Ecological concepts were embedded in the old Korean maps and other documents. The concepts may represent ecological views which people had at the time. Through those ecological views, we propose that we can see a watershed concept in old Korean maps. We also discuss relevant records to understand the history of this concept. While many scholars have highlighted in the Baekdoodaegan frame only the pan of the mountain ranges, we are pointing out other perspectives. Our emphasis is that the concept is explicitly related to a watershed concept. An old Korean map shows that people at that time divided the Korean Peninsula into many watersheds, which was as early as 1402. We can even say that the idea is identified in a literal document written in the 12th century. It is hypothesized that a typical Korean landscape configuration was developed in the arrangement of village and surrounding landscape elements situated in a watershed. In addition, we suggest that the view had some negative effects on the current society. Even though the ideas of our ancestor are something to be praised, further study is needed to improve it in a wise manner.

Purpose: The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was designed to measure post-traumatic symptoms related to childbirth and symptoms during postnatal period. The purpose of this study was to develop a translated Korean version of the PPQ and to evaluate reliability and validity of the Korean PPQ. Methods: Participants were 196 mothers at one to 18 months after giving childbirth and data were collected through e-mails. The PPQ was translated into Korean using translation guideline from World Health Organization. For this study Cronbach's alpha and split-half reliability were used to evaluate the reliability of the PPQ. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group validity were conducted to examine construct validity. Correlations of the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory (BAI) were used to test a criterion validity of the PPQ. Results: Cronbach's alpha and Spearman-Brown split-half correlation coefficient were 0.91 and 0.77, respectively. EFA identified a 3-factor solution including arousal, avoidance, and intrusion factors and CFA revealed the strongest support for the 3-factor model. The correlations of the PPQ with IES, BDI-II, and BAI were .99, .60, and .72, respectively, pointing to criterion validity of a high level. Conclusion: The Korean version PPQ is a useful tool for screening and assessing mothers' experiencing emotional distress related to child birth and during the postnatal period. The PPQ also reflects Post Traumatic Stress Disorder's diagnostic standards well.

Due to recently advanced electrical devices, human can access computer network regardless of working location or time restriction. However, currently widely used mouse, joystick, and trackball input system are not easy to carry and they bound user hands exclusively within working space. Those make user inconvenient in Ubiquitous environments.. In this paper, we propose multiple dimension human motion detection system based on wireless sensor networks. It is a portable input device and provides easy installation process and unbinds user hands during input processing stages. Our implemented system is comprised of three components. One is input unit that senses user motions and transmits collected data to receiver. Second is receiver that conveys the received data to application, which runs on server computer. Third is application that performs command operations according to received data. Experiments shows that proposed system accurately detect the characteristics of user arm motions and fully support corresponding input requests.

In 3D video compression, a disparity vector (DV) pointing a corresponding block position in an adjacent view is a key coding tool to exploit statistical correlation in multi-view videos. In this paper, neighboring block-based disparity vector (NBDV) is shown with detail algorithm descriptions and coding performance analysis. The proposed method derives a DV from disparity motion vector information, obtained from spatially and temporally neighboring blocks, and provides a significant coding gain about 20% BD-rate saving in a texture-video-first-coding scheme. The proposed DV derivation method is adopted into the recent 3D video coding standards such as 3D-AVC and 3D-HEVC as the state-of-the-art DV derivation method.

With the increase of double-income families, parents are not free in terms of time and space in communicating with teachers. Also for teachers, with many students and heavy load of work, communication with parents has been poor. As a means for overcoming this kind of situation, this research examined the current status of communication between teachers and parents using SMS and problems to solve. The investigation of the actual conditions of SMS use showed that there was a high number of answers pointing out that SMS is needed for the exchange of information regarding children and educational activities, and teachers pointed out that the communication was effective for exchanging educational information regarding children whereas parents pointed out that it was effective in improving the children's attitudes. Based on the results of the analysis, the following was found as tasks to be solved: preparing a plan for revitalizing SMS use, solving the burden that parents have in communicating with teachers, becoming more friendly with teachers, investigation of the reason why there is no response regarding SMS and preparing countermeasures, providing information appropriate to what parents want, increasing the reply rate of parents, expansion of text capacity, and trouble with getting online with a computer.

In the Japanese colonial period of Korean history, appropriate conclusion often overwhelmed the historical imagination, and also pointed out that it shows a similar pattern in spite of the history detective novel genre that emerged with pointing out the limitations of modern history. Historical facts showing in , the legitimacy of independence based on nationalism, and modern civilization are well known in the historical and cultural contents of the Japanese colonial period. It is the reason why applied in historical and cultural contents, as the history as is for current desire of the public to the imaginary community(nation), and as the history which current social conflicts are reflected. History, historical facts and fiction are intermingled in the contents of history, and it is creating a new 'historical imagination'. As a matter of fact, there is only one fact of the past, but the historical imagination of historical and cultural contents is diverse as there is not one historical fact made by historians. History has not yet gone to the imagination for the future, but writing history through historical and cultural contents will create a 'history of possibilities'.

Objective: The purpose of this study was to compare the activities of the abdominal muscles according to trunk stabilization exercises using Swiss ball in normal individuals. Design: Cross-sectional study. Methods: Ten healthy university students participated in this study. The subjects were required to complete the following three exercise positions: Exercise position 1, sitting on a Swiss ball and lifting the legs; Exercise position 2, pushing to a plank position from an ending position; and Exercise position 3, push-up posture with the legs on a Swiss ball. Changes in the trunk muscle activities were estimated using Biometric electromyography (EMG). Activities of the dominant side internal oblique muscle (IOM) and external oblique muscle (EOM) were estimated in all participants. The maximal voluntary isometric contraction (MVIC %) was measured to standardize the EMG signals for the IOM and EOM during maximum resistance when sitting up with each shoulder pointing towards the contralateral pelvis with knees bent and both arms crossed on the chest for 5 seconds. Results: There was a significant difference in the activity of the internal and external oblique muscles between Exercises 1 and 2 and Exercises 1 and 3 (p<0.05). Furthermore, the IOM/EOM activity ratio was the greatest during Exercise 3 and the smallest during Exercise 1. IOM and EOM activities were the greatest during Exercise 2 with greater EOM activity. Conclusions: In future studies, it will be necessary to investigate muscle activities by supplementing the above-mentioned limitations during the stabilization exercise. The results of this study may be used as a basis for controlling the intensity and frequency of exercise while prescribing trunk stabilization exercises.
