Objective : The purpose of this study was to analyze non-invasive treatments and drooling assessment methods in children with cerebral palsy and developmental disabilities, who drool. Methods : This study searched two hundred papers published in 2005-2019. Forty-four papers were selected based on their abstract and title, and ten papers were finally selected following a secondary search. Results : The PEDro Scale of the selected papers was high with an average of seven points. As a result of analyzing the overall trends, the study participants were primarily patients with cerebral palsy, and recently, the therapeutic intervention of oral sensory exercise was more actively studied than behavioral modification. Studies of behavioral modification and oral sensory exercise intervention methods were found to have differences in participant age and, cognitive level, number of participants, research design, treatment time, and duration. Studies to confirming the frequency and severity of the drooling measurement method were found to be the main factor. Conclusion : This study analyzed typical behavioral modification and oral sensory exercise interventions as examples of non-invasive therapeutic interventions for children with cerebral palsy and developmental disabilities and provided information to help select appropriate therapeutic intervention methods when planning non-invasive therapy using behavioral modification and oral sensory exercise therapy.

The studies were conducted to know the relationship between $\beta$-amlyase activities and hardiness for the germinated seedlings of, winter wheat varieties which were classified with eye estimated cold resistance in field as, susceptible, moderate and resistant. These varieties were tested in continued five days from germination in four replicated split plot design. For the measurement of $\beta$-amylase, improved A. K. Balls method (2) was employed. Result obtained will be summarized as follows. 1. Tested varieties showed highly significant differences in $\beta$-amylase activity, while no differences were obtained between dates after germination. 2. Winter hardy varieties, Yukseung ＃3, Chin Kwang and Suwon＃85 showed higher amylase activities than the moderate hardy varieties, Jukdalma, Kangdosinryuk and Norin ＃4, while lower activities were measured in susceptible varieties, Norin ＃6, Kangdo and Norin＃12. 3. With measurement of $\beta$-amylase activity, rurther detail classification to cold resistance is seemed available than eye-estimating in the field condition. 4. In accordance with testing dates, amylase activities were not so clear on 1st, 2nd, 4th and 5th days from germination, while clear differences were found on 3rd day from germination. 5. Amylase activity obtained on 3rd day after germination is considered easy and effective method to estimate cold resistance of wheat varieties with a classification standard.

Hardness and elasticity for SurichwijuIPyun(Korean rice cake supplemented with Surichwi) made with various levels of Surichwi(O∼40%) boiled in 1% sodium bicarbonate added water were decreased by increasing additional rate of Surichwi, but adhesiveness and cohesiveness didn't show constant increase or decrease. Guminess and chewiness showed significant differences by decreasing additional rate of Surichwi. As a results of sensory evaluation of Surichwiiulpyun, Julpyun supplemented with 20fs Surichwi showed the most favorite tendency in color, flavor and overall acceptability. Textural characteristics of Surichwijulpyun supplemented with 20 and 30% Surichwi in storing at 20$^{\circ}C$ showed less change than those of 0 and loft group. Gumminess and chewiness showed similar trend to hardness, and there were significant differences in additional rate of Surichwi and storage time.

This study was conducted to determine the effect of a mixture of two water-soluble dietary fibers, psyllium husk and glucomannan, on serum lipids, fecal fat excretion and body fat. Twenty one female Sprague-Dawley rats were randomly assigned into three groups (control, pair-fed control and test group) and fed a high saturated fat (20% lard) diet (control diet) or a test diet (psyllium husk and glucomannan added to the control diet at the level of 0.9% and 0.68%, respectively) for 8 weeks. Pair-fed control rats were allowed to eat the amount of diet consumed by test group the preceding day. The body weight gain and food efficiency ratio of test group were significantly lower compared with these of control group. The mean values of body weight gain and food efficiency ratio were lower in test group than in pair-fed control group, but the difference was not significant. There were no differences in food intake. The dry weight and water content of feces and fecal fat excretion were markedly greater in test group than in control groups. Serum total cholesterol and triacylglycerol levels were significantly lower in test group than in two control groups.1'he rats of two control groups had higher body fat contents than that of test group. These results indicate that the combination of the two water-soluble dietary fibers, psyllium husk and glucomannan, can be used as a potent lipid-lowering agent in individuals consuming high saturated fat diet.

In order to improve the thermal stability of wood plastic composites (WPC), thermal degradation behavior of WPC in this study was investigated by the addition of wood flour and fire retardant after hybridization of wood flour and ammonium polyphosphate (APP) into polypropylene (PP) matrix. Thermal degradation behavior of all formulations was analyzed with thermogravimetric analyzer under nitrogen environment at heating rate of $10^{\circ}C/min$. As the thermal degradation temperature of wood flour is lower than that of PP, char layer formed by the wood flour decreases the speed of heat transfer to PP. In addition, the char layer increases the 2nd thermal degradation temperature and decreases the 2nd thermal degradation speed. The WPC treated with APP increases the 1st and 2nd degradation temperatures. In the case of WPC with high loading level of wood flour, the 1st thermal degradation temperature and 2nd thermal degradation rate were increased by the addition of APP, and then the amount of remnants at high temperature was increased by the increase of the APP loading level. In the case of WPC treated with APP, the amount of the remnants at high temperature was increased with the increase of wood flour content from 10 wt% to 50 wt%, indicating that char formation of the APP and wood flour occurred at the same time, resulting in high thermal stability effect by the increase of wood flour content.

Calyx-end browning in sweet persimmon (Diospyros kaki) fruits is the postharvest disorder during the storage and shows different proportions by the cultivars. This study was to evaluate fruit texture characteristics at harvest and to learn how browning in fruits affects the cell structures in different cultivars. Persimmon cultivars included 'Fuyu', 'Jiro', 'Uenishiwase', 'Daiandangam', and 'Ro-19', which were harvested at the end of October in 2003 and investigated after 100 days storage. Fruit texture varied with different cultivars. 'Jiro' and 'Ro-19' fruits did not have browning symptoms while 'Daiandangam' fruits had approximately 80% browning of them. There were no visual differences for the cell structure in fruit peels between fruits without browning, such as 'Jiro' and 'Ro-19', and fruits with browning, such as 'Fuyu', 'Uenishiwase', and 'Daiandangam'. The most outer layers in a 'Jiro' fruit peel arranged one to two epidermis which could not induce browning in the tissues, while 'Fuyu' had two to three layers, inducing a browning symptom. Although there were no differences for the tissue structure between browning and normal fruits, browning fruits did not have apparent cell organelle and proceeded degradation of cell walls in the flesh.

Purpose : About 41% of obtained group A streptococci in the 1998 was reported as erythromycin-resistant streptococci in Seoul, Korea. The most common T serotype was T12, followed by T4 and T28. We'd like to monitor the serological changes and antibiotic sensitivity test of Streptococcus pyogenes obtained from the patients with pharyngotonsillitis and invasive diseases from 1999 through 2001. Also, it could be proposed to choose the proper antibiotic selection in the area where the rate of erythromycin-resistant streptococci is high. Methods : From Jan. 1999 to Oct. 2001, 208 isolates of group A streptococci were collected from inpatients and outpatients with pharyngotonsillitis, scarlet fever, and invasive infections in Seoul and Southern part of peninsula. All isolates were serotyped by T-agglutination, minimum inhibitory concentrations(MICs) which were determined by agar dilution methods, according to the guidelines of the National Committee for Clinical Laboratory Standards (NCCLS). Results : The most common T serotype was T12(29.8%), followed by T1(23.1%), T4 (14.9%). T1 was prominent serotype compared with previous year. T serotyping, among 25 isolates obtained from the patients with scarlet fever in Southern part of peninsula mostly, was T12, T1, and T4 in order of frequency. All the isolates tested were susceptible to penicillin, cefprozil, vancomycin, ceftriaxone, and chloramphenicol. However, 23 isolates(14.2%) was resistant to erythromycin and 18 isolates(11.1%) was resistant to clarithromycin. Serotype T12 was found to be the most resistant serotype to erythromycin and/or clarithromycin. Conclusion : High rate of erythromycin-resistant streptococci which surveyed in 1998 were reduced to 14.2% in this study. We should have to further evaluate the reason of decreased resistant strains and consider the resistant strains of streptococci in choosing the antibiotics. There was no serological characteristics according to the types of disease entities. Between the serologic distributions in Seoul and the Southern part of peninsula area are same, we could presume that the serological typing of strains obtained over the country may be not different.

Regional odontodysplasia(ROD) is relatively rare localized developmental anomaly of tooth formation in which hard tissue is affected. The maxilla is typically affected than the mandible, and especially the maxillary left quadrant is the most commonly involved. Females are affected twice as often as males, and there is no association with race. Its etiology remains undetermined, but local circulatory disorders, somatic mutations, virus infections, local trauma, hyperpyrexia, irradiation, metabolic disturbances, and hereditary transmission are considered as possible etiologic factors. The affected teeth are likely to be small, hypoplastic, brown, and grooved. Eruption failure or delay is frequently seen as well as abscess or fistulae formation in absence of caries. Radiographically, there is a lack of contrast between the enamel and dentin, both of which are less radiopaque than unaffected counterparts. Moreover, enamel and dentin layers are thin, giving the teeth a “ghost-like appearance”. The pulp chambers and canals are large, the roots seem like to be short and indistinct. A 2-year-3-month old boy came to the department of pediatric dentistry, Yonsei University, with the chief complaint of delayed eruption and abnormal tooth shape on the lower left quadrant. He was diagnosed as regional odontodysplasia based on the clinical and radiographic findings.

Purpose: The aim of this study was to compare quality of life of long-term survivors after a subtotal or a total gastrectomy for gastric cancer. Materials and Methods: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and QLQ-STO22 questionnaire were used to assess quality of life of 166 patients on their 5th annual follow-ups after gastrectomy for gastric cancer. One hundred twenty-six patients underwent a subtotal gastrectomy and 40 patients a total gastrectomy. Results: The subtotal gastrectomy group revealed a trend to have better quality of life in functional scales (physical, role, emotional, cognitive and social), fatigue, pain, dyspnea, diarrhea and financial difficulties. The total gastrectomy group showed a trend to have better quality of life in the global health status and quality of life, nausea and vomiting, insomnia, appetite loss and constipation. In all scales of the EORTC QLQ-STO22, the subtotal gastrectomy group had a trend to have better quality of life. However these did not reach the statistical significance. Conclusion: Surgeons may not limit the extent of resection concerning long-lasting poor quality of life. Oncologically sound resection is recommended.

This study was performed to compare the differences between total fat area, subcutaneous fat area and visceral fat area according to L1-S1 inter vertebral disc level in asymptomatic Korean patients with non-contrast abdominal CT scan. The location of the maximum fat ratio of the total fat area is the total fat area measured in male L2-3, L3-4, L4-5, female L4-5, and L5-S1. The location showing the maximum fat ratio of the subcutaneous fat area is the subcutaneous fat area measured in male L4-5, and the woman is the subcutaneous fat area measured in L4-5 and L5-S1. The location of the maximum fat ratio of visceral fat area was the visceral fat area measured in L1-2 and L2-3 males, and there was no difference in visceral fat area according to the measured position in females. Although abdominal fat measurement is common at the L4-5 inter vertebral disc level, fat distribution varies widely depending on nationality, race, and gender. Therefore, it is necessary to analyze through the research data which location to choose according to the research purpose, and to mention why the location is appropriate.
