Background: The smoking rate of adult male is 68.2% in Korea and that of adolescent and women has risen recentlyMinistry of Health and Welfare plans to raise the price of cigarettes by 1,000 Won per pack this year in hopes of securing funds to aid the underprivileged and discourage excessive smoking. . In this study, we tried to find the relationship between tobacco price increase and willingness to quit smoking among university students, and the factors associated with willingness to quit smoking. Method: The data were collected by questionnaire survey from 225 university students living in Seoul. The questionnaire contained items on age, sex, smoking history, economical status and the intention to quit smoking when the tobacco price be raised. Result: The proportion of smokers who has the intention to quit smoking if the price of tobacco be raised by 3,000 Won was 46.2%. The factors associated with willingness to quit smoking were age of initiating smoking, opinion for price of cigarette, self efficacy scores, current plans to quit smoking, and viewpoint of changes in the rate of smokers. Conclusion: The results showed that tobacco price rises will increase willingness to quit smoking among university students.

Objectives : In this study, we classified the anatomical correlation of the facial nerve, vestibular nerve, and cochlear nerve along different locations of the internal auditory canal and analyzed the clinical outcome of hearing preservation surgery of vestibular schwannoma through the middle cranial fossa approach performed based on the anatomical study results. Methods : Cadaveric temporal bone dissection of 58 Koreans was performed and each nerve distribution pattern along the segment from the brainstem to the base of internal auditory canal was classified and schematized. Clinical application results were obtained from medical records of 14 patients who were diagnosed of tumor originating from the internal auditory canal and received mass excision via extended middle cranial fossa approach. Results : The cochlear nerve and vestibular nerve could be separated at porus of the internal auditory canal in only about 6% of our materials, but we could identify the facial nerve, vestibular nerve complex and cochlear nerve individually at the midportion in about 88%. Hearing preservation, which was achieved in 10 of 14 patients was more feasible when the tumor was of superior vestibular nerve origin with medial location in the internal auditory canal and when the patient had better preoperative hearing. Conclusion : Applying the above mentioned topographic anatomical information to the extended midcranial fossa approach, the vestibular nerve and the cochlear nerve could be separated by initiating the dissection at the mid-portion after exposing the internal auditory canal and consequently achieve favorable results of functional preservation including hearing.

The allusion is divided into trope[比] and treating precedent[用事] in Jiaoran’s Statutes of Poetry[詩式]. In this study we found that the allusion would be a trope when there is a corresponding relationship between the allusion and the poetic self, and it would be a treating precedent when there is only an allusion enumerated in a poetry. The allusion as a trope is classified into metaphor and metonymy. The conceptual metaphor “One’s behavior is a behavior of the great names in the past.” and the conceptual metonymy “A person replaces the group he belongs to.”, “The music player replaces his instrument.” are used as tropes in the poetry. Findings in this study are expected to be the key standard for understanding the classification of poetry in Statutes of Poetry.

기존에는 주남 토저 각 장의 전반부를 씩씩한 무사가 토끼그물 치는 모습으로 풀이해왔으나 해석에 어색한 점이 있었다. 본고는 이 부분을 덩굴식물의 무성한 모습으로써 무사와 공후의 긴밀한 관계를 비유한 것으로 보았다. 그 근거로 첫째, “施于○○”는 《詩經》에 반복되는 정형구로 덩굴식물이 어딘가에 뻗은 모습이다. 이들은 모두 부모자식, 형제, 부부, 군신 간의 사랑을 나타내는 이동의 모티프이다. 둘째, “兎?”는 상고음에서 魚部에 속하는 첩운으로 女蘿라는 식물을 가리키는 연면사이다. 이들 근거에 따라 제1장 전반부 역시 우거진 덩굴식물을 획득하는 모습으로 해석되며, 이 역시 《詩經》에서 사랑을 비유하는 데에 흔히 쓰이는 모티프이다. The existing readings of “Tuju(兎?)” were unnatural because they considered the first halves of each stanza as the scene of a net for catching rabbits cast by brave soldiers. Whereas we will see these parts would be metaphors of the relationship between the soldiers and feudal lords, using the image of vines and trees ensnarled together. The phrase “施于OO” is a kind of formulaic expressions which means a vine led to somewhere. It is repeated in Shijing several times and it is a motif presenting affection between parents and offspring, siblings, spouses, and sovereign and subjects. The word “兎?” is a recurring rhymes of the 魚 Yu group, and it is a linked word which means a vine called “女蘿”. The first half of the first stanza is a scene of gathering flourishing vines, and it is a kind of motifs used for the metaphor of affection frequently in Shijing.

In this study, the probability of plaque rupture was considered in terms of peak radial stress and peak radial stress gradient. In particular, when the peak radial stress gradient was considered, it was possible to explain phenomena that cannot be explained by conventional stress alone, including the rupture of caps > 65 μm and the occurrence of rupture at stress distributions < 300 kPa (the critical rupture stress). A numerical simulation using idealized plaque of each type and mechanical behavior analysis demonstrated that plaque rupture is affected by plaque type. It can be concluded that a higher probability of rupture can be expected when high stress and a high negative stress gradient occur near a thin fibrous cap.

To understand the mechanism of the development of pressure ulcer, it is important to know contact pressure between human body and mattress. In this study, we generated simplified finite element model of human. We also generated a diversity of shape and material with FE model of mattress, and then we performed numerical analysis in contact condition. In this result, we found correlation between several condition of mattress and contact pressure in FE model of human.

레이저 직접적층법 및 선택적 레이저 용융법이라 불리우는 금속적층제조 공정은 금속 원소재를 고에너지 빔으로 녹여서 한층 한층 쌓는 과정을 반복하여 3 차원의 복잡한 형상을 제조할 수 있는 새로운 공정으로, 일반적인 가공법으로는 제작하기 힘든 중공 형태 등의 아주 복잡한 형상을 쉽게 제작할 수 있는 큰 장점이 있어서 다양한 산업분야로의 응용이 기대되고 있다. 금속적층제조에는 크게 와이어 아크 적층방식, 고에너지 직접적층방식 및 레이저 파우더 베트 용융 방식의, 세 가지 방식의 공정이 널리 응용되고 있는데, 이 중 와이어 아크를 제외한 다른 두 가지 방식은 고에너지 레이저 빔을 응용하여 금속 분말을 용해하여 쌓는 공정이다. 구체적으로 레이저 직접적층법은 금속 대상재에 직접 분말형태의 원소재를 순차적으로 고출력 레이저와 함께 분사함으로써 용융풀을 형성하고, 이를 반복하여 층층히 적층하는 공정으로, 사용자가 원하는 부분에 선택적인 적층이 가능하고 복잡한 형상의 표면에도 적용이 가능한 등의 장점이 있어서 앞으로 기계부품의 표면강화나 보수에 널리 활용될 것으로 기대된다. 선택적 레이저 용융법은 분말재료를 한층 한층 미리 깔아놓은 후 레이저를 조사하는 과정을 반복하여 적층하는 공정으로, 아주 정밀한 3 차원의 형상이 제작 가능하며 중공 형태 역시 제작이 가능하기 때문에 맞춤형 기계부품이나 내부유로를 가지는 복잡한 형상, 격자 구조 등 다양한 고부가가치 부품에 향후 적용이 기대되고 있다. 본 발표에서는 극저온 분야 등 다양한 극한 환경에 앞으로 적용이 기대되고 있는 금속 적층 관련 연구결과들과 최근 산업적용사례들을 적층소재의 재료물성 관점에서 소개하고 향후 극복해야 할 과제들을 논의해 보고자 한다.
