This experiment investigated the effects of feed additives of Sasa quelpaertensis Nakai (SQN) extract on Landrace pigs on economic traits such as the quality, physiological characteristics, and productivity. Sixteen pigs with an average age of 154 days were selected as experimental subjects. The experiment was conducted by dividing the group into eight pigs for the supplementation group, feeding with SQN extract, and another eight for the control group feeding without SQN extract. Water was fed ad libitum. On the 30th day, there was no significant difference between meat quality and productivity. However, the glucose and thyroxine were statistically lower with the supplementation group than with the control group (p<0.05). Also, the levels of creatinine difference between 1.18 ± 0.12 ㎎/㎗ with the supplementation group and 0.70 ± 0.06 ㎎/㎗ with the control group (p<0.05). However, all serum biochemistry values were within a normal range, with no health problems. The present study will help solve the problem of reducing the diversity of plant species in Halla Mountain by increasing the availability of the SQN as a pig feed additive.

This study surveyed Chinese elderly consumers to determine their purchasing behavior, importance, and satisfaction with HMR products in China. Three hundred and seventy people were surveyed: 184 males and 186 females aged 55 to 70 years. Two hundred and sixty-seven (72.25%) of the surveyed consumers had an average monthly income of 6,000 yuan or less, and 313 (84.9%) responded that they spend 3000 yuan or less on groceries per month. Three hundred and fortyeight (94.1%) showed a high interest in health management. Regarding the frequency of purchasing HMR products, most responded that they purchased HMR products more than once or twice a week, with a single purchase of 100 yuan or less for each purchase. The respondents preferred 2 or 3 serving packagings in a refrigerated form. For all forms of products, those made as in-house meals, outdoor meals, as a snack or night snack, for serving guests, for trips, camping, and on-thego products, the participants mostly responded that they frequently purchased the product. When purchasing HMR products, the importance of hygiene, convenience in purchase accessibility, the freshness of ingredients, and an indication of the nutritional content were considered as a high rank. After purchase, the satisfaction of SNS and mobile application advertisements and promotions, amount per serving, take out convenience, and new menu were considered low-rank. The IPA results showed that marking the origin of the ingredients and new menu are areas needing improvement. The study results may be used as base data for developing elderly friendly HMR products and establishing its marketing strategies.

The purpose of this study is to estimate potential yield (PY) for Korean west coast fisheries using the holistic production method (HPM). HPM involves the use of surplus production models to apply input data of catch and standardized fishing efforts. HPM compared the estimated parameters of the surplus production from four different models: the Fox model, CYP model, ASPIC model, and maximum entropy model. The PY estimates ranged from 174,232 metric tons (mt) using the CYP model to 238,088 mt using the maximum entropy model. The highest coefficient of determination (R2), the lowest root mean square error (RMSE), and the lowest Theil’s U statistic (U) for Korean west coast fisheries were obtained from the maximum entropy model. The maximum entropy model showed relatively better fits of data, indicating that the maximum entropy model is statistically more stable and accurate than other models. The estimate from the maximum entropy model is regarded as a more reasonable estimate of PY. The quality of input data should be improved for the future study of PY to obtain more reliable estimates.

본 연구는 짐 쉐리단의 영화 『아버지의 이름으로‏‎』를 중심으로 아일랜드 와 영국 간의 갈등관계와 영국의 의도된 조작으로 인해 아일랜드인이 어떻게 테러리 스트로 낙인찍혔는지에 대한 과정을 살펴본다. 쉐리단은 ‘길포드 4인’ 사건으로 알려 진 실화사건을 형상화 함으로써 영국정부가 아일랜드인을 테러리스트로 동일시하거나, 심지어 테러 사건과 무관한 평범한 아일랜드인까지 테러리스트로 조작한 불합리한 상 황을 전달한다. 달리 말해, 이 영화는 테러리스트로 누명을 쓴 ‘게리 콘론’의 이야기를 다룸으로써 영국이 아일랜드를 억압한 역사뿐만 아니라 테러리즘의 양가적 의미 역시 상기시키고 있다.

This paper tries to show the efficiency of water financing between central and local governments. From the year of 2017, the operation and maintenance costs for change water pipes has been provided by central government as block grants system(RDSA: Regional Development Special Account). Even though the water financing is responsible for local government, water drought and high production cost in poor area affects the quality of life nowadays. Then, fiscal transfer through block grant for water financing has been decided to invest regional SOC. The purpose of the paper sheds light on the function of the block grant for public provision by water financing. The firstly tried empirical results are based on the survey from local governments and ministry of environments. The point of the empirical analysis shows that the local governments does not have proper measurement for unexpected water leakage and termination until now. In a policy manner, the paper raises the issues about benefit principle for water users by the increase of tariffs. In order to do so, the paper investigates the relationship between the water provision and fiscal status of each local governments.

고준위 방사성폐기물로 분류되는 사용후핵연료를 현재 기술로 가장 안전한 격리 방법으로는 500 m 심도의 안정한 암반에 심지층 처분하는 방법으로, 가장 중요한 요건은 공학적방벽인 완충재의 온도가 100℃를 초과하지 않도록 시스템을 설계하 는 것이다. 국내의 경우 전체 전력 소요량의 약 30% 정도를 차지하고 있는 원자력발전으로 발생되는 사용후핵연료의 양은 지속적으로 증가하여 누적되고 있어, 이들을 처분하기 위한 소요면적도 증가하고 있다. 따라서, 본 연구에서는 처분면적을 감소시킴으로써 처분효율을 향상시키기 위한 목적으로 다양한 복층처분 개념을 도출하였다. 이를 바탕으로 중요한 처분시 스템 요건 만족여부를 확인하기 위하여 열해석을 수행하고 그 결과를 분석하여 처분시스템 열적 안정성을 평가하였다. 평 가결과, 기준시스템 위치인 500 m 심도로부터 상부 또는 하부로 75 m를 이격한 심도에 복층으로 처분시스템 구축이 가능 하였으며, 실제 부지특성자료에 따른 상세 분석이 요구된다. 본 연구결과는 사용후핵연료 관리정책 수립 및 실제 처분시스 템 설계에 활용될 것으로 사료된다.

본 연구에서는 직/편물 8종을 대상으로 이들 수직방향과 수평방향 수분이동특성 측정방법에 따른 소재들의 수분이동 특성을 분석하였다. 또한, 8종의 시편의 MMT에 의한 건조특성을 수직 건조 측정 결과와 비교하여 논의하였다. 수평 수분이동 방법인 MMT 시험 결과는 수직법인 바이렉 방법의 결과와 유사한 거동을 나타내었다. 대나무, 린넨 및 면/나일론 복합 소재는 드롭법의 흡수시간은 짧았으며, 표면의 낮은 접촉각 및 직물의 높은 다공성에 기인한 것으로 판단되며, 친수성 스테이플 섬유의 구조와 상관이 있을 것으로 보인다. MMT에 의한 건조특성은 니트 및 대나무 직물의 최대 흡수반경이 가장 우수했으며, 수식 건조법에 비해 차이를 나타내었다. MMT 방법의 건조속도는 직물의 두께와 포화수분 흡수율과 높은 상관성을 가졌으며, 회귀계수는 각각 0.9와 0.88이었다. 이는 직물의 두께가 얇을수록 위킹 및 건조특성이 우수하며, 기능성 소재기획시 착용 내구성을 판단하는데 중요함을 의미한다. 또한 상이한 섬유소재, 실 및 구조의 소재에 대한 수분이동특성(위킹, 건조)는 측정 방법에 따라 다른 결과를 나타내었다.

Yield-per-recruit (YPR) analysis is used to provide management guidance for the efficient use of a fish cohort. However, the individual fish price per unit weight of small yellow croaker (Larimichthys polyactis) or hairtail (Trichiurus lepturus) increases dramatically by size in Korea. Therefore, age-based production value-per-recruit (PPR) analysis has recently been developed (Zhang et al., 2014). Since age determination requires a substantial amount of money and time and it is even impossible for some fish species, it is difficult to obtain age information to apply the age-based PPR model. Thus, we attempted to develop an alternative method, which uses length data rather than age information, called the length-based PPR analysis. The results revealed that length-based PPR analysis was much more conservative for stock management than the YPR analysis. Furthermore, the PPR analysis was more economically beneficial than the YPR analysis, which can prevent the fish stock from the economic overfishing. In conclusion, the length-based PPR analysis could be a proper approach for stock assessment in the case that the individual fish price per unit weight increases dramatically by size, and this analysis is useful to obtain vital management parameters under data-deficient situation when traditional stock assessment methods are not applicable.
