The major continental blocks in NE-Asia are the North China Block and the South China Blo, which have collided, starting from the Korean peninsula. The suture zone in NE China between two blocks is well defined from the QinIing-Dabie-Orogenic Belt to the Jiaodong (Sulu) Belt by the geological and geophysical interpretation. The discovery of high pressure metamorphic rocks in the Hongsung area of the Korean peninsula can be used to estimate the suture zone. This indicates that the suture zone in the Jiaodong Belt might be extended to Hongsung area. However, due to the lack of geological and geophysical data over the Yellow sea, the extension of the suture zone to the Korean peninsula across the Yellow Sea is obscure. To find out the tectonic relationship between NE China and the Korean peninsula it is necessary to complete U-ie homogeneous geophysical dataset of NE Asia, which can be provided by satellite observations. The CHAMP lithospheric magnetic field (MF3) and CHAMP-GRACE gravity field, combined with surface measured data, allow a much more accurate in-ference of tectonic structures than previously available. The CHAMP magnetic anomaly map reveals significant magnetic lows in the Yellow Sea near Nanjing and Hongsung, where are characterized by gravity highs on U-ie CHAMP-GRACE gravity anomaly map. To evaluate the depth and location of poten-tial field anomaly causative bodies, the Euler Deconvolution method is implemented. After comparing the two potential field solutions with the simplified geological map containing tectonic lines and the distribution of earthquakes epicenters, it is found that the derived structure boundaries of both are well coincident with the seismic activities as well as with the tectonic lineaments. The interpretation of the CHAMP satellite magnetic and GRACE satellite gravity datasets reveal two tectonic boundaries in U-ie Yellow Sea and the Korean peninsula, indicating U-ie norttiern and southern margins of the suture zone between the North China Block and the South China Block. The former is extended from the Jiaodong Belt in East China to the Imjingang Belt on the Korean peninsula, the later from Nanjing, East China, to Hongsung, the Korean peninsula. The tectonic movement in or near the suture zone might be responsible for the seismic activities in the western region of the Korean Peninsula and the development of the Yellow Sea sedimentary basin.

Sustainable water resource management requires the assessment of hydrological variability in response to climate fluctuations and anthropogenic activities. Determining quantitative estimates of water balance and total basin discharge are of utmost importance to understand the variations within a basin. Hard-to-reach areas with few infrastructures, coupled with lengthy administrative procedures makes in-situ data collection and water management processes very difficult and unreliable. In this study, the hydrological behavior of Lake Chad whose extent, extreme climatic and environmental conditions make it difficult to collect field observations was examined. During a 10 year period [January 2003 to December 2013], dataset from space-borne and global hydrological models observations were analyzed. Terrestial water storage (TWS) data retrieved from Gravity Recovery and Climate Experiment (GRACE), lake level variations from Satellite altimetry, water fluxes and soil moisture from Global Land Data Assimilation System (GLDAS) were used for this study. Furthermore, we combined altimetry lake volume with TWS over the lake drainage basin to estimate groundwater and soil moisture variations. This will be validated with groundwater estimates from WaterGAP Global Hydrology Model (WGHM) outputs. TWS showed similar variation patterns Lake water level as expected. The TWS in the basin area is governed by the lake's surface water. As expected, rainfall from GLDAS precedes GRACE TWS with a phase lag of about 1 month. Estimates of groundwater and soil moisture content volume changes derived by combining altimetric Lake Volume with TWS over the drainage basin are ongoing. Results obtained shall be compared with WaterGap Hydrology Model (WGHM) groundwater estimate outputs.

지구 또는 우주 원격탐사 및 관측에서 진일보한 임무 수행을 위해 위성 편대 비행의 필요성이 점차 부상하고 있다. 편대 비행은 단일 위성으로는 실현하기가 어렵거나 불가능한 과학적인 임무를 수행할 수 있다. 다양한 위성 편대 비행 기술에서 중요한 기술 중에 하나는 편대 위성간의 정밀기선결정 기술이며, 정밀도 검증 기술도 함께 동반되어야 한다. 이 논문에서는 Gravity Recovery and Climate Experiment(GRACE) 위성의 실제 Global Positioning System(GPS) 데이터를 사용하여 GRACE A와 B 두 위성의정밀기선결정을 수행하였다. 그리고 K/Ka-Band Ranging system(KBR) 바이어스 거리측정값으로 일괄처리 및 순차처리 방법을 통해 정밀도를 검증하였다. 제안된 순차처리 방법은 KBR 바이어스를 추정하는 대신에 기산점 차분으로 이를 제거하여 정밀도를 검증하기 때문에 검증자(KBR baised range)가 피검증자(GPS-baseline)와 독립적이고 실시간 정밀도 검증에 적용이 가능하다. 그 결과 일괄처리 검증방법과 유사한 1.5 ~ 3.0 mm의 순차처리 정밀도 검증 결과를 얻었다.

This study examined return policies of the Korean retailers and their differences by retail format. Return policies of 363 retailers including dept stores, discount stores, brand consignment stores, small shops, outlet stores, TV home shopping companies, and internet shopping malls were collected. Acceptance of refund or/and exchange, return grace period, and return requirements or restrictions of each retailer were analyzed. The results showed that most retail formats except small shops and internet shopping malls allowed refund. The seven day return grace period was most common though large retail chains allowed more generous time frames and small shops allowed shorter dates. Restrictions for return varied by retailers and retail formats. Generally retailers followed the guidelines of consumer protection laws. The study discussed implications of return policy analysis.

Superconducting Gravimeters (SG) are the most sensitive instruments for measuring temporal gravity variations. The gravimeter is an integrating sensor therefore the gravity variations caused by different sources must be separated for studying a special effect by applying different models and data analysis methods. The present reduction methods for gravity variations induced by atmosphere and hydrosphere including the ocean and the detection and determination of the most surface gravity effects are shown. Some examples demonstrate the combination of ground (SG) and space techniques especially the combination of SG with GRACE satellite derived temporal gravity variations. Resulting from the performance of the SG and the applied data analysis methods some proposals are made for future SG applications.

In Medieval and Christian history, disputation between Augustine and Pelagius originated from different perspectives regarding the free-will of humans and the grace of God. This debate has continued throughout the Middle-Ages and the Reformation to date. In this regard, the purpose of this article is to investigate the implication of opposition and disputation between Augustine and Pelagius on today's society. Overemphasis on human capacity and free-will leads to humanism, while the arguments supporting the grace of God can encourage evasion of the ethical obligations of humans. Augustine and Pelagius had opposing views on this subject. Pelagius emerged in the Roman Empire, emphasizing the ethical responsibility of humans with free-will. On the other hand, Augustine argued that human nature and free-will had been damaged. With a pessimistic outlook on human capacity, he emphasized the grace of God. Shocked by the self-indulgence and ethical negligence of the Church of Rome which was the center of Christian nations at that time, Pelagius strongly urged Christians of the Roman Church to take moral responsibility. However, the theology of Augustine justified the status quo of the Roman Church while Pelagius focused on the necessity of an ethical life of humans based on free-will. Viewing Pelagius' strict moralism as a humanist view that emphasizes human capacity and action, Augustine showed strong opposition to such a view and instead emphasized God's grace. Pelagius was condemned as a heretic as his belief in free-will did not follow Augustine's Doctrine of Grace. However, Pelagianism penetrated Christian history and still poses a threat to Christianity to date. Societal corruption and depravity is still prevalent in today's society as it was in the time of Pelagius. South Korea for instance is exposed to serious moral corruption and a lack of social responsibility as shown in the sinking of the MV Sewol in April 2014. For those reasons, Christian society emphasizes Christian ethics and requires an honest leader who will set an example of Christian life. In this light, I want to examine the implications of disputation between Augustine and Pelagius on today's society.

The purpose of this study was to investigate the consumer sensibility according to the arrangement and area-ratio of a stripe, and the necktie width. The experimental materials developed for this study were a set of stimuli and necktie sensibility scales. The stimuli were 27 color pictures, in which the necktie width(narrow, medium, wide), stripe arrangement(horizontal, vertical, oblique), and stripe area-ratio(1:1, 1:2, 1:3) were manipulated. The 7-point scale was used for the consumere sensibility. Data were obtained from 270 men and women in their 20s and 30s living in Seoul, Gwangju, Daegu, Jinju, and Changwon on November 2011. For the data analysis, ANOVA and Duncan-test were used by using SPSS program. Results of this study were as follows.; The factors of consumer sensibility according to the arrangement and area-ratio of a stripe, and the necktie width consisted of five dimensions of attractiveness, grace, individuality, ability, and activity. The necktie width showed an independent effect on attractiveness and grace. The stripe arrangement showed an independent effect on attractiveness, grace, individuality, and ability. The stripe area-ratio showed an independent effect on grace. Also, interaction effects of the necktie width and stripe area-ratio on ability were found. The study results are highly expected to be used as valuable sources in plans for necktie products.

The citation analysis is not applied to group measurements but to individual papers finding their impact factors among citation chains which are created by tracing citing-cited relationship between any two papers in data set. The individual impact factor is measured by adding each value derived from citation chain. Each paper's impact factor index is calculated by adding the values of each index by direct citing-cited relationship, and the values of each impact factor made by indirectly influencing to the papers in the citation chain. The research introduces a grace period, in which the system holds the papers not cited by other papers yet, but are expected to be cited within this period. Eventually not cited papers after the grace period would be eliminated by the system. The experiment suggests a reasonable database in which the highly influenced papers are gathered, and could be serviced in stead of buying databases filled with worthless not-cited-papers.
