The purpose of this study is to verify the relationship between mission-oriented Command, organization efficiency, organization culture of 626 field officers in JFMU. Firstly. the study found that decision making in the relationship between mission-oriented command and organization efficiency had negative effect on job satisfaction. Planning and trust lead to positive effect on job satisfaction and organizational commitment and no significance in self decision. Secondly, mission-oriented command may differ depending on the types of organization culture and organization culture has positive effect on job satisfaction and organizational commitment. Thirdly, mission-oriented command has some effect which derives from its impact on organization efficiency that also effects rational culture and rank hierarchy culture. These study results suggest different measures in terms of practice and policy. Firstly. within the military organization, precise communication will lead to job satisfaction without unnecessary overload of communication. Also. we have rationale culture, agreement culture and rank hierarchy culture forming our organization culture. There is a need to apply elements of mission-oriented command depending on the types of organization culture. Secondly, to maximize organization performance through mission-oriented command, we have to strengthen the rationale and rank hierarchy cultures and especially introduce development culture which should be established within the military organization.

To evaluate the efficiency of anther floating culture according to the maturing group, the varietal difference and classification of fifty varieties was conducted in N6 liquid medium containing 1mg $l^{-1}$ NAA, 0.25 mg $l^{-1}$ kinetin. The efficiency of callus induction was widely ranged from 0 to 113.4%, but the mean callus induction was not significantly different among maturing groups. The efficiency of anther floating culture showed the highest variation in early-maturing group among three maturing groups. The varieties with the best callus induction were Sambaegbyeo and Jinbuolbyeo, while the recalcitrant variety was Obongbyeo in early-maturing group. The efficiency of plant regeneration showed the highest trends in late-maturing group among three maturing groups. The fifty varieties were classified into three groups (distance=0.78) by cluster analysis based on the callus formation and plant regeneration. Group including only two varieties, Shinunbongbyeo and Sambaegbyeo had the excellent androgenic efficiency, and the medium efficiency of Group was included thirty-six varieties. Whereas twelve varieties, including three Tongil varieties were fell into the bad efficiency of Group. Especially, Tongil varieties containing Japonica rice, Obongbyeo were the recalcitrant genotypes for the anther floating culture.

Physiological analysis of swimming in 13 (age:16.3 years, freestyle swimming) and 15 (age:17.2 years, breast stroke swimming) high school boys through oxygen uptake and oxygen debt measurements were performed. The following results were obtained. 1. In freestyle swimming oxygen debt was greater and mechanical efficiency was lower in subjects with less speed. In beginner efficiency was only 1.35%, whereas, in a more skilled subject it ranged to 4.28%. The mean efficiency was 2.59%. 2. In freestyle swimming the speed-oxygen debt curve was convex to the speed axis and the curve shifted to the right the more the speed was greater. 3. Maximal oxygen uptake in breast stroke swimming was 2.51 l/min or 41.8 ml/kin/kg and was 79.3% of treadmill running. Maximal pulmonary ventilation in breast stroke swimming was 73.1 l/min and was 87% of treadmill running. Maximal ventilation equivalent was 2.89 liters. 4. In subjects with greater speed of breast stroke swimming maximal oxygen uptake and mechanical efficiency of swimming were greater. The mechanical efficiency of breast stroke swimming averaged 1.08% $(range:0.51{\sim}1.70%)$. The coefficient of correlation between speed and efficiency was r=.87.

Although somatic cell nuclear transfer (SCNT)-derived embryonic stem cells (ESCs) in pigs have great potential, their use is limited because the establishment efficiency of ESCs is extremely low. Accordingly, we tried to develop in-vitro culture system stimulating production of SCNT blastocysts with high performance in the colony formation and formation of colonies derived from SCNT blastocysts for enhancing production efficiency of porcine ESCs. For these, SCNT blastocysts produced in various types of embryo culture medium were cultured in different ESC culture medium and optimal culture medium was determined by comparing colony formation efficiency. As the results, ICM of porcine SCNT blastocysts produced through sequential culture of porcine SCNT embryos in the modified porcine zygote medium (PZM)-5 and the PZM-5F showed the best formation efficiency of colonies in α-MEM-based medium. In conclusion, appropriate combination of the embryo culture medium and ESC culture medium will greatly contribute to successful establishment of ESCs derived from SCNT embryos.

A large quantity of ethylene glycol(EG) is remained in the effluent after pretreating polyester weight-loss wastewater physicochemically in the fist stage and must be treated biologically in the second stage. Therefore, an excellent EG-utilizing bacteria strain was isolated from the natural system and the optimal culture conditions of the strain were investigated. The optimal culture conditions of temperature, pH, and nitrogen source were found to be 35$^{\circ}C$, 7.5 and ammonium chloride, respectively, when CODCr removal efficiency was more than 90%. The growth of stains and EG removal efficiency was slightly improved by adding elements such as niacin and biotin. With increasing inoculation size in a batch culture, the removal efficiency of EG was conspicuously increased. Growth rate was inhibited when the initial concentration of EG was more then 30g/L. The strain was identified as Pseudomonas sp. based on morphological and biological characteristics and named as Pseudomonas sp. EG1.

Strains degrading and decolorizing acid dyes, Nylosan red E-BL 150%. were isolated from natural system, was named as ARK3. The optimal culture conditions of temperature and pH were $35^\circ{C}$, 7.0, respectively. Growth rate of cells in conditions of aerobic shaking more than standing culture conspicuously increased, and optical density of those to strain ARK3 were found as 1.38 and 0.25 after 42 hrs. Decolorization efficiency in batch culture which used as immobilization media to natural zeolite was 15% after 6 hrs, while suspension culture was 5%, also its of immobilization and suspension culture were 90% and 85% after 48 hrs, respectively. Decolorization efficiency of air-lift bioreactor was more than 90% to a dilution rate of $0.038hr^{-1}$, but that was decreased as 70%, when the dilution rate was $0.05hr^{-1}$. Even though at maximum dilution rate of this study, there was not appeared "wash out" phenomienon of biomass. Decolorization efficiency was 97.7% at a dilution rate of $0.025hr^{-1}$, when influent dye concentration was $100mg/\ell$. But if influent dye concentration increased as $150mg/\ell$, even though MLVSS increased, that of treatment water decreased as 93%. Also, when influent dye concentration increased as $200mg/\ell$ and $300mg/\ell$, decolorization efficiencies of treatment water abruptly decreased as 85% and 63%, respectively. Decolorization efficiency was more than 92% to the limit volumetric loading rate of $3.75mg/\ell\cdot{hr}$hr, without regard to variation of influent dye concentration or hydraulic retention time. if volumetric loading rate was more than $3.80mg/\ell\cdot{hr}$, at same condition, decolorization efficiency was lower decrease of retention time than increase of influent dye concentration.entration.
