Suitability for the human body, freedom to move and thermal insulation are important design considerations in military clothing. This study investigates the performance and wearer-satisfaction of the functional inner winter uniform currently used in Korea; it is hoped that our data can inform the development of a future version. Interviews were conducted, in which the participants suggested various improvements. The uniforms were mainly worn for guard duty or as daily attire in cold weather. The participants chose how many layers to wear according to the current situation, rather than sticking to the layering recommended in the manual. Layering choices did not significantly affect combat efficiency but were found to affect wearers' comfort. Wearers' satisfaction was found to depend on the convenience of the clothing, whether it was in the appropriate size, freedom to move and thermal insulation. Also, this study suggests a problem with the current size system, as the analysis of size distribution, across all sizes, the range of current production is insufficient to cover the demand.

This article deals with a sensitive issue on intella-tual freedom in Korean society. In details, the authors introduce the current laws Inhibiting Sree flows of information in korean society, and analyze the fundamental problems including in such laws or sections of tllc laws with various examples. Nso introduced are various efforts by the legal circle and NGOs for the improvement of the current situation, with an analysis of the limitatio and problems in such efforts. Finally, the authors suggest the 'desirable' strategies and methods for correcting or abolishmg the current 'controversial' laws which are serious barriers against free information flows, particularly emphasizing the responsibility of librarians who have to be gatekeepers of knowledge and infonnation in a svcalled information society.

This research comprehended the fundamental cause of elderly nursing home residents' negative feelings of loneliness, depression, fear, and loss of self-usefulness as existential issue, since they already went through loss, death of loved ones, geriatric disease and disability. The purpose of this research is to explore how existentialism and existential psychotherapy theory of Irvin D. Yalom can be applied to nursing home environment design, and to suggest design directions. Based on his framework of human's ultimate interest, death, freedom followed by responsibility, isolation, and meaninglessness, interior design suggestions and applicable spaces were presented. Four cases from Australia, Denmark, Japan and Korea were analyzed according to design suggestions to grasp the current situation and to draw further proposition. The conclusions are as follows. (1)Environment should support nursing home residents to resolve existential issues. (2)Death is the least supported issue on all of the cases. Environmental elements that can induce residents to think and discuss on death, hospice program and space for memorial service is necessary. (3)Regarding to freedom, the environment should support resident's disability to maintain independence as much as possible and residents autonomy and decision should be respected. Single/double rooms, motorized bed, free and safe usage of kitchen and garden are necessary. (4)For isolation, Space and time for meditation should be provided. (5)To find meaning of life, environment should support residents in both physical and cognitive aspect so that they can contribute to others. Space for hobby is necessary for continued creativity and self-realization.

Some polycrystalline ferromagnetic mms are composed of continuously connected nanometer scale islands with random crystallite orientations. The nanometer perturbations of the mm introduce a large number of nearly degenerate local field configurations that are indistiguishable on a macroscopic scale. As a first step, this situation is modelled as a thin ferromagnetic disc coupled by exchange and dipole interactions to a homogeneous ferromagnetic plane, where the disc and plane have different easy axes. The model is solved to find the partial $N\acute{e}el$ domain walls that minimize the magnetic energy. The two solutions give a bistable configuration that, for appropriate geometries, provides an important microsopic ferromagnetic degree of freedom for the mm. These results are used to interpret recent measurements of exchange biased bilayer films.

This article has the purpose of clarifying that Rollo May's existential psychotherapy is based on Kierkegaard's concept of anxiety in philosophical aspects. May makes use of Kierkegaard's concept of anxiety to establish his own existential psychotherapy. May points out that Freud's concept of anxiety is too technical in comparison with Kierkegaard's concept of anxiety. Freudian theory accepting anxiety as the cause of repression overlooks the importance of human relationship which brings about repression. May mentions the presence or absence of object to distinguish fear and anxiety. Kierkegaard and Freud also mention that the presence of object is called fear and the absence of object is anxiety. May interprets anxiety ontologically. Succeeding Kierkegaard's comment on nothing/non-being, May insists that anxiety is the experience of Being affirming itself against Nonbeing. May interprets Kierkegaard's concept of freedom as the possibility or potentiality in terms of similar meaning. May argues that Anxiety is the situation when faced with the problem which human being will achieve his potentiality. Kierkegaard's concept of freedom is also associated with sin at the same time as the freedom associated with anxiety. Succeeding this, May discusses the relation of guilt feeling and anxiety is the flipside of the coin. He understands that guilt feeling is not a pathological symptom but an evidence of the human being's possibility. Kierkegaard's The Concept of Anxiety has a sub-title which is 'a simple psychologically orienting deliberation on the dogmatic issue of hereditary sin'. This shows that he understood the relationship between anxiety and guilt as dilemma that can not be separated. Through this study, I want to clarify that May's concept of anxiety which is the most important concept in his existential psychotherapy, is derived from Kierkegaard's concept of anxiety.

In this paper the structure of 2-DOF controller based on artificial immune network algorithms has been suggested for nonlinear system. Up to present time, a number of structures of the 2-DOF controllers are considered as 2-DOF (2-Degrees Of Freedom) control functions. However, a general view is provided that they are the special cases of either the state feedback or the modification of PID controllers. On the other hand, the immune network system possesses a self organizing and distributed memory, also it has an adaptive function by feed back law to its external environment and allows a PDP (parallel distributed processing) network to complete patterns against the environmental situation, since antibody recognizes specific antigens which are the foreign substances that invade living creatures. Therefore, it can provide optimal solution to external environment. Simulation results by immune based 2-DOF controller reveal that immune algorithm is an effective approach to search for 2-DOF controller.

It is well known in a small sample that the maximum likelihood (ML) approach for variance components in the general linear model yields estimates that are biased downward. The ML estimate of residual variance tends to be downwardly biased. The underestimation of residual variance, which has implications for the estimation of marginal effects and asymptotic standard error of estimates, seems to be more serious in some limited dependent variable models, as shown by some researchers. An alternative frequentist's approach may be restricted or residual maximum likelihood (REML), which accounts for the loss in degrees of freedom and gives an unbiased estimate of residual variance. In this situation, the REML estimator is derived in a censored regression model. A small sample the REML is shown to provide proper inference on regression coefficients.

Complex dynamic systems are composed of several subsystems. Each subsystems affect the dynamics of other subsystems since they are connected to each other in the whole system. Theoretically, we can derive the exact mass and stiffness matrix of a system if we have the natural frequencies and mode shapes of that system. In real situation, the modal parameters for the higher modes are not available and the number of degree of freedom concerned are not so high. This paper shows a simple method to derive the mass and stiffness matrix of a system considering the connecting points of subsystems. Since the accuracy of reconstructed structure depends on the selection of node and mode, the rule for selection of node and mode are derived from the numerical examples.
