The purpose of this study was to determine the incidence of malnutrition among patients on admission to hospital, to monitor changes in their nutritional status during hospitalization, and to determine the factors which might affect changes in nutritional status. The subjects for the study were patients who were admitted to general medicine for more than one week. Patients suffering from cardiovascular. renal disease, or dehydration were excluded. Nutritional assessment of the patients was performed on admission and nutritional status was reassessed one week and two weeks after admission. The nutritional assessment tool consisted of subjective history taking and anthropometric measurements. Biochemical measurements were performed only on admission. For anthropometric assessment : patients' body weight, subcutaneous skinfolds thickness, % of body fat, body mass index, and lean body mass were measured using caliper or Bio impedance Analyzer. Factors which might influence current nutritional status, like dietary intake, anorexia, nausea, vomiting, diarrhea, sleep disturbance, and number of days of NPO for diagnostic examinations were analyzed. The results are as follows : 1. Of the 59 patients who were studied, 61% were male and 39% female. The nutritional status of all of the 59 subjects was reassessed one week after admission, but it was only done for 22 subjects at two weeks. 2. The anthropometric measurements. including weight body mass index, lean body mass, body fat. and skin fold thickness. were all significantly decreased at one week after admission compared to the values at admission. On the other hand, two weeks after admission, only body weight and abdominal skinfolds thickness were decreased. 3. The subjects reported anorexia for an average of two days, sleep disturbance for two days, and no food intake due to diagnostic test for one day. In the second week of hospitalization, almost none of the patients complained of gastrointestinal symptoms or sleep disturbance except anorexia. Food consumption which was measured based on rice intake was 60% of the food served during the first week of hospitalization, and 66% during the second week of hospitalization. 4. There was no correlation between the subjective nutritional assessment and anthropometric assessment. 5. There was no statistical significance in anthropometric measurements among the patients with various diseases whereas sleep disturbance and no food intake due to various diagnostic test was prominent in patients with gastrointestinal diseases.

Objective: Miniscrew-assisted rapid palatal expansion (MARPE) is a means for expanding the basal bone without surgical intervention in young adults. Here, we assessed the differences in dental, alveolar, and skeletal measurements taken before (T0), immediately after (T1), and 1 year after (T2) MARPE. Methods: Twenty-four patients (mean age, 21.6 years) who had undergone MARPE and cone-beam computed tomography at T0, T1, and T2 were included. Changes in the following parameters were compared using paired t-tests: intercusp, interapex, alveolar, nasal floor, and nasal cavity widths; inclination of the first molar (M1) and its alveolus; and thickness and height of the alveolar bone. A linear mixed-effects model was used to determine variables that affected periodontal changes in the M1. Results: MARPE produced significant increases in most measurements during T0-T2, despite relapse of some measurements during T1-T2. The alveolar thickness decreased on the buccal side, but increased on the palatal side. The alveolar crest level at the first premolar moved apically. Changes in the thickness and height of the alveolar bone were affected by the corresponding initial values. Conclusions: MARPE can be used as an effective tool for correcting maxillomandibular transverse discrepancy, showing stable outcomes 1 year after expansion.

The soft tissue covering of the face plays an important role in facial esthetics, speech and other physiologic functions. Thus, it is recognised by all clinical orthodontists that success of orthodontic treatment is closely related to the changes in soft tissues of the face. The purpose of this study was to evaluate the changes of bony and soft tissues in prepost treatment of Angle's Class III malocclusion. The sample consisted of 18 males and 37 females, pretreatment age of 9 years to 11 years. For this study 11 landmarks were plotted, 14 linear length, 4 soft tissue thickness and 2 angles were measured. The obtained results were as follows; 1. In the linear measurements of bony and soft tissue changes, A, Is, Ss, Ls and Li were located more anteriorly in both sexes. However Si and B showed more remarkable anterior movement in female. 2. In the comparison of the changes of the soft tissue thickness, Ss and Li in male subjects and Ss in female subjects increased. 3. In the degree of correlation between changes in the soft tissue profile and changes in the skeletal profile, Is: Ls, Il: Li and B: Si in both sexes had significant correlations. However A:Ss had remarkable significant correlation in female. 4. There were significant correlations between change in ${\angle}A$ and change in ${\angle}B$ in all sexes. 5. There were little correlation between changes in distance difference of Is and Ii and Change in distance difference of Ls and Li in all sexes.

Despite of the successful clinical performance of implants, it is still lacking of the knowledge of changes in implant occlusion. The purpose of this study was to evaluate the changes of infraocclusal contact after clinical occlusal function of implant. Twenty patients(38 implants) were recalled during 10 months after placement of implant prosthesis. Occlusion changes were investigated at placement, placement 1 months, 4 months and 10 months serially with silicone bite material and T-Scan II sensor. Bony changes were also evaluated with periapical radiographs. The changes of silicone thickness and T-Scan II sensored areas were statistically analyzed with repeated measured ANOVA and the Scheffe's post-hoc test at the 95% significance level. The following results have been made based on this study: 1. Alveolar bone loss was within 0.20mm and it was generally concluded within physiologic level. 2. There were no statistically significant differences in the thickness changes of silicone material at 1 month and 4 months of occlusal function. However, there was statistically significant difference at 10 months of occlusal function (p<0.05). 3. There was no statistically significant difference in changes of occlusal contact area in T-Scan II at 1 month and 4 months of occlusal function, but there was statistically significant difference at 10 months of occlusal function (p<0.05). Conclusively, as time goes by, implant occlusion to be formed infraocclusion was to be far close and increased occlusal contact. However, it was not observed destructive bone resorption in periapical radiographs and any other side effects.

PURPOSE: The purpose of this study was to determine the impact of stable and unstable surfaces on abdominal muscle thickness and changes in trunk muscle thickness in accordance with breathing methods during bridging exercises. METHODS: Bridging exercise on a stable surface, bridging exercise on an unstable surface, bridging exercise using a drawing-in maneuver on a stable surface, bridging exercise using a drawing-in maneuver on an unstable surface, bridging exercise using bracing on a stable surface, bridging exercise using bracing on an unstable surface. In sequence, the muscles' thickness was measured three times before and after each exercise, and the measured value was averaged. RESULTS: There were significant differences in internal oblique and transversus abdominis muscles' thickness in the drawing-in maneuver in both stable and unstable surface (p<0.05). There were no significant differences in external oblique muscle's thickness in the bridging exercise in both stable and unstable surface. The type of surface did not have a significant influence on the abdominal muscles' thickness. CONCLUSION: As a result of the study, the drawing-in maneuver had a greater effect than bridging or bracing maneuver on muscle thickness. We suggest that drawing-in maneuver will be more effective in a person with a weak abdominal muscle.

A hybrid finite element analysis was used to analyze the influence of ring gear rim thickness and spline number on the static properties of a planetary gear system with manufacturing errors. Both of these parameters affected the bearing force and critical stress. The effect of changes in the rim thickness on the load sharing between the gears depended on the type of manufacturing error. Ring flexibility improved the load sharing between planetary gears only in systems with planet tooth thickness or planet tangential errors; for other types of error, ring flexibility worsened the load sharing. To improve load sharing, rim thickness and spline number should be controlled within a specific range. The minimum rim thickness limit should be determined considering not only the critical stress but also the load sharing. The effect of the ring gear boundary condition was more apparent in a system with errors than in a normal system.

In this paper, a non-contact method of evaluating the thickness reduction in an aluminum sheet caused by corrosion and friction using SH-EMAT (shear horizontal, electromagnetic acoustic transducer) is described. Since this method is based on the measurement of the time-of-flight and amplitude change of guided waves caused from the thickness reduction, it provides information on the thinning defects. Information was obtained on the changes of the various wave features, such as their time-of-flight and amplitude, and their correlations with the thickness reduction were investigated. The interesting features in the dispersive behavior of selected guided modes were used for the detection of thinning defects. The measurements of these features using SH waves were performed on aluminum specimens with regions thinned by 7.2% to 29.5% of the total thickness. It is shown that the time-of-flight measurement provides an estimation of the thickness reduction and length of the thinning defects.

The e-coating to inhibit induced corrosion can deposit a coating not only on the exterior surface but also on the inside of whole metallic components of body-in-white (BIW). But it is difficult to deposit paint films on the inside area because metallic components are multi layered. It may cause shortness of e-coating thickness. The only way to properly verify e-coating thickness is by performing the use of tear-down prototypes. When paint films' thickness is inadequate, a structural modification on each metallic component is needed. Verification of the thickness improvement for a structural modification requires much manual effort and leads to increasing development time. Recently, the simulation technology has been developed to predict the e-coating thickness in e-coating field. By applying the simulation to BIW, improvement in paint thickness quality and shortening of development period are expected. The paper explains a validated solution that allows simulating the effect of design changes to the e-coating thickness and current density, thereby delivering results within a time frame of a few days.
