  • Previous findings on Organizational Citizenship Behaviors is a useful index for effectiveness of the organization. Also, it is a factor that explains the relation between its member's attitude and behavior as organizational commitment had been stabilized. Since autonomy and rapidity has become more important in increasing the efficiency of the organization, this means Organizational Citizenship Behaviors has become important in it. Organizational Citizenship Behaviors of the members occurs only when discretion and autonomy are given to its members. Therefore, this study aimed at measuring the effects of police officer's personal dispositions on organizational citizenship behaviors, exploring the moderation effect of organization culture, and providing the basis with implications to promote the Organizational Citizenship Behaviors in the police Organization. By reviewing previous finding, Police Officer's Personal Dispositions were selected as independent variables, Organizational Citizenship Behaviors was selected as dependent variable. and Organizational Culture was selected as moderation variable. The result of analysis showed that The belief & The Norm influenced in Organizational Citizenship Behaviors(positive), and The Value in Organizational Citizenship Behaviors(negative). And The moderation effect was tested: The Value${\rightarrow}$Hierarchical Culture${\rightarrow}$Organizational Citizenship Behaviors(negative), The belief${\rightarrow}$Rational Culture${\rightarrow}$Organizational Citizenship Behaviors(negative)

  • In order to select suitable bioreactor type inhibiting cell stress during submerged culture of Tricholoma matsutake mycelium, the growth characteristics and ergosterol contents were investigated using the external-loop type of air-lift bioreactor (ETAB), balloon type of air bubble bioreactor (BTBB) and column type of air bubble bioreactor (CTBB). Dry weights of the T. matsutake in the BTBB, ETAB and CTBB were 12 g, 11.4 g, and 9.5 g per 1 litter, respectively. BTBB, ETAB and CTBB reached stagnant phases 16, 20, and 24 days after cultivation, respectively, The BTBB was more suitable for liquid culture of T. matsutake mycelium compared to other bioreactors owing to much mycelia product and short culture period. The ergosterol contents produced by the mycelium in the bioreactors were in sequence of BTBB, CTBB, and ETAB at every growth phase. BTBB might affect the mycelium on producing the smallest size of pellets. BTBB and CTBB got the mycelium precipitated and coagulated under operation of bioreactor sparser, whereas ETAB shown no effect of above phenomenon. A renovated bioreactor combined between a balloon shape of BTBB and an external-loop of ETAB was developed to enhance the efficiency of culture technique.

  • The goal of cell stem cell technology is to produce a viable and genetically normal animal. To achieve this goal various laboratories have followed 2 different pathways beginning with either the culture of 1) single or pooled ICMs grown with or without a feeder layer or 2) single or pooled 16-20 cell stage embryos grown with a feeder layer. Also, thus far embryonic cell cultures or lines have been established by several methods including loose suspension culture for short-term cultures and more commonly murine or bovine fibroblast feeder layers for long-term culture. Pluripotent lines have been derived from 16-cell through blastocyst inner cell mass stages. The efficiency of establishing cell lines and cell proliferation apper to be affected by the number of cells or embryos starting the line. Most attempts to produce offspring from long term STO cell feeder layer cultured ICM or morulae derived ES cells have resulted in pregnancy failure in the first trimester when ES cells were used in cuclear transfer or have failed to retain ES cells in the progeny produced by chimerization. The exception is 1 chimeric fetus from use of morula ES cells in the chimerization with early embryonic cells. There is much to be learned yet about ES cell culture requirements for maintenance of totipotency. If bovine ES cell lines loose imprinting pattern and totipotency with long-term culture and passage as suggested for mouse ES cells, we may be limited to the use of short-term cultures for multiplication of embryos and efficient production of transgenic animals. No bovine ES cell system has yet met all of the criteria indicated for a totipotent ES cell line.

  • To detect the effects of gelling agent brands and concentration on rice anther culture, anthers of rice(O. sativa L. japonica, cv, Nagdongbyeo) were inoculated on N6-Y1 basic media supplemented with 0.4~1.6% Bacto agar(Difco, 04140-01), Agarose(Sigma, Type 1) and 0.2~0.8% Gelrite(Kelco, 143364) as gelling agents. On 0.4% Bacto agar and Agarose media, the frequency of callus formation which was significantly decreased in proportion to gelling agent's concentration was 39% and 55%, respectively. On 0.6% Gelrite media, the frequency of callus formation which was not statistically significant among the 0.2~0.8% concentration was 44%. Calli derived from the higher concentration of gelling agents showed embryogenic with slow growth, small, whitish and hard shape compare to that of the lower concentration. The frequency of green plant regeneration was high not only in calli derived from the higher concentration but also in plant regeneration medium with the higher concentration after callus transfer. Calli derived from the higher concentration was effective to maintain the frequency of green plant regeneration up to 60 days after anther inoculation. Introduction of 0.6~0.8% Geltite for callus formation, then transferred 1.6% Bacto agar and Agarose or 0.8% Gelrite for green plant regeneration was effective to increase anther culture efficiency.

  • To increase the efficiency of the callus induction in anther culture of Schizandra chinensis, the effects of culture stage, low temperature pretreatment, growth regulators, sucrose and gelling agents were tested on Murashige and Skoog's medium. And the effects of ABA and $AgNO_3$ on organogenesis were investigated. The most suitable stage for anther culture was at the middle to late uninucleate stage, of which the flower size was $6.2{\pm}0.6{\times}4.0{\pm}0.4mm(Length{\times}width)$, and the frequency of callus induction was 13.3%. The effect of low-temperature pretreatment on callus induction was highest as 12.5% in the trearment for 8 days at $4^{\circ}C$. The combination of 1.0 mg/L 2, 4-D and 0.25 mg/L kinetin for callus induction was most effective as 8.3% among various media. The frequency of callus induction was excellent as 10.8% in 4% sucrose. Effect of gelling agents on callus induction was highest as 9.0% on 0.6% Gelrite medium. The prevention of callus browning was effective on the media supplemented with ABA and $AgNO_3$ and rooting was promoted on medium supplemented with 5 mg/L ABA. But shoot was not developed.

  • The purpose of this study is to provide the demand information about services (S/W) and infrastructure (H/W) for rural welfare and culture. The survey was conducted on the overall satisfaction level, the condition change, the importance-satisfaction level of each field and the top priority items for administrative agencies and rural residents. In the overall satisfaction level, administrative agencies responded more than 'normal' to all fields, but the overall satisfaction level was lower than 'normal' in the fields excluding the healthcare field in the case of rural residents. In terms of condition changes compared to the past five years, both administrative institutions and local residents evaluated the improvement. IPA analysis was conducted to identify the priority ranking of each field and it was found that emergency medical facilities in the healthcare field, infant day care facilities in the social welfare field, movie theaters in the culture field, lifelong education institutions and academy facilities in the education field and private sports facilities in the leisure and sports field were most needed, respectively. The results of this study are expected to be helpful in increasing the efficiency and presenting the improvement direction about the development policy of the rural culture and welfare.

  • The effect of different feeding rate on the growth and survival rate of the abalone, Haliotis discus hannai, were investigated in marine net cage culture and indoor tank culture. Feeding rate is determined that was fed 5, 10, 15 and 20 percentage to abalone at body weight once daily : 5 daily feeding rate (DFR), 10DFR, 15DFR and 20DFR. After that, it was conducted to reared during thirteen month with two replicates in net-cage culture and indoor tank culture. In the growth performance of reared abalone (initial mean shell length $54.18{\pm}7.39mm$) in net cage culture, that the absolute growth rate (ARG), daily growth rate (DGR) and specific growth rate (SGR) to the shell length and shell breadth, as well as weight gain (WG), daily weight gain (DWG) and specific weight gain (SWG) to body weight of 20DFR were lower than those of different groups (P < 0.05). Also, survival rates of 20DFR was lower than those of different groups (P < 0.05). In the growth performance of reared abalone (initial mean shell length $49.70{\pm}2.28mm$) in indoor tank culture, that the ARG, DGR and SGR to the shell length and shell breadth, as well as WG, DWG and SWG to body weight of 5DFR and 10DFR were lower than those of different groups (P < 0.05). And also, survival rates of 20DFR was lower than those of different groups (P < 0.05). Therefore, these results is showed that the daily feeding rate for natural feed in net-cage culture and indoor tank culture should be to supply among 5-10 percents, taking into account growth, survival rate and economical efficiency.

  • Nerine from south africa and its sparkling flower shape make us estimate it as a hopeful kind of cut follow. There was a few studies on Nerine in korea. We started this study to set bulb propagation methods. The propagation by tissue culture was changeable according to the growth regulators The best growth regulator combination which makes a lot of Bulblet was NAA $0{\sim}0.5$ + BA $0.5{\sim}2.0mg\;{\cdot}\;L^{-1}$ in Nerine bowdenii ‘Favourite’ and Nerine sarniens ‘Red’ respectively. The adjust culture media source for tissue culture were glucose 9% as a carbon source and ($NH_4+NO_3$) 40mM as a nitrogen source. When glucose was used as a carbon source, Bulblet were harvested a little bit low then sucrose but comparative emergence rate was so high that it is good for carbon source in nerine tissue culture. When we consist culture media as MS+BA $1.0mg\;{\cdot}\;L^{-1}$+sucose 7% + ($NH_4+NO_3$) 40mM, the produced Bulblet were reached up to 1.7 each per bulb and emergence rate was up to 100% irrespective of acclimatization period. The suitable culture explant for nerine tissue culture was scale. When scale was cultured with MS+BA $1.0mg\;{\cdot}\;L^{-1}$+sucose 7%, its propagation efficiency was 54 times greater than using growing point. A proper culture part of the scaly leaf was middle part (8 scaly leaf from outer 8th scaly leaf) when middle part was cultured the number of Bulblet were up to 1.8 each per explant.

  • Dongyi (Chinese: 東夷; pinyin: $D{\bar{o}}ngy{\acute{i}}$; Wade-Giles: Tung-yi; literally "eastern 'barbarians'") was a collective term for people in eastern China and in the east of China. People referred to as Dongyi vary across the ages. The early Dongyi culture was one of earliest neolithic cultures in China. According to the earliest Chinese record, Zuo Zhuan, the Shang Dynasty was attacked by King Wu of Zhou, while attacking Dongyi, and collapsed afterwards Dongyi culture was one of the oldest neolithic cultures in China. Some Chinese scholars extend the historical use of Dongyi to prehistoric times, according to this belief, the neolithic culture correlates to Houli culture, Beixin culture, Dawenkou culture, Longshan culture and Yueshi culture, five evolutionary phases. Deliang He, thinks that Dongyi culture used to be one of the leading cultures in neolithic China. The writing system of Dongyi was one of the oldest writing systems in neolithic China. There are opinions that the 20 pictogram characters discovered in a Dongyi tomb (山東?縣大汶口墓葬) in Shangdong indictates some of the characters found, like "旦, 越, 斤, 皇, 封, 酒, 拍, ?", are still used in Chinese characters. There are also opinions that Dongyi people were the inventor of arrows. Some classic Chinese history records like Zuo Zhuan, Shuowen Jiezi, Classic of Rites, all have some similar records about this. [3][4] The legendary god of archery in Chinese mythology, Houyi, could also be a Dongyi leader. Based on archeology findings, Dongyi people's ancestral worship totem is bird-shaped. In the meantime, The fundamental thing that Koreans should do is to find out Korean identy. Koreans cannot achieve their goals unless they enforce politics economics, educations, etc. in harmony with their own identity. However, some people say that Koreans do not have any dentity on the grounds that there is no Korean traditional thought. This view is, however, absolutely absurd because it is impossible for a nation to exist for oner five thousand years without having it's own native characteristics. The most essential thought in Korean identity is Confucius' In(仁). In is originated from Yi(夷) or Yi-jok(夷族)'s heart. On this account, Confucius' In can be a precious thought to Korean people who have been suffering from many problem caused by the absence of Korean identity. If Korean could understand their original characteristics and if Korean couldrealize that their original characteristics are Confucius' In, then our culture and identity recovery of though may maximize efficiency of country and society development.

  • Poitical demand for decentralization trends in Korea has led the government to plan to localize its agricultural extension system by changing the status of 6,696 extension personnel stationed at the provincial and county level from central government status to local government status as of January 1997. However, serious drawbacks of lowered morale of extension personnel and the financial burden of local governments has not yet been debated extensively for effective personnel management. Some of the findings that emerged from both the analytical and empirical research show the dangers of decentralization such as an increase in disparities, jeopardizing stability, and undermining efficiency. These problems should be considered along with the culture, tradition, and Koreans' attitude towards central and local government. The dangers of decentralization of agricultural extension services in Korea may cause serious problems in allocative efficiency because of a mismatch between available resources and promised expenditures, and in production efficiency because of unproven cost-effective provisions of local governments. It is accepted that the central government can invest more in technology, research, development, promotion and innovation in the agricultural sector. However, changing the status of extension personnel from central government to local government status may lead the best people to leave, lower morale, shake the sense of public service, break networks, and sacrifice investment in research, development and extension. In deciding the future directions for personnel management of agricultural extension services in Korea, maintaining or reinforcing the existing national status of extension personnel should be considered along with a reflection of the basic characteristics of agricultural extension services, linkages of research and extension, the financial burden of local government, specialization of extension personnel, unnecessary duplication of investment among local governments, possible national supports to agricultural research and development, and extension under the WTO systems.
