In assessing risks related to working posture, pictures of postures are taken from various directions, which can be a source of observation error. Joint postures of the neck, lower back, knee, shoulder, and elbow were taken from 7 different viewing angles and 19 observers estimated joint angles by observing the pictures in 2-dimensional display. The joint angles were also measured using an optoelectronic motion measurement system. The estimation error increased as the viewing angle varies from the right side of the human body, but the patterns differ according to which joint angles were being observed. Guidelines to increase the validity of observation of joint angles were presented based on the results. In general, it is recommended to maintain the viewing angle within 20 degrees from the right side of the human body, while different ranges of viewing angle are recommended for each joint angle.

Human Resource Management (HRM) performs numerous activities in organizations including employee recruitment, selection, placement, job analysis, training and development, and labor relations. POSCO (Pohang Steel Company) has concerned with employee management related to job placement and analysis among these activities because of the problems of over-complexity of placement precedures for the variety of recruits, the frequency of selection, a large amount of job descriptions / specifications, and their changes. This study, as a phase of developing the entire HRM systems in the organization, briefly summarizes the preliminary information related and describes an implementation of expert system as a means for effective job placement based on the principle of right-person-in-right-place with identifying aptitudes and personalities of employees. Thus, a new approach for developing a job description/specification using a formal specification language like Z is also proposed. The result of this study will cultivate the performance of personnel, prevent conflicts between labor and management, promote overall productivity of organization, as well as helpfully verify job analysis.

In the smart intelligence information society, there is a possibility that the social dysfunction such as the personal information protection issue and the risk to the electronic surveillance society may be highlighted. In this paper, we refer to various categories and classify electronic surveillance into audio surveillance, visual surveillance, location surveillance, biometric information surveillance, and data surveillance. In order to respond to new electronic surveillance in the intelligent information society, it requires a change of perception that is different from that of the past. This starts with the importance of digital privacy and results in the right to self-determination of personal information. Therefore, in order to preemptively respond to the dysfunctions that may arise in the intelligent information society, it is necessary to further raise the awareness of the civil society to protect information human rights.

Food sovereignty is the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems. An increase in the price of food that occurs as a result of increased demand from human consumption and use as an alternative energy resource. Furthermore, agflation, a combination of the words "agriculture" and "inflation", will also affect non-vegetative foods as the price increases for grain will make livestock feed more expensive as well. Food sovereignty implies new social relations free of oppression and inequality between men and women, peoples, racial groups, social classes and generations.

In this paper, wireless interface of the motion between human and robot is implemented. The idea is that if a human who is equiped with device including accelerometer and rate-gyro sensor move his/her arm, then the robot follows human motion. The robot is designed as wheeled type mobile robot with two link arms. The robot´s basic movements such as forward, backward, left, right movement can be controlled from foot sensor which human steps on. Arm movements can be controlled by arm motion of human motion. In order to detect human motion, sensor data analysis from gyro and accelerometer has to be done. Data from sensors are transferred through wireless communication to activate the robot.

정보사회의 도래로 인해 정보의 효율적인 사용과 어느 곳에서든지 필요한 정보를 상시 사용 가능하다는 긍정적인 면도 있지만 개인정보의 보호문제라는 새로운 과제가 발생하였다. 지난 20년간 법학계에서는 이러한 문제를 해결하고 개인정보를 보호하기 위한 정보인권의 연구가 활발하게 진행되었는데, 이에 관해서는 매우 다양한 관점과 이론이 제시되었다. 정보인권은 우선 개인정보시스템의 안정성에 관한 인권, 인격권, 자기정보통제권, 정보접근권, 알 권리로 유형화할 수 있다. 본 연구는 정보인권에 관한 과거의 연구들을 분석하여 정보인권을 유형화하고, 지난 연구들의 시대적 특성과 흐름을 알아보고자 한다. 이러한 연구를 위해 지난 연구논문들과 학위논문 등 200개의 성과물을 분석하였고, 이를 통해 체계 있는 정보인권연구를 위한 방향을 제시하고자 한다. 이를 통해 본 연구는 향후 정보인권에 관한 보다 실효적인 연구에 도움이 될 것이다.

가정은 가장 기초적인 사회집단으로서 가정이 개인에게 미치는 영향은 매우 크다. 우리사회에서는 가정폭력(家庭暴力)에 대한 사회적 관심이 높아지고 있다. 가정폭력은 사회의 폭력성을 반영할 뿐만 아니라 자녀들에게 폭력을 가르치는 폭력학습의 장이 되고 있다는 주장이 제기되면서 가정폭력이 개인 문제가 아니라 사회문제라는 인식을 가지게 되었다. 본 논문에서는 가정폭력은 가해자나 피해자나 결국 모든 문제가 '인권'(人權)의 문제로 귀결된다는 관점에서 첫째, 우리 사회에서 발생하고 있는 가정폭력의 실태를 파악해 본다. 둘째, 가정폭력의 원인을 밝혀본다. 셋째, 가정폭력에 관한 법률의 주요 내용과 문제점들을 검토해 보고 그 개선방안을 제시해 보고자 한다.

불심검문이란 경찰법상 경찰목적을 이루기 위하여 피검문자 개인의 의지여부와는 상관없이 그로부터 정보획득 또는 신원확인을 위한 경찰조치이다. 하지만 창과 방패처럼 불심검문은 공권력과 인권의 접점에서 양면성을 가지고 태어난 태생적 한계로 인하여, 오래 동안 우리사회에서 뜨거운 감자가 되어 왔다. 불심검문의 논점의 핵심은 불심검문을 하기 위한 제1조치인 경찰관의 정지요구에 피검문자가 불응할 경우에 경찰관이 유형력을 행사하여 피검문자를 강제로 정지시킬 수 있는가에 있다. 경찰관의 유형력행사의 한계에 관한 문제이다. 불심검문이 범죄예방과 범인검거면에서 어느 정도 효과가 있다는 평가도 있지만, 과거 경찰의 마구잡이식 불심검문의 기억으로 인하여 국민들은 지금도 이에 대한 불쾌감과 거부감을 가지고 있다. 이러한 의미에서 경찰은 불심검문에 관한 대국민신뢰를 회복할 필요가 있다. 이를 위해서는 불심검문시 범죄예방 및 범인검거보다 국민의 인권을 우선시 하여야 한다. 이것은 시대적 당위이다. 불심검문시 경찰관의 정지요구에 불응하는 피검문자에게 경찰관의 유형력행사는 엄격한 요건 하에 행해져야 한다.

This paper deals with human spatial cognition using visual and auditory stimulation. More specially, this investigation is to observe the relationship between the head and the eye motor system for the localization of visual target direction in space and to try to describe what is the role of right-side versus left-side pinna. In the experiment of visual stimulation, nineteen red LEDs (Luminescent Diodes, Brightness: $210\;cd/^2$) arrayed in the horizontal plane of the surrounding panel are used. Here the LEDs are located 10 degrees apart from each other. Physiological parameters such as EOG (Electro-Oculography), head movement, and their synergic control are measured by BIOPAC system and 3SPACE FASTRAK. In the experiment of auditory stimulation, one side of the pinna function was distorted intentionally by inserting a short tube in the ear canal. The localization error caused by right and left side pinna distortion was investigated as well. Since a laser pointer showed much less error (0.5%) in localizing target position than FASTRAK (30%) that has been generally used, a laser pointer was used for the pointing task. It was found that harmonic components were not essential for auditory target localization. However, non-harmonic nearby frequency components was found to be more important in localizing the target direction of sound. We have found that the right pinna carries out one of the most important functions in localizing target direction and pure tone with only one frequency component is confusing to be localized. It was also found that the latency time is shorter in self moved tracking (SMT) than eye alone tracking (EAT) and eye hand tracking (EHT). These results can be used in further study on the characterization of human spatial cognition.

The purpose of this study was to develop the construction process of orthopedic compression garments (OCG) for balancing of the left and right lumbar muscle power and strength to prevent low back pain. One male subject having low back pain was involved for investigating of the lumbar muscle power. EMG (Telemyo DTS2, Noraxon, U.S.A) was measured with/ without 3 types of waist assistant belt around the waist area of the subject. Based on the electromyogram value of left and right body, OCG were constructed as follows. Firstly, stretchable t-shirts type with supportive waist belt was selected for the convenience of wearing and laundering the OCG. The design lines of the front and back waist parts were created depending on the anatomy of the torso. Secondly, 3D pattern was developed using 3D Clo, RapidForm XOR, 2C-AN, and Yuka CAD program to increase the fit of the OCG. Finally, stretchable power-net was layered as linings in two ways, a single lining and double layered linings, and evaluated measuring lumbar muscle EMG by five subjects with low back pain. As the results, they were effective to balance the left and right lumbar muscle power and strength. Also the OCG with the double layered power-net lining was superior to the one layered lining in terms of fit and comfort.
