  • In this paper, a two-stage group sampling plan based on the time truncated life test is proposed for the Weibull distribution. The design parameters such as the number of groups and the acceptance number in each stage are determined by satisfying the producer's and consumer's risks simultaneously when the group size and the test duration are specified. The acceptable reliability level is expressed by the ratio of the true mean life to the specified life. It was demonstrated from the comparison with single-stage group sampling plans that the proposed plan can reduce the average sample number or improve the operating characteristics.

  • Carbon coils could be synthesized using $C_2H_2/H_2$ as source gases and $SF_6$ as an incorporated additive gas under thermal chemical vapor deposition system. The substrate with oxygen incorporation and the substrate without oxygen incorporation were employed to elucidate the effect of substrate on the formation of carbon coils. The characteristics (formation densities, morphologies, and geometries) of the deposited carbon coils on the substrate were investigated. In case of Si substrate, the microsized carbon coils were dominant on the substrate surface. While, in case of oxygen incorporated substrate, the nanosized carbon coils were prevail on the substrate surface. The cause for the different geometry formation of carbon coils according to the different substrates was discussed in association with the different thermal expansion coefficient values between the substrate with oxygen incorporation and the substrate without oxygen incorporation.

  • The purposes of this study are to experiment a modified domestic conflict containment program (DCCP) which was initially development for developed by Dr, Neidig on 10 Korean offenders, and to provide practical basement for development of Korean offenders' group. This modified group program is based on cognitive-behavioral and communication theories. The group was leaded by 2 therapists, one female and one male, and continued 12 consecutive weeks, each week for 2 1/2 hours. The evaluation on the program is based on 4 different data: 1) intake form for spouse abuse, 2) group leader's summary on each session based on video taping and an analysis after each session with two probation officers in charge for the offenders, 3) clinical measurement for self esteem (ISE), 4) daily self report on each session and the final evaluation form by the group members. The result was shown consisently that this program achieved the purpose of this study across the all 4 data. Therefore, we suggest our experimental study will be able to provide a practical basement for future development of group treatment model for Korean offenders.

  • This study was performed to determine the inter-rater reliability of the Chedoke-McMaster Stroke Assessment translated in Korean. This measures the physical impairments and disabilities that impact on the lives of individuals with stroke. The purposes of this measure were 1) to stage motor recovery to classify individuals in terms of clinical characteristics, 2) to predict rehabilitation outcomes, and 3) to measure clinically important change in physical function. Twenty-two subjects from physical therapy unit were assessed by two physical therapists. The ratings were compared by Spearman's rank correlation The correlation between two raters ranged from 0.85 to 0.98. Inter-rater reliability coefficient for total scores ranged from 0.95 to 0.97. This study confirms that the Chedoke-McMaster Stroke Assessment yields reliable results.

  • The present paper extends the idea of tightened-normal-tightened sampling scheme to group acceptance sampling plans under the time truncated life tests. We consider three famous distributions that are widely used in the area of reliability such as the generalized exponential distribution, the Weibull distribution, and the Birnbaum-Saunders distribution in the proposed sampling plan. The plan parameters are determined such that the producer's risk and the consumer's risk are satisfied at the specified median life. Extensive tables showing plan parameters are provided at various values of the experiment time and the consumer's risk for each of three distributions for the practical use. Some examples are given to illustrate the procedure of the proposed plan.

  • Unlike the Democratic nomination, Republican nomination struggle has ended with an easy victory of Senator John McCain. This paper claims that the easy victory of McCain should not be interpreted as Republican's return to the median voter, because it masks religious schism and ideological discord among the Republicans. Christian rights were still reluctant to support McCain mostly due to his liberal position on social issues. In addition, the conservatives who request stricter immigration policy presented the mixed feeling toward the Republican candidate. Even though McCain chose the harmony inside the Republican party, rather than sticked to his liberal attitude toward social issues during the campaign for 2008 general election, McCain's defeat is unlikely to result in a rapid change in the Republican party.

  • The bicuspid aortic valve (BAV) is the most common congenital cardiovascular malformation. Patients with BAV are at higher risk of other congenital cardiovascular malformations and valvular dysfunction, including aortic stenosis/regurgitation and infective endocarditis. BAV may also be related to aortic wall abnormalities such as aortic dilatation, aneurysm, and dissection. The morphology of the BAV varies with the presence and position of the raphe and is associated with the type of valvular dysfunction and aortopathy. Therefore, accurate diagnosis and effective treatment at an early stage are essential to prevent complications in patients with BAV. This pictorial essay highlights the characteristics of BAV and its related congenital cardiovascular malformations, valvular dysfunction, aortopathy, and other rare cardiac complications using multimodal imaging.

포스트 코로나 시대의 소비문화에 대한 기독교교육의 성찰 : 드라마 「펜트하우스」를 중심으로 (A Reflection on the Consumer Culture in the Post-COVID 19 Era from the Lens of Christian Education: Learning from the Drama, Penthouse)

  • 이 연구는 기독교교육의 성찰을 위해 보드리야르(J. Baudrillard)의 중요개념인 시뮬라시옹(Simulation)과 시뮬라크르(Simulacra) 등을 중심으로 포스트 코로나 시대의 한 단면을 분석할 수 있는 드라마 「펜트하우스」의 소비이데올로기, 이미지의 욕망 및 폭력 등에 관해 검토할 것이다. 보드리야르는 시뮬라시옹 개념이 대중매체의 발전에서 생겨났다고 보고, 대중매체는 결국 실재를 사라지게 하는 '시뮬라시옹의 출현' 혹은 '시뮬라시옹의 과정'이라고 설명한다. 보드리야르는 시뮬라시옹 과정이 대중매체가 지배하는 소비사회의 다양한 영역에서 진행되고 있다는 것을 지적한다. 시뮬라시옹은 이미지에 의해 실재보다 더 실재적인 초과실재를 산출하는 과정이며, 시뮬라크르는 시뮬라시옹의 결과이다. 포스트 코로나 시대의 기독교교육은 비판이론을 통한 비판적 성찰의 준거 기준이 합의 되지 않았다는 부정적 측면으로 인해 거부하지 말고 비판이론의 긍정적 입장을 고려해야 한다. 다시 말해서 대중매체가 주도하는 지배이데올로기와 소비이데올로기의 속성을 봐야한다. 특히 광고나 드라마 영화에서 보여주는 메시지는 시뮬라크르만 남아 실제보다 더 실제 같은 허상임을 보는 관점을 지녀야 한다. 미디어는 말을 하되 상대방의 응답이 이루어질 수 없게 만드는 미디어의 권력을 의미한다. 그것의 대표적인 예표가 텔레비전이며, 연구자가 드라마 「펜트하우스」를 분석하는 이유이기도 하다. 보드리야르는 맥루한(M. McLuhan)의 "미디어가 메시지다"(The medium is the message)라는 명제는 예상치 못하게 모든 내용물과 메시지가 미디어 속으로 사라져 버린 뒤에, 미디어 자신도 증발해 버린다고 지적한다. 그러나 기독교교육은 "하나님 말씀이 메시지"(The word of God is message)임을 가르치고, 배우고, 나누고, 전수하는 것이다. 또한 그 메시지는 내파되거나 함열되는 것이 아니라 영원한 진리로 계속 살아있는 메시지이다. 위기와 불안의 포스트 코로나 시대의 기독교교육은 사회 현상과 관련하여 대중/소비자/교인 개체들을 무저항적이고 무비판적으로 만드는 소비지상주의의 소비문화에 관해 끊임없는 성찰의 장(場)을 마련하고, 일련의 '전망대'의 역할을 감당해야 할 것이다.

  • Extension of advanced odontogenic infection from deep neck fascial spaces into the mediastinum is heralded by chest pain, dyspnea, fever, and radiographic demonstration of mediastinal widening. The critical care should be done in a team approach by multiple medical and dental departments, such as, oral & maxillofacial surgery, otolaryngology, anesthesiology, chest surgery, and infection medicine. Especially, fluid & drug therapy, adequate incision & drainage and systemic supportive psychosedation care are important. But, acute hyperventilation can be produced by several distinct causes: severe anxiety, respiratory alkalosis, increased blood catecholamine levels, and a decrease in the level of the ionized calcium in the blood. The orofacial fears about acute pain, trismus, dysphagia, swelling and oral surgical treatment lead to the severe anxiety and increased blood catecholamine level by stress. Therefore, the most dental patient should be cared gently as the stress reduction protocol. In spite of the care, hyperventilation was occurred during psychosedation and local anesthesia for incision and drainage of the masticatory fascial space abscess with deep neck infection & mediastinitis. We suggest that the dental patient with advanced odontogenic infection must be attention for the manifestation of hyperventilation, especially in the medically compromised conditions.
