Iron deficiency anemia is a worldwide public health problem relevant to unsound nutritional practice. While the prevalence of iron deficiency anemia is very common among pregnant women, appropriate nutritional service programs to improve the iron status are lacking in Korea. In an attempt to develop a nutritional screening tool to separate the high-risk subjects of iron deficiency, we carried out a nutritional survey for 115 Korean pregnant women whose gestational age ranged from 13 to 24 weeks. Each subject was interviewed with questionnaires for general characteristics and dietary habits. Food intake was measured by 24-hour recap method and 2 day record. Fasting blood was drawn for measuring hemoglobin and serum ferritin. It appeared that half of the pregnant women belonged to the anemia group and had insufficient dietary habits to provide adequate amounts of dietary iron. The first gravida and the working women had better hematological iron indicators than the second or more gravida and the housewives. It also appeared that women who had bigger family size and lower BMI in pre-pregnancy had poorer iron status. Among the food consumption habits, fruit dependent dietary habit was related to poor iron status. Sufficiently consumed green leafy vegetable and appropriate amount of food before morning sickness were positive factors of iron stares. Our results indicated that parity, BMI, current job, family size, food habits including consumption of fruits, green & yellow vegetables, and food habits before the onset of morning sickness are significant factors to contribute the Fe deficiency anemia during pregnancy.

Objective : The purpose of this study was to investigate the necessity of occupational therapist's involvement in patient discharge planning, the areas that should be considered for discharge screening and planning, and to provide the basic data required for the development of a discharge assessment tool. Methods : We conducted an online questionnaire survey of 60 occupational therapists who were working at medical institutions and had agreed to participate in the study. The questionnaire was composed of 36 questions regarding the general characteristics of the current discharge planning process and the necessity of discharge assessment and planning. Descriptive statistics, an independent t-test, and a one-way ANOVA were conducted using SPSS 20.0. As for the post-hoc test, Scheffe's test was used. Results : The awareness of occupational therapist's role in discharge planning and the necessity of a discharge assessment tool were high, but the occupational therapist's awareness of discharge-related knowledge was low. The difficulties in discharge planning showed high response rate in the absence of adequate fee-for-service in the patient interview and assessment and the lack of team approach and appropriate assessment tools for discharge planning. The high-needs areas for evaluation during discharge were fall risk and BADL, and the low-needs areas were well-being and functional level prior to onset. Conclusion : This study is expected to provide preliminary information necessary for the development of a discharge assessment tool for effective discharge planning.

The purpose of this study attempted to collect basic data for development of an integrated self-management program for cancer survivors who completed cancer treatment. Self-management programs are divided into symptom management and physical activity management. Symptom management includes fatigue, sleep disturbance, pain, depression and anxiety. PubMed, CINAHL and EMBASE were used for searching guidelines. Based on the guideline quality evaluation, the final 8 guidelines were analyzed. The structured table was used to extract the screening subjects, timing, contents, subjects for comprehensive assessment and contents, and summarized contents related to the physical activity and exercise in non-pharmacological approach. As a result, after the completion of cancer treatment, all cancer survivors should be screened regularly using reliable and validated tools. In the case of fatigue, physical activity was recommended as the primary intervention, but it was recommended for other symptoms as adjuvant therapy. Therefore, Cancer survivors should be encouraged to be active in their physical activity, and maintain the moderate intensity physical activity as long as they have no complication related to the cancer treatment. Motivation strategies for physical activity need to be developed and applied.

There have recently been an increasing number of reports claiming that the periodontal disease, the most typical oral disease, is closely associated with various systemic diseases such as cardiovascular disease. Therefore, it is imperative to explore the methods that can ensure effective and cost-effective monitoring of periodontal disease in specific population groups, as well as individuals in the electronic medical record environment. However, traditional periodontal examination methods, such as periodontal probe, are considerably demanding and time-consuming for dental specialists, and furthermore, cause the risk of bacteremia as they are invasive procedures. Thus, the objective of this study was to validate the capability of new method for screening the periodontal disease using the self-reported questionnaire for periodontitis which is the non-invasive procedure to replace radiography.

Pregnant women in South Korea are a highly risk group fur iron deficiency anemia. Previous studies indicated that the 24-hour recall method was insensitive in distinguishing iron deficiency anemic women from normal women. This method is also impractical to when used at community health centers where no public health dietitians are employed. The objective of this study was to develop a convenient tool to evaluate the usual iron (Fe) intake of pregnant women. The study participants were 115 pregnant women (age 23 to 37 years) at gestational stage of 13 to 24 weeks. Anemic subjects were classified on the basis of their serum ferritin < 12.0 ${\mu}$g/L and hemoglobin < 12.0 g/dL levels. Food frequency questionnaires with 46, 29, and 15 commonly consumed food items were used to measure the usual intake of iron of the subjects. Hemoglobin and serum ferritin were measured from fasting blood samples. Nutrients intake was assessed on three consecutive days using the 24-hour recall method and the food record method. The iron index score calculated using the food frequency method showed a significantly positive correlation with iron intake for the three days dietary intake. The iron index showed a significantly difference (p < 0.05) between the normal and anemic groups. However, there was no significant difference in the iron intake between the anemic and the normal women as measured by the 24-hour recall and food record method. Our study indicated that the 29-food items questionnaire could be used as a screening tool to identify poor dietary intake of iron. (Korean J Community Nutrition 8(2) : 160170, 2003)

In this study, fluorinated ethylene propylene (FEP) nanoparticle as an adhesive for fabricating a three-dimensional multilayered microfluidic device was studied. The formation of evenly distributed FEP nanoparticles layer with 3 ㎛ in thickness on substrates was achieved by simple spin coating of FEP dispersion solution at 1500 rpm for 30 s. It is confirmed that FEP nanoparticles transformed into a hydrophobic thin film after thermal treatment at 300 ℃ for 1 hour, and fabricated polyimide film-based microfluidic device using FEP nanoparticle was endured pressure up to 2250 psi. Finally, a three-dimensional multilayered microfluidic device composed of 16 microreactors, which are difficult to fabricate with conventional photolithography, was successfully realized by simple one-step alignment of FEP coated nine polyimide films. The developed three-dimensional multilayered microfluidic device has the potential to be a powerful tool such as high-throughput screening, mass production, parallelization, and large-scale microfluidic integration for various applications in chemistry and biology.

Cirrhosis is a consequence of chronic liver disease characterized by replacement of liver tissue by fibrosis, scar tissue and regenerative nodules leading to loss of liver function. Liver Cirrhosis is most commonly caused by alcoholism, hepatitis B and C, and fatty liver disease, but has many other possible causes. Some cases are idiopathic disease from unknown cause. Abdomen of liver Computed tomography(CT) is one of the primary imaging procedures for evaluating liver disease such as liver cirrhosis, Alcoholic liver disease(ALD), cancer, and interval changes because it is economical and easy to use. The purpose of this study is to detect technique for computer-aided diagnosis(CAD) to identify liver cirrhosis in abdomen CT. We experimented on the principal components analysis(PCA) algorithm in the other method and suggested texture information analysis(TIA). Forty clinical cases involving a total of 634 CT sectional images were used in this study. Liver cirrhosis was detected by PCA method(detection rate of 35%), and by TIA methods(detection rate of 100%-AGI, TM, MU, EN). Our present results show that our method can be regarded as a technique for CAD systems to detect liver cirrhosis in CT liver images.

The radical scavenging activity measurement system linked with liquid chromatography (LC) is a useful tool for identifying the radical scavenging active compound in a sample composed of numerous compounds such as plant extracts. Using this system, DPPH and ABTS radical scavenging activity were measured on extracts of Ulmus pumila cortex, which is known as an herbal medicine with antioxidant activity. Mass spectrometry (MS) was performed on the identified radical scavenging active compounds to identify the four components estimated to be procyanidin B2, procyanidin B3, catechin-7-O-β-D-apiofuranoside, and catechin-5-O-β-D-apiofuranoside, respectively. In order to compare the relative contents between extract samples, multiple reaction monitoring (MRM) mode analysis conditions were set for the four compounds in order to examine the possibility of comparing the content of radical scavenging active compounds in Ulmus pumila cortex extract using LC-MS/MS. As a result of the relative content comparison, it was found that the higher the ethanol concentration of the extraction solvent, the higher the content of radical scavenging active compounds. As with the results of measuring the radical scavenging activity of each extract, it was confirmed that the content difference of three of the compounds (all except the compound estimated as procyanidin B3) was not significantly observed in the extracts with an ethanol concentration of 50% or more.
