The experiments were conducted to determine the factors such as light and darkness, phytohormone and seed coat, influencing on seed germination of Bidens tripartita L. and B. frondosa. The seeds of both species were germinated when seed coat was damaged and weakened GA3 and BA stimulated germination of both species but ABA and IAA had no effect on germination of them, which ranged 50.0% to 80.0%. In B. forndosa, when inner layer of seed coat was removed, germination was highly promoted up to 96.7% compared with 10.0% germination rate in another treatments.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

The roles of glycosphingolipids in the proliferation and neural differentiation of mouse embryonic stem cells

Ji-Ung Jung,Kinarm Ko,Dae-Hoon Lee,고기성,장규태,추영국 생화학분자생물학회 2009 Experimental and molecular medicine Vol.41 No.12

Glycosphingolipids including gangliosides play important regulatory roles in cell proliferation and differentiation. UDP-glucose:ceramide glucosyltransferase (Ugcg) catalyze the initial step in glycosphingolipids biosynthesis pathway. In this study, Ugcg expression was reduced to approximately 80% by short hairpin RNAs (shRNAs) to evaluate the roles of glycosphingolipids in proliferation and neural differentiation of mouse embryonic stem cells (mESCs). HPTLC/immunofluorescence analyses of shRNAtransfected mESCs revealed that treatment with Ugcg-shRNA decreased expression of major gangliosides, GM3 and GD3. Furthermore, MTT and Western blot/immunofluorescence analyses demonstrated that inhibition of the Ugcg expression in mESCs resulted in decrease of cell proliferation (P < 0.05) and decrease of activation of the ERK1/2 (P < 0.05), respectively. To further investigate the role of glycosphingolipids in neural differentiation, the embryoid bodies formed from Ugcg-shRNA transfected mESCs were differentiated into neural cells by treatment with retinoic acid. We found that inhibition of Ugcg expression did not affect embryoid body (EB) differentiation, as judged by morphological comparison and expression of early neural precursor cell marker, nestin, in differentiated EBs. However, RT-PCR/immunofluorescence analyses showed that expression of microtubule- associated protein 2 (MAP-2) for neurons and glial fibrillary acidic protein (GFAP) for glial cells was decreased in neural cells differentiated from the shRNA-transfected mESCs. These results suggest that glycosphingolipids are involved in the proliferation of mESCs through ERK1/2 activation, and that glycosphingolipids play roles in differentiation of neural precursor cells derived from mESCs.

Effectiveness of marker-assisted backcrossing breeding for biotic resistance in rice

Jung-Pil Suh,Kshirod K. Jena,Young-Chan Cho,Ji-Ung Jeung,Yong-Jae Won,Im-Soo Choi,Jeom-Ho Lee,Myeong-Ki Kim,Chung-Kon Kim 한국육종학회 2013 한국육종학회 심포지엄 Vol.2013 No.07

The transfer of a biotic resistance gene from indica rice cultivars into japonica cultivars by conventional breeding methods often difficult due to high sterility of the progenies, poor plant type, and linkage drag. Molecular markers provide opportunities to map resistance genes and accelerate the application of marker-assisted backcross(MAB) breeding through the precise transfer of target genomic regions into the recurrent parent. The basis of MAB breeding is to transfer a specific gene/allele of the donor parent into the recurrent parent genome while selecting against donor introgressions across the rest of the genome. The effectiveness of MAB breeding depends on the availability of closely linked DNA markers for the target locus, the size of the population, the number of backcrosses and the position and number of markers for background selection. We have successfully developed Bph18 version of the commercially cultivated japonica elite cultivar by using MAB and incorporating the resistance gene Bph18 that conferred enhanced resistance to BPH. MAB breeding provides a new opportunity for the selective transfer of biotic resistance genes into elite indica rice cultivars devoid of linkage drag. In additon, molecular markers precisely estimate the introgression of chromosome segments from donor parents and can speed up the recipient genome recovery via background selection.

통일교육의 새로운 미국관 정립을 위한 기초연구

정지웅(Ji-Ung Jung) 한국통일교육학회 2023 통일교육연구 Vol.20 No.1

본 논문은 통일교육의 새로운 미국관 정립을 위한 기초연구로 미국의 자국중심적 대한반도 정책이 통일교육에 주는 시사점을 연구해 보았다. 그 결과, 물론 미국은 미래의 통일한국이 미국 영향력 하의 친미적인 국가가 된다면 통일은 반대하지 않을 것이지만 현재, 미국은 떠오르는 중국견제에 몰두하느라 한반도의 평화와 통일에는 관심을 가질 의지가 없다는 것을 우리는 알 수 있다. 따라서 미국의 국가이익과 한국의 국가이익이 엄연하게 다른 현실에서, 아직도 미국의 주장과 압박에 무조건 따라야 하는지 이제는 정말 깊이 생각해 볼 시점이 되었다. 그러므로 통일교육의 내용에 있어서도 우리의 주체적 노력을 담는 내용이 반드시 들어가야 한다고 생각한다. 힘이 없다고 또는 미국이 좋다고 미국의 국가이익을 추구하는 전략에 무조건 추종해서는 남북화해는 물 건너가고 통일은 멀어질 수밖에 없다는 내용이 통일교육에 새롭게 담기기를 희망한다.다시 말하면 어떻게 해서든 남북관계를 풀어서 평화로운 분위기를 한반도에서 형성하고 이를 바탕으로 이곳에서 평화공동체를 주체적으로 만들어 가는 노력을 해야 함을 통일교육 내용에 반드시 다루었으면 하는 것이다. 다만 불필요한 논란을 줄이기 위해 새로운 통일교육의 미국관은 이념적 편향이 아닌 사실에 근거한 팩트를 중심으로 구성되어야 할 것이다. This paper is a basic study to establish a new perspective on the United States. I studied the implications of the U.S. policy on the Korean Peninsula for unification education. Of course, the United States will not oppose unification if a unified Korea in the future becomes a pro-American country under the influence of the United States. However, at present, we can see that the United States has no will to pay attention to peace and reunification on the Korean Peninsula as it is preoccupied with containing the rising China. The Korea’s national interests and the U.S. national interests are sure to be completely different. So it’s time for us to think deeply on whether we should unconditionally comply with the U.S. demands and pressures. Therefore, I argue that the contents of our subjective efforts must be included in the unification education policy. I do not think we should unconditionally follow the States’ strategy that pursue its national interests because we have comparatively little power or because the United States is an ally. If we do so, inter-Korean reconciliation would be getting difficult, and unification inevitably be far away. This is one that the new unification education policy includes. In other words, we should dissolve the inter-Korean relations and create a peaceful atmosphere on the Korean Peninsula. Based on this, we are obliged to create a peace community here. These contents must be included in unification education. However, in order to reduce unnecessary controversy, the new perspective on America in the unification education should be based on facts, not ideological biases.

문화적 관점에서 본 북한체제 지속요인 연구

정지웅(Jung, Ji Ung) 북한학회 2017 북한학보 Vol.42 No.2

본 연구는 김일성 사망이후 끊임없이 제기된 북한붕괴론에 반하여 문화적 관점에서 북한 체제지속요인에 대해 탐구하였다. 즉 “왜 북한 체제가 붕괴되지 않는지?”에 대한 다양한 문화적 접근을 통해 분석하였다. 지금까지 논의된 북한 붕괴론을 유발하였던 다양한 내외적 환경이 있었지만 김정은 정권은 여전히 존재하고 있다. 이 자체가 바로 북한 붕괴론의 한계를 보여 준다고 할 수있을 것이다. 본 연구는 북한체제를 유지시키는 다양한 문화적 요인을 연구하였다. 연구 결과 경제적 어려움에도 불구하고 북한 체제를 떠받치는 문화적 요인이 도사리고 있어서 체제붕괴 가능성은 낮은 것으로 보인다. 북한 체제를 떠받드는 문화적 요인으로는 유교문화의 영향, 정신문화의 영향, 민족주의의 강조, 주체사상의 강조, 통제로 인한 시민사회의 미형성, 감성통제, 그리고 북한자체가 하나의 거대한 종교국가라는 것을 제시하였 다. This paper has attempted to study against the collapse of North Korea since the death of Kim Il Sung. I concentrate on the reason why the North Korea has not collapsed through a variety of cultural approaches. Up to present, there are so many opinions and internal and external environments about the North Korea-collapse-theory, but the Kim Jong-un s regime is still existed. This shows the limits of the North Korea-collapse-theory. This study investigates various cultural factors that maintain the North Korean regime. In this study, I insist that cultural factors keep the North Korea regime as followings; the influence of Confucianism, the influence of mental culture, the emphasis on nationalism and the Juche idea, the absence of civil society, the emotional control, and a giant religious state.

한반도 중립화 통일의 긍정적, 부정적 요인 분석

정지웅 ( Ji Ung Jung ) 북한연구학회 2005 北韓硏究學會報 Vol.9 No.2

This thesis is focused on the negative and positive factors for the neutral unification of the Korean Peninsular. The negative factors of the neutral unification of the Korean Peninsular can be explained as follows. 1. the viewpoint of the U.S. against neutralization of the Korean Peninsular 2. the subjective perception over the possibility of the neutral unification 3. the political situation of Northeast Asia and the standpoint of the great powers, etc. The positive factors of the neutral unification of the Korean Peninsular can be explained as follows. 1. The reconciliation in the inter-Korean relations 2. Eurasia land bridge 3. Switzerland as a neutral state is a case in point 4. neutralization and win-win effect. etc. If we try to acquire the neutral unification of the Korean Peninsular, it would be a breakthrough for the peace of the Korean Peninsular and Northeast Asia.

북한 붕괴론 논쟁 탐구

정지웅 ( Jung Ji Ung ) 서울대학교 통일평화연구원 2017 통일과 평화 Vol.9 No.1

본 연구는 김일성 사망 이후 끊임없이 제기된 북한 붕괴론에 대한 논쟁을 시기별로 탐구하였다. 이를 위해 1) 동구권 붕괴와 김일성 사망, 고난의 행군 시기 이후 2) 김정일 뇌졸중, 그리고 재스민 혁명 이후, 3) 김정일 사망과 김정은의 등장 이후 등으로 나누어 사안별로 북한 붕괴를 주장하는 학자들의 논거와 이에 반론을 펴는 학자들의 주장을 정리하였다. 이어서 북한붕괴론 논쟁을 분석하여 보다 바람직한 통일정책을 펴는 데 일조하고자 하였다. 지금까지 다양한 내외적 환경에 의해 북한 붕괴론이 제기되었음에도 불구하고 김정은 정권은 여전히 존재하고 있다. 이것이야말로 북한 붕괴론의 한계를 보여준다고 할 수 있을 것이다. 이 연구의 결과는 현재로서는 북한의 붕괴 가능성이 낮다는 것을 보여준다. 따라서 앞으로 북한과의 끊임없는 정치 경제적 접촉 및 화해협력과 평화공존 정책을 병행하여 추진할 필요가 있다. 그리하여 과정으로서의 통일을 이루어가는 것이 보다 현실적이라 할 것이다. This paper has attempted to study for debates on the collapse of North Korea since the death of Kim Il Sung. For this, I classified the times as follows : 1) the collapse of Eastern Bloc, the death of Kim Il-sung and the march of hardship 2) the stroke of Kim Jong Il and the Jasmine Revolution 3) the death of Kim Jong-Il and the appearance of Kim Jong Un. Next, I summarized the argument of scholars who had predicted the collapse of the North Korea and scholars who had predicted the preservation of the North Korea. And then, I analyzed the debates on the collapse-theory of the North Korea. As a result of this study, I wanted to serve for the desirable unification policy. Up to present, there are so many opinions of internal and external surroundings about the collapse of North Korea, but the Kim Jong-Un`s regime has been still exited since the death of Kim Jong Il. This shows the limits of the North Korea-collapse-theory. As the result of this study, in the short term, I insist that the possibility of North Korea`s collapse should be low. Therefore, Our Government must pursue not only the unceasing political and economic contacts but also reconciliation and cooperation policy on North Korea. If we propel the unification as the process, this will be more realistic.

김일성 저작집을 통해 본 북한의 기독교 인식과 대응논리 연구

정지웅 ( Jung Ji Ung ) 아세아연합신학대학교 ACTS 신학연구소 2019 ACTS 신학저널 Vol.40 No.-

북한지역의 경우 직접적인 선교는 꿈꾸기 힘든 것이 사실이다. 그러나 이 땅에 내려온 북한이탈주민들을 위한 선교는 상황이 훨씬 좋다. 오늘날 북한이탈주민들에 대한 관심과 선교는 당면과제라 할 수 있다. 그런데 남한에 온 북한이탈주민들은 북한에 있을 때 다양한 경로로 기독교에 대한 부정적 인식을 교육받았다. 그러므로 김일성 교시의 핵심인 김일성 저작집에 나타나는 기독교에 대한 인식은 아직까지도 북한주민들의 기독교에 대한 인식에 가장 중요한 영향을 미친다고 볼 수 있다. 이런 문제의식 하에서 본 연구는 김일성 저작집에서 김일성의 기독교에 대한 인식과 기독교인에 대한 인식 부분만 따로 발췌하여 분석하여 보았다. 왜냐하면 북한에서 김일성의 말은 거역할 수 없는 절대적 훈령이기 때문이다. 연구결과 김일성은 무신론자이며 전쟁 때 잔혹하였던 미국과 기독교를 동일시하였고, 기독교인은 제국주의의 앞잡이, 숭미주의자로 인식하였다. 이 연구는 탈북자들을 만났을 때 그들이 가지고 있는 기독교에 대한 편견을 어떻게 버리게 할지 대응논리를 찾아보았다. 이 연구는 장차 남북교류가 다시 활성화되어 남한의 기독인들이 북한 주민을 접할 때 그들에게 기독교에 대한 올바른 인식을 심어 줄 수 있는 기초자료로서의 의미도 가진다고 할 수 있을 것이다. In North Korea, it is hard for one to even dream of direct missionary work. But the situation for missionary work is much better for the North Korean defectors who have come down to the South Korea. These days, attention and mission to North Korean defectors can be one of the challenges we have faced. However, North Korean defectors who came to the South Korea were educated with the negative perceptions of Christianity through various channels and ways when they were in the North Korea. Therefore, the perceptions of Christianity that appears in the Kim Il Sung Collection, which are the core of Kim Il Sung’s teachings, still have the most important influence on the perceptions of Christianity among North Koreans. Under this awareness of the problem, this study analyzed Kim Il Sung’s perception of Christianity and his perception of Christians separately from his writings. Because Kim Il-sung’s words are absolute commands that can not be disobeyed in the North Korea. As a results of this study, Kim Il Sung was an atheist. And he identified Christianity with the United States, which was brutal during the Korean War. Kim Il Sung recognized Christian as the frontman of imperialism and the worshiper of America. This study considered how North Korean defectors should throw away their prejudices against Christianity. This study can be said to mean that inter-Korean exchanges will be revitalized in the future, giving North Koreans the right data and perceptions of Christianity when we encounter them.
