노년기의 활동 가운데 성(性)생활은 매우 중요한 활동임에도 불구하고 지금껏 우리 사회의 유교적 가치관과 노인에 대한 선입견으로 무시되어 온 것이 사실이다. 노골적인 성행위의 노출, 몇 번의 등급보류로 화제가 되었다가 결국 18세 이상 관람가로 결정된 "죽어도 좋아"라는 영화도 노인의 성에 대한 일반인들의 시각을 단적으로 보여주는 예이다. 이런 이유로 노인의 성은 은밀한 곳에서 노골적으로 표면화되어 노인들의 어린이 성추행이나 성범죄, 공원 내 불법매춘 등이 자주 매스컴에 오르내리고 있으며, 노년기의 성을 인정하지 않는 사회문화 분위기로 인해 현실적으로 고통 받는 노인들이 증가하고, 이는 노년의 만족스런 삶의 질 저하에 중요한 요인으로 작용하고 있다. 이와 같은 상황 속에서 만화콘텐츠는 노년기 성교육을 위한 가장 적절한 교구로 활용될 수 있다. 만화콘텐츠의 오락적 기능과 장르적 특성은 대상 노인들에게 성에 대한 이해를 보다 자발적이고, 쉽게 전달할 수 있으며 간접체험에 따른 동기 유발과 효과적인 활동을 위한 교구로서 기능할 수 있다.

There is a growing concern on the improvement of water distribution pipeline for multi-regional water supply system in Korea along with its aging infrastructure. Rehabilitation of large diameter pipeline is more efficient in cost and time compared to replacement with trenching. The procedure for rehabilitation are diagnosis, cleaning, spraying coating material, and final inspection. The internal state of pipeline was carefully diagnosed and got C grade, which required rehabilitation. We found that 17,274,787,000 Korean won could be saved after pipe surface coating because of increased C coefficient of Hazen-Williams equation. Optimal coating material was D polyurea. We also found optimal distance between spraying nozzle and pipe wall to be 70 - 80 cm, which were critical factors for coating quality. This study also illustrated the time for spray drying to be more than 30 min. These results could be used in the quality control process during rehabilitation of aged pipelines.

As recieved boiler tuve steel was aged artificially at $650^{\circ}C$ and$690^{\circ}C$ for various time duration to simulate the material deterioration which could be occurred during the operation of fossiol power plants. And the tensile tests, the microhardness tests and the characterization of carbides formed in the aging process were performed to asses the relationship between the mechanical properties and the effect of thermal aging. Furthernore, the amout of Mo-rich carbide were investigated by ondestructive method by noticing the fact that formation of Mo-rich carbide were investigated by ondestructive melthod by noticing the fact that formation of Mo-rich carbides($Mo_6C$) which stabilizes lastly affects the mechanical properties. It was known that the microhardness results of service exposed materials were similar to the ones which are aged at $650^{\circ}C$. The room temperature measurement showed small variation in the yield points and ultimate strength in materials aged at $650^{\circ}C$. Those properties at $540^{\circ}C$ showed the abrupt decrease compared with as received material even if short aging time. And it was found that $650^{\circ}C$ $690^{\circ}C$ aging cause different effects on mechanical properties, although the temperature time parameters(LMP;Larson-Miller parameter) are same. And it was concluded that the aigng at $650^{\circ}C$ is more appropriate to simulate the service exposed condition. Finally, the relationship between high temperature tensile properties and Ip values were established, which offers a potential way of reliability tests onthe power plant components.

The purpose of this study was to identify the preferred materials and design characteristics of nursing home clothes in order to collect the basic data necessary for the elderly nursing home clothes. It was to utilize the elderly nursing home clothes considering elderly body shape, hand function, illness. This study was conducted by questionnaire method and SPSS ver. 20.0 program was used. The preference for nursing home clothes material was high for cotton, and it was found that they prefer soft, stretch material, warm feeling material, and lightweight material. In the hygienic aspect, they favored sweat-absorbent materials, and preferred laundry- care-resistant materials with poor wrinkles and dirtiness. The nursing home clothes preferred a two piece form consisting of a round neckline, two pockets on both sides, a waistband of rubber band, long lengths, and a waistline pants. The most important function in the nursing home clothes was recognized as wearing comfort. Aesthetics, symbolism, color and print pattern were recognized as not important functions. Therefore, it is necessary to focus on the functional part such as wearing comfort in the design of the nursing home clothes. The material is also hygienic and comfortable to wear. In the case of the elderly, it is necessary to provide convenience for the wear of clothes through the development of stretchable material and detachment device since the movement range of muscles, arms, and legs is reduced. Based on this study, we will utilize it for the development of nursing home suit considering the characteristics of elderly person in the elderly society. It is to develop functional materials for the elderly in need of nursing home, to develop the pattern considering the elderly body shape, and to develop the desorption device considering the movement of the hand.

HVDC technology has become popular as an economic mode of bulk power transmission over very long distances. Polymeric insulators in HVDC power transmission lines are affected by surface tracking and erosion problems due to contamination deposit, which pose a greater challenge in maintaining the reliability of the HVDC system. In addition, polymeric insulators are also naturally affected by aging due to various environmental stresses, which in turn accelerates the surface tracking and erosion problems. Research works towards the improvement of tracking and erosion resistance of polymeric insulators by adding nano-sized fillers in the base material are being carried out worldwide. However, surface tracking and erosion performance of nano-filled aged polymeric insulators for HVDC applications are not well reported. Hence, in the present work, tracking and erosion resistance of the nano $Al(OH)_3$ filled silicone rubber insulation material has been evaluated under DC voltages at different filler concentrations and aged conditions, as per IEC 60587 test procedures. Leakage current and contact angle measurements were carried out to understand the surface hydrophobicity. Moving average technique was used to analyze the trend followed by leakage current. Water aged specimen shows less tracking resistance when compared with thermal aged specimen. It is observed that nano-filler concentration of 5% is even sufficient to get better tracking/erosion resistance under DC voltages.

This study was undertaken as a useful material not only to understand the clothing behaviors and the personal variables (age, education, occupation, yearly clothing expenses, weight, and persons who influence on one's choice of clothes) of the middle-aged women in Seoul, Korea but to lend itself to other uses concerning attitudes toward clothing. For the measurement of the attitudes toward specified activities related to clothing use, attitude method by Mary F. Pasnak (1968) was reworded and modified for use with the sample for this study. Analysis of the data revealed that the clothing behaviors of 450 women 30 to 59 years of age made a significant difference according to the personal variables. First, women in thirties showed the most positive clothing attitude of the three age groups. The younger age groups were positively related to relief from boredom through clothing, intensity, sureness, and involvement of attitude among eight attitudes related to clothing. Second, the positiveness of relief from boredom through clothing, intensity, sureness, and involvement of attitude increased in proportion to the education level. On the other hand, dressing for self was negatively related to the level of education. Third, a significant relationship was found between the amount of the clothing expenses and dressing for others, tactual pleasure through clothing, intensity, sureness, and involvement of attitude. Among the personal variables of the middle-aged women, age, the educational level, and the clothing expenses have a relationship with the clothing behaviors, while job, weight, and the persons who influence on one's choice of clothes have no relationship. The extensive interpretation on the result of this study will have to be taken with deliberation. For the more practical material researches on the clothing behaviors of the middle-aged women should be continued steadily in every possible way.

This research aims to measure mechanical tensile properties of CFRP composites for cryogenic tank material. Through the cryogenic chamber, tensile tests are peformed under cryogenic temperature for graphite/epoxy fabric specimen aged at $-150^{\circ}C$ for 30hrs with load and graphite/epoxy unidirectional specimen 3-cycled from RT to $-100^{\circ}C$ with load. For graphite/epoxy fabric specimen, tensile modulus showed to increase after aging at cryogenic temperature(CT) while to decrease after aging at room temperature(RT) and tensile strength is more decreased after CT-aged than at RT-aged. For graphite/epoxy unidirectional specimen, tensile modulus was almost not changed after 3-cycling but strength showed the trend of decrease as increase the number of cycling.

As a cathode material of lithium rechargeable batteries, charged Li[Co0.1Ni0.15Li0.2Mn0.55]O2 electrodes, which were aged thermally at 25 oC and 90 oC respectively, were characterized by means of charge/discharger, impedance spectroscopy, and X-ray diffraction. The discharge capacity diminution of the electrodes aged at 25 oC and 90 oC for 1 week was 4% and 23%, respectively. The cell aged at 25 oC was recovered on cycling. However, the capacity loss after ageing at 90 oC was not recovered in a subsequent cycling test, which demonstrates that the reaction occurring during ageing at 90 oC is irreversible. A significant impedance increase of aged electrode at 90 oC is associated with irreversible capacity loss. The structural changes including phase transformation were not detected by XRD analysis, because it could be due to out of detection limit. After ageing, impedance was slightly decreased during subsequent cycling test. It could be explained the cyclic performance of aged sample is stable. The thermal stability was not deteriorated by ageing even at the high temperature of 90 oC.
