Implementing a rural revitalization strategy will help spread traditional culture and promote the sustainable development of traditional handicrafts. Batik is a traditional handicraft made by residents in China's minority areas in their daily lives. This study was conducted because of a lack of objective methods for evaluating related project plans. This study was conducted to develop an index for the sustainable development of functional traditional batik production. This study had three major parts. The first part was a literature review that investigated sustainable and traditional batik dyeing and a field investigation carried out in Shitou Village, Danzhai County and Danzhai Paimo Village, Anshun, Guizhou to identify the factors that influence traditional batik production. The second part identified the factors identified in previous research that affect sustainable, traditional batik production and the projects executed to do the same. The third part was a survey conducted using the Delphi method. The results were analyzed, producing 10 influencing and 23 detailed factors that affect traditional batik production. Future research in this area should draw on various disciplines, investigate the direction in which traditional batik production is developing, and determine how to promote the sustainable development of other traditional handicrafts.

With the development of advanced technology, automation of agricultural work is spreading. In association with the 4th industrial revolution-based technology, research on field smart farm technology is being actively conducted. A state-of-the-art unmanned automated agricultural production demonstration complex was established in Naju-si, Jeollanam-do. For the operation of the demonstration area platform, it is necessary to build a sophisticated, advanced, and intelligent field smart farming model. For the operation of the unmanned automated agricultural production demonstration area platform, we are building data on the growth of soybean for smart cultivated crops and conducting research to determine the optimal time for agricultural work. In order to operate an unmanned automation platform, data is collected to discover digital factors for water management immediately after planting, water management during the growing season, and determination of harvest time. A subsurface drip irrigation system was established for smart water management. Irrigation was carried out when the soil moisture was less than 20%. For effective water management, soil moisture was measured at the surface, 15cm, and 30cm depth. Vegetation indices were collected using drones to find key factors in soybean production prediction. In addition, major growth characteristics such as stem length, number of branches, number of nodes on the main stem, leaf area index, and dry weight were investigated. By discovering digital factors for effective decision-making through data construction, it is expected to greatly enhance the efficiency of the operation of the unmanned automated agricultural production demonstration area.

Hanwoo, Korean cattle, is traditionally an important livestock to farmers and also important meat to consumers. Recently, to make more efficient production system and provide cheaper and high-quality hanwoo meat, the scale-up via brand is emphasized. However, the price of hanwoo is getting higher and the price increase is considered to occur due to marketing margins in the distribution process. In this study, factors affecting the hanwoo marketing margin are analyzed using 2004-2009 monthly data. In the Cochrane-Orcutt estimation of marketing margin, hanwoo production, other domestic production and import, income, output index, market share of major retailers, and market share of hanwoo brands shows statistical significance in the result. The results shows basic factors of the marketing margins to hanwoo and gives some implications to the management system of hanwoo brand like a sophisticated market segmentation and a differentiated promotion.

Quantifying crop production is one of the most important applications of remote sensing in which the temporal and up-to-date data can play very important role in avoiding any immediate insufficiency in agricultural production. A combination of climatic data and biophysical parameters derived from Landsat7 ETM+ was used to develop a mathematical model for wheat yield forecast in different geographically wide Wheat growing districts in Egypt. Leaf Area Index (LAI) and fraction of Absorbed Photosynthetically Active Radiation (fAPAR) with temperature were used in the modeling. The model includes three sub-models representing the correlation between the reported yield and each individual variable. Simulation results using district statistics showed high accuracy of the derived correlations to estimate wheat production with a percentage standard error (%S.E.) of 1.5% in El- Qualyobia district and average (%S.E.) of 7% for the whole wheat areas.

Remotely sensed data can be used to estimate biomass production using methodologies relating vegetation indices to light absorption or to leaf photosynthetic capacity. The considerations of both light absorption and photosynthetic capacity in remote sensing-based modeling to estimate biomass production or NPP was introduced based upon Monteith model NPP is one of a evaluation of land degradation. NPP was estimated from annual maximum NDVI by MODIS data. It was known that NPP of the grassland that except the forest and the farming ground was distributed between 50-200g /m2.

This paper provides empirical evidence on the reorganization of GVCs in East Asia, highlighting that structural trends explain a decrease in the fragmentation of production after 2011 but that it is not the result of rising trade costs along the value chain. Using harmonized inter-country input-output tables, the paper first analyzes the global import intensity of production to document changes in the structure of GVCs. It then calculates theory-consistent bilateral trade costs for intermediate and final products using an approach derived from the gravity literature and introduces a new index of cumulative trade costs along the value chain. These data are used to discuss whether the decrease in global imports is the consequence of shifts in demand, efficiency-enhancing strategies of firms or rising trade costs. Between 2011 and 2016, cumulative trade costs have decreased in East Asian GVCs. However, as COVID-19 is likely to intensify trade and investment uncertainties, trade costs could increase in the future. Policies aimed at reducing uncertainties and preserving the gains from trade and investment liberalization will be key in this new environment.

Objective: The purpose of this study was to examine the effect of changes in degrees of freedom of the fingers (i.e., the number of the fingers involved in tasks) on the task performance during force production and releasing task. Method: Eight right-handed young men (age: $29.63{\pm}3.02yr$, height: $1.73{\pm}0.04m$, weight: $70.25{\pm}9.05kg$) participated in this study. The subjects were required to press the transducers with three combinations of fingers, including the index-middle (IM), index-middle-ring (IMR), and index-middle-ring-little (IMRL). During the trials, they were instructed to maintain a steady-state level of both normal and tangential forces within the first 5 sec. After the first 5 sec, the subjects were instructed to release the fingers on the transducers as quickly as possible at a self-selected manner within the next 5 sec, resulting in zero force at the end. Customized MATLAB codes (MathWorks Inc., Natick, MA, USA) were written for data analysis. The following variables were quantified: 1) finger force sharing pattern, 2) root mean square error (RMSE) of force to the target force in three axes at the aiming phase, 3) the time duration of the release phase (release time), and 4) the accuracy and precision indexes of the virtual firing position. Results: The RMSE was decreased with the number of fingers increased in both normal and tangential forces at the steady-state phase. The precision index was smaller (more precise) in the IMR condition than in the IM condition, while no significant difference in the accuracy index was observed between the conditions. In addition, no significant difference in release time was found between the conditions. Conclusion: The study provides evidence that the increased number of fingers resulted in better error compensation at the aiming phase and performed a more constant shooting (i.e., smaller precision index). However, the increased number of fingers did not affect the release time, which may influence the consistency of terminal performance. Thus, the number of fingers led to positive results for the current task.

사회가 고도화되면서 복잡성은 증가하고 예측하기 어려운 리스크도 계속적으로 발생하고 있다. 특히 최근 코로나19 및 러시아-우크라이나 전쟁으로 인한 글로벌 공급망에 대한 리스크도 한 예라 할 수 있다. 공급망에 대한 리스크는 항만 물동량에 영향을 주어 항만운영과 항만산업 발전에 지장을 주게 된다. 본 연구는 글로벌 공급망 리스크가 항만 물동량, 특히 컨테이너 물동량에 주는 영향을 알아보기 위해 부산항 사례를 중심으로 글로벌 공급망 압력지수(GSCPI), 상하이 컨테이너 운임지수(SCFI), 산업생산지수, 소매 판매지수 등의 변수들이 물동량에 주는 영향에 대해 벡터자기회귀(VAR) 모형을 활용하여 실증분석을 시행하였다. 분석 결과, GSCPI의 상승은 단기적으로 부산항 물동량의 감소를 유발하지만, 일정 시점 후에는 물동량 증가요인으로 작용하는 파동의 형태로 영향을 주는 것으로 분석되었는데, 이는 비교군인 상하이항에서도 동일하게 나타났다. 다만 LA/LB항에서는 GSCPI가 물동량에 거의 영향을 주지 않는 것으로 나타났다. 또한 산업 생산지수와 소매판매지수는 부산항 물동량에 통계적으로 유의한 영향을 미치지 않는 것으로 나타났으며, SCFI의 경우 GSCPI가 물동량에 미치는 영향과 거의 유사한 것으로 분석되었다. 본 연구의 결과는 공급망 리스크가 점차 증가하고 있는 상황에서 리스크가 항만 물동량에 어떠한 형태로 영향을 미치는지를 밝혀 향후 공급망 리스크에 대비한 항만운영 정책 수립에 많은 시사점을 제공하고 있다.

The effect of dietary iodine and selenium supplementation, alone or in combination, on peripheral blood lymphocyte function was determined in laying hens. Eight-hundred-and-sixty-four New-Loman laying hens were randomly allotted into 12 dietary treatments with different inclusion levels of iodine (0, 0.1 and 0.2 mg/kg), selenium (0, 0.05, 0.1 and 0.2 mg/kg) or their combinations for 24 weeks. The lipopolysaccharide (LPS) stimulation index, concanavalin A (ConA) stimulation index, peroxide enzyme activity and phagocytosis to neutral red particles were tested. There were significant differences in LPS stimulation index, ConA stimulation index, peroxide enzyme activity and phagocytosis to neutral red particles in different iodine or selenium supplementation levels (p<0.05). The highest iodine and selenium supplementation both resulted in highest LPS-/ConA-stimulation indices (p<0.05). However, when iodine was lower than 0.2 mg/kg, the additional effect of different levels of selenium did not always result in significant differences in these indices. The results indicated that iodine and selenium may affect immunity in laying hens and, when the iodine level in the laying hen is lower than 0.2 mg/kg, a selenium allowance higher than 0.1 mg/kg may be necessary to improve immunity.
