The purpose of this study was to use fiber-optic nasolaryngoscope to find out differences in laryngeal behavior between persons who stutter(PS) and those who do not stutter(NS) upon their utterance. To meet the goal above, this study took 5 NS and 5 PS respectively as a part of sampling, so that they were all asked to join an experiment hereof. As a result, this study came to the following findings: First, there was not any significant difference in laryngeal behavior of uttering spoken languages between stuttering group and control. Second, there were some differences in laryngeal behavior of repetition and prolongation, which were a sort of disfluency revealed in the utterance of nonfluent spoken languages between stuttering group and control. Third, as reported by prior studies, it was found that there were differences in laryngeal abehavior of stutterer group's nonfluent spoken languages depending upon stuttering types. In this study, a variety of laryngeal behavior unreported in prior studies could be found. In addition, it was notable that stutterers showed different laryngeal behavior depending on their personal stuttering types. On block condition, Subject 1 showed laryngeal behavior of fAB, INT and fAD; Subject 2 showed laryngeal behavior of fAB, fAD and rAD; Subject 3 showed laryngeal behavior of fAD and rAD; Subject 4 showed only laryngeal behavior of fAD; and Subejct 5 showed laryngeal behavior of fAB, fAD and rAD. Summing up, these findings imply that when stutterers utter nonfluent words, they may reveal a variety of laryngeal behavior depending on their personal stuttering types. Moreover, it is found that there are more or less differences in the utterance of nonfluent spoken languages between NS and stuttering ones. In particular, it is interesting that one common trait of nonfluent spoken languages uttered by PS is evidently excessive laryngeal stress, no matter which type of stuttering they reveal.

Some structural members of large-scale marine vessels such as large-scale offshore structures and very large container ships are assembled by very thick plates of which thickness exceeds 60mm. Also, high-tensile steels have been selected to meet the required structural strength and fatigue strength. Generally, multi-pass welding method such as FCA(Flux-Core Arc) welding has been used to join the thick plates. Considering the welding residual stresses, fatigue strength of the welded joints of thick plates should be assured since the residual stress influences the fatigue strength. This paper presents a numerical procedure to investigate the residual stress of structure joined by multi-pass FCA welding so that it can be incorporated into the fatigue strength assessment considering the effect of welding residual stress. The residual stress distribution is also measured by X-Ray diffraction method. The residual stress obtained by the computational model also has been compared with that of experiment. The results of FEA are in very good agreement with the experimental measurements.

This study analyzed the awareness and demand of participants in a physical activity therapy program(PATP) of a social welfare-type cultural regeneration space in urban and rural areas. As a result of analyzing the demographic characteristics, the female(68.4%) were more than the male, and 30-39 years old(53.3%) were the most generation in the PATP participants. As a result of frequency analysis by all subjects, gender and age, 78.4% of the respondents had never participated in PATP before. The most duration of the PATP was 30 to 60 minutes(24.6%). 73.5% of the respondents answered that it was not feeling difficult at all to the intensity of PATP, and 94.8% of the respondents were satisfied with the intensity of PATP. The most respondents preferred to participate again with if the new PATP starts(97.2%) and to join the new PATP with his or her family members(85.7%). In addition, the participants under the age of 39(24.3%) perceived that the effect of improving physical fitness by PATP was higher than over 40 years of age(11.9%). As a result of logistic regression analysis, it was found that only the age had a significant effect(p<.01) on intensity of PATP. It means that the perceived intensity of PATP was different between the older and young generation. However, the PATP was not designed to meet the participants age and fitness levels, and even the general exercise prescription guidelines based on professional scientific data such as exercise frequency, exercise intensity, exercise time, exercise type, and characteristics of the participants in the spaces. In conclusion, to encourage and promote the participants motivation and health-related fitness level in the spaces for the future. The various type of PATP that include a few different intensities for all genders and age groups, and a customized program based on systematic and scientific exercise prescription guidelines.

The purpose of this study was to examine the state of visiting oral health programs and the opinions of dental hygienists on the programs in a bid to help boost the efficiency of visiting oral health programs, To meet the goals, 341 dental hygienists in public dental clinics across the nation were asked to join a questionaire survey via e-mail in September 2007, After their views were investigated, the following findings were given: 1. In regard to the management of visiting oral health programs, 44,3 percent of the respondents carried out visiting oral health programs, and 48,3 percent of that group did that in association with visiting health care programs, There were differences among the public dental clinics in beneficiaries of visiting oral health programs, beneficiary selection criteria and the details of oral health programs, which indicated the necessity of the development of standardized models. 2. As to difficulties in fulfilling visiting health care programs, a shortage of professional knowledge was viewed as the greatest hurdle, All their scores were above average, which implied that they were not able to perform the programs successfully. 3. As for the necessity and additional expected effects of visiting oral health programs, the largest number of the dental hygienists who carried them out expected that the programs would serve to change the mind-set of locals about themselves, And the others who didn't placed the most emphasis on cooperation from other departments, and the two groups had a statistically significantly different opinion. 4. Concerning the details of visiting health care programs, the dental hygienists who performed the programs found it most necessary to provide oral health education to employees and families to be visited, The others who didn't considered it most necessary to offer oral health education to people to be visited, The necessity of denture and prosthesis was least stressed by both groups, and they took a significantly different view of treatment for dental diseases, denture and prosthesis. 5. Regarding how to bolster visiting health care programs, the dental hygienist group that carried them out put more emphasis on everything suggested in the survey, Specifically, they attached greater importance to securing sufficient budget, establishing legal foundation, setting up an administration system and determining the directions for the programs in a realistic manner, which signified the desperate need for administrative and institutional backing.

The purpose of this study is to analyze the consumer's expectation before the health care service and the consumer's satisfaction after it. The participants of the study are inpatients in a general hospital located in Seoul. The resources were collected from the self-administration questionnaire survey run parallel with face to face interview. In order to measure the degree of the consumer's expectation, 349 samples were collected from the first questionnaire survey on the date of admission to the hospital. The second questionnaire survey was carried out on the date of discharge to the hospital with the participants responding to the first questionnaire survey. There are 154 samples collected from this survey. The results from the analysis of these resources are as follow. First, the survey shows that one of the highest consumers' expectations was about the generosity, kindliness and sincerity from the staff at the hospital, specially from doctors. Second, according to the analysis of the factors affecting the expectations of the consumers, with regard to path of admission to a hospital relating to patient's features, outpatient who gets into a hospital expected good medical care much more than the other patients. In regard of doctor's features, patients usually and highly expect good medical care from doctors who have good carrier and much experience. Third, according to the second questionnaire survey, what patients are satisfied most with is about the generosity and sincerity from staff at a hospital, especially from doctors and their gem attitudes. The results from survey show that the differences among the degree of consumers' satisfaction are very variable, depending on surrounding environments and facilities. The only fact that expectation didn't meet with satisfaction appeared to the case about technology and skill of medical care and the case about updated medical skills and equipments. Fourth, comparing the degree of expectation with the degree of satisfaction of consumers, correlative analysis was concerned significantly and specifically about the part of overall cleanliness relating to facilities and surrounding environments, the items about medical examination and test plan procedure relating to skill of medical care, professional specialties and convenience for procedure, and the items about satisfying explanations and concern about patients from doctors relating to staff's generosity and sincerity. Fifth, the analysis of the factors affecting the degree of how much patients are satisfied with shows that relating to sociodemographical features, patients are not satisfied with the case when the time and process of medical treatment are getting longer. It is surveyed that consumer were satisfied with the motivation to visit a hospital and the insurance type in patient's feature and so were the medical department and the factor of the degree of the expectation in disease's feature. Sixth, according to analysis based on the survey, patients would join again a hospital when they get satisfaction from the medical care and also they want to come again regarding to doctor's capability. For example, when doctors are old, have a good carrier and much experience, patients would come again. As seen from the above, consumers are usually satisfied with the medical treatment more than that they expected before. They would intend to use again when they get satisfaction from the medical care provided at a hospital. Patients and consumers highly expect good attitude as well as capacity from medical doctors and they are also generally satisfied with those things. Therefore, in order to increase the degree of consumer's satisfaction and their intention to come again, the hospital staff would have to commit themselves to achieve high quality service continuously and would have to make an effort to offer the finest quality service.

한국 유통산업이 무한 경쟁에 박차를 가하고 있다. 저성장시대를 맞으면서 각 소매업태간의 경쟁 중에 힘이 약한 자는 생존의 문제에 직결되기 마련이다. 근 수년간 대형할인마트가 매년 꾸준한 성장세를 보여 왔다. 그러나 점포수의 포화, 신규부지 확보의 어려움, 불경기로 인한 소비자의 소비행태 변화 등의 이유로 고객밀착형의 새로운 업태의 진출을 모색하게 되었다. 이에 따라 최근 대기업은 대기업 계열 기업형 슈퍼마켓을 만들었고 전통시장 상권에 따라서 대형유통업체의 막강한 바잉파워를 배경으로 SSM이라는 신업태에 역량을 집중하여 전국적 다점포화를 공격적으로 전개해 왔다. 이러한 출점은 지역사회에 기반을 둔 중소유통 그중에서도 일정규모이상의 개인 슈퍼마켓에 직격탄을 날리고 있다. 개인 슈퍼마켓과 소매상인들은 낡은 판매시설과 기존 운영방식으로 인하여 사업의 경쟁력을 잃어가고 있다. 최근 대기업 계열 기업형 슈퍼마켓의 전통시장 상권에 대하여 언론, 학계, 업계 등에서 매우 논란이 많고 이와 관련된 세미나와 공청회도 많이 열리고 있다. 이에 따른 규제로 출점 속도를 늦출 수는 있으나 결정적 대안은 아닐 것이다. 기업형 SSM이 최근 급증하는 이유는 정체로 접어든 오프라인 할인마트 업체들의 새로운 성장분야를 찾기 위한 목적이 크다. 이미 대형할인마트 형태로는 전국 대부분의 지리적 요지에 다 입점해 있어 포화상태에 이르렀기 때문이다. 할인마트로 커버하지 못하는 소규모 상권을 공략하기 위해서는 SSM 형태의 사업이 확대가 절실하다. 이에 반하여 개인 슈퍼마켓은 경쟁력을 잃어 간다. 개인 슈퍼마켓의 취약점은 가격적인 면에서 규모의 경제를 실현 할 수 없기에 소량으로 판매 물건을 구입하고 있으며, 이로 인해 구입단가 할인이 어려운 상황이다. 또한 조직화 및 협업화가 부진하고 상인교육이 활성화 되지 못한 부분이 서비스로 직결되기 때문에 힘든 상황이다. 이에 따른 해결책으로 농산물, 청과, 공산품 등의 전문점을 만들어 상권을 형성하는 방법이 있다. 둘째, 개인 슈퍼마켓의 가맹점 가입 추진을 통한 조직화. 협업화를 촉진하여 규모의 경제를 취득함과 동시에 정부에 제안 할 수 있는 하나의 기업형태가 되는 것이다. 셋째, 중소상인 교육의 활성화로 서비스 의식을 고취하고 좋은 서비스로 소비자를 모아야 한다는 점이다. 또한 SSM에서 할 수 없는 심리적 점포 운영으로 소비자의 심리를 자극 하는 것도 하나의 방법이 될 것이다. 일본에는 이미 전일식 체인으로 소상공인들의 생활이 한편 나아졌다. 이에 개인슈퍼마켓을 비롯한 중소유통점들의 취약 부분을 알아보고 경쟁력 강화 방안에 대해 자세히 제안하고자 한다.
