The purpose of this presentation is to review the situation of the Cheju broiler industry peculiarized with the integrated production and marketing system to some degree, which is not prevailed in the whole broiler industry in Korea, so as to study the case of the Cheju industry from the viewpoint of an economic integration. The economic integration in the broiler industry is grouped into three patterns： non-integration, quasi-integration and complete integration, which generally exist under the different type of market competition. The quasi-integration tends to be formed at all phases where the complete integration is not fully implemented, but the non-integration has begun to change its nature into partially integrated structure. The Cheju broiler industry is characterized by the geographical location of isolated market so that factor supplies and broiler products are marketed in the different conditions from those of mainland Korea, somewhat in an oligopolistic pattern. It was since early 1980's that the industry successfully had three dressing plants merged into one by virtue of entire growers ownership, which opened an era of an integrated industry centered on the function of dressing birds. The case of Cheju broiler industry today is to be referred to as a typical quasi-integration which is coordinated the function between growing and dressing birds directly and extended the functional cooperation to distribution of products indirectly, while factor supplies are traded independently. As a result of a quasi-integration, the growers are able to receive a fixed price set by the dressing plant of growers that has the power to adjust the supply of and demand for broilers produced and consumed in the Island. There are some problems, however, in the integration of the Cheju broiler industry, stemming mainly from the process of the structure change, ： 1) the difficulty of controlling the production of broilers, 2) continuing pressure on the integration by non-integrated sectors, 3) the challenge on the stabilized broiler market from the mainland, 4) limited effectiveness of consumer education activities, and 5) lack of leadership for the industry development through integration. It is projected that the partially integrated Cheju broiler industry will be continually developed toward the direction of a complete integration in due course, as the currently independent supply sectors are to be backward integrated. The case of the Cheju broiler integration, therefore, could be used as a reference for making the whole broiler industry in Korea develop toward the integrated structure in the future.

This study was carried out to evaluate diagnostic criteria of noise-induced hearing loss (NIHL) among-workers in an iron foundry. Of 1,093 workers under the observation of noise-specific health examination, 184 workers were selected by way of first and second screening audiometric examination. A questionnaire survey, otological examinations, Rinne test and audiometric test were performed and the results were as follows ; The degree of hearing impairment in the left ear was more severe than in the right ear (p<0.05). The difference between hearing threshold of the first and the second hearing test at 1,000 Hz was about 5 dB with a narrow range of deviations while the difference at 4,000 Hz was about -7 dB with a wide range. Of the total study workers, 84.8% were tested within 15 hours away from noise exposure, and the rest after 16 hours. This study has identified that mean hearing loss at 4,000 Hz showed a significant statistical difference among the two study groups while mean hearing loss by 4-divided classification did not. The same phenomena were observed between the group with and without tinnitus and between the group with and without difficulty in hearing (p<0.05). Among 184 workers, 10 workers (5.4%) diagnosed as NIHL by old diagnostic criteria in contrast to 150 workers diagnosed as NIHL by the new diagnostic criteria. There was a significant difference between the two groups in the average hearing loss at 4,000 Hz and 4-divided classification (p<0.01), but there were no significant differences in age, the duration of employment, blood pressure and the duration wearing the personal hearing protector (p>0.05). If we apply Early Loss Index (ELI) method, some workers in younger age group diagnosed as NIHL by the new diagnostic criteria were fallen into within the normal range. In the mean time older age group show reverse results in contrast to the above finding. It is too early to confirm the value of the usage of the new diagnostic criteria in hearing examination. Further study is called for to verify the value of this criteria.

As a descriptive survey, this study was attempted to get basic data necessary to recognize the factors that disturb the therapeutic atmosphere of hospital wards as perceived by nurses and hospitalized patients, to identify differences between the perceptions of the nurses and of patients. The subjects, 159 patients in Pusan National Hospital and 68 nurses working there were sampled between March 18 and April 13, 1996. The tool used to measure the disturbing factors was an amended form of the one developed by Kim, Mae Ja(1983). The differences between each subject's score for each factor were analyzed using means & SD. and the highest 3 items above the mean score for each factor were collected and compared. The results are described below : 1. Subject's perception of main disturbing factors : patients reported that the main factors were 'loss of role & economic trouble', 'the prognosis of disease', 'the change of daily life' but nurses replied that the main factors were' the prognosis of disease', 'the communication trouble with the medical team & interpersonal relationships'. 'The change of daily life' was not a perceved factor by nurses, but ranked third by the patients. 2. Subject's perception degree of each disturbing factor : (1) among the items related to interpersonal relationship. the patient group reported that the worst disturbance was dur to severely ill patients in the same room' but the nurse group regarded 'greed to monopolize wheelchairs or other supplies' as the worst disturbance. (2) among the items related to physical factors. the patient group regarded 'limitations to wash their body, physical pain and limitations in physical activity' as the worst disturbance, but the nurse group regarded' physical pain', and 'limitations to activity or change of appearance' as the worst disturbance. (3) among the items related to the change of daily activity, the patient group regarded 'the boredom of hospitalization or infavorable diet' as the worst disturbance, but the nurse group regarded 'too much noise or unclean room' as the worst disturbance. (4) among the items related to the communication trouble with medical team, the patient group regarded 'the ignorance of their disease due to poor information. the inability to understand the language of the medical team or the difficulty in seeing physician in time' as the worst disturbance, but the nurse group regarded 'the inability to trust physicians and physician's poor attention to patients' as the worst disturbance.

전통적으로 대학에서 개설되는 통계학 강좌의 지향점은 통계적 지식과 기술의 습득 여부에 주된 초점이 맞추어져 있었다. 그러나 최근 연구에서 통계에 대한 태도와 같은 비인지적 요인이 통계학 성취도에 유의미한 영향을 미치는 것으로 나타나 통계 학습에 대한 긍정적인 태도의 함양이 통계 지식 및 기술의 습득 못지않게 중요한 통계학 강좌의 과제로 부각되었다. 이에 해외에서는 통계에 대한 태도를 측정하는 검사의 개발 및 타당화 연구가 많이 이루어졌으나 국내는 아직 미비한 실정이다. 따라서 본 연구에서는 통계에 대한 태도를 가장 타당하게 측정하고 있다고 평가되고 있는 SATS-36(Survey of Attitudes Toward Statistics-36; Schau 등, 1995)을 우리나라 대학생들의 특성에 맞게 수정한 한국판 통계에 대한 태도 검사(K-SATS)를 타당화하고자 하였다. 예비분석 결과 원척도의 6요인이 아닌 흥미, 가치, 인지적 역량, 용이성, 노력의 5요인 구조가 한국 학부생 및 대학원생들에게 적합한 것으로 나타났으며, 본 검사 분석 결과 K-SATS의 신뢰도와 구인타당도가 확인되었다. 또한 K-SATS의 전체 혹은 하위 척도별 점수에서 성별, 강좌 수준, 학위 과정, 전공 계열에 따라 학생들의 통계에 대한 태도에 유의한 차이가 있는 것으로 나타났다. 이러한 연구 결과를 토대로 한국판 통계 태도 검사가 추후 연구와 교수방법에 주는 시사점에 대해 논의하였다.

Purpose: The purpose of this study is to suggest direction for dental technicians and management of dental laboratories to contribute to the improvement of oral health of citizens with high-quality dental prosthesis by researching operational status and management satisfaction of dental laboratories. Methods: In order to investigate operational status and management satisfaction of dental laboratories, this study conducted a questionnaire survey by mailing questionnaires to heads of dental laboratories designated as clinical training workshops of Department of Dental Technology of G University and a total of 158 questionnaires were used for analysis. Results: As for gender, males were 142 persons (89.9%) and females were 16 persons (10.1%). For location of the laboratories, number of laboratories in metropolitan cities was 94 (59.5%) while small and that in mid-sized cities was 64 (40.5%). As for the satisfaction with job, those who have managed dental laboratories for 23-30 years ($1.92{\pm}77$), transact with 7-12 dental clinics ($1.70{\pm}75$), had monthly income of 4-8 million won ($1.74{\pm}.80$) and had 8-10 employees ($2.33{\pm}.68$) were the highest in their satisfaction. As for satisfaction with management, those who have managed their business for 15-20 years ($2.86{\pm}.52$), transact with more than 20 dental clinics ($2.00{\pm}.04$), had monthly income of less than 4 million won ($2.00{\pm}.85$) and had less than 3 employees ($2.00{\pm}.62$) were the highest in their satisfaction. As for monthly income, those with less than 2 million won were 24 persons (15.2%), 2-4 million were 64 persons (40.5%), 4-6 million were 40 (25.3%), 6-8 million were 14 (8.9%) and over 8 million won were 16 persons (10.2%). As for number of employees, those with less than 3 employees were 32perosns (20.3%), 4-7 were 82 (51.9%), 8-10 were 26 (16.5%) and more than 11 were 10 persons (6.3%). As for severance payment, 84 persons practiced it according to Labor Standard Act (53.2%) and 34 practice it to a proper degree (21.5%) while 20 did not practice it at all (12.7%) and 20 persons did not respond to the question (12.7%). Conclusion: Although dental laboratories have rapidly expanded in number from 473 in 1986 to 2,400 in 2015, dental technician circles are facing difficulty in their management due to fierce competition and low profitability. Therefore, in order to improve this problem, it is necessary to readjust prices for dental prosthesis to realistic ones.

산사태가 일어날 지점을 예측한다든지 사태물질로 인한 피해 예상지역을 알아내는 것은 쉬운 일이 아니다. 이는 산사태를 발생시키는 요인들이 여러가지가 있고 개개의 요인들이 산사태를 발생시키는데 기여하는 중요도도 서로 다르기 때문이다. 그러나 많은 산사태자료에 대한 분석을 바탕으로 발생 메커니즘 규명과 통계적 해석기법을 통해 산사태 발생가능성의 예측과 위험지역의 분류가 가능해졌다. 석조문화재가 산사면 또는 그 직하부에 인접해 있는 경우는 산사태가 발생되면 재해에 무방비로 노출되어 있다. 이 연구에서는 여름철의 집중호우 등에 의해 석조문화재 및 그 주변지역에 산사태가 발생할 가능성을 사전에 예측함으로써 그로 인한 석조문화재의 피해가능성을 분석하고자 하였다. 이러한 목적을 위해 2002년 8월 산사태재해로 인해 피해가 발생된 바 있으며 중요 석조문화재가 위치해 있는 실상사 백장암지역을 연구대상지역으로 선정하여 산사태 예측도를 작성하였다. 그리고 산사태재해 가능성을 발생확률로 표현하여 등급별로 구분함으로써 석조문화재 및 그 주변지역이 산사태에 취약한지의 여부를 평가하였다. 또한, 이러한 조사 및 해석기법을 앞으로 석조문화재 주변의 산사태재해 예측 및 평가를 위해 실용적으로 활용할 수 있는 토대를 마련하였다.

Introduction: Stroke refers to a sudden brain disease that results in disorders in the anatomy of the brain. The cause is a sudden circulatory disorder of the cerebrovascular system that creates a consciousness disorder and hemiplegia. Despite aggressive treatment after the onset, stroke is a social problem because the patient has difficulty in recovering from sequelae that can include limb movement disorders, language disorders, and emotional disorders. In this study, we describe the effect of traditional Korean medicine treatment on the sequelae in a subacute cerebral infarction patient admitted to a Korean medical hospital. Case presentation: A 67-year-old male patient was diagnosed with cerebral infarction circa 2005, and his condition had not improved. Around March 15, 2018, he experienced the sudden onset of a cerebral infarction in his daily life. This was confirmed by a brain MRI, and he was hospitalized at other hospitals, but he showed no improvement. We conducted a manual muscle test (MMT) to evaluate the patient's exercise and strength. His gait level was measured to evaluate his degree of walking. He was treated with Bojungikgi-tang and acupuncture twice a day. After 34 days of inpatient treatment, the patient's exercise strength improved from Grade 2+~Grade 3 to Grade 3+ determined by the MMT, and his walking ability improved from Gait Level 3 to Gait Level 4. Conclusion: The findings of this study indicate that acupuncture and herbal medicine treatment can help treat patients with hemiplegia due to cerebral infarction.
