The major cause of periodontal disease is microorganism in the dental plaque. Gingival sulcular fluid, which is exudate released from the tissue near crevicular epithelium is related with inflammation. The purpose of this study was to evaluate the argon laser efficiency between the clinical index and onset of collagenase of gingival sulcular fluid. Material divided 16 patients into 4 groups. The first control was without treatmemt. The second was with just treatment of argon laser, The third was treated by scaling and root planning and the fourth was treated with both scailing and root planning and argon laser. The level of periocheck test, the index of bleeding, and the depth of periodontal pocket were evaluated from for 128 teeth of 64 anterior teeth and 64 posterior teeth. The results were as follows ; 1. In the score of periocheck test, root planing group(group 3) was significantly reduced more than the group without treatment(group 1) and the argon laser treatment(group 2) for results of 3 days and 7 days. But root planing plus argon laser treatment(group 4) in the 7days after experiment, was significantly reduced than no treatment(group 1) and root planing treatment(group 3)(P<0.05), in the 3 days after experiment, was significantly reduced than root planing(group3)(P<0.05). The score of periocheck test to the root planning group(group 3) were significantly reduced between days1, day3 and day7(P<0.05). Root planning plus argon laser group(group 4) were significantly reduced to 1 or 7days and 3 or 7days(P<0.05). The argon laser group(group 2) didn't show any changes. 2. In the case of sulcus bleeding index, the root planning group(group 3) and root planning plus argon laser group(group 4) were reduced more than without treatment group(group 1)(P<0.05) and sulcus bleeding index in the root planning group(group 3) were reduced more than the argon laser group(group 2)(P<0.05). 3. There wasn't any changes of pocket depth between the control and the experiment group as with experiment periods also.

In previous studies, Most scholars agreed that most effective strategy of Words of Mouth(WOM) is Seeding Programs. But, There were no studies on the type of WOMas a means of seeding program, type of social relationship and products as effective means. In this study, WOM as a means to spread the seeding program was divided by oral and written. When in-group and out-group to distinguish between social relationships, hedonic and utilitarian to distinguish between product, consumer preferences were studied. As a result of study, Oral WOM is effective including sign language, compared to only characters that written WOM. And in-group effect was higher than out-group. The greatest effect was observed when in-group, hedonic product, for oral WOM. But, The effect has been diluted by out-group, utilitarian product, writtenWOM. 기존연구에서 구전 마케팅의 가장 효과적인 전략은 파종 프로그램(seeding programs)이라는데 대부분 학자들이 동의하고 있다. 그럼에도 불구하고 파종프로그램의 수단인 구전의 유형과 대상, 제품 유형에 대한 구체적인 연구는 매우 미흡하였다. 본 연구에서는 파종 프로그램을 전파하는 수단인 구전을 말과 문자로 구분하고 구전의 대상을 내집단과 외집단으로 분리하였다. 또한 제품의 유형은 실용재와 쾌락재로 구분하여 구전의 효과가 어떻게 다른가를 살펴보았다. 연구결과, 메시지 자체만을 전달하는 문자 구전에 비해 몸짓 언어를 포함하고 정서전달이 용이하며 면대면의 속성을 가진 말에 의한 구전의 효과가 높았으며 외집단 보다는 내집단일 때 효과가 높았다. 한편 내집단 구성원 대상으로 쾌락재를 말에 의한 구전으로 전달할 경우 가장 큰 긍정적 효과가 나타났으나 외집단, 실용재, 문자에 의한 속성 반영시 긍정적 효과가 희석되었다.

“An imbalance between the rich and the poor is the oldest and the most fatal ailment of all publics.” This is a saying of the old historian, Plutarch. Inequality has become and will be one of key issues more and more over times in Korea. The reason may be that health is one of the most significant elements for mankind to survive. The reason may be that inequality in health is the worst inequality of all. Actually, there is no more serious inequality than the fact that you’ll die sooner only because you’re poor.<br/> The causes of health inequalities are very diverse. Originally, these stemmed from structural contradictions in a society such as class inequalities. Factors such as income, wealth, gender and post-code have an impact on people’s ability to fight illness.<br/> This essay is an attempt to describe inequalities in health such as mortality and morbidity by socioeconomic status in Korea. Socioeconomic inequalities were studied in relation to education level, household income and employment status, smoking prevalence, and geography etc. Consequently, the purpose of this study was to examine the current inequality in health and explore the patterns and trends of present health inequalities in Korea. In particular, I will emphasize the fact that to reduce health inequalities economic inequalities such as poverty should be dealt with fundamentally by focusing on social class contexts. Poor health is a determinant of social exclusion along all its dimensions (Burchardt, 2002). In conclusion, I will comment the government’s health polices for reducing health inequalities and suggest some implications.<br/> In this easy, I revealed the fact that inequalities in health have been wider in the past century and still widening in Korea. For this, I showed historical and practical evidences about health inequalities with the emphasis of economic inequalities such as poverty. These trends of widening have followed and are following socioeconomic polarization in Korea. In fact, tackling health inequalities is very tricky issue to solve because this issue fundamentally stemmed from economic inequalities based on social class and lots of other factors such as unemployment. Moreover, today, income and wealth inequalities are widening.<br/> Actually and originally, some claim that inequalities are inevitable. Are these out of hands? My answer is definitely no. we can deal with this issue. Just we need more wisdom, more consensus, more accurate policies and our will for narrowing health inequalities. For this, the most important thing is that inequalities in health can only be effectively tackled by policies that reduce poverty and income inequality (Shaw, 2003). Public health goals and health promotion programmes should be developed to reduce socioeconomic gaps in health status and improve the health among those with low levels of income and education (Kim, 2003). Korean government should give priority to reducing health inequalities in the social policy agenda. Actually, all human beings have their social rights for adequate living standards, protection against income insecurity and proper health services as well.

We obtained successful functional and esthetic results by grafting of iliac marrow- cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony supprt to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantrtal fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with preortodontic treatment. The other case, Bone grafting was done after removal of prosthesis with no preorthodontic treatment. 2. After mucopreiosteal incision in cleft area. The mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiograph and prostheic treatments of missing teeth were done.

Objectives : The authors performed this survey to find out current status of petition and process for the extension of hospitalization of patients who were hospitalized more than 6 months. Methods : Authors designed a questionnaire named 'Questionnaire for Survey of Current Status and Process of Petition for Extension of Hospitalization of Psychiatric Patients' and distributed it to 242 psychiatric facilities with closed wards for psychiatric patients. The psychiatric facilities includes 4 categories ; psychiatric department of university hospital, Psychiatric department of general hospital, psychiatric hospital and small sized private clinic. The period of survey was from Jan. 1 to Dec. 31 of 2002 Results : Among 84 psychiatric facilities responded, 2,615 petitions for extension of hospitalization were submifted to the Local Mental Health Tribunal, and the dissent rate was 4.1%. The most of petitions were from psychiatric hospitals (2,265). The psychiatric departments of general hospitals favored the discharge-readmission method rather than applying extension by due process of the Mental Health Act when further admission was needed after 6 months hospitalization (280 vs. 106). The main reason for the petitions for extension of hospitalization was "no improvement" (72.7%) than "dangerousness to self or others" (14.7%). Against doctor's recommendation for discharge agter improvement, many patients couldn't be discharged becanse of guardians' refusal or cut off from caregiver or guardian, In eluded were these patients applied petitions for exten-sion of hospitalization.Conclusion : This study suggests that hospitalization of some patients are extended improperly in view of the spihf of theMental Health Act. The authors proposea new system of ambulatory treatment, reinforcement of psychiatric rehabilitation,legal control of the neglected patient by guardians.
