In the Gangwon province, severe freezing damage to road tunnels are occurred due to freezing condition such as snowfall, cold waves and icing. As a result, serious damage occurs on the lining and road surface of the tunnel entrance and exit. Therefore, it is necessary to develop appropriate mitigation methods to protect damage to people and property by freezing. In this paper, we introduce that the trend of research for reducing the freezing damage and the required performance to be secured for the maintenance of road tunnels in cold region and the future research plans.

Average concentration of PM in Seoul metropolitan area satisfied the Korean air quality standard in 2010. Furthermore, concentration of PM in all boroughs across Seoul met the air environment standard in 2012. PM10 concentration was relatively higher in center of Seoul in comparison to the rest, while PM2.5 concentration showed exactly the contrary result. We analyzed the effect that PM emissions from vehicles would have on PM concentrations across Seoul. The results showed that average annual PM concentration recently decreased in Seoul although the number of vehicles registered annually continued its upward trend. By contrast, average fine dust concentrations in Seoul showed a decline which suggested that correlation between annual average PM concentrations and number of registered vehicles remained low. However, year-on-year vehicle registration rate recently showed a declining tendency in the same way as the trend of changes in average PM concentrations. Particularly, the upward trend in annual average PM concentrations in 2002 and 2007 was consistent with the increase in vehicle registration rate, suggesting that vehicle registration rate was closely associated with changes in PM concentrations.

국내 컨테이너 화물의 수출이 수입에 비해 감소하면서 특히, 경인지역 내 공 컨테이너의 순환 문제가 심각한 수준에 이르렀다. 이 에 경인지역 내 공 컨테이너 반납지(의왕 ICD 및 인천항)에는 공 컨테이너가 계속해서 쌓여 가고, 일부 선사들은 공 컨테이너의 부산 반납을 의무화하여 업계 내 마찰까지 발생하는 상황이다. 본 연구는 이와 같은 경인지역 내 공 컨테이너 반납처리 문제를 개선하기 위하여 경인지역 의 공 컨테이너의 반납처리 실태를 파악하고, 그에 대한 개선 방안을 제시하였다. 이때, 개선방안을 선사 입장이 아닌 컨테이너 이용 주체 입 장에서 제시하고자 화주 및 운송업체, 컨테이너 운송기사 등 실질적인 이용자를 대상으로 반납지에 대한 문제점 및 선호도를 파악하고, 종합 물류기업 A사의 운영 자료를 바탕으로 비효율적인 비용 구조를 분석하여 경인지역 내 공 컨테이너 반납처리 문제가 심화될 수밖에 없는 근 본적인 원인을 도출하였다. 경인지역 내 문제점을 해결하기 위해서는 인천항 기능의 재정립, 경인지역 내 제3의 신규 장치장 확보, 효율적인 공 컨테이너 순환체계 확립 등이 필요함을 제시하였고, 이를 위한 국가 차원의 법·제도 마련 등이 시급함을 시사하였다.

The purpose of this study is to uncover the characteristics of spatio-temporal patterns and synoptic climatic patterns of thermodynamic föhn phenomenon accompanying orographic precipitation across Mt. Halla for the recent several decades. Analyses of surface observational data reveal that thermodynamic föhn days occur mainly between mid-spring and early summer (April-June) particularly in the form of North warm-South wet type across Mt. Halla due to the accelerated moisture advection around a migratory low pressure. In extreme cases of thermodynamic föhn across Mt. Halla, more than 6.0°C of daily mean temperature difference between windward and leeward sides is observed though its spatial patterns vary seasonally. Composite maps of upper synoptic climatic variables for multiple strong föhn days show that the relative position and intensity of a migratory low or high pressure anomaly cores as well as of semi-stationary fronts and air masses affect the seasonal spatial patterns and severity magnitudes of thermodynamic föhn around Mt. Halla. These results provide a scientific basis for developing a proactive föhn prediction system to reduce potential damages of föhn phenomenon to local economic activities in Jeju Island.

This study was carried out to identify the optimum seeding dates for selecting a double-cropping system and to assess the effect of polyethylene film mulching on the yield of Proso millet. Seeds of the varieties Hwanggeumgijang and Ibaegchal were sown in Miryang on five different dates: 1st (May 25), 2nd (June 15), 3rd (June 25), 4th (July 5), and 5th (July 15), with and without polyvinyl mulching. The varieties have different characteristics, for example, Hwanggeumgijang is an early-maturing type and more sensitive to temperature, whereas Ibaegchal is a medium-maturing type and more sensitive to the duration for which it is exposed to sunlight. Late-sown Hwanggeumgijang had a short heading date from seeding and required a low accumulated temperature. It also had a shorter period of heading, a shorter culm length and a shorter diameter of stem. In contrast, it had had a higher number of ears per m2 although similar ear length and similar 1000-grain weight. The yield potential of Hwanggeumgijang was found to decrease at a late seeding date. In particular, it significantly decreased at the seeding date of July 15. In the case of cultivation with polyvinyl mulching, the period of heading was shorter by 2–4 days and the yield potential was increased by approximately 12–32%. The length and diameter of culm in Ibaegchal were slowly decreased, but the length of ear, the 1000-grain weight and the yield potential were similar for all seeding dates (except July 15) and cultivation with and without mulching. When sown late, the length and diameter of the culm of Ibaegchal very rapidly decreased by the July 15 seeding date. The protein content of Ibaegchal was higher but the amlyose content of Ibaechal was lower compared to Hwanggeumgijang. At late seeding dates, the protein contents of the two varieties increased but the amylose contents were similar.

The purpose of this study is to investigate pronunciation deviations of German diphthongs for Korean learners residing in Daegu and Gyeongbuk regions. When Korean learners utter German diphthongs such as /a͜i/, /a͜u/ and /ɔ͜y/, this study is to analyze what phonetic features appear to be realized in segmental and suprasegmental perspectives and find out the reasons to eventually contribute to reducing Korean learners’ pronunciation deviations of German diphthongs. The results of the experiment are as follows. First, when Korean learners utter German diphthongs, they were realized mostly in two syllables. Second, as to the descent degree of intensity in a suprasegmental perspective, the difference in a case of intensity realization of /a͜i/ between Korean learners and Germen speakers was shown to be the biggest. Third, in terms of length (utterance duration), the biggest difference with German speakers was shown to be found when Korean learners uttering /a͜u/. Fourth, in a segmental perspective, the pronunciation deviation of /ɔ͜y/ was found to be the biggest. The reasons that these pronunciation deviations appeared may include the negative transference phenomenon of mother tongue that worked on deviations the most, and other correlations with lack of awareness of phonetic rules about the relations of German grapheme‐phoneme rules, phonetic features of German diphthongs,—for instance, features including a single syllable utterance, and/or the feature of intensity descent of syllables when consecutively connected to non‐syllables.

Since FAO introduced the Globally Important Agricultural Heritage Systems(GIAHS) in 2002, 36 sites of 15 countries so far have been listed on GIAHS. This study aims to find the important agricultural heritages of Korea and to prepare the methods for them to be selected as GIAHS. We have analyzed the proposals of the 36 GIAHS listed in order to study the characteristics of their components of the agricultural heritage which worked for being selected. To analyze the components of the agricultural heritage first, agricultural heritage was classified into 13 types and 42 components in light of GIAHS criteria. Then central themes were set to analyze the relevant contents in the proposals. They were, the type of GIAHS Site, significant agricultural landscape, the agriculture-forestry-fisheries-livestock linkage systems, the multi-layered, inter-cropping, circulation cultivation systems, the soil and water management systems, the conservation of agrobiological diversity and genetic resources, the history of the agricultural heritage, the succession of traditional farming techniques, the cultural diversity and so on. Most GIAHS are located in mountains, grasslands, rivers and coasts, desert than in plains, through which GIAHS assure us that it is the heritage of human challenge to overcome the harsh geographic environment and maintain a livelihood. In these sites the traditional farming techniques are carried on, such as mountain clearings, terraced rice paddies, and burn fields, and the unique irrigation systems and agricultural landscapes are well maintained, and the eco-friendly traditional farming techniques utilizing abundant forest resources and agriculture are well handed down. The origin or home of crop growing, a variety of genetic crop storage, the world’s largest crop producer and preserving cultural diversity are also important factors for the selection.

In recent years, the population structure has been changed by the progresses of 6th-industrialization and transportation in farming areas. This study aims to suggest a regional development plan of farming areas in accordance with the demographic changes. Population structure indicators were derived from previous studies and literature review in order to identify the types of farming areas. Demographic indicators separated to depopulation and population growth in farming areas through a standardized scoring method. This research found that the division of economy is not only the most important division in any other regional development divisions but also necessary to develop new sources of non-farm income through traditional culture, natural environment. In the social division, it is necessary to secure the facilities for the formation of a sense of community to multicultural families and existing residents in farming areas. In the environmental division, it is desirable to improve the quality and satisfaction of life for residents such as the sidewalk and park that utilize ecological environment, culture, history for both depopulation and population region. In the physical division, there is a need for improvement of the facilities of basic living infrastructure service such as roads, water supply and sewerage systems. In the institution division, sustainable financial support of the central government policy for farming areas is crucial for the improvement of residential environment in the farming areas of depopulation and population region.

On the purpose to analyze the survival rate of startup companies since their establishment, the companies’ survival rate was investigated by surviving period. The average and coefficient of variation(C.V.) of the startup companies’ survival rate were examined with the comparison of urban and rural areas, and primary, secondary, and tertiary industries. In this study, the variation of total numbers of new-established companies, from 1998 to 2012, were analyzed with micro-data of the Statistics Korea, ‘The Census on Establishments’. The results show that the survival rate of primary industry companies largely fluctuate and don’t be stabled during the whole surviving periods, whereas secondary and tertiary industry companies show stabilized survival rate after fifth year from their establishment. Especially, the startup companies of primary industry located at urban areas show the largest fluctuation and the most vulnerable stability of survival rate. It is concluded that the surviving period of primary industry companies don’t guarantee their survival, while survival rate of secondary and tertiary industry company became stable after five years from their establishment.

Aging phenomenon is an important issue in Korea national policy. This aging phenomenon depends on the social and environmental characteristics of regions. Also aging phenomenon and regional characteristics have spatial dependency. The purpose of this study is to discover the spatial changes in aging population rate and to find local factors of regional aging phenomenon considering spatial autocorrelation. For spatial analysis of ageing phenomenon, local Moran’s I and Geographically Weighted Regression (GWR) were applied. As the results, the most significant changes of aging phenomenon appeared between 2000 and 2005, and most of hot-spot regions (aged regions) were distributed in Jullanam-do and Jullabuk-do. The results of GWR (R-square: 0.681) shows that total fertility rate, the number of doctor per 1,000 people and forest area rate have positive relation with aging population rate, but the number of private academy per 1,000 people has negative relation.

The purpose of this study is to analyze the present situation of the landscape management - which encompasses landscape ordinance, planning, and agreement - in regards to the Shiga prefecture and Omihachiman city to explore sustained landscape preservation and management methods, and to deduce the implications of the establishment of rural landscape planning and landscape administration. The conclusion is summarized as follows. First, the landscape ordinance should be operated so that the practical landscape management is suitable to the characteristics of local governments. Second, landscape management should be based on zoning. The landscape plan should start with defining the types and characteristics of the landscapes at each site and subdividing the landscape areas accordingly. Third, the restriction of conduct and the promotion of autonomous landscape activities should be employed as the two axes of landscape administration. Beautiful and healthy landscapes can be achieved through collective efforts of the community, and this requires voluntary practice amongst individuals and administrative regulations to achieve so. Fourth, meticulous, dimensional and practical landscape plans should be established. In order to effectively preserve, form and manage the essential landscape elements and resources of the area, the starting landscape plan should be more definitively outlined. Finally, it is necessary to change the perception of landscape. In order to relish beautiful and healthy scenery, it is critical to recognize the value of the attentive efforts and dedication of each member of the community that stimulates the objective.

Public transportation is public service that is contributed to the convenience of the public. However, opportunity for public services in rural areas is weaker than the chance in urban areas. The purpose of this study is to evaluate accessibility of various public facilities using public transportation. To evaluate the accessibility, we calculate the various time from community center to the nearest bus stop, walking time, riding time in bus, and waiting time for transfer. The results of this study ares as follows; (1) Villages occupy 19.8% in rural areas that walking time from community center to the nearest bus stop takes over 10 minutes in integrated Chungju-si; (2) The average speed is 21.9 km/hr estimated to departure and arrival time of bus route; (3) The accessibility time from community center using the average bus speed takes 15.43 minutes to public facilities, 35.15 minutes to emergency center, 8.70 minutes to medical center, 9.70 minutes to elementary school, 16.26 minutes to middle school, and 22.61 minutes high school; (4) The transfer time of public transportation takes 13.46, 21.96, 10.48, 7.78, 11.11, 16.10 minutes to public facilities, emergency center, medical center, elementary school, middle school, and high school, respectively; (4) Traffic accessibility using bus vehicles in the East and South Chungju-si is lower than areas in the West and North Chungju-si. Some villages surrounding public offices (eup-myeon office) which have a high density of population, indicate a high traffic accessibility.

본 연구는 부산광역시 거주민을 대상으로 원전주변 갑상선암 피해 소송 이후 원자력발전소 인근지역과 시내권에 거주하는 주민간의 인식 차이를 분석하여 국민들의 원자력에 대한 수용성 수준을 판별하고자 하였다. 설문조사는 총 551명(원전인근지역 269명, 시내권 282명)을 대상으로 대인면접을 통해 이루어졌으며, 분석 결과, 원전 주변 갑상선암 발병 피해 소송 사건을 계기로 국민들의 원자력에 대한 인식에 변화가 있는 것으로 나타났다. 원전인근지역 주민의 경우 사건 이후 원자력에 대한 불신과 불안감이 높아져, 원자력에 대한 부정적 인식이 강해졌음을 확인할 수 있었다. 반면 시내권 주민들은 원전 주변 갑상선암 발병 피해 소송 사건에도 불구하고 사건 이전보다 더욱 원자력 수용성에 긍정적인 인식을 갖는 것으로 분석되었다. 그러나 원자력 안전성과 신뢰성에 대한 인식은 부정적인 것으로 분석되어 원자력 수용성과 상반되는 이중적인 인식을 보였다. 이는 부산광역시 시내권 주민들의 경우 원자력의 편익, 필요성 등을 원칙적으로 인정하나 안전성에 대해서는 의심하는 것으로 판단되며 향후 원자력의 이용 확대를 지속적으로 추진하기 위해서는 국민의 올바른 이해와 신뢰 그리고 무엇보다 국민 또는 원전인근지역 주민들과 충분한 의사소통이 필요하다고 사료된다.

Concentrations of hydrogen sulfide in ambient air have been measured from January 2014 to June 2016 in a coastal area near the Ulsan National Industrial Complex. The measurement sites were 1 km, 2.6 km, 5.6 km, and 20 km away from a kraft pulp mill, which is located at the most southern edge of the complex. Concentrations above 0.4 ppb were monitored every 5 min and the highest concentration of the day was determined. From a total of 775 measurement days, hydrogen sulfide concentrations > 20 ppb were recorded on 36 and 38 days at the measurement site closest to the mill and the residential area 2.6 km away from the mill, respectively. At the site farthest from the mill, the concentrations were always 20 ppb lower than the malodor regulation for the residential area but sometimes higher than the odor recognition threshold for hydrogen sulfide. Although several emission sources of hydrogen sulfide have been published in the Pollutant Release and Transfer Register of Korea, the kraft pulp mill is considered to be the biggest contributor of atmospheric hydrogen sulfide in the southern coastal area of Ulsan.

To analyze the cooling effect of urban green areas, we conducted micrometeorological measurements in these areas and their surroundings in Seoul, Korea. From the average hourly temperature measurements through each month for the last two years (March 2013 to February 2015), we found that the maximum temperature difference between urban and green areas was about 2.9℃ at 16:00 LST in summer, and the minimum was about 1.7℃ at 22:00 LST in winter. In summer, the temperature difference was the largest during the day, rather than at night, due mainly to shading by the tree canopy. The specific humidity difference between the two areas was about 1.5 g kg-1 in summer, and this decreased in the winter. The specific humidity difference between urban and green areas in summer is relatively large during the day, due to the higher evapotranspiration level of biologically active plants.

This study is aimed at identifying the distribution of vascular plants growing at Byeollipsan(Mt.), Bongchunsan (Mt.) and Gucksoosan(Mt.) in Ganghwa isand. Field surveys were conducted for each season from March 2015 to October 2015. The flora of study area were found to be of 455 taxa, 93 families, 280 genus, 392 species, 4 subspecies, 53 varieties and 6 forma. Rare plants were found to be of 3 taxa. Among them, rare plant species consisted of endangered species (EN degree):1 (Thalictrum simlex var. brevipes Hara), vulnerable species (VU degree): 2 (Wikstroemia trichotoma (Thunb.) Makino, Scorzonera albicaulis Bunge), respectively. In all the surveyed areas, a total of 6 taxa (Clematis brachyura Maxim. etc.) were found to be endemic to Korea. The floristic special plants found in the surveyed areas were 1 taxa of grade Ⅴ, 4 taxa of grade Ⅳ and 8 taxa of grade Ⅲ, respectively. The naturalized plants were identified as 29 taxa and included Fallopia dumetorum (L.) Holub, Ambrosia artemisiifolia L., Aster pilosus Willd. etc..

Background : Most of cases in korea, distributed herbal medications are storaged in room temperature and it causes many insect pests during storage. Despite the fact, there is little research about storage conditions. Temperature and humidity in storehouse are highly related with pests’ overwintering, generation length and the number of occurrence in summer. Consequently, in this research, major pests’ overwintering was studied by reviewing facility condition, temperature and humidity in major regional storehouses. The results of this would help to develop how to manage pest occurrence in distributed herbal medications. Methods and Results : For this study, storage facilities was investigated at different regions including Gyeongdong Market in Seoul, the pharmaceutical company in Daegu and farmhouse in Youngcheon by monitering temperature, humidity, ventilator, air conditioning and heating on ground and underground places from June 2014 to July 2016. including Upon investigation, most of building using for storage had simple ventilators. Whereas in case of farmhouse, it is vulnerable to maintaining quality. Because most farmhouse had temporary buildings which are difficult to control temperature and humidity. In addition, among the other surveyed warehouses, Basement in the Gyeongdong Market had most favorable condition for pest overwintering. The lowest temperature of it was seldom below zero maintaining level of about 1.5℃ and average temperature was about 10℃ in underground warehouse during winter. And the ground warehouse of Daegu had similar patterns in temperature and humidity with that of Seoul in that being over 0℃ even in the winter. In Youngcheon, the temperature of farmhouse was below zero degree and the daily range of temperature and humidity was wide. It caused difficulty of overwintering of insect pests but possible to inhabit. Conclusion : According to a study by Han-Mo, Koo(1997), it was impossible to overwinter for Lasioderma serricorne F. which is dominant medicinal plants’ pest in north of the Chungcheong region’s warehouse due to low temperature. But in case of investigated warehouses, it was possible to overwinter because of the high temperature in office building or basement storage area. In order to make prediction of pest occurrence and comprehensive measures, it is urgent to take more investigation by regional groups and types of storage.
