Idod (Immediate Dissolved Oxygen Demand) is a value of the oxygen demand after 15 minute of inoculation by inorganic reducing salts. Industrial development and urban enlargement are bringing water pollution deeply, and industrial waste waters are the source of the inorganic reducing salts. Author investigated the IDOD value change according to the inorganic salts and gained the following results: 1. IDOD value influenced by Na2SO3 is 81.4 ppm. 2. Generally sulfur compounds are highly effecting on IDOD. 3. The nitrite salt had little influence on IDOD.

To find a basic study for manpower of physicians and medical care systems in Busan, author has studied towards 1,069 doctors who had taken the regular report in 1973, residing in Busan City. The survey was conducted from July 1 to August 31, 1973 and the findings & results obtained through the study for distributions, characteristics, employment of doctors and some medical systems were summarized as follows; 1. The ratio between doctor and populations in Busan City was 1:1,887. 2. The doctors who graduated from Busan Medical College were 438 as the most proportion(40.9%). 3. Sex distribution of doctors revealed male 970, female 99 and those belonging to the 30-39 age group were as the most proportion(41.0%). 4. The doctors who had faith in Christianity were the highest (22.3%). 5. By the opening year of clinics, there was increasing tendency after 1950, especially during 1970-1973. 6. At that time of investigation, the doctors who had private clinics were 673(67.3%) and nonemployees were 27 (2.5%). 7. The total Medical Specialists in Busan were 519, and among them the Internal Medicine Specialists were the highest proportion (16.2%). 8. The clinics employing the disqualified nurse-aids were 237 (22.2%). 9. Most of doctors (81.8%) had opposed attitude to the establishment of new medical colleges. 10. More than half of the doctors (59.8%) agreed to the functional division between Physicians and Pharmacists. 11. The ratio of agreement to the practical application of public medical insurances was 68.7%. 12. The opinion by opening hospital-clinics at Myeon for administrative measures for doctorless rural area was the highest proportion. 13. The doctors who replied as low state of confidence of the citizens to the doctors-themselves were 691 (64.6%).

BACKGROUND: Snoring is a risk factor for cardiovascular disease. There has been little research done on the factors associated with snoring among adults by sex in Korea. The purpose of this study was to assess the prevalence of habitual snoring in the Korean population and to evaluate its related factors by sex. METHODS: The study subjects were 2,007 volunteers aged 40-69 years who participated in regular health check-ups (male: 434, female: 1,573) from May to December in 2012. Standard interviews, anthropometrics and biochemical studies were conducted. Habitual snoring was defined as snoring more than 4 days per week. RESULTS: The prevalence of snoring in our sampling pool was 52.9% (male 61.6%, female 47.1%) and habitual snoring was 13.7% (male 21.1%, female 11.5%). Multiple logistic regression analysis revealed that habitual snoring was independently associated with sex, age, hypertension and body mass index (P<0.05). Fatty liver was independently associated with habitual snoring in males whereas age, waist circumference and body mass index were independently associated with habitual snoring in females. CONCLUSIONS: Snoring and habitual snoring may be predisposing factors for cardiovascular disease. There are significant associations between habitual snoring and sex, age, alcohol use, hypertension and body mass index.

This research was undertaken to explore the degree of clinic utilization, medical cost, and disease patterns in a Korean rural area. The Kojedo Project was selected because it is one of many 'Front Line' medical facility, offering readily accessable primary care to the logical population, but with a particular emphasis on simple treatment and public health measures. During 1973, 14,808 patients visited the clinic from which 3,621 were selected as a sample for analyzation, the result was as follows; 1. Utilization, by geographical distribution, was highest in 'A Zone' the area closest to the clinic, with 46 percent of the population of that area making use of the facilities. 2. Utilization, by sex and age distribution, was higher for males less than one year old (50 males: 37 females), one to four year (17 riales: 7 females) and over 55 years(19 males: 15 females), and higher for females in the 15-34 years age bracket(12 female: 10 male). 3. Utilization, per two month period, was highest in August-September (19 percent of toal), 4 and lowest in the coldest and least busy months, December and January (14 percent). 4. The average charge per visit was W780; average payment was W686 (88% of the charge). The charge increased in proportion to the distance between the patient's home and the clinic: D Zone; W 1,108, C Zone; W 1,030, B Zone; W 970, A Zone; W769. 5. Medical charge by sex and age distribution, was higher for males in all but the less than one year and one to four year brackets, charges(W1,145) weme highest in the 35-54 years age bracket, lowest (W 401) in the less than one year bracket. 6. Disease patterns, by major division, showed highest frequency (16.8%) in the infection and parasitic category, folinwed, consecutively, by Respiratory System, Digestive System and Skin, Nail, Hair and Subcutaneous Tissues. 7. The most common cause of clinic visits based on the WHO Classification, was Pulmonary Tuberculosis, followed by, consecutively, Common TCold and Preventive Inoculation and Vaccination. 60.3% of the total clinic visits involved the twenty most common disease of the WHO List. 8. Medical charge, by disease category, was highest for 'Other disease of GUT' (W927), followed by Pulmonary Tuberculosis (W921), and lowest for Preventive nIoculation and Vaccinatioir (W259). 9. Continous visits were most common for Pulmonary Tuberculosis, Hypertensive Diseases and Peptic Ulcer and Complications.

Five cases of ameloblastoma considered to be originated from the wall of the odontogenic cysts are reported. Histologic characteristics and diagnostic criteria are aimed to study in differentiation of ameloblastoma arising in odontogenic cysts from odontogenic cysts accompanying with reactive epithelial proliferation, and the literature is reviewed. This study can propose that the ameloblastic change and downward growth of epithelial cells lining the cysts are the most important and characteristic findings of the ameloblastoma derived from odontogenic cysts. In addition, the intraluminal proliferation of epithelial cells in plexiform pattern is also significant.

MRI and arthrograms were used to diagnose the disc displacement of temporomandibular joint, but most of these trials focused on the anterior disc displacement. The discs could be displaced laterally or medially and in some case this sideway displacement may play a role as a main problem of temporomandibular disorder. In this study, 45 patients(31 unaffected sites, 59 affected sites) and 20 asymptomatic volunteers' sagittal and coronal MRI views were reviewed, then some results were found as follows 1. In sagittal plan, anterior disc displacements were found 15% in normal sites, 45% in unaffected sites and 69% in affected sites. 2. In coronal plan, sideways disc displacements were found 15% as medial in normal, 6% as medial and 13% as lateral in unaffected, 8% as medial and 14% as lateral diaplacement in affected sites. 3. In asymptomatic sites involving unaffected sites, medial disc displacements(11.3%) but in symptomatic joints, lateral disc displacements(13.8%) were prevalent. 4. The sideways disc displacement were observed 10.1% as medial and 2.9% as lateral dispalcement without and 9.8% as medial and 16.4% lateral dispalcements with anterior disc displacement. And, the coronal views of MRI were beneficial to evaluate the sideways disc displacement. Further studies may be needed on evaluation of the relations between sideways displacements and clinical symptoms or the treatment results.
