It was required Integrated Network Management Architecture(INMA) with consistency and standardization in order to support efficiently communication service for operators and users. In such ITU-T(International Telecommunication Union - Telecommunication) recommended TMN(Telecommunication Management Network) which is Network management architecture for telecommunication, and intended to achieve uniform and comprehensive network management using standardized network management interface. This paper proposes C31 management services and management functions based on ITU-T and RACE project. This designs C31 INMA based on TMN concept in order to manage efficiently C31 communication network. The C31 INMA supports to manage C31 LAN and WAN devices and lines with global and correspondence, and helps Integrated Network Management system design and implementation.

Recently a supercavitating underwater vehicle moving at high speed over 200 knots has been of interest for its practical advantage of the dramatic drag reduction. Many experimental and numerical studies have been explored, however most of the studies deal with the case of uniform flows. In this paper, we investigated physical behaviors of the artificial supercavity in a periodic gust flow. Experiments were carried out at a cavitation tunnel of the Chungnam National University(CNUCT), which is equipped to remove the gas supplied from outside of the tunnel. We devised an experimental apparatus generating vertical and horizontal gust flows, and investigated the supercavity formations at different periodic mode of the incoming flow.

The microstructure evolution during a hot forging of Waspaloy was investigated using the recrystallization model and FEM simulation. In order to obtain an uniform microstructure, hot forging was carried out by two step. The change of grain size during hot forging has a deep connection with dynamic recrystallization behavior. Avrami-type constitutive equation for the dynamic recrystallization was implemented into an user subroutine of 2D FE simulator. The evolution of grain structure in the two-step forging of Waspaloy was simulated using the 2D FEM user-subroutine. The detailed variation of microstructures due to dynamic recrystallization could effectively be predicted at various locations in a forged pancake.

For the development of reliable thermal batteries, electrolyte is quite important because it is closely related to the performance and stability of thermal batteries. This paper describes general image processing method used for the inspection of molten-salt based electrolyte disk and also describes how we can apply this image processing method to the inspection of thermal battery electrolyte. Moreover we have found optimized image processing conditions to improve the discriminating ability of compaction defects such as non-uniform parts in an electrolyte.

A high power laser beam focused on a small area accelerates a thin material that flies and hits other target material in which a shock wave may be induced. This laser induced shock experimental method is more repeatable and cheaper but worse than other experimental method using gas gun or other apparatus. An optical system including a phase zone plate reduces the interference and also makes the focused-beam-intensity distribution uniform. We wrote a computer code that calculates light ray traces. Using the code we designed and fabricated an optical system including a phase zone plate and improved the laser-beam uniformity. We introduce preliminary experimental results of laser induced shock of the samples such as aluminum and other materials.

Currently, soldiers enlisted in the military (Army) are receiving measurements (automatic, manual) of body parts and trying on sample clothing at boot training centers, and then receiving clothing in the desired size. Due to the low accuracy of the measured size during the measurement process, in the military, which uses a relatively more detailed sizing system than civilian casual clothes, the supplied clothes do not fit properly, so the frequency of changing the clothes is very frequent. In addition, there is a problem in that inventory is managed inefficiently by applying the measurement system based on the old generation body shape data collected more than a decade ago without reflecting the western-changed body type change of the MZ generation. That is, military uniforms of the necessary size are insufficient, and many unnecessary-sized military uniforms are in stock. Therefore, in order to reduce the frequency of clothing replacement and improve the efficiency of stock management, deep learning-based automatic measurement of body size, big data analysis, and machine learning-based "Personalized Combat Uniform Automatic Recommendation System for Enlisted Soldiers" is proposed.

This study is to analyze the symbolic images appeared in modern fashion design adopted dualistic meanings in uniforms. Uniforms signify order, conformity and discipline in public life. The dualistic meanings in uniforms appeared modern times are as follows: public authority vs individual non-authority, heterosexual identity vs homosexual identity, time-space uniformity vs mixed diversity. The symbolic images appeared in modern fashion design adopted dualistic meanings in uniforms such as military uniforms, school uniforms, nurses' uniforms, sports uniforms and etc. are erotic image, hybrid image, and kitsch image.

A Politician Appearance Acceptance Model (PAAM model) was formed and designed based on an analysis of how the electorate would accept a female politician. The PAAM model evaluated factors which influenced the voter's view of the female politician based on appearance. Causative factors were assessed that impacted acceptance based on appearance and analyzed whether voting was influenced by the appearance image; appearance image preferences for a female politician included the classic, dramatic, romantic and natural images. Through validations, the appearance image and competency had a causative factor that contributed to the acceptance of the politician image. The Classic Image demonstrated the strongest and most important image among the appearance images. As voters were more interested in the appearance image of a female politician, more emphasis and weight was on the appearance image during the voting selection process.

A general solution for temperature distribution And heat transfer for a uniform straight fin is yen. Thermal conductivity and heat transfer coefficient between the fin and the surrounding fluid can be arbitrary functions of temperature. Minimum weight conditions for a rectangular fin are analyzed, Numerical results for some special cases are given in graphical forms.

Clothing as one of elements of culture has been interwoven with cultural diffusion, and accompanied the most visible change. In this paper, it was focused that the process and the characteristics of western clothing adop-tion of Korea from 1876 to 1945 corelating with cultural diffusion theory. They were analyzed through the change of clothing reformation system by government, school uniform, and social phenomenon. The finding of this paper were as followings; 1. The process of western clothing adoption was forcibly demanded by Japan, therefore influenced by Japan. 2. The clothing reformation which was forced to accept western style was confronted by complex of cultural, psychological and economical resistance. 3. The fashion leaders of this period were Korean students studying abroad, diplomatic officials, members of the armed forces, government officials, students of western educational systemed school, and lady of evangelist. 4. Man adopted western clothing earlier than woman. 5. Western clothing adoption was took precedence in case of formal wear, diplomatic official's attire, military uniform, and school uniform. 6. In this process, we can find 'transculturation' by Malinowski and 'reinter-pretation' by Herskovits. 7. This process was a kind of 'reorientaion'. 8. The change of clothing which was affected by the tradition, for example, robe for the ancestral rites was evolutionary than others. 9. Clothing elements based on mental or internal characteristics like which clothing was hardly changed by compulsion or extortion. 10. The external trends of clothing change during this period were simplicity, utility, and decrease of status symbols.
