본 연구의 목적은 가족기업의 핵심역량 축적과정을 살펴보고 성공적인 가업승계의 중요성을 논의하는 것이다. 이를 위해 가족기업의 경쟁우위를 설명한 Miller and Le Breton-Miller (2005)의 4C(Continuity, Community, Connection, Command)모델을 기반으로 3대에 걸친 성공적인 가업승계를 기반으로 한 에스엘의 핵심역량 축적과정을 조사했다. 국내 자동차부품회사인 에스엘의 성장과정에 관한 2차 자료를 분석하고, 대표이사와의 심층인터뷰를 통해 그 연관성을 구체적으로 살펴보았다. 분석결과 창업자 가족이 공유한 가치관과 비전, 노하우, 경험 등은 장기적인 지향성을 가지고 지속적으로 핵심역량을 개발하는데 큰 역할을 하였다. 또한 신뢰의 가치관이라는 사회적 자본을 효과적으로 전달받은, 다음 세대의 후계자는 가족 가치관을 토대로 대외 네트워크를 더욱 견고히 하고 지속적으로 발전시켰다. 에스엘은 성공적인 가업승계로 소유와 지배구조를 집중화 할 수 있었고, 이에 따라 외부 이해관계자들의 압력 없이, 가족 내부 조화를 통해 독립적이고 과감한 의사결정이 가능하였다. 이는 가족기업의 경우 고유한 공동체적 문화와 신뢰에 기반 한 외부 네트워크 형성을 통해 경쟁력 구축에 힘쓸 필요가 있으며, 일반기업의 경우에도 공동체 적 조직문화와 중장기적 관점의 외부 협력관계가 기업의 영속성 유지에 중요하다는 시사점을 제공한다. 또한 가엽승계가 기업경쟁력의 유지와 세대 간 이전에 중요한 기능을 함에 따라 이에 대한 적절한 정책적 배려가 필요하다. The purpose of this study is to examine the process of accumulating com-petences and competitiveness by family companies, and discuss the importance of successful succession of a family business. The core competence accumulation process and competitiveness sources of SL, which is based on successful succession of the family business for three generations, was examined based on the 4C (Continuity, Community, Connection, Command) model of Miller and Le Breton-Miller (2005), which explains the competitive superiority of family companies. Secondary data on the growth process of SL, a domestic auto-mobile parts company, was analyzed and their strategic implications were examined in detail through an in-depth interview with the CEO. The 4C factors, which are antecedent variables of a successful family business, played an important role on the growth process of SL. The continuity factor existed through continuous research and development that focuses on and invests in improving technology quality such as mold pro-duction, lamp production, sash production, and design automation. 2 to 3 percent of the sales amount each year was spent on research and development, regardless of the condition of the economy. As a result, the intellectual property of the company reached 1,108 items (583 applications, 440 registered properties, 47 in review, 38 trademarks) by 2006. From a long-term perspective, the company is improving their technical power to an international standard through technical investments. The continuity of investments in research and development is apparent through three generations, and it can be said that this reflects the characteristics of family business management that shares a goal, and confirms and develops the core capacities of the company. The factor of community started with the "people first" business, management philosophy of the late presi-dent, Hae-joon Lee. Then, it expanded to "human respect" during the president Choong-kon Lee`s generation, and to "ethical management" for the CEO Sung-yup Lee`s generation. The sense of community was revealed to be in the form of a community corporate culture based on a good welfare system for employees and com-munity awareness. Diverse benefits including a housing support system, housing fund support system, child-ren`s education fee support system, scholarship system, and company clubs support system were used to make people feel like "the company and I are one" and work with a sense of ownership. The fact that there has not been one conflict between labor and management since 1968, when the labor union was first established, is especially a noteworthy point. The business management based on "people first" stresses the responsibility and roles of employees and reflects the belief that a workplace should not simply be a place to make a living, but a part of life where you can cultivate character and fulfill your role as a member of society. The connection factor appears as continuous partnerships and networks with domestic and international parts suppliers and technologically advanced companies. The late honorary chairman Hae-joon Lee maintained partnerships and networks with Hyundai Motor Company and Daewoo Motors. Then, chairman Choong-kon Lee expanded the network to include KIA and Ssangyong Motors and maintained long-term relationships with domestic automobile makers. In addition, the company is maintaining cooperative relations with the Japanese company Stanley and German company Hella, and has started dealing with the U.S. company GM, too. CEO Sung-yup Lee`s generation improved the company`s relationship with GM and made the achievement of re-ceiving the QSTP Award (an award GM gives to selected skilled companies out of all the parts companies in the world) from GM for 14 consecutive years (1997-2010), solidifying its position as a skilled partner of GM. SL is also advancing into China through collaborations with the local branch to extract new cooperative relations. The value of "trust" is the motivation that helped SL maintain and strengthen relationships and networks. This value started with the founder of the company and was handed down to chairman Choon-kon Lee and CEO Sung-yup Lee, and worked as a core factor to strengthen external cooperative relationships. The factor of command is apparent from the decisions of business managers who take on a challenge, structural management that includes an endless will for innovation, and leadership. When the late honorary chairman Hae-joon Lee could not cultivate a road for the automobile parts industry because of smuggled goods, he recognized the importance of the automobile parts industry and folded his bicycle parts business, which was number one in the market at the time, without hesitation thanks to his owner-focused independent and bold decision-making skills. In the mid-1990s, when most automobile production companies experienced difficulties because of the economic crisis where Korea was dependent on the IMF, and the aftershocks of restructuring affected automobile parts manufacturing companies, chairman Choong-kon Lee considered the crisis an opportunity and acquired and merged with Seogu Industry (currently known as SL Litech), Oriental Construction and Poongi Building (currently known as SL Seo Bong Co., Ltd. Shiheung factory), creating a turning point to develop further after the crisis. CEO Sung-yup Lee pursues continuous innovation including a corporate culture that places importance on learning and admitting mistakes, change of the structural system to a project based system, and a human resources system that focuses on human resources management, and is emphasizing corporate changes according to the situation of the times. An examination of the SL core competence accumulation process based on the 4C model shows that it is establishing positive relationships and continuity based on connection and trust, leading to a cooperation sys-tem based on the value of trust. It also establishes a positive relationship with command focusing on a com-munity structure culture, which leads to structure capacity based on community culture. The factors of con-nection and community were found to be especially strong at SL. The factor of connection was a core growth motivation, influenced by the key values of family. SL reveals its growth motivation to be "unification of all employees," shares the goals and visions of family with its employees, and offers a variety of different benefits. The active will of employees to participate in this community is seen to be the background behind big accomplishments such as innovations in the field, which are still being pursued. Successful succession of the family company and family business management are strengths that lie in the center of the motivation that allowed SL to continue to grow for three generations, starting with the founder, the late honorary chairman Hae-joon Lee, who provided a foundation of growth with values of trust and peo-ple first, moving on to the second generation chairman Choong-kon Lee, who accomplished a rapid development of the company based on technological developments and respect for people, and finally through to the third generation CEO Sung-yup Lee, who is making efforts for globalization and innovation based on ethical management and change. This shows that the values of trust set by the founder have continued on for a long time, through his son, chairman Choong-kon Lee, and grandson, CEO Sung-yup Lee. Chairman Lee, CEO Lee and executive director Lee Seung-hoon are learning corporate culture and management know-how through a great will to participate and actual participation in management. SL was able to gain competitiveness and continuously reach excellent management performance through cooperation based on the value of trust and structural management that focuses on community culture. As a result of analyzing the company through the 4C model and conducting in-depth interviews with man-agement, it can be said that the values, vision, know-how and experience the founder shared with his family largely contributed to continuous development of core competence with a long-term goal. This in turn had a positive effect on establishment of a corporate community based on trust. By inducing loyalty, participation, and focus on employees in the organizational structure with something more than just financial incentives, the core values of the company are relayed through generations and play an important role in maintaining the community, and also emotionally motivating members of the community. Another point is that the successor who effectively received the social capital of trust as a value, strengthened and continued to develop the ex-ternal network based on the family values. The value of "trust" started by the founder played a key role in strengthening external cooperative relations as it was succeeded through generations. This had a positive ef-fect on connection based on the value of trust, and especially decisively contributed to maintaining close rela-tions of cooperation in the external network and long-term cooperative relationships. SL was able to focus the possession and domination structure through successful succession of the family business, and make in-dependent bold decisions through internal harmony of the family, without pressure from people involved externally. The results above lead to the following points of discussion regarding corporate management. From a busi-ness management perspective, first, a family company needs to establish an external network based on a unique community culture and trust to work on establishing competitiveness. Second, there is a need to reflect the fact that a community-like structural culture and external cooperative relations from a mid- to 0long-term perspective have an important effect on maintenance of corporate continuity, even for companies that are not family businesses, on business management. Third, there is a need to focus on the fact that a structural man-agement method that uses values such as community help secure continuity of a company. From a policy per-spective, since succession of a family business can be not succession of wealth but succession of accumulated technological core competence and good management philosophy and know-how, it is important for improve-ing national competitiveness, to maintain corporate competitiveness, and transfer the competitiveness between generations. Therefore, there is a need for appropriate policies that support the successful transgenerational succession of family businesses.

A selective cyclin-dependent kinase 4, 6 dual inhibitor, Ribociclib (LEE011) inhibits cell proliferation and induces apoptosis in aggressive thyroid cancer

<P><B>Abstract</B></P> <P>The RB-E2F1 pathway is an important mechanism of cell-cycle control, and deregulation of this pathway is one of the key factors contributing to tumorigenesis. Cyclin-dependent kinases (CDKs) and Cyclin D have been known to increase in aggressive thyroid cancer. However, there has been no study to investigate effects of a selective CDK 4/6 inhibitor, Ribociclib (LEE011), in thyroid cancer. Performing Western blotting, we found that RB phosphorylation and the expression of Cyclin D are significantly higher in papillary thyroid cancer (PTC) cell lines as well as anaplastic thyroid cancer (ATC) cell lines, compared with normal thyroid cell line and follicular thyroid cancer cell line. LEE011 dose-dependently inhibited RB phosphorylation and also decreased the expressions of its target genes such as <I>FOXM1, Cyclin A1,</I> and <I>Myc</I> in ATC. Furthermore, LEE011 induced cell cycle arrest in G0-G1 phase and cell apoptosis, and inhibited cell proliferation in ATC. Consistently, oral administration of LEE011 to ATC xenograft models strongly inhibited tumor growth with decreased expressions of pRB, pAKT and Ki-67, and also significantly increased tumor cell apoptosis. Taken together, our data support the rationale for clinical development of the CDK4/6 inhibitor as a therapy for patients with aggressive thyroid cancer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> pRB and Cyclin D were expressed high in aggressive thyroid cancer. </LI> <LI> LEE011 suppressed pRB and also decreased the expressions of its target genes in ATC. </LI> <LI> LEE011 induced cell cycle G1 arrest and apoptosis, and inhibited cell proliferation. </LI> <LI> LEE011 inhibited in vivo tumor growth with decreased expressions of pRB and Ki-67. </LI> <LI> We could explain the anticancer effects with the RB-E2F pathway. </LI> </UL> </P>

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

In 1995, the costumes were restored in an unknown woman's tomb at the Jeonju Lee's family cemetery in Gapyeong, Gyeonggi-Do, and there are currently nine items remaining. In this study, we first introduced these 9 relics to academia and analyzed the morphological characteristics of the costumes. We also estimated the time and person of burial compared with costumes unearthed from other burials. Jeogories (short jacket) are all four items. One of these items was unusual in shape, and the upper part of the seop (gusset) was wrinkled and shaped. This type of Jeogori appears only till the 1520s in other tombs. There are also two skirts, one of which is characterized by a superimposed pattern. The top and bottom / middle part of the skirt were rolled up, and the skirt, which was double-rolled up in this way, was first discovered. An analysis of the shape of Jeogori and skirt indicated that the person buried in the Jeonju Lee's family tomb was believed to have survived until the early 16th century. Based on these estimated periods, as a result of looking at the genealogy of Jeonju Lee's family, it was concluded that the tomb was probably a woman named Lee Geum Myeong (李金命) born in the mid-15C and died between the late 15C and the early 16C.

제2형 당뇨병 환자에서 적극적 환자 교육이 혈당조절에 미치는 효과

이윤욱,황원선,최선정,이동훈,김도현,이은희,홍은경,노혜림,정윤석,이관우,김현만 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.1

연구배경: 현재까지의 당뇨병 교육에 대한 노력은 제한되었으며, 연구 결과를 보면 식사 조절 교육과 체중 조절 프로그램을 수행한 환자들 중 적극적이고 기간이 긴 교육을 받은 경우, 성공적 결과가 나타남을 알 수 있었다. 자가관리나 체중감량 등의 당뇨병 치료의 중요한 목표는 적극적이고 긴 기간의 교육 없이는 시행되기 어렵다. 본 연구에서는 외래에서 당뇨병 환자를 대상으로 시행할 수 있는 행동 및 식사 교육 등의 적극적 교육 프로그램을 개발하여 제2형 당뇨병 환자들을 대상으로 이들에게 식사 조절 방법에 대한 목표설정과 문제에 직면하였을 때의 해결 방법 등을 교육해서 궁극적으로는 적극적 자아관리에 연결될 수 있도록 도와주는 것을 목적으로 기존의 통상적 교육과 보다 적극적인 교육이 당뇨병 환자의 혈당 조절에 어떠한 영향을 미치는지에 대해 알아보기 위해 다음과 같은 연구를 시행하였다. 방법: 본 연구는 아주대학교 병원 내분비 대사 내과를 처음으로 방문하여 치료받았던 58명의 제2형 당뇨병 환자를 대상으로 하였다. 내원 환자들을 무작위하게 추출하여 진찰권 번호 끝자리에 따라 홀수는 통상적 교육군(conventional education group, CE)과 짝수는 적극적 교육군(intensive education group, IE)으로 나누어 교육하고, 3개월후에 교육의 효과를 평가하였다. 결과: 1) 연구 대상자들의 교육 전과 후의 공복혈당, 식후2시간 혈당 및 HbA_lc 치는 IE군과 CE군 모두 각 그룹 내에서, 유의적으로 감소하였다(p<0.05). IE군에서는 공복혈당이 12.4nmol/L에서 7.7nmol/L로, 식후2시간 혈당이 20.3nmol/L에서 10.9nmol/L으로, HbA_lc치가 9.4%에서 7.0%로 모두 교육 전에 비하여, 교육 후에 감소(p<0.05)하였고, CE군도 공복혈당은 10.9nmol/L에서 9.4nmol/L로, 식후2시간 혈당은 17.1nmol/L에서 14.6nmol/L으로 HbA_lc가 8.5%에서 7.3%으로 모두 교육 후에 감소하였다(p<0.05). 또한, 교육 전에 비하여 교육 후에 공복 혈당 및 HbA_lc치가 감소하는 정도는 IE군에서의 감소가 CE군에 비해 더 현저하였다Op<0.05). 2) 식사에 대한 태도는 3부분으로 나누어 식사에 대한 규칙성, 식사 내용의 균형성, 식사에 대한 태도 등으로 나누어 각각의 점수 및 총점을 비교하였으며 교육 전에 비해 교육 후에 연구 대상자들의 식태도가 향상되었음을 알 수 있었다. 두 그룹간의 차이를 분석한 결과 식사의 균형성 항목에서와 총점에서 유의적으로 두 그룹의 차이를 보여서 IE군에 CE군에 비해 식사의 균형성 측면이 향상되었고, 전체적인 식태도가 좋아졌음을 알 수 있었다(p<0.05). 결론: 비교적 긴 기간은 아니지만 적극적 교육을 받은 당뇨병 환자들이 통상적 교육을 받은 군보다 혈당 및 HbA_lc, 식태도 점수등의 수치의 호전뿐만 아니라 당뇨병 환자의 삶에서 중요한 부분을 차지하는 식사요법 관리 부분에 있어 향상됨을 알 수 있었다. Background: To this date, efforts to develop effective methods for the education of diabetic patients have been limited. The important goal of self-management and weight control for diabetic treatment can not be attained without long and intensive period of education. This study was undertaken to assess the effectiveness of an intensive educational program, of behavior and diet control, which was carried out on subjects with type 2 diabetes, on and out-patient basis. we compared the effectiveness of an intensive education programme with that of a conventional education programme for the self-management of type 2 diabetic patients. Methods: Subjects with type 2 diabetes were randomly selected, and allocated to one of two groups. One group received a conventional education programme of self-management(the CE group), and the second group received an intensive education progammes for three months, after which the effectiveness of the programmes were evaluate. Results: 1) The levels of fasting blood sugar(FBS), postprandial 2 hour blood sugar(PP2h) and HbA1c were significantly lowered in both groups following the intervention(p<0.05). In the IE group, the FBS declined from 12.4nmol/L to 7.7nmol/L, PP2h declined from 20.3nmol/L to 10.9nmol/L, and the HbA_lc showed a similar decline from 9.4 to 7.0% after intervention(p<0.05). In the Ce group, the FBS declined from 10.9 to 9.4nmol/l, the PP2h decreased from 17.1 to 14.6nmol/l, and the HbA_lc also decreased from 8.5 to 7.3% after intervention(p<0.05). The decrease in the FBS and HbA_lc following the educational intervention was more pronounced in the IE group than the CE group(p<0.05). 2) The effectiveness of the education programmes in promoting appropriate dietary behavior in the diabetic subjects was assessed by a scoring system in three parts: a regularity score, a balance score and an attitude score. From a comparative study of the three scores, the patients attitudes were observed to be much improved in both the groups following the intervention compared to before the programmes, but the balance and total scores were significantly higher in the IE group than the CE group(p<0.05). Conclusion: We can conclude that the intensive diabetic education programme is more effective than a conventional programme, not only in improving the patients' levels of glucose, HbA_lc, and dietary score, but also the diabetic patients self-control abilities, promoting behavioral change, and prompting problem solving capabilities in respect to the everyday problems that they have to face throughout their lives(J Kor Soc Endocrinol 18:63∼72, 2003).

한국인에게서 그레이브스병 약물치료의 적정기간

이형숙,이동훈,정희선,이종우,김정은,신승수,정윤석,이관우,김현만 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.1

연구배경: 그레이브스병의 치료에는 항갑상선제, 수술 및 방사성 요오드법이 선택되어 사용되고 있다. 이중 항갑상선제는 가장 많이 선호되고 있으나 낮은 관해율과 높은 재발율로 장기간 치료기간이 요구된다. 저자들은 그레이브스병 환자에게서, 선택되는 치료법의 선호도와 각 치료법의 관해율을 조사하고자 본 연구를 시행하였다. 또한 본 연구에서는 항갑선제 치료의 적정기간을 평가하고자 하였다. 방법: 아주대학교병원에 내원한 환자 중 1년 이상 추적관찰이 가능한 205명의 그레이브스병 환자를 대상으로 조사하였다. 항갑상제군, 수술군 및 방사성 요오드군은 각각 170명, 29명 그리고 6명이었다. ROC curve를 이용하여 약물치료의 예후예측인자를 분석하였다. 결과: 1) 그레이브스병 환자의 치료 방법의 선택은 항갑상선제군, 수술군 및 방사성 요오드군 각각 170명(83.0%), 29명(14.1%) 그리고 6명(2.9%)으로 항갑상선제 치료가 가장 선호되었다. 2) 그레이브스병의 관해율은 항갑상선제군, 수술군 및 방사성 요오드군에서 각각 60.0%(102/170명), 96.5%(28/29명) 그리고 83.0%(5/6명)으로 수술군이 가장 높았다. 3) ROC curve의 AUC는 치료기간과 진단시 TBII가 각각 0.709 및 0.648이었고 적절한 약물투여 추적 관찰기간은 26개월이었다. 결론: 그레이브스병의 일차 치료법으로는 항갑상선제가 선호되고 있으나 수술 및 방사성 요오드 치료군에 비해 상대적으로 낮은 관해율을 보였다. 따라서 항갑상선제 치료로 26개월 이상 관해가 되지 않을 경우에는 치료 방법의 변경을 고려하는 것이 관해율을 높이는데 도움이 될 것으로 생각된다. Background: Graves' disease in an organ specific autoimmune disease. Three kinds of therapeutic modalities (antithyroid drugs, ablation with radioactive iodine and subtotal thyroidectomy) are frequently performed for the management of this disease. The most popular therapeutic policy for the disease in Korea is antithyroid treatment. We analysed and compared the remission rates of all three modalities for Graves' disease, and evaluated the antithyroid modality to determine the correct duration of treatment. Subjects & Methods : The medical records of 205 patients with Graves' disease were reviewed. For the evaluation of the antithyroid modality medical treatment, antithyroid drugs were administered for more than 1 year. The prognostic factors associated with remission were analysed by means of an ROC curve. Results: 1) Of the 205 patients, proportions that received medical therapy, subtotal thyroidectomy and radioiodine therapy were 83.0, 14.1 and 2.9%, respectively. 2) The remission rates of the medical therapy, surgery and radioiodine therapy were 60.0, 96.5 and 83.0%, respectively. 3) The remission rate of the medical therapy was associated with the duration of medication and TBII activity. The determined proper duration for the antithyroid treatment was 26 months from the ROC curve analysis. Conclusion: The above results suggest that the proper duration of antithyroid treatment for Graves' disease is 26 months, after which time the subtotal thyroidectomy or radioiodine therapy should be considered if the disease has not remitted (J Kor Soc Endocrinol 18:24∼31, 2003).

GC-ECD를 이용한 유기염소계 및 Pyrethroid계 농약 동시 분석법

김우성,이선화,김재이,정지윤,이명자,박영채,이영자,정성욱,이봉헌,박흥재 한국환경과학회 2003 한국환경과학회지 Vol.12 No.4

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

본 연구는 96년도에 실시한 우리 나라 중학교 과학 실험·실습 교육의 실태 조사 연구에 따른 계속 연구의 일환으로 고등학교 과학 실험·실습 교육의 실태를 조사하기 위한 것이다. 연구내용은 고등학교 과학 교과서의 분석, 실험·실습 실시 현황 분석, 현행 실험·실습 교육의 문제점 분석, 현행 학교 구성원들의 실험·실습 교육 운영 실태 조사 및 현행 실험·실습 교육의 개선을 위한 연구과제 도출을 주요 연구내용으로 다루었다. 연구방법은 전국의 고등학교 80개교를 대상으로 이들 학교의 학생 1,977명, 교사 165명, 학교장 80명에게 적용하였다. 본 연구에서 밝혀진 결과를 중심으로 우리 나라 고등학교 과학 실험 실습 교육의 정상화를 위한 실험 내적인 연구과제를 제시하면 다음과 같다. (1)교재 개발에 대한 연구, (2)실험 킷트 개발에 대한 연구, (3)교사교육 및 재교육 프로그램 개발에 대한 연구, (4)교실 밖 실험·실습 활동 프로그램 개발에 대한 연구, (5)과학 실험·실습 소재의 개발에 대한 연구. This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et al., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(1997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.
