준고냉지 스타티스(Limonium)의 개화조절 및 화수의 선단고사에 관한 연구
Ⅰ. Effects of final time of flower stalk removal and initial the number of flower stalk on yield and harvest time To delay the harvesting time of perennial statice ‘Ocean Blue’ to the autumn, flower stalk of the seedlings propagated by root cutting were removed at intervals after transplanted on 20 May. The stalk removal continued until 10 July (SR1), 20 July (SR2), 10 August (SR3), or 20 August (SR4). Also the untouched stalk was included as a control. The time taken from flower stalk removal to the flowering was 84 days for control, 45 and 49 days in SR1 and SR2, and 55 and 66 days for SR3 and SR4, respectively. The time of harvest was during August~September for control, during September~October for SR1 and SR2, during October~November for SR3, and during November for SR4. Total yield was highest in SR1 (2,894 bundles per 10a), compared to 2,617 bundles in control. In general, yield was decreased when stalk removal was delayed. We also controlled the number of flower stalk when the plants harvested and cold-stored in late December were replanted in the field, in order to investigate its effect on harvest time and yield. The number of flower stalks was adjusted to 3 (FS3), 5 (FS5), and 7 (FS7), with the rest of them all removed. No removal treatment was included as a control. The results showed that the number of newly bolted flower stalk was highest (4.1~4.8 per plant) in FS3 and FS5 harvest time, while the control had only 0.3 per plant. The time of harvest was both June and August~September for FS3, June~September for FS5, June~August for FS7, and June~August for control. Yield was highest in FS5 (6,006 per 10a) and lowest in FS3. Ⅱ. Effect of planting time on flowering and cut-flower quality of perennial statice plants in sub-alpine region The first experiment used two-year old ‘Ocean Blue’ statice plants harvested in early December and cold stored until transplanted in the greenhouse in different times: 1 March, 20 March, 10 April and 1 May. The purpose of using old plants was to save the cost of plant material for production in sub-alpine region. There was no effect of planting time on growth of two-year old plants. The weight and total yield of cut flowers were highest when planted on 20 March, while ones planted on 10 April and 1 May showed lower flower weight and yield. The days taken from planting to flowering were 110, 95, 85 and 77 when planted on 1 March, 20 March, 10 April, and 1 May, respectively. The best time of harvest varied according to the planting time: June~July for the plants transplanted on 1 March, June~August for ones on 20 March, July~August for ones on 10 April, and July~September for ones on 1 May. The second experiment was to determine the effect of planting time on growth and flower quality of two cultivars of Limonium sinensis ‘Yellow’ and ‘Silver’. The planting time for both cultivars was on 1 April, 20 April, 10 May and 30 May. For ‘Yellow’, growth was best when planted on 30 May, in terms of leaf width and length and plant width. The times of flowering were 5 July, 15 July, 3 August, and 24 August when planted on 1 April, 20 April, 10 May and 30 May, respectively. The yield of cut-flower, which generally increased with earlier planting, was highest when planted on 1 April (5,404 bundles per 10a). All the plants bolted regardless of planting time. For ‘Silver’, plants flowered on 7 July, 17 July, 7 August, and 27 August when planted on 1 April, 20 April, 10 May, and 30 May, respectively. The yield was highest in the plants transplanted on 1 April(4,820 bundles per 10a), while lowest when planted on 30 May, which was related with the lowest bolting rate (less than 30%). Ⅲ. Effect of low temperature and GA3 on growth and flowering of statice This chapter consisted of three experiments. The first experiment was to determine the effect of chilling periods and planting time on yield and flower quality of perennial statice ‘Ocean Blue’. The root cutting-induced seedlings were chilled at 2°C for 30 or 60 days before transplanted on 20 June or 1 July. Non-chilled control was also included in the treatments. The yield was 2,114 and 1,633 (bundles per 10a) in the plants transplanted on 20 June after chilled for 30 and 60 days, respectively, compared to 1,531 in their corresponding non-chilling control, while it was 1,706 and 1,414 in the plants transplanted on 1 July after chilled for 30 and 60 days, respectively, compared to 1,283 in their corresponding control. The chilling period and planting time had no effect on flower quality. The second experiment was to determine the effect of chilling periods and GA3 on flowering time and yield of perennial statice ‘Misty Blue’ plants propagated by tissue culture. The seedlings were chilled at 2°C for 0, 2 and 4 weeks and all transplanted on 1 April. One week later, GA3 was applied at 0, 200 and 400 ㎎·L^(-1). The chilling periods and GA3 had no effect on growth and flower quality. The best treatment in terms of advanced flowering (10 days) and increased yield (39%) was when treated with only GA3 at 400 ㎎·L^(-1). The third experiment was to determine the effect of chilling periods on flowering time and yield of annual statice ‘Deep Blue’. The seedlings were chilled at 2°C for 0, 20, 30 and 40 days and all transplanted on 10 May. Time of flowering was advanced in the plants chilled for 30 and 40 days to the similar extent (20 days compared to non-chilled control). However, 40 days of chilling treatment caused 16.5% of the seedlings to die. The yield, determined in July, was highest in the 30 days of chilling treatment (8.5 times the yield of control). Many of non-chilled control plants failed to bolt. Ⅳ. Relationship between mineral nutrients and dieback of flower spike of statice The first experiment was to determine the relationship between mineral nutrients and dieback of flower spike of perennial statice ‘Ocean Blue’ plants treated Yamazaki solution supplemented with Ca and B. Calcium rates were at 0, 3, 6 and 12 ㎎·L^(-1) and B rates were 0, 0.02, 0.05 and 0.08 ㎎·L^(-1). The results showed that tissue Ca and B contents showed a significant relationship with dieback of flower spike. Flower Ca content was 0.24% when treated with Ca at 6 ·L^(-1), where dieback was low. Flower boron content was 61.5 ㎎·㎏(-1) when treated with 0.05 ㎎·L^(-1), where dieback occurred very minimally. The second experiment was to determine the effect of soil moisture on the occurrence of dieback of flower spike the perennial statice ‘Ocean Blue’. The plants were irrigated at 1, 2, 3, 5 and 15 day-intervals each at 200 ㎖ per plant. Soil moisture contents averaged to be 28.4, 23.8, 24.6, 24.1 and 11.5% for the corresponding irrigation intervals. The occurrence of dieback on the flower spike was serious especially when irrigated at 1 and 15 day-intervals. We analyzed mineral nutrient contents in flower tissues (including spike and stalk) 15, 25 and 35 days after bolting, each month from May to September. The data on nutrients were analyzed to determine the relationship with dieback occurrence. Tissue N was most abundant throughout the whole period, followed by K. Younger flowers contained higher contents of N, P and K than old flowers. Flower B content was highest in May and lowest in June and August regardless of flower maturity. Mature flowers had higher B contents than younger flowers especially in May, June and September. However, this trend was reversed during July and August. The healthy flowers contained twice as much B as ones with dieback. The spray treatment with 0.2% Na₂B₄O_(7)·10H₂O, 60 and 120 days after planting, or soil treatment with H₃BO₃ at 0.4 ㎏ per 10a before planting, both proved to be effective in controlling the symptoms of dieback on the flower spike of perennials statice.

The four powerful countries around North-East Asia have the same interests in giving prioity to their domestic problems and wishing a maintenance of the status quo and a permanent peace on the Korean Peninsula. South Korea aims at a political stability and to gain an international high rank. North Korea seems to accept a multipartite conference for peace on the Korean peninsula and the four powerful countries acceptance of the present state of two Korea. It seems that the crossrecognition of two Koreas becomes unqustionable. But to solve the problems between two Korea should not be controlled by the surrounding four powerful countries. Two Korea themselves have to solve the problems of disarmament, peace and unification positively and actively because the surrounding countries can only take a negative cooperative attitude on this matter. If the security in North-East Asia is to be formed on the foundation of cooperative system between America and Japan, South Korea needs a close political, economic coperation with Japan. The relation of South Korea to China also has to be established after a due consideration about the prospects political and economic between two countries, keeping in mind the lesson learned in the course of developing relationship with Russia. Since the United States currently enjoys political hegemony over Northeast Asian security matters, it will try to maintain the present structure without relinquishing its vested interests. China, to prevent American hegemony and Japan, in seeking political influence commensurate with economic power have reasons for a positive response. At present, Russia, which is trying to restore its power status in the region, is the only major power explicitly committed. In so far as the United States is lukewarm, rapid progress cannot be promised. Therefore, a proper strategy for South Korea seems to be maintain the basic security tie with the United States and to search prudently for the multilateral possibility within the limits of this tie. In the case of the Korean Penisula, which is still divided into South Korea and North Korea, a special character of their own system is reflected in the two Koreas' unification policy. Both sides initially offered exchange to each other. But in the mid-70s as South Korea took the upper hand in power over North Korea, their unification policy also began to change. In the light of the correlation between a power-related situation and both countries' unification policy, one which has stronget power than the other is vigorously inclined to take an aggressive and positive unification policy including a variety of exchanges, especially in economy, while the other, which has the weaker power is shown as avoiding and passive towards the unification policy. It is a special point that Seoul and Pyoung-yang all have used their own unification policy as leverage for their domestic political game.

무엇보다도 이 작업은 '하나님의 말씀'이 이루시는 사역의 일부임을 알아야 할 것이다. 이제까지 우리느 ㄴ롬3:21-31의 말씀을 인간에게 유익한 쪽으로만 보아왔다. 그것은 '이신칭의' 교리로서나 '구원'이나 '은혜'로 보거나, 혹은 '복음'으로만 보아온 것이다. 그것은 죄로 부패한 인간 본성의 이기적인 속성에서 나온 것으로 보아야 할 것이다. 그러나 본 논문은 본문(롬3:21-31)이 하나님의 의를 드러내는 것이 중심의미이며, 바울은 이 복음을 통하여 '하나님의 공의'를 드러내는 데에 초점을 맞추었다는 것을 논증한 것이다. 믿음으로 말미암아 하나님으로부터 인간에게 주어지는 '인간의 의'는 하나님의 공의에 비하면 부수적인 것에 지나지 않는다. 본 논의는 서론에서 필요성을 제시하고, II장에서 루터와 칼빈의 주석에 나타난 오류를 지적하였다. III장에서는 정확한 본문 주석을 ㅜ이한 배경으로바울과 로마 교회의 상황, 그리고 로마서의 주제와 본문의 텍스트 속에서의 의미를 궁구하였다. 그리고 IV장에서는 II, III장의 논의를 배경으로 올바른 주석을 새로이 행하였다. 그리고 그것을 바탕으로 결론을 도출하였다. 본 논의는 '이신칭의' 교리를 하나님과 인간 사이의 언역으로 보고, 그것을 언약의 주체자인 하나님과 인간 사이에 공평하게 법정적 의미로 해석한 것이다. 루터나 칼빈이 행한 주석은 모두 로만 카토릭과의 대치상황에 이끌린 해석이므로 그 한계를 지적하고 그 이후의 주석자들에게 미친 신학적 문제들을 시정하려고 논의를 전개한 것이다. 이 연구를 통하여 로마서를 저술한 바울의 관심이 '복음'으로서 '하나님의 공의'를 드러내려 하였다는 것을 입증하였다. 로마서를 신약의 실질적 교리서로 보고, 이 교리를 통하여 구원과 심판이 이루어진다는 점을 감안하여 객관적이고 공정하게 해석해야 한다는 점에 착안하였다. 본 논문은 로마서 중에서도 본문(롬3:21-31)이 교리의 가장 중핵적인 부분이므로, 이를 객관적이고 축자적(逐字的)으로 주석적 연구를 수행하였으며, 그 결과, 바울이 본문(롬3:21-31)에서 '하나님의 공의'를 최우선으로 드러내려 하였음을 입증한 것이다. First of all, We must understand that the work about confirmation of God's justice belongs to the work of 'The Word'. Until now, we have considered Rome 3:21-31 as being profitable for humans. It has been looked upon as a doctrine 'justification by the faith', salvation or the Gospel. It dates from selfish attribute of human nature. The main meaning of the text, however, is to reveal God's justice and Paul demonstrated that his Gospel had focused on revealing God's righteousness. Human's righteousness given by God is no more than incidents. This argument regards doctrine 'justification by faith' as the promise between God and human and interprets it impartially between God, the subject of appointments and humans. Luther's or Calvin's notes all point out the limit of interpretation guided to holding out against Roman Catholic and argue to correct various theological problems affected by the next theologian's wrong annotation tendency. I proved Rome's writer, Paul's interest had tried to reveal God's justice through the Gospel in this study. I regarded Rome as a dogma of The New Testament and took note that this dogma had to be defined objectively and fairly, considering that salvation and judgement are carried out through this dogma. This thesis conducted annotated researches as Rome 3:21-31 is the most important part. As a result, I proved that Paul had tried to reveal God's Justice with first priority in the text(Rome 3:21-31).
