The purpose of this study was to analyze leadership competency in the rural leader roles. The data were derived from 317 leaders in 97 rural communities by questionnaire. SPSSWIN/ver10 was adopted t-test and IPA (Importance-Performance Analysis) methods employed. The major findings of this study were as follows; Rural leaders should concentrate on developing coaching/feed back, program management skills, and presentation skills. Administrative head of village should pay attention to benchmarking, brand development and conflict resolution rather than resident management, service knowledge, and making relationships. Leaders of village development council should concentrate on brand development, benchmarking, and educating residents. Head of women's organizations should concentrate on developing assessments, educating residents, and resolving conflict skills, whereas members of Samaeul organization should try to concentrate on program management, coaching/feed back and presentation skills. Rural leaders showed different leadership competency by the IPA. Therefore, this study suggested that leadership education for rural leaders should consider leadership competency.

Frequent hydro-meteorological events caused by global climate change and human exacerbate activities, make the water resource problem more complicated. The increasing speed urbanization brings a significant impact on the city flood control and security, water supply safety, water ecological security, water environment safety and the water engineering security in China, and puts forward higher requirements to urban water integrated management, undoubtedly which become the biggest obstacle for water ecological civilization construction, thus urgent requiring an advanced methods to enhance the effectiveness of the water integrated management. The other fields of smart ideas point out a development path for water resource development. The construction demand of smart water resource is expounded in the paper, combining the philosophy of modern Internet of things with the application of cloud computing technology. The concept of smart water resource is analyzed, the connotation characteristics of smart water resource is extracted, and the general model of smart water resource is refined. Then, the frame structure of smart water resource is put forward. The connotation and the overall framework of the smart water resource represent a higher level of water resource informationization development and provide a comprehensive scientific and technological support to transform water resource management from an extensive, passive, static, branch and traditional management to a fine, active, dynamic, collaborative and modern management.

Astilbe rubra (AR) is a perennial, belongs to the Saxifragaceae family, it contains tannin and triterpene. AR has been used in republic korea to improve toxication, fever, pain and convulsion. Recently, number of natural products have been analyzed for potential pharmacological activities including anti-cancer, anti-obesity and anti-diabetic medication. Consequently, we investigated the growth inhibition effect of Astilbe rubra water extract (WAC), ethanol extract (EAC) and bergenin on Hela cell (human adenocarcinoma cell). From whole plant of A. rubra, bergenin was isolated by column chromatography and its structures were identified by $^1H$, $^{13}C$ NMR and IT TOF-ESI MS. High extraction efficiency of bergenin was shown at 0.95% under 60 min reflux extraction with 50% MeOH. The MTS assay showed that EAC (ethanol extract) treatment increased cell death in a dose-dependent manner. Moreover, EAC treatment on Hela cell increased apoptotic cell death and caspase-3 activity. Results suggest that EAC has growth inhibition effect on Hela cells, but not WAC and bergenin. $500{\mu}g/mL$ EAC treatment inhibited Hela cell at $60.2{\pm}1.5%$.

In the course of our continuing search for biologically active components from Korean medicinal plants, we isolated the main compound, luteolin 5-glucoside from aqueous fraction of Ajuga spectabilis. The structure was elucidated by the basis of $^1H$ and $^{13}C$ NMR and TOF ESI-MS data. Quantitative analysis of luteolin 5-glucoside was carried out on a XBridge C18 column ($S-5{\mu}m$, $4.6{\times}250mm$) with gradient elution composed of acetonitrile:water. The results exhibit that the average content of main compound in A. spectabilis were 0.048%. Oxidative stress plays a major role Alzheimer's disease (AD) and other neurodogenerative disease. AD is major health problem and there is currently no clinically accepted treatment to cure or stop its progression. Pretreatment with luteolin 5-glucoside markedly attenuated $H_2O_2$-induced cell viability loss in a dose-dependent manner. Luteolin 5-glucoside also inhibited the formation of intracellular reactive oxygen species in SH-SY5Y. The results suggest that luteolin 5-glucoside from A. spectabilis has protective effects against oxidative stress-induced cytotoxicity, which might be a potential therapeutic compound for treating and/or preventing neurodegenerative disease implicated with oxidative stress.

In traditional Korean medicine, Osmunda japonica Thunb has been used as hemostasis and antipyretic treatment. The main compound "cinnamtannin B-1" was obtained by column chromatographic separation, and its structure was determined by spectroscopic methods, including $^1H$, $^{13}C$ NMR, and IT-TOF-ESI MS. Ash, moisture and extract content and acidinsoluble ash were monitored as identification test to establish the analytical methods. The optimum reflux extraction condition was 100% methanol extracted 30 min for 2 times. A quantitative analysis using HPLC method exhibited that the main compound at 24.7 min and its content was 0.96% in methanol extraction.

We describe two penaeoid shrimp, Hymenopenaeus equalis and Metapenaeus ensis, that were collected from an area northwest of Jeju Island and are new to Korean waters. Hymenopenaeus equalis is the first Korean representative of this genus. A brief distributional and morphological description of the two species is provided.

The purpose of this study was to develop the strategy on activation of village by forest healing. Researcher conducted the questionnaire survey for forest healing village development to classify the mountain's characteristics by the three factors(linkage resource, program, facilities). In result, village characteristics were divided into two types: single element outstanding type(resource), complex element outstanding type(resource+program, resource+facilities). The development of forest healing village have to focused on the forest healing service recipient and mountain village characteristics. In conclusion, relationship between forest healing recipient and mountain characteristics was as follows: single type (resource) - public; complex type (resource+program) - chronic disease, social vulnerable people; complex type (resource+facilities) - severe disease. The detailed guideline for forest healing village needs to be established according to the mountain characteristics.

This study was conducted to evaluate the effect of seed disinfectant, in control of brown leaf blight, growth characteristics, and dry root yield in the cultivation of Alisma plantago after early maturing rice cropping. Experimental plot was laid out in split plots design with three replications. The major seed disinfectants were benomyl Wp, 20%, Captan Wp, 50%, Triferine Ec, 17%, Etridia zole Ec, 25%, and Thioplant-mythyl Wp, 50%. Even though seed disinfectant treated had no effect on the growth and flowering date of Alisma plantago, dry root yield was increased largely with benomyl Wp, 20%, in seed disinfectant than in the other seed disinfectants and contorl. All seed disinfectants had no injury with standard dosage. But all seed disinfectants had slight injury in the double dosage level for the Alisma plantago. On the basis of yield, vegetative and disease paramerer, benomyl Wp (20%) ($100g/20{\ell}$) had shown superior performance, however, all the seed disinfectants are effective as compare to without treatment.

미래 신 성장동력이며 융합산업의 핵심 도메인인 IT 산업은 타 산업과의 융합을 통하여 국가 발전의 기반이 되는 산업이지만, IT 고급인력의 부족 현상은 지방과 수도권에 한정되지 않고 지속되고 있다. 그러나, 그간의 연구들은 포괄적인 인력양성에 대한 연구가 주를 이루고 있으며, 사업수행 지역의 특성화를 이룰 수 있는 인력양성 정책에 대한 성과분석에 대한 연구들은 미흡한 실정이다. 이에 따라, 지역의 IT 고급 인력을 양성하여 IT 융합을 기반으로 지역산업을 활성화하고 이를 통하여 지역을 발전시키기 위한 제도적 개선방안에 대한 필요성이 나타나고 있다. 따라서 본 연구에서는 지역의 IT 인력양성 활성화를 위하여 지역 기반 인력양성사업의 IT 분야 성과분석을 통하여 제도개선방안을 설계하고자 한다.
