Purpose: The purpose of this study was to examine anger-expression patterns and their association with state and trait anger and physical and psychological health status in health care workers. Method: Four hundred and forty eight nurses, physicians and technicians from a large medical center completed standardized questionnaires of anger, anger-expression patterns and mood. They also had blood pressure, cholesterol, blood glucose and body mass index measured during their annual physical examinations. Data was analyzed using descriptive statistics, independent t-test, chi-square and ANOVA. Results: Subjects showed two major clusters of anger-expression patterns: anger-control and anger-in/out. Subjects with the anger-in/out pattern reported higher state and trait anger and more anxiety, depression and fatigue than subjects with the anger-control pattern. Physical health indicators, however, were not significantly different between the two clusters of anger-expression patterns. Conclusion: Anger-expression patterns are associated with psychological health status but not with physical health status. Anger-expression patterns, however, need to be examined over time to assess their long-term effects on the physical and psychological health status in future studies.

The current scope of diabetic patient education and dietary consultation by hospital dietitians were studied. A questionnare was sent to 54 dietitians in 32 hospitals throughout Korea. The major results are as follows: 1. The frequency of dietary consultation for diabetic patients is of low level: only 14 patients were seen such services at average per month. 2. Only one hospital establishes independent office for dietary consultation for in-and-out patients and in 3 hospitals among 32 hospital dietitians practice regular rounds to visits patients. 3. Consistant patterns and methods to counsel patients were established in 53% of hospitals. In remaining hospitals, teaching methods depend entirely on the individual dietitians. 4. A few hospitals have teaching aids and follow-up systems. 5. Most dietitians want strongly the establishment of independent office for dietary consultation, but its establishment was hindered by the poor system in the hospital administration and lack of preparation in the dietetics.

A brain-computer interface(BCI) system is a communication channel which transforms a subject's thought process into command signals to control various devices. These systems use electroencephalographic signals or the neuronal activity of many single neurons. The presented study deals with an efficient analysis method of neuronal signals from a BCI System using an independent component analysis(ICA) algorithm. The BCI system was implemented to generate event signals coding movement information of the subject. To apply the ICA algorithm, we obtained the perievent histograms of neuronal signals recorded from prefrontal cortex(PFC) region during target-to-goal(TG) task trials in the BCI system. The neuronal signals were then smoothed over 5ms intervals by low-pass filtering. The matrix of smoothed signals was then rearranged such that each signal was represented as a column and each bin as a row. Each column was also normalized to have a unit variance. As a result, we verified that different patterns of the neuronal signals are dependent on the target position and predefined event signals.

One of the most important issues in progressive collapse mechanism of the buildings is evaluation of the collapse distribution in presence of the earthquake loads. Here, collapse propagation is investigated by tracking down the location and type of the collapsed beam and column elements, from the first element to the entire buildings. 6-story reinforced concrete ordinary moment resisting frame buildings with one directional mass eccentricity of 0%, 5%, 15% and 25% are studied to investigate differences among the progressive collapse mechanism of the regular and irregular buildings. According to the results of the nonlinear time history analyses, there are some patterns to predict progressive collapse scenarios in beam and column elements of the similar regular and irregular buildings. Results also show that collapse distribution patterns are approximately independent of the earthquake records.

In Electro-Luminescence Display making process, it is necessary to do high molecule patterning effectively. Recently, one of the most effective way is the patterning method using Ink-Jet head controller. To maximize the effect, it is needed to control each channel of Ink-Jet head and develop that controller. Thus, we implement the Ink-Jet Head Controller which can control the parameters of 128 fire pulses independently, improve the accuracy of patterns more than 100 times previous ones, and apply random patterns.

This study was carried out to investigate the use patterns of traditional fermented soybean products(Jang) in Yangsan city. Two hundred eighty seven housewives living in Yangsan joined this survey practiced by Yangsan City Agricultural Development Center. 49.0% of these housewives graduated from a highschool, and 77.4% is in 30s or 40s. Most(69.3%) of respondents themselves have made Jang at home and the preparation frequency of Jang became higher with getting older. This survey showed that the preparation frequency of Jang in large family living with parents is higher than in nuclear family. The Jang preparation tendency of housewives living in the independent home was higher than that of apartment. Most of respondents replied the preparation method of Jang has been learned from mother or mother-inlaw. On the other hand, in the case of no making Jang at home, they bring it generally from relatives or buy it at the market. And 59.8% of housewives anted to participate in the education of Jang preparation.

To evaluate the diagnostic significance of p16 overexpression in human hepatocellular carcinoma (HCC), we analyzed p16 status and growth inhibitory patterns by p16 overexpression in HCC cell lines having different pRE status. SKHep1 and SNU449 cells show homozygous deletion of p16. The p16 gene in SNU398 cell is inactivated at posttranscription level. Adenovira1-p16 (Ad-p16) infection inhibits the cell growth in Hep3B, SNU398, and SNU449. Failure of growth inhibition in SKHepl results from the low transduction efficiency of adenovirus. The p16-mediated growth inhibition shows G 1 phase arrest in pRE-positive SNU449 but not in pRE-negative Hep3B. These results suggest that therapeutic efficacy of p16 gene might be considered on the transduction efficiency and the toxicity of adenoviral vector. Beside, growth inhibitory effect of p16 could be exerted through either pRE-dependent or -independent pathway.

Fabrication of micro carbon structures and patterns using laser-assisted chemical vapor deposition is studied. Argon ion laser and ethylene were used to grow micro carbon rod through pyrolytic decomposition of the reaction gas. The influence of reaction gas pressure and incident laser power on the diameter and growth rate of the micro carbon rod was experimentally investigated. The diameter of micro carbon rods increases linearly with respect to the laser power but is almost independent of the reaction gas pressure. Growth rate of the rod changes little with gas pressure when the laser power remains below 1W. When the carbon rod was grown at near threshold laser power, a very smooth surface is obtained on the rod. By continuously moving the focusing lens in the direction of growth, a micro carbon rod with a diameter of 28 ${\mu}{\textrm}{m}$ and aspect ratio of 100 was fabricated.

In this paper, we proposed an algorithm which used backtracking method to get time information, and it be modelled DMS (Dynamic Multisection) by feature vectors and time information whic are represented to similiar feature in word patterns spoken during continuous time domain, for Korean Speech recognition by independent speaker using DMS. Each state of model is represented time sequence, and have time information and feature vector. Typical feature vector is determined as the feature vector of each state to minimize the distance between word patterns. DDD Area names are selected as recognition wcabulary and 12th LPC cepstrum coefficients are used as the feature parameter. State of model is made 8 multisection and is used 0.2 as weight for time information. Through the experiment result, recognition rate by DMS model is 94.8%, and it is shown that this is better than recognition rate (89.3%) by MSVQ(Multisection Vector Quantization) method.
