  • This survey was conducted from June 2004 to August 2004, through questionnaires given to 432 women aged ranging from 20 to 50 years, who were living in the Seoul metropolitan area. The questionnaires were designed to determine the physique, level of obesity and dieting survey as well as to uncover which diets were in fashion and their satisfaction degree. Dieting-related knowledge and dieting side effects were also investigated. The results were as follows: In dieting survey, as the age increased, dieting for health reason (52.3%) increased, whereas that for aesthetic reasons (32.6%) decreased (p<0.05). The most effective methods of dieting were exercise (50.2%) and diet (45.0%) regimens. In regards to exercise frequency, 46.5% for none, 23.5% for 1-2 times a week, suggesting that most respondents do not practice exercise for dieting purposes (p<0.05). Major source for dieting was shown to be obtained from relative family or friends (31.7%), newspapers or magazines (29.3%) and internet (14.9%). As the age decreased, information from the latter increased, whereas that from TV program (21.2%) decreased (p<0.05). Reasons for excess weight were bad eating habits (39.6%), lack of exercise (38.3%), pregnancy and childbirth (10.6%). In fad dieting, while organic foods and aerobic exercises scored the highest satisfaction degree among diet and exercise regimens, on the other hand, sauna, steam baths and high temperature half-immersion baths scored the highest among surgery and other special therapies. As the age increased, the satisfaction degree for organic foods such as organic vegetable and high functional boiled cooked rice increased (p<0.05). As the age increased, scores on dieting-related knowledge decreased. Side effects of dieting included dizziness 06.2%) fatigue (15.1%) indigestion/constipation (11.1%) physical weakness 00.5%), loss of concentration (7.8%), dry skin (7.4%) loss of motivation (6.7%). The above results showed that attitude toward dieting among adult women varied with age and in light of the well-being trend, organic foods and aerobic exercises scored the highest satisfaction degree through all age.

  • To understand the dietary culture in Poongki region which was established as Kamrokchon of a folk community, the transmission pattern of the traditional dietary life was investigated by questionnaire to 383 housewives, and the results are as follows : 1) Daily diet : Among 65 traditional main dishes of 6 areas including Kyungsangdo, D’cokguk of Kyungsangdo was consumed most frequently, 87%. General consumption rate based on origin of food was 33.3% of Kyungsangdo, 21.2% of Chungchongdo, 13.1% of Kangwondo, 11.9% of Hwanghaedo, 1.1% of Pyungando and Hamkyungdo, respectively. Among 243 traditional minor dishes, Doenjangjjigye and Kochuchang of Kyungsangdo were most consumed as rates of 91.6%, 89.3%, respectively. General consumption rate based on origin was in order of 38.4% of Kyungsangdo, 19.3% of Chungchongdo, 14.9% of Kwangwondo, 10.4% of Hamkyungdo, 8.7% of Hwanghaedo and 8.3% of Pyungando. 2) Special diet : Among 66 traditional D’ocks, Injeolmi of Hamkyungd was consumed most freguently, 58%. General consumption rate based on origin was in order of 26.3% of Hwanghaedo, 17.6% of Kyungsangdo, 16.1% of Kwangwondo, 16.0% of Hamkyungdo, 13.0% of Pyungando and 11.0% of Chungchongdo. Among 27 cookies, Kangjeong of Hamkyungdo was consumed most frequently 46.7%. General consumption rates based on origin was in order of 55.7% of Hamkyungdo, 22.7% of Kyungsangdo, 2.4% of Pyungando, 5.8% of Kwangwondo, 3.0% of Chungchongdo and 0.4% of Hwanghaedo. Among 19 refresh drinks, Kamju of Kyungsangdo was consumed most frequently, 76.0%. General consumption rate based on origin was in order of 74.3% of Kyungsangdo, 7.8% of Chungchongdo, 6.9% of Hamkyungdo, 5.9% of Hwanghaedo and 5.1% of Kwangwondo. 3) Ceremonial diet : Myyeogguk and Baeksulgi for the 100-Days ceremony and Hynbab and Baeksulgi for the First Birthday were used mainly. For birthday, noodle(59.5%) for lunch besides rice as main dish and Soojeoggwa(37.9%) were served and noodle(30.8%) was used for host. Thirty percent of the varieties used traditionally for Pyehak and 40-50% of the varieties for Jesa(Memorial day) are still prepared currently. 4) Seasonal diet : For Jeolsik(major seasonal diet), the usage rates are as follows : D’ockguk(87%) for Jeongwolchoharu, Ogokbab(77.6%) for Jeongwoldaeborum, Patjuk(72.6%) for Dongji, Samsaeknamul(54.1%) for Chusuk. Relatively high usage rates of Surichi-D’ock(40.5%) for Dano and Mandu(40.5%) for Suddalgumumnal are probably due to the immigrated people from this area and the geographical effect. The consumption rates of Sisik(minor seasonal diet) for Chunghwajeol, Samjinal, Youdooil, Chungyangjeol and Muoil are about 10% and the rates for Chopail and Chilsuk are followed. Gaejang and Nangmyon for Sambok used as a rate of 32%. 5) Others : Table pattern; Table for one person(4.7%), table for two(16.7%), table for several(64.2%), table with chair(14.4%) are used. Serving pattern; All-together style(69.7%), monopoly style(24.0%), personaldish style(6.3%) are used. Cooking ware; Among 95 varieties, Doma and Jangban are used most(62.7%) and Pulmae, Poonju and Budulgori are never used. Nine sorts besides Jeongoltle are used as a rate of less than 1%. About 25% of total subjects were the immigrants from other areas. Some of them were moved in due to Chunggamrok. In conclusion, the usage of the traditional food is thought to be maintained well despite of the rapid change to incustrialized society because the native Kyungsangdo foods are combined with foods from the neighboring Kwangwondo, Chungchongdo and northern area.

  • The purpose of this study was to define the content of requisite human structure and function knowledge needed for clinical knowledge of nursing practice. Subjects of human structure and function were divided into 10 units, and each unit was further divided into 21 subunits, resulting in a total of 90 items. Contents of knowledge of human structure and function were constructed from syllabus of basic nursing subjects in 4 college of nursing, and textbooks published by nurse scholars prepared with basic nursing sciences. The degree of need of 90 items was measured with a 4 point scale. The subjects of this study were college graduated 136 nurses from seven university hospitals in Seoul and three university hospitals located in Chonnam Province, Kyungbook Province, and Inchon. They have been working at internal medicine ward, surgical ward, intensive care unit, obstetrics and gynecology ward, pediatrics ward, opthalmology ward, ear, nose, and throat ward, emergency room, rehabilitation ward, cancer ward, hospice ward, and their working period was mostly under 5 years. The results were as follows: 1. The highest scored items of human structure and function knowledge necessary for nursing practice were electrolyte balance, blood clotting mechanism and anticoagulation mechanism, hematopoietic function, body fluid balance, function of plasma, and anatomical terminology in the order of importance. The lowest scored items of human structure and function knowledge necessary for nursing practice was sexual factors of genetic mutation. 2. The highest order of need according to unit was membrane transport in the living unit, anatomical terminology in movement and exercise unit, mechanism of hormone function in regulation and integration unit, component and function of blood in oxygenation function unit, structure and function of digestive system in digestive and energy metabolism unit, temperature regulation in temperature regulation unit electrolyte balance in body fluid and electrolyte unit, concept of immunity in body resistance unit, and genetics terminology in genetics unit. The highest order of importance according to subunit was membrane transportation in cell subunit, classification of tissues in tissue unit, function of skin and skin in skin subunit, anatomical derivatives of the skeleton subunit, classification of joints in joint subunit, an effect of exercise on muscles in muscle subunit, function of brain in nervous system subunit, special sense in sensory subunit mechanism of hormone function in endocrine subunit, structure and function of female reproductive system in reproductive system unit, structure and function of blood in blood unit, structure of heart, electrical and mechanical function in cardiovascular system unit, structure of respiratory system in respiratory system subunit, structure and function of digestive system in digestive system subunit, hormonal regulation of metabolism in nutrition and metabolism subunit, function of kidney in urologic system subunit, electolyte balance in body fluid, electolyte and acid-base balance subunit. 3. The common content of human structure and function knowledge need for all clinical areas in nursing was structure and function of blood, hematopoietic function, function of plasm, coagulation mechanism and anticoagulation mechanism, body fluid, electrolyte balance, and acid-base balance. However, the degree of need of each human structure and function knowledge was different depending on clinical areas. 4. Significant differences in human structure and function knowledge necessary for nursing practice such as skin and derivatives of the skin, growth and development of bone, classification of joint, classification of muscle, structure of muscle, function of muscle, function of spinal cord, peripheral nerve, structure and function of pancrease, component and function of blood, function of plasma, structure and function of blood, hemodynamics, respiratory dynamics, gas transport, regulation of respiration, chemical digestion of foods, absorption of foods, characteristics of nutrients, metabolism and hormonal regulation, body energy balance were demonstrated according to the duration of work. 5. Significant differences in human structure and function knowledge necessary for nursing practice such as classification of tissue, classification of muscles, function of muscles, muscle metabolism, classification of skeletal muscles, classification of nervous system, neurotransmitters, mechanism of hormone function, pituitary and pituitary hormone, structure and function of male reproductive organ, structure and function of female reproductive organ, component and function of blood, function of plasma, coagulation mechanism and anticoagulation mechanism, gas exchange, gas transport, regulation of respiration, characteristics of nutrients, energy balance, function of kidney, concept of immunity, classification and function of immunity were shown according to the work area.

  • The U.S. government have concerned about food safety over the last two decades. The concept of the continuum, “from farm to table” was created to explore ways to prevent foodborne illnesses in all stages of food systems. On the continuum, consumers were recognized as the last line of defense to prevent foodborne illnesses, and much efforts were made to educate them safe food handling. This research was conducted to investigate infant formula handling and hand-washing behaviors of low-income families, especially parents and guardians of infants. The subject was selected from participants of the Special Supplemental Nutrition Program for Women, Infants, and Children(WIC), a federal program for low-income families in the U.S. Stratified 200 local WIC offices were randomly selected based on the number of WIC participants in each state, and 20 randomly selected WIC participants from each selected office were asked to complete questionnaires. SPSS for Windows was used for statistical analyses including frequency, cross- tabulation, and chi-square analyses. A total of 87 WIC offices returned completed question-naires (N = 1,598), and 492 were parents/guardians of infants. Most respondents were white (51.3%), high school graduates (41.5%) , and participated in WIC>1 yew. Most respondents (80.9%) teamed about food safety from WIC, and only limited number of respondents (10.2%) used the Internet for food safety information. Most respondents stored prepared formula safely (94.6%) and discarded formula left in the bottle after feeding (84.5%) , but fewer used brushes to wash formula bottles (71.3%) and boiled water(15.2%) Chi-square analyses showed respondents in different race/ethnicity had different food handling behaviors. Respondents showed generally good hand-washing behaviors as 94.2% always washing hands after using restroom, 93.2% after touching meat items, and 87.l% before preparing foods. Fewer respondents, however, washed hands after changing baby diapers (77.0%) and touching pets (67.2%). Researchers concluded that WIC education on food safety was effective, as limited food safety education covered during WIC education were followed well (e.g., storing prepared formula and discarding leftover). However, results also indicated that there were many behaviors needed to be reinforced especially to overcome family tradition and culture on food handling behaviors. The WIC may serve as good food safety resources and education agents utilizing mandatory education sessions because the vast amount of food safety information on the Internet was not readily accessible for this low-Income Population.

  • A survey on the children's thought for kimchi intake and practical amount of kimchi consumption were conduction in April of 1995 to get basic information needed for the development of special kimchi for the children. And the effects of nutritional guidance on consumming kimchi was also investigated. Total of 1100 students in 2nd, 4th, and 6th grade from public and private elementary school participated in this survey. The eighty three percent of student think they should eat kimchi mainly because kimchi is good for the health(48.0%) and kimchi is our traditional food(31.8%). However, only 26.5% of children consume more than 5 pieces($4{\times}5cm$) of kimchi per mela and 64.5% consume less than 1~2 pieces. This shows that children's opinion(p<0.001), preference(p<0.001) and actual consumption(p<0.001) for kimchi was found to be very significant. Thus the nutritional guidance is important as much as the development of children's kimchi. Children wanted kimchi which is sweet, mild hot and not too strong in flavor. Ingredients children wanted in kimchi were pear, apple, tangerine, carrot and onion. Children's most favorite foods cooked with kimchi were stir fried kimchi rice and kimchi stew. But children did not like kimchi hamberger, pizza topped with kimchi and rice cooked with bean sprout and kimchi.

  • It is well known now that near infrared spectroscopy (NIRS) is a fast, no destructive, and inexpensive analytical technique that could be used to classify, identify, and authenticate a wide range of foods and food items. Therefore, the main aims of this study were to provide a new insight into the authentication of five strawberry (Fragaria x ananassa) varieties and to correlate them with geographical zones and the propagating methods used. Three weeks plants of five different strawberry varieties (F. x ananassa Duch. cv Camarosa, Seascape, Chandler, F. Chiloensis, and F. Virginiana) were cultivated in vitro first and then transferred to pots with special soil, and grown in a greenhouse at CINVESTAV, all varieties were acquired from California (USA). After 18 months, ten leaves from each variety were collected. Transmission spectra from each leave were recorded over a range of 10, 000-4, 000 cm$-^{1}$, 32 scans of each strawberry leave were collected using a resolution of 4 cm$-^{1}$ with a Paragon IdentiCheck FT-NIR System Spectrometer. Triplicates of each strawberry leave were used. All spectra were analyzed using principal component analysis (PCA) and soft independent modeling class analogy (SIMCA). The optimum number of components to be used in the regression was automatically determined by the software. Camarosa was the only variety grown from the same shoot but propagated by a different method (direct or in vitro). Five different classes (varieties) or clusters were observed among samples, however, larger inter class distances were presented by the two wildtype samples (F. Chiloensis and F. Virginiana). Camarosa direct and Camarosa in vitro displayed a small overlapping region between them. On the other hand, Seascape variety presented the smallest rejection percentage among all varieties (more similarities with the rest of the samples). Therefore, it can be concluded that the application of NIRS technique allowed the authentication of all strawberry varieties and geographical origin as well. It was also possible to form subclasses of the same materials. The results presented here demonstrate that NIRS is a very powerful and promising analytical tool since all materials were authenticated and classified based on their variety, origin, and treatment. This is of a tremendous relevance since the variety and origin of a plant material can be established even before it gives its typical fruit or flower.

  • To evaluate the antibiotic resistance of Enterococcus from salad and sprout, Enterococcus were isolated and identified from 47 salad samples and 37 sprout samples, and then their antibiotic resistances were analyzed. Ninety five Enterococcus, 41 strains from salad and 54 strains from sprout, were ultimately isolated. The frequent Enterococcus in salad and sprout were E. gallinarum, E. faecalis, E. faecium, E. hirae, and E. avium. Minimum inhibitory concentrations of the isolates for vancomycin were below $4{\mu}g/mL$, which were not high levels of resistance. All Enterococcus proved to be resistant to streptomycin and chloramphenicol. Twenty two percentage of the isolates were resistant to penicillin, however, almost the isolates were sensitive to tetracycline. Eighteen percentage of the isolates were resistant to erythromycin. All E. faecium and E. faecalis were found to be ampicillin-resistant, and seven E. faecalis and five E. faecium were resistant to rifampicin. Overall antibiotic resistances of Enterococcus isolates were relatively low and low resistance to vancomycin was similar to those evidenced by Enterococcus isolated from the other foods. Therefore, there may be no special risk from the antibiotics resistances of Enterococcus and especially vancomycin-resistant Enterococcus from the fresh-cut salads and the sprouts.
