  • Organizations continue to invest heavily in the acquisition of knowledge management systems (KMS). The overriding belief is that KMS-task fit will become more productive. A survey of users was conducted to better understand the factors that affect KMS-task fit to better explain KMS performance perspective on knowledge circulation process. This involves stating the research hypotheses among the following constructs: the characteristics of KMS, the fitness of task characteristics, and KMS performance. The findings indicate that the characteristics of KMS positively affect the fitness of task characteristics. The fitness of task characteristics are affecting KMS performance. The results of this study suggest that task-technology fit could be the basis for a strong diagnostic tool to evaluate whether KMS in a given organization are meeting user needs.

  • For the purpose of disclosing the effects of exercise program on physical fitness for health promotion, living activities, and performance abilities of the elderly in the institution, questionnaire survey and physical examination were performed on the subject, aged 65 years or older. The subjects consisted of experimental (33 persons) and control (35 persons) groups, matched with gender and age. The experimental group was put on the exercise program; working their upper and lower limbs for 12 weeks using dumbbell and lead-packed weight. The results were as follows: 1)The mean values of experimental group were significantly higher than those of control group in all variables of physical fitness, in all variables except for living activities, and in all variables of performance abilities after exercise program. 2)The mean values were significantly improved in all variables of experimental group after exercise program, but the mean values were decreased or maintained in most of variables of control group after exercise.

  • Dicarboximide-resistant isolates of Monilinia fructicola grew readily on media amended with dicarbosimide fungicides, and showed cross-resistance to pentachlo-ronitrobenzene (PCNB). The fitness of resistant isolates was inferior to that of sensitive isolates. Mycelial growth on fungicide-free medium was not significantly different between the dicarboximide-resistant and sensitive isolates. The originally high $\textrm{EC}_{50}$ values of the resistant isolate decreased after storage for 16 weeks at $4^{\circ}$. After inoculation with the mixture of spore suspensions of resistant and sensitive isolates, the re-isolation rate of the resistant spores was significantly reduced regardless of the mixing ratio. From the results, it could be concluded that the competitive ability of the resistant isolates is inferior to the sensitive ones.

  • Fitness of clothes becomes a major concern in apparel industry. In order to improve clothing fitness, it's very important to suggest a systematical sizing system. The Purpose of this study was to suggest a standard sizing system for junior-high school girls'lower clothes. The subjects were 402 middle-high school girls of 13 to 15 year-old. 4 clusters were categorized by cluster analysis and the sizing system was classified according to four lower body types. The size intervals of waist girth and hip girth were 3cm and 4cm respectively. The most frequent size were 64-86 in the short and small figure type 1,67-90 in the fattest figure type 2, 61-86 in the average size type 3 and 64-90 in type 4 taller than others types. The sizing system, which had frequencies more than 4%, was classified 9 cases, 11 cases, 8 cases and 9 cases respectively by lower body types. This result will contribute to clothing fitness of consumer and the amount of production.

  • Proper installation of Flexible AC Transmission Systems (FACTS) devices in existing transmission networks can enable power systems to accommodate more power transfer with less network expansion cost. The problem to maximize transmission system loadability by determining optimal locations and settings for installations of two types of FACTS devices, namely static var compensator (SVC) and thyristor controlled series compensator (TCSC), is formulated as a mixed discrete-continuous nonlinear optimization problem (MDCP). For solving the MDCP, in the paper, the proposed method with fitness sharing technique involved in the updating process of the particle swarm optimization (PSO) algorithm, can diversify the particles over the search regions as much as possible, making it possible to achieve the optimal solution with a big probability. The modified IEEE-14 bus network and a practical power system are used to validate the proposed method.

  • A sample of 450 women who attended a physical fitness program in the Ulsan area was selected to study some environmental factors associated with obesity. The women were grouped into two categories, obese and nonobese, based on body mass index(kg/$m^2$). Average BMI of the total subjects was 24.3$\pm$4.8, but 34.7% of the subjects rated equal to or ore than 25 type, which can be considered as obese. The results showed that age, employment status, family type, and food frequency score have a statistically significant association with obesity. However, education level, nutrition knowledge, availability of housemaids, family history of obesity, and house type are not related to obesity . There were no differences in sources of nutrition information between the obese and the nonobese. The above results suggest that health education programs should consider environmental factors as well as health factors in preventing obesity obesity in the community.

  • In this paper, the final fitness results of the satellite mission scheduling algorithm, which is designed by using the genetic algorithm, are simulated and compared with respect to the control constants. Heuristic algorithms, including the genetic algorithm, are good to find global optima, however, we have to find the optimal control constants before its application to a problem, because the algorithm is strongly effected by the control constants. In this research, the satellite mission scheduling algorithm is simulated with different crossover probability and mutation probability, which is major control constant of the genetic algorithm.

  • This study was to evaluate residents' environmental cognition, satisfaction and needs of distinctive outdoor space in apartment housing estates. Distinctive outdoor space of 75 apartment estates throughout the country were investigated. And the residents of 16 apartment estates were asked how they cognize disticntive outdoor space qualities, and what activities they prefer in apartment's outdoor space. Thre important factors were extracted in residents' cognition of distinctive outdoor space qualities. First factor was naturalness of the greenery, second factor was outdoor activities especially related to fitness and exercise, and third factor was design of street furniture. Residents' satisfaction degree of distinctive outdoor space tended to increase as high as the occupied housing area. Places with water, tree shades, pedestrian way, greenery with flowers, playlots, fitness places and entrances of the estates were evaluated high in the order named. And places full with greenery, places related to fitness and exercisem, playlots were prefered by the residents.

  • Combat fatigues are issued to military personnel with ready made clothes. Ready made combat fatigues should be fitted to various bodies of military personnel within given standard size. This paper develops a standard sizes selection method in order to increase the coverage rate and fitness for combat fatigues. The method utilizes a generalized learning vector quantization(GLVQ) algorithm that is one of cluster algorithm in neural networks techniques. The GLVQ moves the standard sizes from initial arbitrary sizes to next sizes in order to increase more coverage rate and fitness. Finally, when it cannot increase those, algorithm is terminated. The results of this method show more coverage rate and fitness than those of the other methods.
