On the framework of a linearly perturbed Friedmann-Robertson-Walker spacetime, we derive an expression for the cosmological angular diameter distance affected by scalar and tensor perturbations. Our expression is applicable in linear order to distances in general FRW models. We study the effect of a stocastic gravitaional wave background on the two-point correlation function of the angular diameter distance fluctuations and, on the basis of this we also derive an expression for the power spectrum of the angular diameter distance fluctuations.
As long as we know, Paul was one of the greatest missionaries throughout the whole Christian history. In the short period of around 10 years he planted a lot of independent churches in major cities of Eastern part of Rome, and challenged the churches to continue to spread the gospels to their neighbors. As a result of this, when he wrote the letter to the Romans, he was able to write ‘But now that there is no more place for me to work in these region, (Rom. 15:23). Through this saying, we can easily guess that his ministry was so effective and fruitfu l. However, this does not mean that his ministry was always smooth and mild. Rather, as we all know well, there were numerous difficulties and hardships in his ministry. The tria1s were so tough that he could not but confess that “We were under great pressure, far beyond our ability to endure, so that we despaired even of life"(2 Co 1:8). Yet he was not subdued by a11 the pressures. Rather he overcame all these difficulties and fulfilled his ministry successfully, saying “We are hard pressed on every side, but not crushed; perplexed, but not in despair, persecuted, but not abandoned; struck down, but not destroyed"(2 Co. 4:8- 9). He carried out his ministry with full of hope in that worst situation. What were then the roots of the hope he had which were the major motivation of his fruitful ministry? 1 looked for six major roots of the hope he had in this paper. The first one was the strong affirmation that he was called to become the apostle for the gentiles. Since he strongly believed that he was called by the Lord of the universe, he was sure that the Lord would fulfill his ministry through him under any situation. The second factor was the conviction about the reward that would be given to him, a faithful missionary, in the coming world. The third one was the belief in the guidance and empowerment of the Holy Spirit in his ministry. The forth one was his strong love for the souls. His love for souls was so strong that nothing could subdue his zea1 for winning souls. Fifthly, he was well aware that he got too great grace to pay back to Jesus. This awareness of the limitless grace always caused him to dedicate his whole life for mission. Finally, the eschatological faith also was a major source of his endless hope. To his belief the last time would be the time of perfect victory of Lord Jesus and his people. Believing the final triumph, he was not in low spirits in spite of all the present failures and difficulties. Also in expecting the great time, spreading the gospel was the best way to shorten the time of Jesus' coming back. As Paul' s ministry situation was not easy at all, so are the circumstances of today’s mission fields. In this situation, one the most urgent matters all God’s workers need to consider is the way of being empowered. Since the roots of hope that empowered Paul are still valid for today’ s missionaries, 1 hope, this paper would cause us to check the roots of our hope whether they are right and strong enough.
탄소 섬유강화 에폭시기지 복합재의 경면 가공한 스테인레스 강 상대재와 마찰과 마모에 바탕을 둔 연구에서 다음과 같은 결론을 얻었다. (1) 일방향 탄소섬유 강화 복합재의 마모 거동에 미치는 미끄럼 방향의 효과는 다르며 작용하는 마모 메커니즘의 형태에 의존한다. (2) 상온에서 경면 가공한 스테인리스 스틸에 대하여 미끄럼이 일어나면 AP 방향에서 높은 마모 저항과 낮은 마찰계수가 관찰되었다. (3) 복합재의 비마모율은 미끄럼 속도가 증가하면 N방향과 P방향에서는 감소하는 경향을 보이며, AP 방향에서는 증가하다가 감소한다. 이것은 마모 메카니즘의 영향으로 속도가 증가하면 마모 이착막의 생성이 빨라져 이착막 속의 탄소섬유가 윤활제의 역할을 하기 때문이다. (4) 복합재의 마찰계수는 미끄럼 속도가 증가하면 3방향 모두 증가하다가 일정한 값에 수렴하면 N방향이 가장 크며, P방향과 AP방향 순이다. 이는 N방향에서 마찰초반에 발생한 섬유의 쟁기질에 의한 상대재 표면의 손상과 돌기변형에 따른 것이며, AP방향의 마찰계수가 가장 낮다.
본 논문에서는 토목 구조물에 대한 바람의 영향을 알아보기 위하여 수치 기법으로 해석하였다. 지간이 긴 현수교는 바람에 의한 공력탄성학적 분안정성에 놓일 수 있으므로, 설계 시 공기력은 주요한 고려사항이며 공탄성 안정성은 반드시 확인되어야 한다. 풍속이 임계 플러터 속도를 넘어서면, 교량 구조물은 바람과 상호작용에 의한 플러터 현상으로 인해 붕괴된다. 교량 단면의 공탄성 해석을 위해 전산유체역학과 전산구조해석을 이용하였으며, Navier-Stokes방정식을 사용하여 공기력을 구하였다. 본 연구에서는 구조 강성에 따른 교량 구조물의 임계 플러터 속도가 연구된다. 교량 단면의 임계 플러터 속도는 구조강성의 변화에 민감함을 확인할 수 있었다.
This study is on the changing pattern of fish-and-shellfish uses during the last two thirds of Chosun period on the premise that they are influenced by development of fishing technology. With a literary approach, this paper researches how fish-and-shellfish production and consumption pattern changed, especially in relation to technological development of fisheries. First, we examine into the changes of fishery production. And next, we analyze the kind and cooking method of fish-and-shellfish in [Eum-sik-di-mi-bang](1670) and [Gyu-hap-chong-seo](1815). The analysis of two books revealed that there were significant differences in fish-and-shellfish uses. Because the two books were written with a gap of 145 years and the development of fishing technology and remarkable changes of fishery production affected on the fish-and-shellfish uses. Due to primitive fishing tools and skills, fresh-water and reverse-river-fish and shellfish had been caught in substantial amount until the middle ages of Chosun period. As a result, the availability of seafood were limited extremely even in the upper classes. These situations are evidenced by the analysis of [Eum-sik-di-mi-bang]. Only 12 kinds of fish-and-shellfish are described in [Eum-sik-di-mi-bang]. Most of the sesfoods is mollusc which is easy to catch. As for the salt-water fish, dried cod and dried herring were mentioned. Mullet, the reverse-water-fish, is used most frequently. Only one kind of 'Hoe', which needs extreme freshness, is described. This means that the use of fresh fish-and-shellfish was very limited to some kinds which could be caught near the village. As the netting fishery began to be developed in the 18th century, the production of some salt-water fishes, such as anchovy, shrimp, yellow corvina, pollack, and herring, had increased remarkably to make marine resources more available. Small fish, such as anchovy and shrimp were preserved as 'Jeot-gal' and sold nationwide. Therefore, 'Jeot-gal' and seafood could be used in Kimchi around this time and had a deep influence on the change of Kimchi in taste and nutrition. In [Gyu-hap-chong-seo], 33 kinds of fish-and-shellfish are described. Including cod and herring, 17 kinds of sea water fish and mollusc are mentioned. Some of these are consumed in fresh state, neither as dried nor as salted. Because the merchants promoted the transport of seafoods to other regions according to the growth of commercial economy. As a result the diet of the people could be enriched by the various seafoods.
This paper is an attempt to practice Jungian ways into a great poem of Yeats’s, “Among School Children,” over which home and foreign academic societies concerned have been under much controversy till now. But it is very regrettable that I have no belief if the views issued from some noted scholars in the societies have been plausible or appropriate. In the sense, as suggested by the title, the encounter between Great psychologist C. G. Jung and Great poet W. B. Yeat is very significant in that they both had pursued the same ultimate subject as a supreme state of humanity respectively represented as archetype of ‘Self’ and ‘Unity of Being.’ For Jungian ways applied to the poem, first symbols, images and psychological situations lurking in it can be useful as the interpretative clues. These representations can function as faithful agents helping us to reach the gate of the poetic truth, urging us to mobilize Jungian esoteric terms corresponded to several kinds of psychological situations people must go through. ‘Great Mother,’ maternal archetype, who stands for earth and womb and takes two characteristics, construction and destruction, possessing opposite qualities of Witch Kali and Virgin Mary, exercises serious effect upon a male child as an earthly hero. Some ideal aim or mission that the hero strives to grasp is just equivalent to hurriedly return to the womb as his biological origin, namely secular realization of the principle of ‘entrophy’ meaning the second principle of thermodynamics; does mean the hero’s life whatever else? It can be associated with the biblical situation, Pieta, the holy picture describing Mary’s lamenting in bitter grief with embracing his dead son, Jesus Christ. In fact, the hero is determined to death resulting from energetic emission of burning libido, which can be embellished with either establishment of duty or sacrifice to community. Thus, ‘Great mother’ longing for the runaway baby from her womb, in turn, is expecting his death to suffice emptiness of womb and heal her chronic complex, hysteria. In conclusion, in the poem, we can find that the destiny that after “children” in the “school” go through a initial step of ‘individuation,’ the perfect state which further can be indivisible, they, absurd beings, are cast into the tough world with each secular mission is just to aid the scheme of ‘Great Mother.’ “school” is a temple teaching “dance” and “children” in it dancers learning “dance.” Accordingly, the enigmatic relation of “dancer” and “dance” in the eighth stanza would be unraveled: The former can come under an archetypal pattern and the latter can correspond to its practitioner. Thus, “dance,” playing a role of ‘complex’ as compelling force and driving us to imitate it, tires us, dancers, finally to death, as an erotic dancer Salome’s dance murdered a spiritual dancer John the Baptist. After all, we can never get to the core of “dance” only to hang around its brink, which Yeats should know. As usual, getting captivated by “dance,” we continually shout hoarse to others: Shall we dance?
