This study aimed to investigate the changes in the ${\gamma}$-aminobutyric acid (GABA) content of bitter melon (Momordica charantia L.) cultivated from different regions, with different harvest times and at various maturation stages. Methods for observing the changes in GABA content were validated by determining the specificity, linearity, limit of detection (LOD), limit of quantification (LOQ), and precision and accuracy using the HPLC-FLD system. Results showed high linearity in the calibration curve with a coefficient of correlation ($R^2$) of 0.9999. The LOD and LOQ values for GABA were 0.29 and $0.87{\mu}g/mL$, respectively. The relative standard deviations for intra- and inter-day precision of GABA were less than 5%. The recovery rate of GABA was in the range of 98.77% to 100.50%. The average content of GABA was 0.93 mg/g and Cheongju showed highest GABA content of 1.88 mg/g. As the time of harvest increased from May to September, the GABA content decreased from 1.56 to 0.86 mg/g. Also, maturation of the bitter melon fruit was associated with a decreased in GABA content.

The charcoal has been used not only as fuel but also as human health care material since it was used. Charcoal's performances were generally investigated in aspects of energy efficiency and caloric values. This study was conducted in order to increase charcoal's application area and to develop functional paper. Five types of charcoal were used on a basis of gas absorption properties from previous study. Handsheets were made by two methods by internal loading and surface spray on interlayer. Strength properties of internal loading and interlayer spray handsheets were decreased as the charcoal loading increased. Ethylene gas absorption property was higher in both of oak's black charcoal and white charcoal than others. In terms of strength, 5-10% charcoal loading was efficient. Above 10% loading, a rate of strength decrease was higher than that of ethylene gas absorption rate. Formaldehyde absorption property was higher at both of oak's black charcoal and mixed charcoal than others. However, to guarantee enough charcoal loading should be higher than 95 $g/m^2$ for sufficient formaldehyde absorption.

Deoduk (Codonopsis lanceolata) has a complex chemical composition that includes polyphenols, saponins, amino acids, and other unidentified compounds. The contents of tangshenoside and lobetyolin are considered as standard of quality evaluation of Deoduk. In this study, an ultra-performance liquid chromatography (UPLC) method was developed for the quantitative determination of the two marker constituents, tangshenoside and lobetyolin. The methods for determining the standards of quality were validated by measuring their linearity, specificity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy using UPLC. Reversed-phase UPLC analysis was conducted quantitatively to identify individual tangshenoside and lobetyolin in Deoduk extracted with 50% (v/v) aqueous ethanol. We used 21 samples to carry out quantitative analysis of tangshenoside and lobetyolin. Based on their dry weights, the levels of tangshenoside and lobetyolin were 0.36~3.54 mg/g, 0.24~1.29 mg/g, respectively. These results will be valuable as basic data for standardization of Korean Deoduk.

홍화 (Carthamus tinctorius)는 오래 전부터 각종 감염성 질환이나 암을 치료하는데 효과가 있는 것으로 알려져 왔다. 최근 각종 천연산물에 사람과 동물의 건강을 증진시키는 효과가 있는 것이 밝혀지면서, 홍화의 면역조절 효과에 대한 관심이 높아지고 있으나 이에 대한 과학적 자료가 부족한 실정이다. 따라서, 본 연구는 홍화의 면역 조절 활성을 확인하기 위해 수행되었으며, 면역능 실험을 위해 주로 이용되는 실험용 닭(White Leghorn chickens)에게 홍화잎을 첨가한 실험식이를 3주간 급여한 후 관련 요인들을 분석하였다. 실험 결과, 홍화잎을 섭취한 실험동물에서 비장 면역세포의 증식이 많았고, $Y{\delta}$-TCR+ 세포의 비율이 높아졌으며, 십이지장에서는 IFN-Y, IL-8, IL-10, IL-15 및 NK-lysin 같은 사이토카인의 발현이 높아졌다. 따라서, 홍화잎은 식이와 함께 급여하였을 때 면역 증강 효과가 있는 것으로 밝혀졌으며, 홍화잎을 이용한 각종 제품 개발이 기대된다.

The purpose of this study is to investigate priority of cultural-environmental resource using the Analytic Hierarchy Process. Based on survey of expertise, a series of pairwise comparison judgements is performed to evaluate the relative strength or intensity of impact among the elements in the Hierarchy. This Study are applied three kinds of evaluation criteria and 40 kinds of cultural environmental resource. The results of this study are as follows. First, Traditional culture, landscapes, rural community vitality of Agriculture and Rural culture of environmental resources by establishing the concept of a comprehensive classification scheme are defined by the United Nations Food and Agriculture Organization (FAO) and the Rural Amenity Resources Multifunctionality in Agriculture. Second, Experts was considered important to "Continuity of history (43%),"> "Global importance (37%)"> "Notable characteristic (20%)" the order of the ratings on the importance of culture with rural agricultural and environmental resources. This is deemed the most important part of Continuity of history Third, The importance of the cultural and environmental resources comprehensive evaluation of the results, a strong tradition of building traditional sense or a landscape resource most highly were evaluated. and Vinyl greenhouse and warehouse such as agriculture, the current facilities required the relatively compared to other resources very low importance were evaluated. Resources, the importance of this study is judged to be able to be utilized as basic data in the selection criteria for the evaluation of the agricultural heritage.

The present conditions of Sanyangri village at Samcheok are stagnated and spiritless because there is only old men without young men. The purpose of this study is to make the basic plans of this rural and mountainous village to learn by personal experience. Therefore this study has been focused on its programs, land uses, roads and facilities how to activate it. The plan orientation of it is to make and become active by tourists to visit this village to experience the rural and mountainous living culture. So the general plan is divided into two zone which are the rural experience zone and the mountainous experience zone. Also the plan is to be considered to increase its amenities through the connection of surrounding villages and their resources.

In spite of the government policies and incentives to revitalize rural areas, we still have a lot of problems such as the environmental degradation in rural areas, widening gap in living conditions between urban and rural areas, and decreasing rural populations. This paper aims to suggest a new planning model for ecotourism based rural villages and develop a village revitalization plan for Jangwha-ri in Gangwha Island. The new model emphasizes sustainable development based on local indigenous resources and resident initiatives.

Objective: Oxidative stress (OS) is a pathological process arising from the excessive production of free radicals in the body. It has the potential to alter animal gene expression and cause damage to the jejunum. However, there have been few reports of changes in the expression of long noncoding RNAs (lncRNAs) in the jejunum in piglets under OS. The purpose of this research was to examine how lncRNAs in piglet jejunum change under OS. Methods: The abdominal cavities of piglets were injected with diquat (DQ) to produce OS. Raw reads were downloaded from the SRA database. RNA-seq was utilized to study the expression of lncRNAs in piglets under OS. Additionally, six randomly selected lncRNAs were verified using quantitative real-time polymerase chain reaction (qRT-PCR) to examine the mechanism of oxidative damage. Results: A total of 79 lncRNAs were differentially expressed (DE) in the treatment group compared to the negative control group. The target genes of DE lncRNAs were enriched in gene ontology (GO) terms and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathways. Chemical carcinogenesis-reactive oxygen species, the Foxo signaling pathway, colorectal cancer, and the AMPK signaling pathway were all linked to OS. Conclusion: Our results demonstrated that DQ-induced OS causes differential expression of lncRNAs, laying the groundwork for future research into the processes involved in the jejunum's response to OS.
