This study was undertaken to better understand the utilization practice of mass media, and to suggest the food and nutrition information provided to mass media by researchers on the utilization, satisfaction, and demand of acquired nutrition information. The provision of cooking methods and menu introduction related to the training subjects at the same time as when food nutrition information is discusse by mass media, including TV and internet, would be helpful to enhance the acquisition and utilization rates of the information among the public. It was found that food nutrition information should be activated for general public using objective and professional public institutions or web-pages so as to resolve dissatisfaction levels felt by the public with regard to exaggerated claims. At the same time, it is required to continue to maintain interesting and various information supply highlighting the characteristics of mass media when performing food nutrition information. In addition, it is also necessary for media practitioners concerned to investigate thoroughly and improve any inconvenient factors that the public experiences when they receive the nutrition information through the mass media.

Purpose: To investigate body compositons and bone mineral density(BMD) in college women and to find the relationship between them. Method: From January to March of 2001, BMD at four parts(forearm, lumbar, femur and whole body), body mass index(BMI), body fat mass(BFM), lean body mass(LBM) and body fat percentage(%Fat) were measured with the Dual Energy X-ray Absorptiometry. Other physical characteristics were measured with a scale, a height measurer, and questionnaires. Result: Grouping by the BMI, 43.2% showed low weight, and 5% over weight. When applying the percent Fat, 43.8 % was diagnosed as obesity group. The fact indicate that a majority of college women have unbalanced body composition with high percent Fat, compared to their body weight. Assessing the BMD with the WHO standards, 91.4～95.7% of the BMD of forearm and whole body was normal. But, 40.3% and 33.1～43.9% showed osteopenia at lumbar and femur, and 104 %, 0.7～7.2% showed osteoporosis. The BMD at all parts showed significant correlation each other(r=.29～.89, p=.001～.000). Body weight and BMI showed correlations to with BMDs at all parts of the body(r=.19～46, p=.025～.000; r=18～.45, p=.039～.000). But the percent Fat had a correlation with only femur neck BMD(r=.19, p=.024). Conclusion: This study showed a majority of healthy college women were exposed to the risk for osteoporosis. Additional study is required to develop nursing interventions to remove the risk factors of osteoporosis. In particular, the acquisition of balanced body composition is necessary, increasing body weight and BMI through the increase of LBM, not through the quantitative increase of BFM.

A method of ultrahigh performance liquid chromatography coupled to high resolution mass spectrometry (UPLC-HRMS) was established for characterization of the lipid profile of Skipjack tuna. Over 300 lipid molecular species were identified through cross-acquisition in both positive and negative ion mode. Phospholipids (PLs) were dominant in Skipjack tuna. Lysophosphatidylethanolamine (LPE), phosphatidylethanolamine (PE), lysophosphatidylcholine (LPC) and phosphatidylcholine (PC) were the main lipid molecular species in PLs, accounting for 89.24% of the total PLs. The ratio of sphingolipids (SLs) and glycerolipids (GLs) were considerable, accounting for 12.30% and 13.60% of the total lipids respectively. Ceramide (Cer) was the main lipid molecular species of SLs, accounting for 64.96% of total SLs, followed by sphingomyelin (SM), accounting for 25.45% of total SLs. Ether diglycerides (ether DG) were the main lipid molecular species of GLs (97.83%). The main fatty acids (FAs) are unsaturated fatty acids (UFAs) in Skipjack tuna. Besides, a new FAs class branched fatty acid esters of hydroxy fatty acids (FAHFA) was detected, together with the FA. The active lipids identified in this study can be used to evaluate the nutritional value of Skipjack tuna.

Recently, the system of the industry demands quick and accurate measurement for the mass production and high quality. Also, we need to improve the accuracy to decrease the failure rate in automatic assembly processing and improve the confidence, durability and the compatibility of parts. To answer this tendency and requirement, we have developed many accrate measuring instruments and methods. In this paper, we develop the whidows program using the DSP board(TMS320C25) which is used the data acquisition and the Visual C $^{++}$ , a windows programming language. We perform the measurement, analysis and output process in GUI(Graphic User Interface)environment. By using system, we will save the time required for the hand-worked measurement and avoid the useless iterative measurement. Furthermore, we expect to improve the productivity through automotive quality control in manufacturing process.s.

Many structural evaluation procedures of road and airfield pavements use the Falling Weight Deflectometer (FWD) as a critical element of non-destructive deflection testing. FWD is a trailer mounted device that provides accurate data on pavement response to dynamic wheel loads. A dynamic load is generated by dropping a mass from a variable height onto a loading plate. The magnitude of the load and the pavement deflection are measured by a load celt and geophones. And database concerning pavement damage should be enhanced to analyze loss of thickness asphalt layer caused from the plastic deformation of pavement structure, such as cracking or rutting. The prototype FWD is developed, which consists of chassis system, hydraulic loading system, data acquisition and analysis system. This system subsequently merged to from automation management system and is then validated and updated to produce a working FWD which can actually be used in the field.

As chemotherapy and other sophisticated treatment strategies evolve and the number of survivors of long-term childhood cancer grows, the long-term complications of treatment and the cancer itself are becoming ever more important. One of the most important but often neglected complications is osteoporosis and increased risk of fracture during and after cancer treatment. Acquisition of optimal peak bone mass and strength during childhood and adolescence is critical to preventing osteoporosis later in life. However, most childhood cancer patients have multiple risk factors for bone mineral loss. Cancer itself, malnutrition, decreased physical activity during treatment, chemotherapeutic agents such as steroids, and radiotherapy cause bone mineral deficit. Furthermore, complications such as growth hormone deficiency and musculoskeletal deformity have negative effects on bone metabolism. Low bone mineral density is associated with fractures, skeletal deformity, pain, and substantial financial burden not only for childhood cancer survivors but also for public health care systems. Thus, it is important to monitor bone health in these patients and minimize their risk of developing osteoporosis and fragility fractures later in life.

Fermentation parameters were estimated by use of a vent gas analyzer coupled to a computer data acquisition system in cultivation of Phellinus linteus WI-001, pro-ducer of polysaccharides known to have potent anticancer activities. Oxygen uptake rate(OUR), a critical indicator of the cells activities, was calculated by applying oxygen mass balance. In addition, by dividing the oxygen uptake rate hy the total oxygen consumed, on-line estimation of the cells specific growth rate was successfully done. It was also possible to estimate cell concentration directly bt use of oxygen-cell yield($Y_{x/o}$ ) which was obtained based on a correlation between cell growth and total oxygen consumed.

This study was performed to apply the more rapid and accurate sample preparation, and the high selectivity and sensitivity of the analyte detection by gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS). QuEChERS (quick, easy, cheap, effective, rugged and safe) method was validated for 49 agrochemicals in the CORESTA Agrochemical Advisory Committee guide and amenable to GC-MS/MS determination. In QuEChERS method, the effects of sorbents (PSA, $C_{18}$ and GCB) and matrix of the analytes in tobacco types (flue-cured, burley and oriental) were investigated. MS/MS acquisition provided high specificity and selectivity for agrochemicals and low limit of quantification. QuEChERS by using PSA alone and the matrix-matched standards gave good recoveries and RSD values in three types of tobaccos. QuEChERS method was no needed to be complex clean-up procedure and would be used as the fast and easy method for agrochemical residue analysis in tobacco.
