  • The study aim was to examine the effect of sensory responses of subjects after 6-month dietary sodium reduction with the aid of nutritional education. Fourteen female college students voluntarily restricted their sodium intake for 6 months, during which time they received nutritional education on the low sodium diet. As a control group, 10 students, whose anthropometric measurement, sodium intake behavior, and blood pressure were not different from those of the experimental group, were maintained on a normal diet. For the sensory responses of subjects, the salt taste perception and pleasantness for graded (0.15-1.3%) NaCl solutions were measured by a 9-point hedonic scale. The optimum sodium concentration, urinary sodium excretion, and blood pressure were measured. All the measurements were done at the beginning and end of the experiment. The sensory evaluation revealed an absence of any difference between the two groups in salt taste perception and pleasantness responses at the beginning. After 6-month adaptation, the experimental group subjects showed higher responses to low NaCl solution (0.15, 0.3, 0.5%) in salt taste perception and pleasantness evaluation while the control group subjects exhibited the opposite response. The optimum sodium concentration was reduced from 105.6 mmol to 80.7 mmol (p = 0.015) and the urinary sodium excretion was also reduced from 1,398 mg to 906 mg (p = 0.041) only in the experimental group. Systolic blood pressure was significantly reduced in the experimental group, although there was no correlation between the urinary sodium excretion and blood pressure. The optimum sodium concentration was negatively correlated with the urinary sodium excretion (r = 0.418, p = 0.053), indicating that adaptation to low sodium diet can reduce sodium intake. Further study on the individual responses of subjects on a low sodium diet by periodical evaluation may provide useful data for setting the duration needed to stabilize a lowered appetite for sodium.

  • Routine chest radiography is generally imaged by high voltage technique but some radiological technologists use low voltage for imaging. High voltage is usually said between $120\;kV{\sim}140\;kV$. Some RTs like using heavy filtration but others seldom like using it. However which is better for use calcium tungustate film screen system or ortho system and high contrast film or wide latitude c-type film for the exculusive use of chest radiography. We could not make a decision which is ideal method for use. In my opinion any method is not always exellent for chest radiography. In my experiments that I had at Kaken hospital in Japan last year I expect to keep the balance between image quality and diagnostic range and to reduce radiation dose for patients. My experiments are as follows. 1. We have looked into system characteristics(speed and contrast) in accordance with kVp($80{\sim}140$) and added filter($no{\sim}1/16\;VL$) in three screen film systems(BX3+CRONEX4, SRO750+MGH, SRO750+MGL). 2. We have looked into skin dose and film dose with same D=1.8 lung field density in accordance with kVp($80{\sim}140$) and added filter($no{\sim}1/16\;VL$) in three screen film systems. 3. We have compared with the evaluation between correlation of physical image quality(MTF) and optical diagnostic capability. Result are follows. 1. Speed of BX3+CRONEX4 became higher in accodance with kVp and thickness of filter but speed of ortho system was not as like regular system. Thicker filter diminished the speed over 100 kV range in SRO750+MGL. In case of SRO750+MGH speed of 1/16VL filter was looked into lower than speed of 1/4VL filter. Sensitivity of ortho system depends on tube voltage and added filter. 2. Skin dose has been detected $225\;{\mu}Gy{\sim}66\;{\mu}Gy$ in BX3+CRONEX4 from 80 kV, no filter to 140 kV, 1/16VL filter. SRO750+MGH could reduce the patient dose $1/2{\sim}1/3$ level in comparison to that of BX3+CRONEX4. 3. The higher kV was the worse MTF became the thicker filter was the worse MTF became too. MTF of BX3+CRONEX4 was detected better than MTF of SRO750+MGH but SRO750+MGH's optical detectability of small lesion in lung field came out better than that of BX3+CRONEX4. Conclusion Recently routine chest radiography is generally imaged by high voltage but it seems to be there are some questions in using of film screen combination. In high voltage chest radiography the subject contrast will come down that means latitude become wider. In this case if we select the low contrast film screen system(C or L type) the film contrast will fall down extremly and detectability of small lesion will be deteriorated. Wide latitude C, L type film has a merit of high detectability on mediastinum. Furthermore high contrast film screen system has the advantage to keep the high contrast in low density region as like mediastinum and heart shadow. Therefore in low subject contrast high voltage chest radiography we would rather choose the high contrast film screen system(H type) I think. From a view point of patient dose detectability of mediastinum and lung field. The optimum technical facter was found out 120 kV, 1/16VL filter : BX3+CRONEX4, 140 kV, 1/4VL filter : SRO750+MGH, 100 kV, 1/4VL filter : SRO750+MGL.

  • In order to gain information on the plant characteristics of high yielding paddy from the point of view of mineral nutrition and to learn more about soil conditions under which high yields are produced a number of soil samples collected from the field experiment carried out in The City College of Seoul were analysed. In addition, a laboratory experiment carried out to support the field experiment was also analysed. Results obtained are as follows: 1. Generally, the higher the yield of paddy, the higher is the potassium content in flag leaves, whereas the reverse is true for the content of Ca and Mg in the leaves. From these facts it can conceivably be said that the high yielding paddy should absorb a large quantity of potassium and a lesser quantity of calcium and magnesium in the reproductive stage. 2. Leaves of paddy which produced yields over 600kg/10a (a comparatively high yield in the experiment) contained 30-35mg/100g of potassium, less than 25me/100g of calcium, and 10me/100g of magnesium which brings the ratio of $K/{\sqrt{Ca+Mg}}$ over 5. 3. Correlation studies indicated a remarkable relationship between the paddy yield and exchangeable potassium in soil samples taken after harvesting. A similar relationship was observed between the yield of paddy and $K/{\sqrt{Cae+Mge}}$ ratio of the soil samples. 4. A regression between yield of padcy (Y) and exchangeable potassium (Ke) or $K/{\sqrt{Ca+Mg}}$ in soil samples taken after harvesting was shown to be; Y=183.95+2135.86Ke $$Y=352.45+3114.454\;K/{\sqrt{Ca+Mg}}$$ 5. The regression between exchangeable potassium (Ke) in soil samples taken after harvesting and the amount of lime (L) and potassium (P) to be applied is; $$Ke=0.1246+0.00007037L+0.004444P+0.000004444L{\cdot}P$$.

  • Objectives: The most important differential point of follicular carcinoma from adenoma is capsular invasion or angioinvasion of follicular cells. Serial sections for examination of levels of tumor margins are necessary to watch the invasion. However, the interpretation of capsular invasion or angioinvasion is sometimes not feasible on the routine staining of tumor tissue. The aim of this study is to evaluate the clinical significance of expressions of $p27^{KIP1}$, MIB-1, bcl-2 and p53 in differential diagnosis of follicular adenoma and carcinoma. Materials and Methods: 16 cases of follicular carcinoma and 26 cases of follicular adenoma were entered on study of immunohistochemical stains for $p27^{KIP1}$, MIB-1, bcl-2 and p53. In carcinoma cases, correlation between the above markers, patient's age, tumor size, infiltration pattern and metastasis was studied. Results: $p27^{KIP1}$ labelling index (LI) of follicular carcinoma and adenoma was $4.89{\pm}6.92$ and $14.52{\pm}9.17$, respectively, but there was no significant difference between adenoma and carcinoma (p=0.2560). MIB-1 LI of carcinoma and adenoma was $4.11{\pm}3.89$ and $0.80{\pm}0.75$, respectively, and MIB-1 LI was significantly higher in carcinoma (p=0.0000). bcl-2 expression was seen in 2(12.5%) of 16 carcinoma cases and 130(50.0%) of 26 adenoma cases, and bcl-2 expression rate was higher in adenoma than in carcinoma(p=0.014). In one adenoma and one carcinoma case, p53 expression was noted. In follicular adenoma with atypia compared to adenoma without atypia, lower $p27^{KIP1}$ LI, higher MIB-1 LI and lower bcl-2 expression rate were seen. In follicular carcinoma, MIB-1 LI was significantly higher in invasive carcinoma(p=0.045) and was relatively increased in tumors larger than 3.0cm, showing angioinvasion and distant metastasis. But $p27^{KIP1}$ LI was higher in cases over 40 years old(p=0.008) and with conspicuous capsular invasion. There were no positive correlations between expressions of MIB-1, bcl-2 and p53. Conclusion: MIB-1 labelling index and bcl-2 expression could be helpful for differential diagnosis of follicular adenoma and carcinoma, but p53 showed very low expression rate and no significance in differential diagnosis. $p27^{KIP1}$ labelling index reveals decreasing tendency in carcinoma compared with adenoma, MIB-1 LI was considered as a poor prognostic marker in follicular carcinoma, but $p27^{KIP1}$ LI was higher in carcinoma cases over 40 years old with showing conspicuous capsular invasion. Further study for the significance of $p27^{KIP1}$ labelling index in follicular neoplasms is necessary to evaluate diagnostic value of follicular carcinoma.

  • Purpose: In this study, we evaluated the effects of training for survival prediction of terminally ill patients in terms of medical professionals' confidence, accuracy and knowledge of survival prediction. Methods: Twenty-nine participants completed a self-administered questionnaire where they scored their confidence, accuracy and knowledge of survival prediction before and after the training session. The training was provided in July 2009 at a university hospital located in Gyeonggi province, Republic of Korea. The participants were instructed by a professor of family medicine specialized in hospice palliative medicine to predict survival of a case using the palliative prognostic score and objective prognostic score. The training was provided in the form of a PowerPoint presentation for 40 minutes. Results: Participants' confidence in survival prediction significantly increased from $4.00{\pm}1.73$ ($mean{\pm}SD$) (0~10, visual analogue scale) to $5.83{\pm}1.71$ after the training (P<0.001). Before training, participant's level of confidence significantly correlated with their age (P=0.04). The training significantly improved the correlation between the confidence level and the number of terminal cancer patients whom they have experienced (P=0.005 before training, P=0.017 after training). Participant's accuracy in survival prediction also significantly improved from 14 of 29 (48%) to 27 of 29 (93.1%) (P<0.001). The change in knowledge of survival prediction was too small to be statistically analyzed. Conclusion: After training, the confidence and accuracy scores significantly improved. Further study with a greater number of participants is needed to generalize this finding.

  • The purpose of the study was to develop an eating habit checklist for screening elementary school children at high risk of energy overintake. Dietary habits, food intake, anthropometric data were collected from 142 children (80 boys and 62 girls) in the 4th to 6th grades of elementary schools. Energy intake, fat intake, and percentage of Estimated Energy Requirement (%EER) were used as indices to detect the risk of energy overintake of the children. Pearson correlation coefficients were calculated between dietary habit scores and energy overintake indices in order to select questions included in the checklist. TV watching during the meal, meal speed, meal amount, overintake frequency, eatingout frequency, snack frequency, frequency of eating Ramyun or fast foods showed significant correlations with energy overintake indices. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 7-item checklist with test results from 0 to 13 points was developed, and those with equal or higher than 5 points were diagnosed as a risk group of energy overintake. Among our subjects 13.4% was diagnosed as the risk group. Mean energy intake of the subjects in the risk group and the normal group were 2,650 kcal and 1,640 kcal, respectively. However, there were no significant differences of Index of Nutritional Quality (INQ) of the other nutrients except eating fiber between the risk group and the normal group. This checklist will provide a useful screening tool to identify children at high risk of energy overintake.

  • Emotional awareness is the image of a person is represented by different tendencies. Currently, the emotion computing to objectively evaluate the emotion recognition research is being actively studied. However, existing emotional computing research has many problems to run. First, the non-objective in emotion recognition if it is inaccurate. Second, the correlation between the emotion recognition is unclear points. So to test the regularity of image sensitivity to the need of the present study is to control emotions in the computing system. In addition, the screen number of the emotion recognized for the purpose of this study, applying the method of objective image emotional computing system and compared with a similar degree of emotion of the person. The key features of the image emotional computing system calculates the emotion recognized as numbered digital form. And to study the background of emotion computing is a key advantage of the effect of the James A. Russell for digitization of emotion (Core Affect). Pleasure emotions about the core axis (X axis) of pleasure and displeasure, tension (Y-axis) axis of tension and relaxation of emotion, emotion is applied to the computing research. Emotional axis with associated representative sensibility very happy, excited, elated, happy, contentment, calm, relaxing, quiet, tired, helpless, depressed, sad, angry, stress, anxiety, pieces 16 of tense emotional separated by a sensibility ComputingIt applies. Course of the present study is to use the color of the color key elements of the image computing formula sensitivity, brightness, and saturation applied to the sensitivity property elements. Property and calculating the rate sensitivity factors are applied to the importance weight, measured by free-level sensitivity score (X-axis) and the tension (Y-axis). Emotion won again expanded on the basis of emotion crossed point, and included a representative selection in Sensibility size of the top five ranking representative of the main emotion. In addition, measuring the emotional image of a person with 16 representative emotional score, and separated by a representative of the top five senses. Compare the main representative of the main representatives of Emotion and Sensibility people aware of the sensitivity of the results to verify the similarity degree computing emotion emotional emotions depending on the number of representative matches. The emotional similarity computing results represent the average concordance rate of major sensitivity was 51%, representing 2.5 sensibilities were consistent with the person's emotion recognition. Similar measures were the degree of emotion computing calculation and emotion recognition in this study who were given the objective criteria of the sensitivity calculation. Future research will need to be maintained weight room and the study of the emotional equation of a higher concordance rate improved.

  • The purpose of the study was to develop an eating habit checklist for screening elementary school children at risk of inadequate micronutrient intake. Eating habits, food intake, and anthropometric data were collected from 142 children (80 boys and 62 girls) in the $4^{th}$ to $6^{th}$ grades of elementary schools. Percentage of Recommended Intakes (RI) and Mean Adequacy Ratio (MAR) of six micronutrients; vitamin A, riboflavin, vitamin C, calcium, iron, zinc, and the number of nutrients the children consumed below EAR among the six nutrients were used as indices to detect the risk of inadequate micronutrient intake. Pearson correlation coefficients were calculated between eating habit scores and inadequate micronutrient intake indices in order to select questions included in the checklist. Meal frequency, enough time for breakfast, regularity of dinner, appetite, eating frequencies of Kimchi, milk, fruits and beans showed significant correlations with indices of inadequate micronutrient intake. Stepwise regression analysis was performed to give each item a different weight by prediction strength. To determine the cut-off point of the test score, sensitivity, specificity, and positive predictive values were calculated. The 8-item checklist with test results from 0 to 12 points was developed, and those with equal or higher than 6 points were diagnosed as high-risk group of inadequate micronutrient intake, and those with 4 or 5 points were diagnosed as moderate-risk group. Among our subjects 14.1% was diagnosed as high-risk group, and 30.3% as moderate-risk group. The proportions of the subjects who consumed below EAR of all micronutrients but vitamin C were highest in the high-risk group, and there were significant differences in the proportions of the subjects with intake below EAR of all micronutrients except vitamin B6 among the three groups. This checklist will provide a useful screening tool to identify children at risk of inadequate micronutrient intake.

  • Japan's mechanic animation is widely known throughout the world. 1952년, Japan's first mechanic animation and the first TV animation, , has been popular since it's creation in 1952. Atom, a big hit at the time, has influenced many people. Japanese mechanic animations convey their unique traits and world view to the public In this paper, we are going to discuss the change of the Japanese mechanical design through comparison of the mechanical design, which has been booming since the 1990s in Japan; and the . I expect the results of this analysis to depict Japanese culture and thought reflected in animation, which is a good indication of worldwide cultural view of animation. unexpectedly influenced the Japanese animation industry after it screened in 1995, and there are still people constantly reinterpreting and analyzing it. This is the reaction of the audience to anticipate the mystery and endless conclusions of the work itself. The design elements of Evangelion are distinguished from other mechanical objects. Mechanic design based on human biotechnology can overcome limitations of machine and make you feel more human. The pilot 's boarding structure, which can contain human nature, is reinforced in the form of an enterprising plug, and the attitude of excavation makes humanity more prominent than a straight robot. Thus, pursues a mechanic design that can reflect human identity. can be selected as the mechanic animation of the 80's, and the "Neon Genesis Evangelion" of the 90's shows it with a completely different design. By comparing the mechanical design of two works, therefore, we examine the correlation between the message and the design of the work. presents the close relationship between the identity of the mechanical design and the contents. I would like to point out that mechanical design can be a good example and theoretical basis for the future.
