An accurate mass and isotope ratio were determined using a gas chromatography/time of flight mass spectrometer in CI positive mode for the identification of unknown metabolites. High mass tune was used to improve the ion intensity of $[M+H]^+$. Chromatographic resolution and dynamic range enhancement were performed to obtain more reliable accurate masses and correct isotope abundance ratios. Average absolute errors of mass and isotope ratios for 24 reference metabolite -TMS (trimethylsilyl) derivatives were 6.8 ppm, 1.5% of (M+1/M ratio) and 1.7% of (M+2/M ratio), respectively. The correct formulas of twenty one compound were retrieved within top-2 hit from the heuristic algorithm for elemental composition using each accurate mass and isotope abundance ratio.

This research examines marriage migrant women's interpreting and translation work as an ethnic labor, analyzing its creation and work experiences. Major findings about ethnic labor in the research are as follows: First, Korean gendered and discriminatory- exclusive immigration policy enables the creation of interpreting and translation job to marriage migrant women. While the policy limits settlement and employment fields of male immigrant workers, marriage migration women are allowed to settle and find any job. Second, job security and wage of marriage migrant women's interpreting and translation work are still low, although the job is considered a relatively decent one in foreign immigrant labor market. Finally, they experience conflicts between role as neutral interpreters and identity as migrant women, facing native Koreans' distrust and discrimination against them. In conclusion, this study suggests some issues on marriage migrant women's empowerment and their labor market prospect in terms of the sustainability of this job.

Topophilia refers to emotional bonding such as attachment to or nostalgia for one's home town, which is remembered or imagined as a beautiful and happy paradise experienced in youth. The time spent in one's home town may have been short, but the associated memories of it are strong and enduring. These can later act as a strong motivator to learn if the correlated emotions are positive. According to archival research conducted on Jooyoung Chung's life, his home town and the things found therein, such as cows, were the principal objects of his topophilia, and later became the driving forces behind his success story. The same applies to Dvorak. Dvorak sublimated his nostalgia for his home town by composing a piece of music on hearing the sound of a train. We can discover diverse rhythms in nature such as sunrises and sunsets, the changing seasons, and even our heart beat. If a melody is added to the rhythm, it transforms into art. And if we seek harmony and principles, it becomes science. In this study, Jeonbuk's nature, places, food, and arts, as represented in its educational resources, are analysed for their ability to give rise to topophilia. To gain some experience of this feeling we recommend that you visit the Jeonju Hanok Village, the value of Gochujang, reverse icespike on Mai Mountain or enjoy the works of the painter Book Choi.

영국에서는 농촌문제의 심각성과 범정부적 대책 마련에 대한 부처간 인식 공유가 증가함에 따라 2000년 "농촌백서"에 '농촌서비스 표준화(Rural Services Standard, RSS)'를 제정하였다. RSS는 농촌 주민의 삶의 질 제고와 복지 서비스 향상을 위해 달성할 주요 서비스의 National Minimum을 의미한다. 매년 RSS 운용에 대한 지속적인 모니터링을 통하여 내용을 매년 업데이트 하고 있다. 교육 및 아동서비스, 광대역 통신, 사회적 돌봄, 우체국 서비스, 보건, 인터넷 접속, 긴급 서비스, 교통의 8개분야 13개 서비스 기준을 설정 제시하고 있다. 우리의 경우도 농촌 주민의 삶의 질 향상을 위한 범정부적 투자가 이루어져 왔지만 농촌지역의 사회서비스 기준을 도시와 비교해 보면 아직도 부족한 부분이 많이 있다. 농촌 인구가 감소되고 있는 상황에서 지속적인 하드웨어 중심적 투자에 대한 의문제기와 함께 농촌 주민들이 최소한의 공적 서비스를 활용할 수 있는 기반이 되어야한다는 의견이 대립되고 있는 가운데 그 해결책을 찾기 위하여 '농촌 서비스 기준'을 설정하자는 논의가 추진되고 있다. 이에 본 연구에서는 인구 5만 이상 군지역에 속하는 경상북도 울진군 기성면 척산리를 중심으로 농촌 정주지원 서비스 요구사항을 분석하였다. 척산리에는 총가구 187호 363명이 거주하고 있으며 지난 3년간 인구 이동이 전혀 없었다. 주민들의 연령대는 50~60대가 가장 많으며 척산 3리가 가장 고령화 되어 있는 것으로 나타났다. 교통 환경은 좋은 편이었는데 기성공용버스 정류장에 10곳 이상의 차편이 있고 7번 국도가 있어 타 지역으로 이동도 용이하였다. 마을에 보건/의료를 담당하는 곳은 보건진료소뿐이었으며 잦은 외근과 구급약 부족 등으로 불편을 호소하고 있었다. 응급상황 발생시 수송 가능한 응급체계는 갖춰져 있지 않았고 노인들이 가장 많이 이용하는 물리 치료실은 일주일에 3번 개방하기에 불편하다고 하였다. 3층 건물의 복지회관이 있으나 장날(5일장; 1일, 5일)만 개방되어 이용에 한계가 있었고 마을주민을 위해 운영되는 프로그램은 없었다. 논농사 중심의 경제생활이었고, 부녀회와 청년회 등은 면단위 또는 행정리로 묶어서 운영하고 있었다. 주민들은 울진군 면소재지 중 척산리에만 약국이 없어 불편한 사항이 많기에 약국, 물리치료실의 상시 개방을 필요로 하였으며 장날을 이용한 노인대상 영화상영, 강연회 등 다양한 문화프로그램 운영을 희망하였다.

Of 1,100 yeast strains which were isolated from various Korean fermented foods, screened for phosphate solubilization, five strains showed the ability to solubilize tricalcium phosphate. The 26S rDNA domain D1-D2 sequence analysis revealed the identification of strain Y393 and Y524 as Pichia anomala (99.8 and 100% identity, respectively), Y669 as Pichia farinosa (100% identity), Y901 as Candida versatilis (100% identity), and Y1101 as Pichia subpelliculosa (100% identity). All the phosphate solubilizing strains showed mesophilic characteristics. The temperature range for growth of 4 strains was $20{\sim}35^{\circ}C$ and P. farinosa Y669 was able to grow up to $45^{\circ}C$. The strain C. versatilis Y907 was able to grow at pH range of 5.0~6.0 and showed halophilic characteristics with tolerance to 15% of NaCl concentration. The Phosphate solubilizing yeast strains were survived well in bed soil for 8 weeks which were maintained densities of $10^7{\sim}10^8$ cfu/g. The highest phosphate solubilizing activity was observed in P. subpelliculosa Y1101. It solubilized 697.2 ug/mL of phosphorus from tricalcium phosphate with decrease in pH from 6.8 to 4.37 after 11 days of inoculation.

The purpose of this study is to analyze the influence of the selective migration of young age group and the stage migration which has proceeded through generations, on the transition of fertility and the population growth in the rural and urban in the case of Jeollabuk-do. For this, we use O-D matrix of 20-34 age group, the distribution of that group and women of child bearing age, and vital statistics in 1970-2010. The major findings of this study are as follows. First, the outflows from their birth place are common and dominant features of 20-34 age group in each time. Second, there is the stage migration which preceding generation moved from the rural areas to the cities in Jeollabuk-do and following generation has moved from the cities to Seoul metropolitan area. Third the selective outflow migration of young age group has leaded to reduction of the childbearing population, declining birthrate, aging and natural population decline. Due to the stage migration, these depopulation processes occurred in rural area in the past, and currently it expands to the cities with about 15 years time gap. In fact, there have been the natural population decrease which annual number of deaths exceed that of births from the late 1980s in the most rural areas and in the early 2000s, such a phenomenon has been confirmed also in urban areas. Therefore, this study concludes that the stage migration through generations is one of the crucial factor to the population growth in local cities and also brings out the step-wise population decrease in settlement hierarchies.

The purpose of this study is to attempt to interpret golf courses as event-generating spaces with consideration given to the time factor. Through a golf game, a variety of events such as the tee shot, second shot, putt, and hole out are generated. These events have been connected to a series of events after hole out such as birdie, par, bogey and so on. The series of events do not always occur in the same way. They reveal unexpected changes over time. These unexpected changes cause changes in the spatial characteristics and offer unforgettable memories for golfers. Gilles Deleuze mentioned the spatial characteristics as striated space and smooth space. Striated space can be defined as sedentary space. It is distant vision-optical space that has dimensional, metric and centered characteristics, whereas smooth space is defined as nomadic, close vision-haptic space that has directional and acentered characteristics. This study focused on the analysis of spatial characteristics according to striated space and smooth space. Golf courses generally show the characteristics of striated space before beginning the game. As soon as the game begins, however, the golf courses are converted into an event-generating space. The characteristics of striated space are transformed into smooth space, a nomadic space that amplifies the dynamic, changeable, de-scaled and non-metric system. Through the whole game, this transformation is dramatically repeated. On the other hand, the golfer, the subject of the game, senses the phenomenological experience in the process of orientation, center, definition, and domestication.

We examined the effect of delayed and immediate rewards on short- and long-term memory performance depending on the level of stress. It has been demonstrated that delaying feedback during memory tasks could lead to better retention than presenting it immediately (a.k.a., feedback delay benefit or delay-retention effect). In this study, we manipulated stress level(high-stress or low-stress), reward-timing(delayed or immediate reward), reward-existence(500 or 0 won) and retrieval-timing(delayed or immediate memory test). On the high-stress learning condition, one week later, the number of correct answers with delayed-rewards were significantly more than that of delayed-no-rewards but there was not any difference between immediate-rewards and immediate-no-rewards. On the other hand, in the high-stressful immediate memory test, immediate-rewards only had a positive effect on memory performance. The results indicated that delayed rewards improved long-term memory performance by promoting memory consolidation and the sensitivity to rewards was higher under the high-stress condition.

The industrial development of Goryeong County was started by the operation of the Ssangrym Agro￢industrial complex in the 1980s. As of 2m3, there are 6 industrial complexes in Goryeong County which account for 80 percent of total employment and 67 percent of total production outPuts in local manufacturing. The local manufacturing industries grew steadily before the 1997 financial crisis which resulted in industrial decline and have shown again a growing tendency since 2000. In this period of growth, manufacturing outPuts are increased and the industrial structure are improved, while employment and value added are in stagnation. The major industrial agglomerations are based in Gaejin-Myun, Dasan-Myun and Ssangrym-Myun, all of which are those in which the agro-industrial complex is operated. More than half of local manufacturing finns are those which came to move in from other regions, looking for cheap labour forces, agglomeration of the related finns and the easy accessibility to transport and communication. However, such local advantages are increasingly losing due to the shortage of labour forces and the lack of industrial networks. Some policy agendas can be suggested as follows. First of all, industrial policy should attempt links with the building-up of the Daegu Technopolis and the up-grading of the local industrial structure towards the knowledge-based industries. Secondly, the local government should make efforts to establish the innovation supporting system for local firms and the industrial and residential basis.
