This study was carried out far isolation and characterization of ammonia oxidizing bacteria (AOB) from aquacultural place and sludges of waste water collected in Pusan. One autotrophic AOB, Nitrosomonas sp. and 8 heterotrophic AOB (2 strains of Bacillus sp., 2 strains of Acinetobacter sp., Xanthomonas sp., Alcaligenes sp., Pseudomonas sp., Sphingobacterium sp.) were isolated. and identified. Variation of total nmmonia nitrogen (TAN) and $NO_2-N$ in mineral salt media containing 10mg/ $\ell$ of NHCl for 15 days in differents 9 strains was measured in order to examine the ablitity of ammonia oxidation. TAN was started to reduce after 4 days incubation and ca. 2 mg/$\ell$ of TAN was decreased after 15 days incubation by Nitrosomonas sp., At that time, $NO_2-N$ was produced to 0.023$\~$0.036 mg/$\ell$. Heterotrophic AOB showed the low ability of ammonia oxidation, 0.02$\~$0,04 mg/$\ell$ of TAN was decreased and $NO_2-N$ was produced to 0.01$\~$0.51 mg/$\ell$ after 15 days. When each strain of 8 heterotrophs was incubated in mimeral salt media containing 10 mg/$\ell$ $NH_4Cl$ and 50 mg/$\ell$ glucose, and 50 mg/$\ell$ $NH_4Cl$ and 5 g/$\ell$ glucose, the diminution of TAN was 1.12$\~$3.38 mg/$\ell$ and 1$\~$20 mg/$\ell$, respectively.

이명숙,LEE Myung-Suk 한국수산과학회 1996 한국수산과학회지 Vol.29 No.5

The antimicrobial effects of two disinfectants commonly used in food industry on Listeria monocytogenes ATCC 15313 were studied. The two disinfectants tested were commercial benzalkonium chloride (BAC) and sodium hypochlorite (NaOCl). Their effects were studied on cells suspended in disinfectants (in vitro) and in the sponge model with the disinfectants (in vivo). When cells were exposed to $0\~0.1\%$ BAC and $0\~150\;ppm$ NaOCL for 20 minutes, BAC and NaOCl concentration more than $0.25\%$ and 100 ppm showed the antimicrobial effects respectively. This organism decreased rapidly during the first $0.5\~1$ minute followed by a slower decrease during the rest of the exposure time. Fifteen ml of cell solution $(about\;10^7\;CFU/ml\;in\;the\;TSB)$ was mixed with 15 ml of disinfectants in the sponge $(6.0{\times}4.0{\times}4.0cm)$, BAC and NaOCl concentration more than $0.1\%$ and 300 ppm showed the antimicrobial effects, and at $0.25\%$ and 800 ppm diminished in cell numbers 3-log cycles during the first 20 minutes. In the case of sponge model, 15 ml of cell solution and 15 ml of disinfectants $(0.25\%\;of\;BAC,\;800\;ppm\;of\;NaOCl)$ were suspended in the sponge during 20 minutes, washing with 200 ml of sterilized distilled water, and this sponge was transfered in the 100 ml TBS, and then incubated at various temperature. The cells were increased about 1-log cycle during 24 hrs at $5\~15^{\circ}C$. And the others temperature, the cells growth was in proporation to storage tepmerature and the cells were about $10^9\;CFU/ml$ after $1\~3$ days incubations.

A lactic acid bacteria which showed antimicrobial activity was isolated from dairy products and identified as Lactobacillus sp. according to the morphological, physiological and biochemical properties, which was named Lactobacillus sp. SH 7311. The bacteriocin of Lactobacillus sp. GM 7311 showed a broad range of inhibitory spectrum against some gram positive and negative bacteria. Especially, Proteus mirabilis was highly sensitive to bacteriocin and used as indicator strain for further investigation. The optimal condition for the production of bacteriocin was showed on MRS broth at $37^{\circ}C$ and pM 6.0. Bacteriocin production of this strain cultured under optimal condition was increased late logarithmic phase to early stationary phase. This bacteriocin was fully active at the pH range $2.0\~5.0$, also was stable at $100^{\circ}C$ for 60 min. at pH 5.0, But about $40\%$ of bacteriocin activity was diminished by the treatment of acetone, ethanol, iso-butanol and ethyl ether during 2 hours at $4^{\circ}C$.

However, have been evaluated or investigated systematically. This study was carried out to explore application of complementary treatments for patients with DM. For this survey, questionnaires were developed by researchers and the data was collected from July to October of 1999. Among the 223 subjects, there is one general hospital, one oriental hospital, 15 area C.H.P, ahd 2 area health centers. The results were as follows: 1. The total number of cases was 223 and the average age was 62.85 years old and average duration of DM was 8.1 years. The number of patients who had experience with alternative therapies was 145 (65%). The number of those who have not undergone treatments was 78 (35%). 2. The 43.5% of experienced CAM were advised family and relatives. Only 30.3% approved the effect of CAM and 52.5% said that If another a new CAM is introduced, they will try it. 4. Ninety three kinds of complementary treatments were used. Among the used items, 63.7% was various types of plants, 21.6% was animal material and 14.7% was the mixed group. As a single item, Bombyx Mori (Silkworm) was the most frequently used (10.5%) followed by the bean, mushroom, Morus bombycis (mulberry), Ginseng, Commelina Communis (Dalgaebi), Chinese medicine, root of Rosa rugosa (Haedangwha). 5. Among the used items, Trichosanthes kirilowii Max. Eucommia ulmoides Oliver, Commelina Communis, Aralia elata, pine needle, mulberry fruit, root of Rosa rugosa. Ginseng, Lycii Fructus, Dioscorea radix, Polygonatum odoratum, Cassia tora L, Bombyx Mori, loach, Crucian carp were based upon the pharmacological function of effect for control of diabetes mellitus symptom. 6. In the analysis of the relationships between the general characters of the patients with new complementary alternative medicine try and hospital treatment; 1) The shorter group suffered from DM (p=.038), poor Self-MBG (p=.037) and wanted to try new complementary alternative medicine. 2) The group of DM education experience were carried out hospital treatment well (p=.045).

The purpose of this study is to analyze the patterns of unconsciousness smartphone use by using an app and a self-administered survey on smartphone addiction comparatively and examine differences between recognition and behavior about actual smartphone use and examine how smartphone addiction influences learning. With an app installed in smartphones, this author collected and analyzed data about users’ unconsciousness using patterns for a month. According to the results, there were significant differences found in users’ recognition and actual time for use and also frequency of turning on the display. Also, 22% of the subjects used their smartphone over 8 hours a day, and 76% more than 5 hours. Over 95% turned on the display more than 100 times a day, and in extreme cases, they did more than 300 times. In the meantime, users not only in the smartphone addiction high risk group and the potential risk group but also in the general user group are found to use their smartphone too long and too much and frequently turn on the display. The apps that the general user group is mainly using are entertaining apps, and their school records are rather good, so excessive use does not always lead to addiction or learning disorder. Therefore, if we develop more diverse contents for learning and provide digital literacy education, smartphone use will bring more positive effects instead. In follow-up research, the app should be corrected to collect more accurate information, and as variables in personal areas, this researcher will also measure depression, anxiety, stress, self-esteem, and emotional control, and so on to see how they are associated with smartphone use.

This study intended to verify the relationship of job satisfaction perceived by airline crew with customer orientation. In addition, it aimed to verify the moderating effect of compensation methods on the relationship between airline crew’s job satisfaction and customer orientation. To achieve the purpose of this study, the experimental design was used with 326 undergraduates from B University and D University located in Busan in order to find out causal relationships among variables and to test hypotheses. The analysis of the data showed the following three characteristics. First, customer orientation was analyzed according to airline crew’s job satisfaction. As a result, it was found that there were significant differences in customer orientation according to job satisfaction, and that customer orientation was higher in case of high job satisfaction than in case of low job satisfaction. Second, customer orientation was analyzed according to the methods of compensating airline crew for their performance. As a result, it was found that there were significant differences in customer orientation according to compensation methods, and that customer orientation was higher with emotional reaction induction compensation than with cognitive reaction induction compensation. Third, customer orientation was analyzed according to airline crew’s job satisfaction and compensation methods. As a result, in the event of low job satisfaction, customer orientation was found to be higher with emotional reaction induction compensation than with cognitive reaction induction compensation, and thus it could be expected that the higher the airline crew’s dissatisfaction with job environment, the more effective the emotion reaction induction compensation. It may be said that the findings of this study have academic values in that it verified, by means of the between-subjects factorial design and the scenario technique, the relationships among the condition of job satisfaction (satisfaction or dissatisfaction) perceived by airline crew, customer orientation, and compensation methods (emotional reaction induction compensation or cognitive reaction induction compensation).
