  • We pursue empirically influential determinants of risk-sharing across various groups in the United States. We consider all the possible combinations out of the eight BEA economic regions and relate the risk-sharing measure for each group to sectoral composition difference under the control of the state-level macroeconomic and financial characteristics. Our results show that more active risk-sharing via cross-ownership market is observed in groups exhibiting more different sectoral composition. The evidence implies that, given other economic and financial conditions equal, economic union tends to share more consumption risk among its members that are more heterogeneous in their sectoral composition. These days, many countries aim to form FTA and other forms of economic integration. We suggest that they should pay attention to sectoral composition for member countries to minimizes income shock in the integrated economy.

  • Purpose: The purpose of this study is to evaluate the validity and reliability of the Korean Bereavement Care Confidence Scale (K-BCCS). Methods: The Perinatal Bereavement Care Confidence Scale (PBCCS) was translated into Korean according to an algorithm of cultural adaptation process and excluded six items which were specific to perinatal bereavement. A total of 229 clinical nurses participated in the study. Construct validity, convergent validity, discriminant validity, and group comparison validity were evaluated, and Cronbach's α was calculated to estimate the reliability of the K-BCCS. Results: The K-BCCS consisted of 31 items in 7 factors, including knowledge and skills for bereavement care (12 items), organizational support (6 items), awareness of the needs (3 items), interpersonal skills (3 items), workload influence (2 items), continuous education (2 items), and understanding the grief process (3 items). The factor loading of 31 items within the 7 factors ranged from .60 to .86. For the convergent validity, the construct reliability (CR) ranged from .74 to .94, and the average variance extracted (AVE) ranged from .49 to .73, which is considered acceptable. The discriminant validity showed that the AVEs of the subscales were greater than the square of the correlation coefficient r. The nurses who had experience providing bereavement care (t=4.94, p<.001) or had received bereavement education (t=6.64, p<.001) showed higher K-BCCS values those without experience. The Cronbach's α of 31 items was .93 and ranged from .60 to .94 per subscale. Conclusion: The K-BCCS is a valid and reliable tool for evaluating nurses' confidence in bereavement care.

  • This essay examines the questions that existing high-teen related studies are missing: "What is high-teen?". It is a foreign language originated from Japanese, spoken only in Japan and Korea among the post-war pan East Asian pop culture scenes. High-teen is based on the 'teenager' formed in the United States. It should be understood not just as a subcategory of popular culture but as an important ideological allegory of post-war Japanese politics. To learn this concept, this essay archeologically researches the origin of high-teen's meaning and analyses the political meaning of the early high-teen contents of Ueda Hirao which related to postwar politics and ideology in Japan. Existing research regarding high-teen tends to be limited to the peripheral and fragmentary areas. On the other hand, this paper will be the beginning of a discussion on high-teen in a more expanding perspective as an East Asian postwar history.

  • SWAT (Soil and Water Assessment Tool)은 미국 농무성 농업연구소에서 개발된 준분포형(semi-distributed) 수문 모형으로 복합토지이용유역에서 장기간에 걸친 다양한 종류의 토양, 토지이용 및 토지관리 상태의 변화에 따른 유역의 유출량, 유사량 및 영양물질의 영향을 예측하기 위해 개발되었다. SWAT은 기본적으로 다양한 매개변수에 대한 수동 보정 기능을 제공하고 있지만 매개변수 보정에 따른 모의결과의 불확실성을 수반하게 된다. 이러한 문제를 해결하기 위해 자동보정 기능을 제공하는 SWAT-CUP (Calibration and Uncertainty Program)이 개발되었다. SWAT-CUP에서 제공하는 매개변수의 최적화 과정에서 유사한 모의 결과를 산출하는 수천 개의 매개변수조합이 존재하기 때문에 보정기법의 선택에 따라 최종 매개변수의 값이 달라질 수 있다. 불확실성을 발생시키는 요인으로 (1) 매개변수의 선택, (2) 보정 기법, (3) 목적함수, (4) 매개변수의 초기 범위, (5) 모의(simulation)의 실행(run) 및 반복(iteration) 횟수, (6) 위치, 개수 등 보정 자료의 선택 등이 주로 지목된다. 이러한 요인으로 발생하는 불확실성은 SWAT 모형의 구조 및 입력 자료에서 기인하는 것으로, 사용자의 설정에 따라 크게 좌우된다. 본 연구에서는 SWAT 매개변수 보정 과정에서 발생할 수 있는 불확실성을 평가하고, 효율적인 보정 방안을 제시하기 위해 수행되었다. 낙동강 권역의 내성천 유역을 대상으로 SWAT 모형을 구축하였으며, 내성천 본류에 위치한 수위(유량) 관측소의 자료를 활용하여 검·보정을 수행하였다. 모의 결과는 유량의 크기 뿐 아니라 유량의 발생 시기, 유역의 반응 및 증가·감소 경향성을 함께 고려하여 평가하였다. 그 결과 모형 구조에 따른 불확실성의 전이과정을 정확하게 파악하는 것은 불가능하지만 SWAT 모형의 비고유성(non-uniqueness)에 의한 불확실성을 정량화하여 나타내었다.

  • 본 연구의 목적은 HSPF(hydrological simulation program-FORTRAN) 모형을 이용하여 기후변화에 따른 남한의 유출량 변화를 분석하는 데 있다. 상세화 작업을 수행한 13개의 GCM(global climate model)을 이용하여 기후변화 시나리오를 구축하여 미래 유출량을 추정하는 데 사용하였다. 미래 유출량을 생산하기 위해 앞에서 선정한 13개 GCM을 사용하여 수문기상자료를 구축하였다. 모의기간은 S0: reference period (1976-2005), S1: near future period (2011-2040), S2: mid-century period (2041-2070), S3: distance future period (2071-2100) 총 4개로 구분하였다. 공간적으로는 109개 중권역을 대상으로 HSPF 모형을 모의한 다음 최종적으로 남한을 대상으로 분석하였다. HSPF 모형의 매개변수 보검정은 장기간의 일별유량자료가 구축된 총 6개 댐 상류유역을 선정하여 수행하였다. 유출량은 기본적으로 강수량과 증발산량에 굉장히 영향을 받으며, 미래 수문기상자료를 분석한 결과 남한의 강수량과 증발산량이 모두 증가하는 경향을 보인다. 다만 강수량의 상대적인 변화가 증발산량의 변화보다 크기 때문에 전반적으로 미래 유출량을 증가하는 것으로 분석되었다. 특히 미래 강수량은 미래 변동성이 굉장히 큰 특징을 가지고 있으며 이러한 이유로 미래 유출량의 변동성도 큰 것으로 분석되었다. 계절적으로 살펴보면 여름과 가을의 미래 유출량이 증가하고 겨울에는 감소하는 것으로 분석되었다. 가을과 겨울의 변동성이 매우 큰 특징을 보이며 미래 극한 홍수와 가뭄의 출현 빈도가 높아질 것으로 보인다. 본 연구 결과는 남한의 기후변화 적응 대책을 수립하는 데 있어 기초자료로 활용할 수 있을 것으로 사료된다.

  • 물관리 일원화, 물관리기본법 제정·시행 등 우리나라 물관리 체계의 혁신기에 정책의 구심점 역할을 수행할 통합 물관리 전략 마련이 요구됨에 따라, 최근 관계부처 합동으로 「제1차 국가물관기본계획(2021~2030)」을 수립하여 공표·발간되었다. 국가물관리기본계획에서는 유역단위의 물관리를 원칙(12대 기본원칙 중(中))로 하며, 물관리 3대분야(수질·수생태, 이수, 치수)에 대한 추진전략을 수립하였다. 또한, 지속가능한 물관리 체계를 구축하기 위해 추진전략별 주요 관리지표를 설정하였으며, 이를 통해 물관리 방향을 정립하고 분야별 관련 및 하위계획과의 일관성·정합성을 유지하고자 하였다. 이에 본 연구에서는 추진전략별 주요 관리지표 중, 유역 재해안전도와 관련하여 하천범람에 대한 기존의 치수안전도의 한계점을 검토하고 유역단위의 치수관리 현황을 평가 할 수 있는 방안을 마련하고자 하였다. 과거 유역종합치수계획에서의 치수안전도는 홍수피해잠재능(PFD)을 적용하여 등급별 홍수방어대책 수립방향 및 하천의 설계빈도 조정을 검토하였으며, 홍수피해잠재능(PFD)의 실무적 적용 어려움(산정인자 다(多)), 설계빈도와의 연계성 부족, 치수단위구역의 공간적 정확성 미흡 등에 대한 개선·보완의 의견이 제기되어 왔다. 또한, 유역내 전체하천이 아닌 주요 하천을 대상으로만 치수안전도 설정하여 유역단위의 치수관리에 한계가 있으며, 하천 전체구간의 설계빈도 상향에 따른 홍수방어대책이 비경제적인 것으로 판단된다. 따라서, 기존의 치수안전도의 한계점을 개선하기 위하여 홍수피해잠재능(PFD)의 산정인자 단순화, 홍수위험지도를 활용을 통한 치수단위구역의 공간적 정확도 향상 및 치수단위구역별 설계빈도 조정 가능 등의 개선방안을 검토하였으며, 빈도별 치수단위구역의 홍수피해잠재능(PFD)의 통계적 특성 분석을 통해 등급 설정 및 설계빈도 조정 기준을 제시하였다. 그리고 유역내 전체하천에 대한 치수단위구역별 치수안전도를 설정하고, 중권역 단위의 치수안전도를 평가하여 유역단위의 치수관리 현황을 정량적으로 제시함에 유역 재해안전도로 활용이 가능할 것으로 판단된다.

  • Recently, the patterns of climate change-induced disasters have become more diverse and extensive. To develop an effective flood control plan, Korea has incorporated the concept of Potential Flood Damage (PFD) into the Long-Term Comprehensive Water Resources Plan to assess flood risk. However, concerns regarding the PFD have prompted numerous studies. Previous research primarily focused on modifying and augmenting the PFD index or introducing new indices. This study aims to enhance the existing flood control safety evaluation method by utilizing a flood risk map that incorporates risk indices, specifically focusing on the Yeong-Seomjin river basin. The study introduces three main evaluation approaches: risk and potential analysis, PFD and flood management level analysis, and flood control safety evaluation. The proposed improved evaluation method is expected to be instrumental in evaluating various flood control safety measures and formulating flood control plans.

  • The study attempts to interpret original location and landscape composition of Yowol-pavilion Garden under the premise that tablet and poetry are important criteria for inference of unique location and landscape composition of a pavilion garden. The study raises the meaning, status, and value of Yowol Pavilion Garden as a cultural asset. The results of the study are as follows. First, Yowol-pavilion Garden was a place where famous Confucius scholars in Joseon Dynasty in 16th Century, including Kim, Kyung-Woo, the owner of the garden, used to share the taste for the arts and poetries with their colleagues. Along with a main characteristic of Yowol Pavilion Garden as a hideout for the Confucius scholars who stayed away from a political turmoil, the new place characteristic of the garden, a bridgehead for the formation of regional identity, was discovered in the record of "Joseon-Hwanyeo-Seungram Honam-Eupji JangSeong-Eupji", As described in "The first creative poetry of Yowol-pavilion", the intention for the creation of Yowol-pavilion Garden and the motive for its landscape composition is interpreted as a space of rivalry where the world, reality and ideals are mixed up. Second, related to outstanding scenic factors and natural phenomena when taking a view from the pavilion, the name of the house 'Yowol', which means 'Greeting the moon rising on the Mt. Wolbong' is the provision of nature and taste for the arts, and is directly connected to the image of leaving the worldly. In other words, the name was identified to be the one that reflected the intention for landscape composition to follow the provision of nature separating from joy and sorrow of the mundane world. Third, as for the location, it was confirmed through "YeongGwang-Soksu-Yeoji-Seungram" that Yowol-pavilion Garden was a place where the person who made the pavilion prepared for relaxation after stepping down from a government post, and literature and various poetry show that it was also a place of outstanding scenic where Yellow-dragon River meandered facing Mt. Wolbong. Especially, according to an interview with a keeper, the visual perception frequency of the nightscape of Yowol-pavilion Garden is the highest when viewing by considering the east, the direction of Yellow-dragon River, as Suksigak[normal angle's view], towards Yowel-pavilion from the keeper's house. In addition, he said that the most beautiful landscape with high perception strength is when the moon came up from the left side of Yowol-pavilion, cuts across the Lagerstroemia india heal in front of Yowol-pavilion, and crosses the meridian between Mt. Wolbong peaks facing Yowol-pavilion. Currently, the exposure of Yowol-pavilion Garden is $SE\;141.2^{\circ}$, which is almost facing southeast. It is assumed that the exposure of Yowol-pavilion Garden was determined considering the optimized direction for appreciating the trace of the moon and the intention of securing the visibility as well as topographic conditions. Furthermore, it is presumed that the exposure of Yowol-pavilion Garden was determined so that the moon is reflected on the water of Yellow-dragon River and the moon and its reflection form a symmetry. Fourth, currently, Yowol-pavilion Garden is divided into 'inner garden sphere' composed of Yowol-pavilion, meeting place of the clan and administration building, and 'outer garden sphere' which is inclusive of entrance space, Crape Myrtle Community Garden and Pine Tree Forest in the back. Further, Yowol-pavilion Garden has been deteriorated as the edge was expanded to 'Small lake[Yong-so] and Gardens of aquatic plants sphere' and recently-created 'Yellow-dragon Pavilion and park sphere'. Fifth, at the time it was first made, Yowol-pavilion Garden was borderless gardens consisting of mountains and water taking a method of occupying a specific space of nearby nature centering around pavilion by embracing landscape viewed from the pavilion, but interpreted current complex landscapes are identified to be entirely different from landscapes of the original due to 'Different Changes', 'Fragmentation' and 'Apart piece' in many parts. Lastly, considering that Yowol-pavilion Garden belongs to the Cultural Properties Protection Zone, though not the restoration to the landscapes of the original described in tablet and literature record, at least taking a measure from the aspect of land use for minimizing adverse effect on landscape and visual damage is required.

  • This study examines 31 import and export cargo items handled in each port to investigate which items face the most competition among the ports and how many of them are transited to other ports. The study aims to suggest implications for the future port policy of Incheon Port. It was found that the volume concentration in the Western Coast region from 2005 to 2014 became increasingly decentralized. The decentralization began in earnest in 2009 in particular, and the value was 0.448 in 2014, indicating fierce competition among the regions. According to the static and dynamic positioning analyses results for Incheon Port, Pyeongtaek and Dangjin Port, and Gunsan Port, using BCG Matrix, the static positioning analysis showed that Incheon Port belongs to the 3rd quadrant (Cash Cows), Pyeongtaek and Dangjin Port belongs to the 2nd quadrant (Question Marks), and Gunsan Port belongs to the (Dogs) group. This implies that Incheon Port has maintained its position with large shares compared to those of other ports, despite its low growth rate. However, the market position and growth rate of Incheon Port decreased according to the dynamic positioning analysis results. The shift-share analysis results indicated that the volumes of Incheon Port and Gunsan Port were shifting to Pyeongtaek and Dangjin Port. Moreover, the ratio of absolute growth to potential growth of Incheon Port and Gunsan Port turned out to be significantly lower than that of Pyeongtaek and Dangjin Port, implying that Incheon Port and Gunsan Port are declining as compared to Pyeongtaek Port and Dangjin Port. According to the LQ index analysis results, specialized items from Incheon Port that do not overlap with other ports included the following ten items: meat, fish and crustaceans, bituminous coals, crude oil and petroleum, petroleum-refined products, plastic rubber and products, textiles, nonferrous metal and products, electric machinery, and aircrafts and ships. In particular, it was confirmed that the bulk cargo of Incheon Port was actually shifting to Pyeongtaek and Dangjin Port following the policy of re-establishing port functions.
