기업 경쟁력의 원천은 사람이며, 성공 핵심은 사람들의 능력과 협력에 달려있다. 따라서 종업원들의 직무만족과 업무몰입을 위해 CEO는 윤리경영을 실천하고자 다각적인 노력을 해야 한다. 경쟁은 물론이고, 고객의 자산을 관리해야하는 증권회사의 경영자도 수없이 많은 윤리적 이슈와 문제에 직면해 있다. 금융환경은 더 복잡해지고 증권사에 대한 요구도 증가하고 있다. 이러한 현실을 고려할 때, 어떻게 윤리 차원의 사회적 요구를 받아들이고 의식 수준을 변화시킬 것인가, 어떻게 기관 내부의 풍토로 정착시켜야 할 것인가 하는 문제는 중요한 관리대상이 되고 있다. 또한 이러한 윤리경영이 조직 구성원의 업무몰입에 어떤 영향을 미칠 것인가를 파악해 볼 필요가 있다. 본 연구는 이러한 연구목적을 바탕으로 증권회사 CEO의 윤리경영의지가 종업원의 심리적 성과변수인 조직몰입에 영향을 미치는 정도를 확인하고자 하였다. 연구를 통해 금융기관장들은 기업윤리 위반의향이 유발되지 않도록 경영제도를 개선하고, 기업윤리 준수의향을 향상시키는 방안을 모색할 필요성이 제기되었다. 또한, 증권회사 CEO는 구성원들의 협력을 유도할 수 있는 참여적 방식에 바탕을 둔 민주적 경영관리와 윤리의 정당성에 초점을 두고 경영방침을 세워야 할 것이다. 아울러 민주적 리더십과 윤리경영을 발휘하기 위한 새로운 도구를 개발하는데 지속적인 노력을 기울여야 할 것이다.

On 11 June 1991, eggs from the brood stock of small yellow croaker (Larimichthys polyactis) were artificially fertilized using the standard dry method and were hatched. Each of the fertilized eggs (1.1-1.2 mm in diameter) had an oil globule and was transparent and buoyant. The fertilized eggs hatched in a range of water temperatures $(17.5-20.3^{\circ}C)$ 44 hrs after fertilization. The total lengths of the newly hatched larvae were 3.1-3.3 mm, and these hatchlings had 31 myotomes (10+21). Melanophores and yellow-brown chromatophores were concentrated on the head, at the ventral part of the yolk, and in the middle of the tail. Four days after hatching, the larvae completely absorbed the yolk and became flexions of 5.1-5.5 mm in total length. Fifteen days after hatching, one spine (the anterior tip of the maxillary) appeared in the upper jaw and three spines developed at the upper parts of the eyes and on the posterior part of the head. At this stage, the larvae were approximately 8.3 mm long. Thirty-nine days after hatching, juveniles (1.9-3.4 mm in total length) had a pointed tail fin. By 66 days after hatching, the juvenile fish (about 4.0-6.5 mm in total length) were similar to adult fish in body shape. The larvae of L. polyactis could be distinguished from those of L. croacea by two distinct characteristics: the large number of vertebrae (28-29), and a relatively small bony ridge on the occipital region of the head.

본 실험은 다양한 유기질 퇴비의 시용이 Sorghum${\times}$Sudangrass hybrid의 생산성, 사료가치 및 가축사육능력에 미치는 영향을 검토하였고, 그 결과를 요약하면 다음과 같다. Sorghum${\times}$Sudangrass hybrid의 건물수량은 FPM이 19.60ton/ha로 가장 많았으나, PBC와의 유의한 차이는 없었다. 상대사료가치는 1회 예취에서 PBC가 80.66으로 유의하게 높았으나, 2회 예취에서는 FCM을 제외한 모든 시험구에서 유의차를 보이지 않았다. 가축사육능력은 $K_{CP}$와 $K_{TDN}$의 평균값으로 비교해 보았을 때, FPM이 9.45두/ha/yr로서 가장 높은 값을 보였다. 따라서 Sorghum${\times}$Sudangrass hybrid의 유기 재배 시 FPM이 생산성, 사료가치 및 가축사육능력에 있어서 다른 유기질 퇴비에 비해 좋으며, 유기질 퇴비의 연용 시에는 다른 가축분과의 혼용을 통하여 계분의 부족한 유기물을 충족시켜 준다면 작물 및 토양에 있어서 더욱 좋을 것으로 판단된다. 또한 적절한 혼합 비율에 대한 추가적인 연구가 필요할 것으로 판단된다.

Stainless rolling stocks are usually fabricated by spot welding process without painting. Indentation on the surface of the car body after spot welding injures the beauty of the stainless rolling stocks. In this study, insulated electrode tips to reduce the indentation are developed and applied to the actual spot welding works. The developed tips are composed of head, neck, hole for cooling water, body and resistance material. They provide large surface contact area with the base materials during spot welding and enhance the current density by necking. Experimental results using the developed tips show that small indentation and sufficient tensile shear strength is produced due to large contact area and enhanced current density.

Purpose - This study is to propose a creative idea for constant business growth and development by examining characteristics of business outcomes by phase, which are "growth" and "erosion and stagnation," respectively. Research design, data, methodology - It is necessary to identify an occurrence of crisis and its diffusion with a dynamic model in order to identify a success and failure of businesses in an organic way, not on a binary structure. The static perspective is to understand a crisis as a simply one-time event or as a linear causation. Thus, it has a limited understanding of the overall situation and has limits to investigating a foundational cause and developing long-term countermeasures. On the contrary, the dynamic perspective is to understand the crisis as circulation process of the overall system. Thus, it divides elements of the crisis as external and internal ones to understand it as the causal relationship of each element. Results - During the growth period of Burger King, the company promoted its brand very successfully with aggressive and creative marketing activities. However, due to the founder's disposal of management rights and the following changes in the management, the company had no choice but to lose focus on its business philosophy and brand management, and eventually it had to face the big crisis (resonance) which was delisting from the stock market because of the external threat; well-being trend. However, Burger King resumed lifting on the stock exchange by making great efforts to clearly identify the current issues and seek solutions. Under the spirit of "perseverance" and its slogan "Have it your way" the company is now going head to head with McDonald's in the North American region and emerging countries. Conclusions - Then, what is the most crucial factor in the success and failure of businesses? Answers may vary, however, as learned from the case study of Burger King, corporations should inspect the present and focus on developing a long-term strategy for the future and actively fulfill the actions. McDonald's may not be able to innovate by itself in the future as it may become routinized to the growth. There will be chances of winning if we change conditions of individuals or organizations to an organic system in terms of being creative. There is a hopeful message here that an individual or small business may have more advantages in the era of the idea and innovation.

Duck viral hepatitis is an acutic, highly infectious viral disease of young ducklings. The most practical means for controlling duck viral hepatitis is the vaccination of ducklings or of a breeding stock. We attempted to develop a vaccine strain of duck hepatitis virus (DHV) using a Korean isolate by serial chicken embryo passages. The propagation of DHV in chicken embryos was carried 140 passages. After the $50^{th}$ passage, of which the virus was non-pathogenic for ducklings, approximately every $20^{th}$ passage of the virus was tested for vaccinal efficacy. Both the $70^{th}$ and $90^{th}$ passage of the virus gave good protection against challenge infection to a DHV-DRL reference strain(type 1) and a virulent Korean isolate. The $110^{th}$, $125^{th}$ and $140^{th}$ passage of the virus were less protective than the $70^{th}$ and $90^{th}$ passage, which means that more than $110^{th}$ passage may lead to over-attenuation of the virus. Ducklings vaccinated with the chicken-embryo-adapted virus by oral, intramuscular or eye drop administration showed earlier resistance to challenge infection from 3 to 7 days postvaccination. Of the above methods, ducklings vaccinated intramuscularly presented the most rapid resistance against challenge. The minimum immune dose of the chicken-embryo-adapted virus in ducklings was also studied. Ducklings inoculated with a dose of $10^{2.0}\;ELD_{50}$ and below were not fully protected against challenge with a virulent DHV, showing a protection rate of 67% to 73%, but ducklings inoculated with a dose of $10^{3.0}\;ELD_{50}$ and over were completely protected. The virus yield of the chicken-embryo-adapted DHV was examined at 24hrs and 48hrs of the incubation time in the allantoic fluid, embryo head and embryo minus head of the embryonating egg. In all three components, the titer of the virus was higher at 48 hours than that at 24 hours after incubation. And the titer of the virus was higher in the embryo minus head, embryo head and the allantoic fluid, in order. Field trials for evaluating the efficacy of the attenuated DHV as a live vaccine were done in duck farms with about 25% mortality of flocks resulting from duck viral hepatitis. After the use of the experimental vaccine, the mortality due to duck viral hepatitis was dramatically reduced in the farms. These results indicated that the attenuated DHV using a Korean isolate could be a good candidate as a live vaccine strain of DHV in Korea.

To facilitate estimation of the barbel size of a striped sea catfish, Plotosus lineatus Thumberg total length (TL) and head length (HL) against body weight (BW), HL against TL, and 1st maxillary barbel $(MxBL_1)$, 2nd maxillary barbel $(MxBL_2)$, 1st mandibular barbel $(MnBL_1)$ and 2nd mandibular barbel $(MnBL_2)$ against HL were regressed. The relationship of TL and HL for BW were described by the equation $TL=50.9373BW^{0.3072}\;(r^2=0.9898)$ and $HL=11.2938BW^{0.3144}(r^2=0.9572)$, respectively. The relationship of HL for TL was described by the linear equation $HL=0.1982TL+2.1996(r^2=0.9568)$. The relationship of each barbel for HL described by the equation of $HxBL_1=0.04420HL+0.3105(r^2=0.9615),\;MxBL_2=0.4592HL+0.5321(r^2=0.9519), MnBL_l=0.4057HL+1.9824 (r^2=0.9465)\;and\;MnBL_2=0.4355HL+1.8010(r^2=0.9429)$. Knowledge of the relative growth patterns about each barbel of this species is important for the propagation of seed as stock for large-scale striped sea catfish culture.
