This article reviews recent developments in three-dimensional (3-D) magntotelluric (MT) imaging. The inversion of MT data is fundamentally ill-posed, and therefore the resultant solution is non-unique. A regularizing scheme must be involved to reduce the non-uniqueness while retaining certain a priori information in the solution. The standard approach to nonlinear inversion in geophysis has been the Gauss-Newton method, which solves a sequence of linearized inverse problems. When running to convergence, the algorithm minimizes an objective function over the space of models and in the sense produces an optimal solution of the inverse problem. The general usefulness of iterative, linearized inversion algorithms, however is greatly limited in 3-D MT applications by the requirement of computing the Jacobian(partial derivative, sensitivity) matrix of the forward problem. The difficulty may be relaxed using conjugate gradients(CG) methods. A linear CG technique is used to solve each step of Gauss-Newton iterations incompletely, while the method of nonlinear CG is applied directly to the minimization of the objective function. These CG techniques replace computation of jacobian matrix and solution of a large linear system with computations equivalent to only three forward problems per inversion iteration. Consequently, the algorithms are efficient in computational speed and memory requirement, making 3-D inversion feasible.

Exposure and Concealment have been continued as important way to express fashion and theme as well, especially in women fashion. Exposure can make themselves attractive, and concealment emphasizes this way of being attractive by exposure. Besides the temptable effect of exposure, the ideology which put women next men in society has made a prominence on the fact exposure is significant theme in women fashion. It means that women's image of 'Being seen as Object' (this can be explained by relation passive between active) in society has driven female emphasize in using and focusing on exposure to be attractive. Also the other important thing in women fashion has been considered is concealment. The fact that society has demand women more chaste duty in detail may have meaningful thing in the condition that instigates women take off being attractive to the subject, considering ideology, men. Therefore attractive femininity has to be suggested by virtue and temptation, it is common sense that looking just shallow or too strict are far from criteria of ideal beauty. Namely, the concept for exposure coexists with concealment not only constructively but also naturally in fashion. Technique that can be accentuate for effective exposure differently from method to show unilaterally is needed, and this technique can promote new fashion. And according to the theory of Freud, women means' Absence (lacking penis)', this female's Lack Image induces male castration complex therefore 'Fetishistic Look' which transfers something phallic into specific things or parts of body is adopted, sort of object cathexis. This is revealed as some parts of women body are diverted into object for sexual love, symbolic equivalent. For example, women's parts like legs or breast are remarked as erotogenic zone and as time goes, when no more the zone are felt sexual by exposure, other somewhere felt mysterious (felt something sexual) used to be stressed by exposing. As it were, it can be possible that exposing part on women body (sexual part) moved as time passed because of what previously stated. Especially, the concept of exposure and concealment in women fashion should explain not only from a point of view of style for the beautifulness but also from wearer's immanent intention, further more relationship with ideology. About the present situation becoming bolder in women fashion, it is said that women express confidence as the position of women is elevated higher socially, the more women get freedom. But if we consider this psychoanalysis opinion mentioned ahead, the possibility can not be excluded that the exposure can get emphasizing according as the need of feminine modesty gets decreasing from ideal femininity society, men want. This study about exposure and concealment was made progressed through the theory of Freud who originated psychoanalysis, presented many theories. But nowadays contradictions are being brought up against Freud's theory including conventional philosophy like male chauvinism and adjust studies get suggested. Hereupon, there may be limitation in making no allowance of contradiction and following his theory.

By implementing epoch-making policies for industrial promotion, the national economy has made a remarkable development. As a result of such economic growth, industrial accidents and occupational diseases have become a serious problem in Korean society. In the presidential order for the execution of the Korean Labor Standard Law, neuritis and other diseases stemming from health impairments due to vibrations in industrial processes are designated to be dealt with as vibration diseases. In the case of vibration disease, industrial accident compensation is not effectively paid. In order to investigate the vibration hazards of rock-drill operation, the authors studied the subjective symptoms and performed physical function tests on a total of 79 persons (vibration exposed group) who used rock-drills, and 39 persons (control group) who did not use rock-drills at anthracite mines. The results of the physical function test were as follosws : 1. The right hand was more affected by white finger than the left hand. 2. Independent variables such as duration of rock-drill operation, age, drinking and smoking were indentified as statistically significant factors for the occurrence of white finger. 3. In the pain sense threshold, the group with Raynaud's phenomenon showed a statistically higher level than that of the control group. 4. The skin temperature of the group with Raynaud's phenomenon was lower than that of the control group. The recovery time of skin temperature aftr cooling was delayed compared with the value of the control group.

This study is about the phenomenological study of bodyguards' ethical dilemmas. Through this study, the meaning and essence of bodyguards' ethical dilemmas will be analyzed based on empirical facts. The purpose of this study is to provide basic information of the prevention and solutions for their ethical dilemmas and to understand and research the process and the essentials of them. To achieve this goal of the study, seven bodyguards who experienced ethical dilemmas working more than five years are selected as objects of the study. Colaizzi's six stage method are applied into this study so information gathered through interviews and questionnaire from 0ctober 1st, 2015 to November 20th, 2015 is analyzed. From the process of this research, these following conclusions are drawn considering validity of this study and ethical things. As a result, bodyguards' ethical dilemmas are divided into six centric meanings and 20 thematic statement. First, the centric meaning is conflict factors and the themes are discordance of pre-practice, regulatory or procedure problems, communication about sturcture and job and service disagreement. Second, the centric meaning is limited professional roles and the themes are institutional custom, decision making, priorities. Third, the centric meaning is difficulties of circumstantial judgement at work places and the themes are ambiguity of decision, conflict of knowledge, experience and opinion. Forth, the centric meaning is reasonable self-defense and the themes are lack of responsibility, rationalization, intentional negligence and sense of shame. Fifth, the centric meaning is difficulties of social network and the themes are the relationships between subordinates and superiors, the role of a moderator, uncooperative work and unpleasant sayings and doings. Sixth, the centric meaning is keeping secrets and the themes are burried for and illegal practice.

Filming using multiple cameras is required for the production of the multi-screen content. It can fill the viewer's field of view (FOV) entirely to provide an increased sense of immersion. In such a filming scenario, it is very important to monitor how images captured by multiple cameras are displayed as a single content or how the content will be displayed in an actual theatre. Most recent studies on creating the content of special format have been focused on their own purposes, such as stereoscopic and panoramic images. There is no research on content creation optimized for theatres that use three screens that are spreading recently. In this paper, we propose a novel content production system with a rig that can control three cameras and monitoring software specialized for multi-screen content. The proposed rig can precisely control the angles between the cameras and capture wide angle of view with three cameras. It works with monitoring software via remote communication. The monitoring software automatically aligned the content in real time, and the alignment of the content is updated according to the angle of camera rig. Futher, the producion efficiency is greatly improved by making the alignment information available for post-production.

The purpose of the study you have seen is to verify the effectiveness of existing quantitative research and to put the Empathy Training Program to practical use for participating children. From looking into this, the changes in empathic understanding that came to light in relationships between teacher and children and children and children are sure to have that effect. For this work, I established the following subject of inquiry: What kind of changing processes can be seen in the empathic understanding of participating children in the Empathy Training Program? To resolve the above line of inquiry, six female sixth grade elementary school students were chosen and they progressed through twelve sessions of the Empathy Training Program. The children were given a sentence completion exam, recognition work, neat writing exam and a school adaptation exam both before and after participation in the program, making data for analysis. To analyze, first, participants had one or two meetings of forty to fifty minutes each. Progress through the program's curriculum was recorded and through the repeating and copying method, to be sure participating children's empathic understanding was revealed, empathic language and behavior was routinely chosen. Next, according the above criteria I looked into visible changes of the participating children's empathic expressions, classifying and analyzing changes in empathic understanding and six instances of common changes in the emphatic understanding of the participants relationships were analyzed and put together. Next I will summarize the findings we have seen in this research: First, if we look into changes in common empathic understanding from the beginning, using the criteria of empathic language, each individual showed understanding at the beginning and passed and progressed through stages of care, insight and emotional expressions. Second, when we looked at the criteria of empathic behavior from the beginning to the end, one's line of vision and ability to concentrate one's attention was connected. Next, the act of nodding one's head looked like a brief nod at first but at the end, it was not just a simple nod but rather they could feel deep empathy. The condition and substance of the facial expression was seen to match and at the very end the child was expressive and stretched out arms to hold and pat the other person and the act of holding hands could also be seen. Among lots of empathic behavior the final stage was shown by half of the children. Third, from the first stage to the last stage there were many cases revealed. The more the children went the more complete their empathic language became. Their vocabulary increased and became more diverse with empathic actions. Also, when comparing actions and expressions from the beginning with the end, visible expressions became more natural and sincere at the end. The result of the research we have seen is that through receiving experience of empathic understanding, participating children showed a sense of self-confidence and they looked to make peaceful expressions while not being aggressive or defensive about problems. In addition, from understanding empathic expressions, participating children's relationships felt closer. This outcome within this group in this case will be applied and the formation of empathic understanding can be used by the children internally to solve their own problems, acquire close relationships with their teachers and others. It will also contribute to smooth classroom management.

The purposes of this study were to develop analysis criteria and analyze the two subject competencies of units dealing with the core concept 'Relation' of the middle school Technology-Home Economics textbook in accordance with the 2015 revised curriculum: 'practical-problem-solving-ability' and 'relationship ability'. The subject of analysis of the current study was the activity assignment of Chapter 1 related to the core concept 'Relation', from the twelve middle school 'Technology-Home Economics II' textbooks. The results of this study were as follows: First, some textbooks showed differences in highlighting or downplaying the components of certain subject competencies. The analysis results for 'practical-problem-solving-ability' in textbook A, E, and G were shown in the high frequency, while in textbook D in the lowest frequency. The analysis results for 'relationship ability' in textbook K and A were shown in the high frequency, while in textbook J in the lowest frequency. Second, Value Judgement was the most frequent component of 'practical-problem-solving-ability' followed by Logical Thinking, Practical Reasoning, and Decision-Making. Family Relation and Sense of Community was the component of 'relationship ability' most frequently dealt with followed by Communication, Conflict Management, and Respecting Others, however Environmental and Ecological Awareness was not shown at all. The two subject competencies were mostly reflected in the Technology-Home Economics textbooks from all the twelve publishers.

The objective of this study was to examine the possibility of utilizing the immersion stereoscopic image with a curved-screen-display as a tool for evaluating the landscape. The curved-screen-display ensures the continuity of the image and can be simultaneously evaluated by many people. Fifty-meter-wide Gangnamdaero Boulevard in Seoul was selected for this study, and the simulation was done using computer graphics. With the computer simulation, a questionnaire on landscape preferences was conducted according to different visual environments (immersion, non-immersion) and different projection types(stereoscopic or plane image). In the results of this study, the landscape preference was largely dependent on the immersion environment. Using the immersion-type simulation, the observer can easily evaluate the preference with higher judgment power. The stereoscope or plane projection type does not have any significant result in terms of its judgment power. This result implies that it is very important to strengthen the sense of immersion by expanding the screen into an angled view in which the observer can become immersed while making and projecting the simulation to evaluate the landscape. As a landscape evaluation tool for examining the efficiency and usefulness of immersion simulation, this study has limitations in that it controls many factors in street landscape that adversely affect judgment. Accordingly, a detailed comparison and verification of the stereoscopic image in various environments, including street width and building height ratio, must be conducted.

It is necessary for inmates released from prison to recover their career capital in order to function normally in society. Failure to adapt to the society may not only make them unhappy but could also aggravate social safety nets. Therefore, it is critical to examine the recovery of career capital. For this study, we conducted in-depth interviews of 10 rehabilitation recipients who were supported by Korea Rehabilitation Agency. For qualitative analysis, several career topics were analyzed, such as obstacles in recovering career capital, efforts in overcoming these obstacles, what is helpful for them to overcome the obstacles and what is required for them to adapt to the career life and others. Analysis results found that the rehabilitation beneficiaries suffered loses to their career capital due to their incarceration, suffered from the loss of pride and became despondent in the process of recovery of career capital due to the negative social perception toward their social self, fear of social stigma and devaluation of themselves. In addition, the fear of possible negative evaluation was a critical factor in making their social activities more challenging. Conversely, it was found that social support in the recovery process of career capital has a positive effect. In particular, emotional support from spouses, employers, family members and friends are the most positive factors. Concerning efforts at adapting to careers, it was found that an active, leading and positive attitude toward the career were critical, showing that positive evaluation and recognition in family and social relations and the experience of success in the career were positive elements in enhancing a sense of pride. In summary, it was found that in the recovery process of career capital, dysfunctional beliefs had a negative effect, while social support had a positive effect, on the recovery of career capital.
