This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

A wafer rolling etching system for the silicon bulk micromachining has been designed and fabricated. The silicon diaphragms were anisotropically etched in a 24.5 weight percent KOH solution. Compared to the conventional KOH etching systems, pyramidal hillocks, and wave-shaped structures on the etched surfaces were greatly reduced by using this system. After etching for time of 438 minutes, the average etched depth and the etch-rate were measured to be 537μm and 1.22μm/min, respectively. The average etching uniformity of etching depth was 0.87% in 5-inch wafer. Our results showed that the wafer rolling method enhanced etch uniformity and etch rate.

Electromyography(EMG), one of the earlest neurophysiological diagnostic tool, is a important technique on dental research and dental practice. In this review, physiological principles underlying EMG and the origin of EMG are discussed. I discuss many of problems affecting interpretation, including normalization, processing of EMG signals. Various EMG methods are also presented and their principles are discussed. The EMGs recorded with surface electrodes are usually more susceptible to artifacts than those did with intramuscular electordes. It is possible, however, to make useful recording with the surface electrtode from large superficial muscle if appropriate precautions are observed. Intramuscular electrodes may be preferred for recording the activity from small peripheral muscles or muscles located deep within the body. In temporomandibular dysfunction patients, EMG is useful for evaluation of treatment as well as diagnosis.

Costume has expressed the life style and influence on natural and social environment, The purpose of this study is to understand changes of hair style and millinery life in the west. The data used in this study included in the literature on this subject. The research results can be summarized as follows. 1. A hair style of ancient times was frizz or chignon or dyed hair style. Sometimes, they wore wigs of false hair, or put on a head kerchief. Millinery has been not worn until then. 2. In the middle ages, the hat serve to symbolize the social rank or authority or religion. Turbans were worn which concealed the hair. The hair style were large stuffed rolls over which the wimple was sometimes draped. These stuffed rolls were also used to form some shapes of the hennin, principally the heart-shaped and circular cone style. The hennin was brought to France by Isabella of Bavaria in the latter part of the fourteenth century and its vogue lasted a hundred years. There were many styles of the hennin, invariably draped with a veil, floating or with wired edge. They became so extravagant in size that I found it necessary to regulate the height according to the socal position of the wearer.

As economic uncertainty increases, the financial risk for enterprises is spreading. Based upon these economic situations, this paper proposes a model for measuring the enterprise risk. This model is named TRI(Total Risk Index), which consists of six sectors; financial indicator risk, real price risk, competition risk, customer risk, finance policy risk, and operation risk. The risk of financial institutions can be measured through VaR(Value-at-Risk). But non-financial institutions such as manufacturing companies can possess various types of risk, so this risk can be measured through TRI. The result of measuring TRI for Korea representative enterprises shows that their TRI comprises half of their own capital. This result signifies that the enterprise risk is high. This model can be utilized as Early Warning System for non-financial companies through historically measuring TRI.

To study the pseudocholinesterase acticity and its clinical significance in patients with acute organophosphate poisoning, Authors checked the serum cholinesterase activity in 49 normal subjects and 31 acute organophosphate poisoned patients. The results were followings. 1. The mean pseudocholinesterase activity f normal subjects was 1271 IU/L in male and 1131 IU/L in female. The total mean cholinesterase activity was 1209/ IU/L. 2. The pseudocholinesterase activity of patients were significantly reduced compare to normal. 22 patients(73%) were below 10% of normal, 6 patients(20%) were between 10-20% of normal and only 2 patients (7%) were between 20-50% of normal. 3. As a whole there was more depressed cholinesterase activity in patients with comatous and drowsy mentality, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference between three groups. 4. The pseudocholinesterase activity in patients with respiratory failure was more depressed than without respiratory failure, but there was no statistically significant difference presented. 5. The mean arterial blood gas checked on arrival was pH 7.386, PaO?? 66mmHg, PaCO?? 38mmHg 02 Saturation 91%. There was noted no statistically significant correlation between pseudocholinesterase activity and these parameters. 6. The pseudocholinesterase activity on the 1st day of admission was 5.7% of normal and progressively increased during admission. On the 14th day of admission, the pseudocholinesterase activity was 35.5% of normal and it takes 20 days to reach 50% of normal. Authors concluded that serum cholinesterase activity of acute organonphosporus poisoned patients were markedly depressed and progressively increased during admission. As a whole the pseudocholine-sterase activity seemed to be related to the clinical findings but no statistically significant difference was found.

An integrated silicon pressure sensor has been designed, fabricated and tested. The signal conditioning circuits were designed to include calibration and temperature compensation of output voltage through trimming of diffusion and ion-implanted resistors. Before trimming of resistors, the compensation parameters such as pressure sensitivity, temperature coefficient of pressure sensitivity, temperature coefficient of piezoresistors and pressure sensitivity of piezoresistors were measured. Then offset voltage, span, and temperature coefficients of offset voltage and span were calibrated by trimming of resistors. The measured output voltage met our design specification and simulation value above room temperature. But, the measured output voltage at -30°C deviated from our design specification and simulation value because the offset voltages were found to vary randomly as a function of temperature.

Vocal cord dysfunction (VCD) is a respiratory disorder characterized by the abnormal adduction of the vocal cords upon inspiration, expiration, or both, leading to a diverse array of acute obstructive airway signs and symptoms (wheezing, chest tightness, shortness of breath, and cough). VCD frequently mimics or confounds asthma. Misdiagnosis as asthma has led to inappropriate treatment, most notably with high-dose corticosteroids. Mistaken for anaphylaxis or angioedema, VCD has led to intubation and tracheostomy. VCD should be suspected in patients who are treated aggressively for asthma but continue to experience dyspnea. The diagnosis of VCD is made from direct visualization of the vocal cords during an attack. Inspiratory, anterior vocal cord closure with a posterior glottic chink is seen. On pulmonary function testing, a pattern of "saw-toothing", or fluttering of the inspiratory limb, representing fluctuations in the abnormal cord motion is seen in VCD patient. Treatment includes discussion of the diagnosis with the patients, discontinuing unnecessary medications, using of a helium-oxygen mixture in acute attack. Speech therapy and psychotherapy are the mainstays of long-term treatment. Here in we report a case of VCD in company with asthma.
