When the men die, uniform changes progress. Many investigators have studied about the time after death, but it's very difficult to measure the time elapsed since death, particularly in highly decomposed or probably skeletonized bodies. But the teeth are very stable to the changes of physical and chemical properties and their changes are very slow. At this point of view, the author studied this theme as one of the pioneers in our country. In this study, the author observed the degree of the dentinal expansion and the crack of enamel and cementum of the teeth which had been extracted from December, 1983 to September, 1987. The teeth were extracted from the male and female who was 18 to 85 year old. The results are followed; 1. The degree of dentinal expansion increased rapidly until 7 months with high degree and then decreased slowly. 2. The equation of regression for representing x as the degree of the dentinal expansion and y as the time elapsed since death, is y = 29.43-1.13x (p<0.05) 3. The crack of the enamel surface seemed to begin at 1 year from extraction and to increase apparently before or after 20 months. 4. The crack of the cementum began at 3 months from extraction and dendrite crack began at 16 months from extraction. After this, the crack increase continuously and the rate of cracking were more rapid as compared with that of enamel. 5. It seems to be useful to measure the time elapsed since death using the degree of dentinal expansion and the crack of enamel and cementum, particularly in the old bodies after death.

The number of deaths is often measured to monitor the population health status and priority of health problems. However, number of years of life lost (YLL) is a more appropriate indicator in some cases. We have calculated the YLL of adult cancers and its trend over the past few years in Yazd to provide planners with baseline data. Data obtained from death registration system were used to calculate the YLL, based on each individual's age at death, and the standardized expected YLL method was applied with a discount rate of 0.03, an age weight of 0.04, and a correction factor of 0.165. All data were analyzed and prepared in Epi6 and Excel 2007. A total of 3,850 death records were analyzed. Some 550 patients in Yazd province aged ${\geq}20$ die annually due to cancer (male: female ratio 1.3). The average ages at death in lung, CNS, breast cancer and leukemia cases were 68.5, 59, 58.7 and 61, respectively. The age group of 40-59 with 21 % had the highest cancer mortality percentage. Premature cancer deaths have caused 40,753 YLL (5,823 YLL annually). Females lose on average more life years to cancer than do men (11.6 vs 9.8 years). Lung cancer (12.1%), CNS tumors (11.7%) and leukemia (11.4 %) were the leading causes terms of YLL due to all cancers in both sexes. From 2004 to 2010, cancer-caused YLL as a fraction of all YLL increased from 12.8 to 15.2 %. This study can help in the assessment of health care needs and prioritization. Cancer is the major cause of deaths and the trend is increasing. The use of YLLs is a better index for measurement of premature mortality for ranking of diseases than is death counts. Longer periods of observation will make these trends more robust and will help to evaluate and develop, better public health interventions.

There is a small portion of interstitial pneumonia which presents acute respiratory failure developing within several days. The course of illness is short and most patients die within weeks or months. This type of interstitial pneumonia has been variously termed Hamman-Rich syndrome, accelerated interstitial pneumonia, or the organizing stage of diffuse alveolar damage. We experienced a case of acute interstitial pneumonia in 42-year old female who showed clinical, radiological and histologic features of acute interstitial pneumonia without any identified etiologic agent.

A six-year-old, intact female Indian ring-necked parakeet (Psittacula krameri manillensis) was presented due to chronic weight loss and anorexia. The bird was tentatively diagnosed as proventricular dilation disease (PDD) by radiographic evidences of dilated crop and proventriculus. The patient was symptomatically treated, however the bird was die two months after the first presentation. At necropsy finding, distinctive signs of PDD were noted, and PDD concurrent with ingluvitis was finally diagnosed according to histopatholgic examination.

Objective: Alzheimer's disease is characterized by progressive, irreversible brain damage and cognitive decline. Although the diagnosis and treatment of the prodromal symptoms of dementia are important, no treatment for mild cognitive impairment has been currently established. Herein, we report the case of an 80-year-old female patient with memory complaints treated with Gugijihwang-tang, a traditional Korean medicine herbal formula, as an add-on medication. Case Presentation: The patient was diagnosed with mild cognitive impairment based on clinical examinations using the Mini-Mental State Examination (MMSE), the Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Activities of Daily Living (ADL) Scale, Global Deterioration (GDR) Scale, and Clinical Dementia Rating (CDR) Scale. She was treated with Gugijihwang-tang bis in die for 12 months while continuing her original medications, including 5-mg donepezil and 590-mg acetyl-l-carnitine. The MMSE score in the Korean Version of the CERAD Assessment Packet increased from 21 to 27 during the 12-month treatment period, and the CERAD 2 score increased from 33 to 62. The instrumental ADL scale score improved from 11 to 5. Other clinical examination results also showed improvement. The patient was satisfied and experienced no significant adverse events related to the Gugijihwang-tang treatment. Conclusion: This case suggests that Gugijihwang-tang could be considered as a treatment method for patients with mild cognitive impairment.

In South Korea, most patients who visit trauma centers with abdominal injuries have blunt trauma, and penetrating injuries are relatively rare. In extremely rare cases, some patients are admitted with a long object penetrating their abdomen, and these injuries are referred to as abdominal impalement injuries. Most cases of impalement injuries lead to fatal bleeding, and patients often die at the scene of the accident. However, patients who survive until reaching the hospital can have a good prognosis with optimal treatment. A 68-year-old female patient was admitted to the trauma center with a 4-cm-thick tree branch impaling her abdomen. The patient was transported by a medical helicopter and had stable vital signs at admission. The branch sticking out of the abdomen was quite long; thus, we carefully cut the branch with an electric saw to perform computed tomography (CT). CT revealed no signs of major blood vessel injury, but intestinal perforation was observed. During laparotomy, the tree branch was removed after confirming that there were no vascular injuries, and enterostomy was performed because of extensive intestinal injury. After treating other injuries, the patient was discharged without any complications except colostomy. Abdominal impalement injuries are treated using various approaches depending on the injury mechanism and injured region. However, the most important consideration is that the impaled object should not be removed during transportation and resuscitation. Instead, it should only be removed after checking for injuries to blood vessels during laparotomy in an environment where injury control is possible.

The spawning and growth of eightspine stickleback,Pungitius sinensis kaiborae (Tanaka, 19151, were investigated in the Chavang Stream from March 1990 to february 1991 as a part of study on its life history. Nest building, spavming and parental behaviors were similar to those known on the sticklebacks of Europe, North America and Japan. Bht f sinensis kaibarae in the Chayang Stream, peculiarly, showed only superficial gluing behavior in nest building phase and made two nurseries iust behind the nest in Parental Phase. The individuals with fully mature eggs were found from late February to late June. The fecundity of an adult female was about 21 to 110 (mean 47.07) eggs and the diameter of kllv matured ovarian eggs ranged 1.3 to 1.5 mm. The smallest female with fully mature eggs was 25.8 mm in body length and had 21 eggs. The relationship between the number of mature eggs in ovary and body length was No. of eggs = 2.857BL -55.134 (r = 0.890). The number of deposited eggs in a nest was 27 to 637 and thew were composed of several clusters of various developmental stages. The distribution pattern of gonadsomatic index (GSl) against the body length shown that in females 1+ year-old fishes mainly participate in spawning but in males 11 and 2+ year-old fishes equally participate. From the fluctuat지n pattern of GSI and the number of mature eggs in ovary, it was assumed that the spawning season was from February to June and the peak of spawning was early March to late April. The newly hatched vouns was found at late April and their body length was about 10 mm. The vouns (O+) grew rapidly until late August. Then their srowth was slowed down and finallY ceased in midautumn. The young reached about 35 mm BL in their first year of life. The halting of growth was lasted to next Sune when the spawning season would be nearly closed. They (1+) began to grow asain from late june, grew rapidly until tate september and reached about 415 mm BL. Then there was no more grouvth until to die as 2+ yearold fish. Therefore it was assumed that the life span of P. sinensis kaibarae in the Chavang Stream would be about ko years. The relationship between the body length and the body weight was logBW = 2.9541ogBL -4.802 (r = 0.998).

This study was practiced to provide basic data which is necessary for ethical education of dental hygiene students by comparing the bioethical perception between dental hygiene students and non-health students. Questionnaire surveys were conducted for 778 students in two universities in Gyeonggi-Do province and analyzed the collected data with SAS 9.2. The findings of the study were as follows : 1. there was no stastistical difference in the degree of bioethical perception between dental hygiene students and non-health students. 2. Students who have family member in medical field were more conscious of bioethics than students who doesn't. According to religion, the protestants were most conscious and no-religions scored the lowest. 3. In case of dental hygiene students, female was more conscious. According to religion, there were statistical differences between the Catholic and Buddhism, the Catholic and No-religion. 4. Dental hygiene students were more strongly opposed to let infant with fatal congenital disease die than non-health students. 5. Dental hygiene students were more strongly opposed to rejecting organ transplant, trade in human organs and using alternative organ of animal. Also, they estimated higher the possibility of medical irrationalities due to trade in human organs. From these results, a curriculum for bioethical education in department of dental hygiene should be developed to form and improve the more desirable bioethical perception of dental hygiene students.

Purpose : The purpose of this study was to identify hospice volunteers' perception of the death. Methods : This study was conducted with 327 adults who registered for the hospice volunteer education program in Severance Hospice Center from 1996 through 1999. The 4-years data was collected through a self-reporting questionnaire constructed and revised by the authors. The questionnaire was classified into 5 categories. The data collected were analyzed using SPSS/W. Results : 1) Hospice volunteers were mostly female(93.9%) with an average age of 48 years. The majority(82.6%) of the participants were Protestant. 2) From the 4-years data over 90 percent of participants thought of death as a process of life and responded positively to these three items : 'Death is a temporary separation from family', 'I will die in peace', 'Faith in God results in a freedom from fear of death'. 3) Age were statistically relevant to the following items: 'I often read the obituaries in the newspaper', 'Dying is a tragedy', and 6 items were significantly related to religion: 'I rarely think of dying unexpectedly', 'Death is a temporary separation from family'. 'Dying is a tragedy', 'We have to do our best to prolong life by use of modem medical technology', 'I feel comfortable thinking of death and dying, 'Faith in God results in a freedom from fear of death'. The finding that religiosity was related to perception of death is consistent with other reports. And $40{\sim}50$ year old Protestant women had more positive perception of death than $20{\sim}30$ year old women. Conclusion : The findings indicated an importance of considering the age and religiosity when we educate the hospice volunteers. And that will be a important basic-data to develope program for hospice volunteers.

An experiment was conducted to investigate types of injury inflicted by the stone leek leafminer, Liriomyza chinensis Kato (Diptera: Agromyzidae) on welsh onion. A feeding scar made by an adult female was a hole round in shape, with diameter of 0.08 mm and 0.48 mm in lesion, resulting in a white spot, many of which often form vertical dotted lines on a leaf. Egg spots were oval with 0.1 ${\times}$0.14 mm in size, one or several of which often form a V-shape in group. Feeding by adults began immediately after emergence and was very active from 4th to 5th day. Oviposition was done from 2nd to 6th day after emergence. In both feeding and oviposition, they were more active in the day time. Larvae after emergence crawled up the leaf at first, and then moved up and down to feed on mesophyll. When in high density, they feed on leaf from leaf tip to bottom, and let the leaf die. Area of damage per one larva was calculated as 72.1 $\textrm{mm}^2$. The aged larvae escaped from the leaf in early morning, usually between 5 and 7 am. Most pupation sites were distributed near plants,5cm in soil depth and within 10 cm away from the plant. Pupae of L. chinensis overwintered 10cm below soil surface and emerged from early May to late June the next year Adults then moved to welsh onions near over wintering sites, nursery, transplanted, and levee.
