An explorative and descriptive study in order to determine the effect of family structure and other socio-demographic variables on health behavior, belief, locus, and value and utilization of public health service was carried out. Data were collected from 1,653 subjects randomly sampled in three areas, Seoul, Kyunggi province, and Cheju province. From Seoul 849 subjects were selected, 397 subjects Kyunggi, and 407 subjects from Cheju, respectively. Self-reporting questionaires were administered during the period from March to June, 1992. The major findings were as follows: 1) The subjects visited herb-doctor's at irregular intervals mainly to have tonic medicine prepared. They preferred herb-doctor's rather than with doctors at clinics and hospitals. Statistically significant difference was found among the regions studied (p<0.05). 2) The reason for visiting hospitals was primarily for treatment of diseases. They preferred hospital because they felt that the hospitals offer much highly reliable treatment services as well as medical accessibility. For the purpose of hospital utilization, statistically significant differences existed among sex, educational level, family type and region. However, no significance was found among sex, educational level, and region (p<0.05). 3) The subjects utilized general hospitals mainly for diagnosis and treatment of diseases. They preferred general hospitals because of their much better facilities and reliability. Statistical significance was found among sex, educational level, and region (p<0.05). 4) The subjects visited dentist at irregular intervals basis. They visited once half a year or three to four months. their purpose of visit was mainly for diagnosis and treatment of diseases. Statistical significance differences were found among educational level, region and economic standard (p<0.05). 5) Whenever their illnesses were mild and the pharmacies was located in nearby they visited to pharmacies. They visited once a month and patient medicines. Statistically significant differences were found among sex, educational level and region (p<0.05). 6) The subjects believed that herb medicine was quite efficacious for treatment of some diseases, particularly by information handed down through time-honored tradition and experience. However, they recognized that the efficacy of folk medicine can vary with type and severity of diseases. Statistical significance was among sex, educational level, region and economic standard (p<0.05). 7) The reason why subjects believed that pray and superstition are effective for treatment of certain type of diseases, particularly in neuropathy, was the belief in God's almighty. Statistically significant differences were found among sex, educational level, regions and economic standard (p<0.05). 8) Most of subjects under same condition preferred western medicine because they believed that it is more scientific and prompts in showing therapeutic effect. Statistical significance was not found in the choice of type of public health service among, regions. But significant differences were found among sex, educational level and region (p<0.05). 9) The subjects looked for pharmacy if they thought the symptom was mild. However, they visited hospitals for chronic disease and general hospitals for emergency treatment. Statistical significances were found among educational level, region and economic standard (p<0.05). 10) Although most of students wanted to have a healthy life as for the component of health standard and value, they think that they are not healthy (p<0.05). As for the health behavior, significant difference was found in the proportion of smoking and drinking between educational level and region (p<0.05). The health locus was affected by educational level, and health behavior was influenced by region, sex and educational level. The utilization of type of public health service was influenced by family type and region, and health belief by region and educational level, and the health values by region and economic standard respectively, most of correlation showed statistical significance. Among them, the highest correlation was seen between locus of control and external/internal locus of control, which is quite obvious. The correlation between health belief and behavior was the next highest, but still low (0.343). All the other variables are low but significant except only a few of those. These findings indicate that health education should be incorporated into the curriculum so as to develop desirable health habit, and ability of self-control in accordance with their growth stages. A systematic and scientific understanding on the herb/folk medicine is needed, and greater reliability of the utilization of public health services are is still required. Health policy for equal distribution of health service throughout the country along the hierarchical health service system and complementary mutual assistance and cooperation among various health organizations are also required.

Acne vulgaris is a chronic inflammatory condition characterized by comedo, papule, cyst, nodule and postinflammatory hyperpigmentation. Meanwhile, it is also induced by adverse event of drugs. Among them, acneiform folliculitis is a side effect of epidermal growth factor receptor (EGFR) inhibitor, which is an anticancer agent, and its incidence may occur in upward of 75 ~ 100% of cases. The main method of acne vulgaris treatment is oral antibiotics, retinoids, topical medication and so on. However, it is limitation that teratogenicity caused by retinoids and antibiotic resistance increased by using antibiotics. In this study, we aimed to evaluate the clinical efficacy and safety of topical recombinant human (rh) EGF in treating facial acne vulgaris. Twenty three Koreans (age: 10 ~ 29 years) with mild to moderate acne vulgar participated in the study and applied topical rhEGF cream (trouble control EGF) with 3 products (trouble control clarifying cleansing foam, trouble control all-clear filling toner, redroll calming moisture) on their face twice daily for four weeks. Several assessment methods were applied: Acne lesion counts score by investigator's global assessment, efficacy and satisfaction score by subjects. Skin sebum output level, hydration level and redness level were also measured at each visit. At the final visit, skin sebum level, transepidermal water loss, skin redness statistically decreased and acne lesions (comedone, papule) were statistically reduced. No severe side effects were observed during the study. In conclusion, topical rhEGF seems to be an effective and safe adjuvant treatment option for mild acne vulgaris.

Neuroleptic malignant syndrome(NMS) is an acute, potentially fatal, idiosyncratic reaction to neuroleptic medication. Early recognition and intensive care are crucial. An important issue is whether NMS will recur after initial recovery and subsequent use of neuroleptic medication. The authors presented with a male adolescent who had suffered a bipolar disorder manic episode and been taking clozapine after recovering from MNS. He had been admitted into a psychiatric ward once before and similarly diagnosed. On the second admission, he showed muscle rigidity, autonomic instability, mild fever, severe diaphoresis, and altered mental status on the fourth hospital day following a haloperidol injection. He was diagnosed with NMS, according to the clinical signs and laboratory data. After the use of antipsychotics was discontinued, he was moved to intensive care unit and given dantrolene. His condition began to improve about 48 hours after the onset of NMS. Due to manic behavior, he returned to the psychiatric ward. On the 21 st hospital day, clozapine was administered to counter the manic symptoms. The final dose was 350mg and showed good remission signs without further recurrence of NMS.

The Bioconcentration factor (BCF) is used as an important criterion in the risk assessment of environmental contaminants. Also it can be used as indicator of biomagnification of environmentally hazardous chemicals through food-chain as well as a tool for ranking the bioconcentration potential of the chemicals in the environment. This paper reports the measured BCF value on Chlorothalonil in Carassius auratus(goldfish), under steady state, and examined correlation between the BCF value and the partition coefficient or acute toxicity or physicochemical properties. Carassius auratus(goldfish) was chosen as test organism and test period were 3-day, 5-day. Experimental concentrations were 0.005, 0.01 and 0.05 ppm. Chlorothalonil in fish tissue and in test water were extracted with n-hexane and acetonitrile. GC-ECD was used to detecting and quantitating of Chlorothalonil. Partition coefficient was determined by stir-flask method. $LC_{50}$ was determined on Chlorothalonil. Carbaryl and BPMC. The obtained results were as follows. 1. It was possible to determine short term BCFs of Chlorothalonil through relatively simple procedure in environmental concentrations. 2. $BF_3$ of Chlorothalonil in concentration of 0.005, 0.01 and 0.05 ppm were 2.1866$\pm$0.23446, 3.5269$\pm$0.23517, 10.2045$\pm$0.18053 and BCFs were 6.6543$\pm$0.55257, 6.9774$\pm$0.02500, 23.4576$\pm$2.06884, respectively. 3. Chlorothalonil concentration in fish extract and BCFs of Chlorothalonil were increased as increasing test concentration and prolonging test period. 4. Fate of test-water concentration on Chlorothalonil was greater than that of control-water con-centration. It is considered that greater fate of test-water concentration on Chlorothalonil is due to hydrolyzing nitrile group under the mild condition and substituting chloro group by some aromatic compounds in test water. 5. Determined logP of Chlorothalonil was 2.80. And determined $LC_{50}$ of Chlorothalonil in time of 24, 48, 72 and 96 hr were 0.1684, 0.1402, 0.1400, 0.1352(mg/l) respectively. And $LC_{50}$ of Carbaryl in above times were 19.918, 18.635, 18.466, 18.12(mg/l) respectively. $LC_{50}$ of BPMC were 10.248, 9.166, 9.087, 8.921(mg/l) respectively. 6. It is suggested that the BCF of Carbamates depend on partition coefficients. But BCF of Chlorothalonil, organochlorine pesticide, would be strongly influenced by steric, electronic effect of substituents than partition coefficient.

Background: Spontaneous pneumomediastinum is an uncommon disorder with few cases reported. It usually occurs in young males and has benign self-limiting course without any apparent concomitant factor. It is seen after intrathoracic pressure changes leading to alveolar rupture. The clinical experiences of two medical centers were reviewed to aid in optimal management. Material and Method: Retrospective review between March 2003 and August 2010 with spontaneous pneumomediastinum patients was performed. Result: 24 patients were identified with a diagnosis of spontaneous pneumomediastinum. These 24 patients were comprised of 18 men and 6 women with mean age 18.9 years (range 10 ~ 33). The major initial complaints were chest pain (79.2%), throat pain (62.5%), and subcutaneous emphysema (41.7%). The triggering events were exercise (16.7%), coughing (12.5%) and vomiting (12.5%). No apparent triggering event was noted in 54.2% of patients. In all cases, chest radiograph and computed tomography was done. Diagnostic computed tomography was required in 25%. White blood cell counts and C-reactive protein (CRP) were checked, and their initial mean values were $9,790{\pm}3,240/{\mu}L$ Land $1.31{\pm}1.71mg/dL$, final mean values were $5,440{\pm}1,665/{\mu}L$ Land $0.72{\pm}0.73mg/dL$, respectively. 23 patients were admitted (average $5.0{\pm}1.8$) and the symptoms were self-limiting in all cases without complications. Conclusion: Spontaneous pneumomediastinum is a benign condition with mild inflammatory signs that often presents with chest or throat pain. Secondary causes must be ruled out to avoid an unfavorable outcome with less invasive study. Because of very rare complications and recurrence, outpatient basis and shortened hospitalization may be feasible.

De Grouchy syndrome or Distal 18q- is a genetic condition caused by a deletion of genetic material within chromosome 18, and the deletion involves the distal section of 18q. It causes a wide range of medical and developmental concerns. Congenital orthopedic anomalies, cleft lip and palate are relatively common. People with distal 18q- are often small for their age. Most individuals with distal 18q- fall in the mild to moderate range of intellectual disability. Strabismus and nystagmus, changes in the optic nerve as well as colobomas are also fairly common. People with distal 18q- frequently have conductive and/or sensorineural hearing loss. At present, treatment for distal 18q- is only symptomatic. This article presents a case report: Caries treatment of a 4-year-old female patient with de Grouchy syndrome under general anesthesia. The special considerations of dental care, especially caries treatment for the patient with de Grouchy syndrome are discussed.

Hydrocephalus is a condition in which the volume of cerebrospinal fluid in the cerebral ventricles is abnormally elevated. Hydrocephalus patients may show macrocephaly and delayed development. Ventriculoperitoneal shunt is the most commonly used treatment but ventriculoatrial shunt is another treatment option. This report discusses the dental management process employed for a 7-year, 6-month old patient with ventriculoperitoneal shunt-treated hydrocephalus. This patient showed dental caries on the deciduous molars, facial swelling, macrocephaly and delayed development. Pulpectomy was performed on the deciduous molars under nitrous oxide sedation and mild protective stabilization. This patient did not appear to have any specific complications until the latest follow-up and was scheduled for the management of overall oral hygiene, development of permanent teeth, and craniofacial asymmetry through periodic follow-up. During dental treatment of shunt-treated patients, care should be taken to avoid applying excessive force to the catheter running along the patient's neck to prevent the displacement of the catheter. A referral to a neurosurgeon is recommended for patients with ventriculoatrial shunts for prophylactic antibiotics. As hydrocephalus patients grow, they may show craniofacial asymmetry or differences in the calcification of the permanent teeth, and require periodic oral and craniofacial assessment.

The main aim of this study was to investigate the potential of wood charcoal on removing furan compounds (5-hydroxymethylfurfural (5-HMF), furfural) known as fermentation inhibitors in sugar hydrolysates obtained from supercritical water treatment of lignocellulosic biomass. For this aim, model hydrolysate was prepared, and removal rates of sugars or furan compounds depending on wood charcoal concentration and treatment time were calculated and analyzed in comparison with the case of activated carbon. 0.5, 1, 2, 4, 8, or 12% (w/v) of wood charcoal or activated carbon was loaded into the model hydrolysate, containing glucose, xylose, 5-HMF, and furfural, and treatment was conducted for 1, 3, 6, 12, or 24 h. After treatment, removal rates of 5-HMF and furfural gradually increased as wood charcoal concentration or treatment time increased, and over 95% of 5-HMF and furfural were removed at 8% of wood charcoal concentration and 3 h of treatment time, while the loss of sugars (< 2%) was hardly observed. On the other hand, in the case of activated carbon treatment, removal rates of 5-HMF and furfural were over 95% at mild condition (activated carbon concentration: 8%, treatment time: 1 h), but over 10% of glucose and xylose were removed. Therefore, considering sugar production and further process applied sugar, the wood charcoal treatment of sugar hydrolysate was more effective for removing furan compounds and maintaining the sugar yield.

Lymphocytic interstitial pneumonia(LIP) is an uncommon condition in which the alveolar septa and extra-alveolar interstitial space are markedly expanded by small lymphocytes, plasma cells and histiocytes. Chest radiographs generally show nonspecific patterns with the most common pattern showing bibasilar reticular or reticulonodular infiltrates. Hilar or mediastinal lymphadenopathy and pleural effusions are usually absent. We encountered a 42-year-old female patient who was admitted to hospital because of exertional dyspnea and palpitation. The chest X-ray showed an enlarged bilateral hilar shadow and diffusely increased bronchovascular markings in both lung fields. The chest CT showed diffuse nodular infiltrations with mild septal thickening and combined patchy ground glass opacity in both lungs, and conglomerated mediastinal and bilateral hilar lymphadenopathy. A diagnosis of LIP was made from the tissue pathology taken by a thoracoscopic lung biopsy. The patient showed clinical and radiographic improvement after 3 months of treatment with prednisolone. We report a case of LIP presenting as diffuse nodular interstitial infiltrations with multiple mediastinal and bilateral hilar lymphadenopathy.

The purpose of this clinical study is to assess whether calcium hydroxide as an intracanal medication affects post-treatment pain in teeth especially odontogenic pain which comes from inflammation of the pulp and periradicular tissues when compared with no intracanal medication. From 213 patients who has been treated 237 root canals due to significant pain (moderate-to-severe) we recorded their age, sex, treated tooth, degree of pain, pre-operative states of the tooth. We classified patients into 2 test group; Group 1 (not gain intracanal $Ca(OH)_2$), Group 2 (gain intracanal $Ca(OH)_2$). Through the survey from the patients, we let them write down the occurrence and degree of post-treatment pain in 4hours, 2days, 7days after treatment as none, mild, moderate or severe. The followings were evaluated ; the overall incidence of flare-ups, the overall incidence of post-treatment pain in each group at each time period , the incidence of post-treatment pain in each group at each time period as related to pre-operative states of the teeth These were compared statistically with Chi-square analysis (p < 0.05). Under the condition of this investigation, no difference was observed in the incidence of post-treat-ment pain between the two groups. Therefore, $Ca(OH)_2$ as intracanal medication had no effect on preventing or decreasing the post-treatment pain.
