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.

공기업의 윤리경영이 조직유효성에 미치는 영향에 관한 연구

이욱진(Lee, Wook Jin),조동혁(Jo, Dong Hyuk) 글로벌경영학회 2019 글로벌경영학회지 Vol.16 No.2

최근 들어 기업의 윤리경영활동은 생산성 향상, 기업이미지 제고, 투명성 강화, 지배구조의 건전성, 사회공헌, 고객만족 등에 있어 긍정적인 영향을 미침에 따라 기업의 생존을 위한 필수가치 이자 지속가능한 발전을 위한 핵심요소로 인식되고 있다. 따라서 본 연구는 기업의 윤리경영활동이 조직성과에 미치는 영향을 연구하기 위해 문헌고찰을 통하여 윤리경영활동(윤리방침, 윤리시스템, 윤리문화)이 조직유효성(조직몰입, 조직시민행동)에 미치는 영향과 이러한 영향 관계에서 조직동일시의 조절적 영향을 실증적으로 검증하였다. 연구결과, 첫째, 윤리경영활동의 하위요소인 윤리방침, 윤리시스템 및 윤리문화는 모두 조직몰입에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 윤리문화는 조직시민행동에 긍정적인 영향을 미치는 것으로 나타났다. 셋째, 조직몰입은 조직시민행동에 긍정적인 영향을 미치는 것으로 나타났다. 마지막으로 윤리시스템 및 윤리문화와 조직시민행동 간의 관계에서 조직동일시는 조절적인 영향을 미치는 것으로 나타났다. 오늘날 윤리경영활동은 기업의 경쟁력 강화를 위한 선택이 아닌 필수적인 요소로서, 윤리경영 체계를 구축하지 않은 기업은 조직의 성공뿐만 아니라 지속가능한 발전이 불가능하다. 따라서 본 연구를 통하여 기업의 경쟁력 확보와 지속 가능한 발전을 위한 윤리경영활동의 중요성을 다시 한 번 인식시키고, 윤리경영 실천을 위한 전략적인 방향성을 제시하였다는 점을 본 연구의 이론적 및 실무적 의의라 할 수 있다. Recently, ethics management has a positive impact on productivity improvement, corporate awareness, enhanced transparency, soundness of governance, social contribution, and customer satisfaction, and is recognized as a must for the survival of companies. Therefore, this study empirically verified the effect of ethical management (ethics policy, ethics system, ethics culture) on organizational efficacy (organizational commitment, organizational citizenship behavior) through literature review to study the effect of ethical management activities on organizational performance and the moderating effect of organizational identification in relation to the relationship between them. Results, First, ethics policy, ethics system and ethics culture have a positive effect on organizational commitment. Second, ethics culture has a positive effect on organizational citizenship behavior. Third, organizational commitment has a positive effect on organizational citizenship behavior. Finally, organizational identification has a moderating effect on the relationship between ethical system and ethical culture and organizational citizenship behavior. Today, ethical management activities are an essential element, not an option, to enhance a company s competitiveness. Thus, a company that has not established an ethics management system is unable to make sustainable development as well as the success of the organization. Therefore, the theoretical and practical significance of this research is that the research once again recognized the importance of ethical management activities for securing competitiveness and sustainable management of the company, and presented strategic direction for implementing ethical management.

This paper presents a novel method to detect the rotor position of the BrushLess DC(BLDC) motor at standstill and a start-up method to accelerate the rotor up to a certain speed where the conventional position sensorless control methods based on the back EMF could work reasonably. The proposed initial rotor position estimation method is suitable to avoid the temporary reverse rotation or the starting failure. This method can be implemented using only one current sensor at DC link of the inverter. It does not depend on the model of the motor , and it is robust to motor parameter variations. By the proposed method, it is demonstrated experimentally that a stable starting can be achieved even with severe mechanical disturbance.

친족에서 정적까지 ― 『시경(詩經)』 ‘붕우(朋友)’의 성격

이욱진 ( Lee Ukjin ) 한국중국학회 2021 중국학보 Vol.98 No.-

본고는 시경의 ‘朋友’ 관련 표현이 본래 동족 친척의 뜻이었음을 밝히고, 작품별 쓰임새를 분석하여 당시 군자 계층의 사회 구조를 설명하기 위해 작성되었다. 서주에서 춘추시대 초기에 이르기까지 문헌의 용례를 보면 붕우는 귀족의 일가 친족이라는 뜻으로 쓰였다. 붕우는 형제, 자손, 인척 등과 병칭되어 맥락에 따라 형제와 친척을 포괄한다. 시경에서 붕우 관련 칭호는 제례, 혼례, 군사 및 정치 갈등을 주제로 한 시에 쓰인다. 주대에 제사는 조상이 같은 후손들이 모여 복을 비는 의례였으므로 임금과 신하 간에도 종법 질서가 적용되었다. 따라서 붕우는 종실의 일족으로 보는 것이 더 정확하다. 제사를 마친 뒤에는 으레 연회가 벌어졌고, 이는 종족 구성원이 우의로써 화합하는 자리였다. 주대의 봉건제는 친족을 각지에 제후로 봉함으로써 왕실에 대한 군사적 위협을 막아내는 것이 주된 기능 중 하나였다. 험윤의 침입을 막아낸 공적을 칭송한 시에서 붕우를 대접하는 내용은 바로 왕실을 구해낸 친족을 위로한 것이다. 붕우는 혈연적으로 같은 종실의 친족이었지만, 정치적으로는 같은 임금을 모시는 동료 신하이기도 했다. 시경에는 우의가 두터워야 할 친족이 자신에게 일을 떠넘기며 심지어 모함하여 해치려 드는 세태를 원망하는 내용이 자주 등장한다. 여러 작품에서 같은 시상 전개를 보이고 있는 점을 감안하면 붕우는 이미 뜻을 함께하는 동료가 아니라 시의 화자를 해치는 정적임을 알 수 있다. This paper was written to explain the social structure of the noble class in Zhou dynasty by revealing that the expression related to ‘朋友’ in the poems originally meant relatives of the same clan. From the Western Zhou to the early Spring and Autumn Period, bronze inscriptions and traditional texts such as Zuo Tradition show the usage of ‘pengyou’ as the meaning of a family relative of a nobleman. ‘Pengyou’ included brothers and relatives according to the context of the text. In Shijing, ‘pengyou’ was used in poems about ancestral rites, weddings, military and political conflicts. In Zhou period, ancestral rites were a ceremony for descendants of the same ancestor to gather to pray for blessings, so the clan rules were applied between the king and his subjects. Therefore, it is more accurate to see ‘pengyou’ as a clan of the royal family rather than a servant of the court. After the ritual, a banquet was usually held, and it was a place where the members of the family united through bonding. One of the main functions of the Zhou feudal system was to block military threats to the royal family by enclosing relatives as princes in various states. ‘Pengyou’ was a relative of the same clan, but politically, he was also a fellow subject of the same king. In Shijing, there are often stories of a relative who should have a strong friendship, but trying to shift the responsibility and even trying to harm the speaker of the poem by slander. It can be seen that ‘pengyou’ is not a colleague who shares the same pursuit, but an enemy that harms the speaker of the poem.

典故사용의 은유와 환유

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.

관상동맥내 경화반 타입 기반의 이상화된 이차원 경화반 모델에 대한 수치 해석적 연구

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.
