetraploid SB01-1 were significantly different from those of its diploid. Tetraploid lines were sterile, yielded a lower number of seeds per fruit for ‘SA03-1’ (21), ‘SA06-1’ (62), and ‘SB01-1’ (34.7), and the seeds were larger and thicker than those of their diploids. These tetraploid breeding results will be useful for breeding new seedless watermelon cultivars.

본 연구의 목적은 정부출연연구소에서 연구개발된 기술이 민간부문에서 충분히 활용되지 못하고 있다는 문제의식으로부터 출발하여, 원천, 핵심기술의 확보가 국가경쟁력을 좌우하는 첨단기술경제시대에 막대한 국가자금으로 연구개발된 우수한 기술의 사장을 방지하고 궁극적으로 국가경제발전을 위한 전략적 기술이전 촉진 방안을 모색하는 것이다. 현재 국무총리산하 기초, 산업, 공공기술 연구회로 분류 조직되어 있는 3개 연구회 총 1개 정부출연연구소의 지난 10년간(1992-2001)의 연구예산규모, 보유특허수, 기술이전건수, 기술징수액, 기술실시계약서를 방문 조사하고 각 연구소의 기술이전전담조직의 실무자를 대상으로 설문 조사하여 설문 및 통계분석 결과를 토대로 기술이전관련 문제점 파악 및 기술이전 촉진을 위한 전략적 개선방안을 모색해 보았다. 먼저 기술이전 현황을 살펴보면 기술이전건수는 보유특허수의 3%미만, 기술료 징수액은 연구예산규모의 2%미만으로 기술이전 및 기술상업화율이 상당히 저조하다. 설문 및 통계분석 결과로부터 TLO 조직의 비효율적인 운영, 비전문성, 열악한 운영인력, 적극적인 기술이전을 위한 동기부족, 정부의 제도적인 지원부족, 기술실시계약서 조항들의 경직성 등을 기술이전 관련 문제점으로 도출해 낼 수 있었다. 이러한 문제점을 극복하고 기술이전 촉진을 위한 개선방안으로는 첫째, TLO 조직을 전략으로 개편해야 한다. 즉 기술이전 전담인력을 변리사, 전문 협상가, 연구원 둥 전문가들로 구성하여 지적재산권 관리, 기술평가, 시장조사, 기술마케팅, 사후관리 등을 효율적으로 수행해야 한다. 둘째, 정부의 정책적인 지원이 필요하다. 기술이전 전담조직에 대한 인센티브 시스템 기술이전을 위한 특별예산 편성 등을 정책적, 제도적으로 도입하는 등의 적극적인 지원이 요구된다. 셋째, 기술실시계약서 조항들을 기술실시자의 실질적인 기술 상업화에 도움이 되고 기술 유출 및 기술사장화를 방지하는 방향으로 개선하여야 한다. 특히, 전용실시권과 실시대가, 기술실시 및 지적재산권 관리와 관련된 제반 비용의 부담비율 등을 보다 유연하게 개선하여야 한다. 본 연구는 정부출연연구소에서 민간부문으로의 기술이전만을 고려하여 기술이전의 중요한 요소인 민간부문에 대한 고려가 전혀 없다. 따라서 보다 실질적이고 체계적인 결과를 도출하기 위해 민간부문을 고려한 연구가 진행되어야 한다고 생각한다.

The purpose of this study is propose performance indicators analysis and development plans for K University professional graduate school for the training of human resource professionals. Specifically, the main research includes the derivation of performance indicators for K University's professional graduate school, PR plan, academic establishment plan, name change, vision proposal, and curriculum improvement plan for each major. To this end, a survey was conducted on a total of 132 current and former students of K University's professional graduate school. FGI was also conducted with 29 participants. The results of the research are as follows. In the case of key performance indicators, 15 indicators were proposed, taking into account previous research, the characteristics of professional graduate school, surveys, and FGI surveys. Promotion should be continuous, not one-time, and the advantages and benefits of the graduate school should be actively informed to target customers. The proposed name of the professional association is the Korean Association for Employment and Vocational Competency Development. It was found that operating as a convergence society and focusing on convergence research were appropriate. The names of K University's professional graduate school were HR (Human Resources), HRD, and employment and vocational competency development graduate school. As for the vision, it was suggested that a balance between identity and differentiation is needed to flexibly respond to new changes while maintaining existing strengths. As for the proposed improvement of the curriculum by major, it is proposed to reform in a stepwise and gradual manner while maintaining the existing framework to some extent rather than being radical.
