The purpose of this study was to investigate conception of children's hospitalization stress and to make clear concepts, and to use Walker & Avant's concept analysis method. Children's hospitalization stress attributes were derived from physiological changes, individual-environmental interactions, cognitive and psychosocial developmental stage responses, and intrinsic and outward changes due to coping styles. The prerequisites for hospitalization stress of children were disease severity, biological factors, and support system, and the results were hospitalization adaptation, disease and health recovery, improvement of child development, and acquisition of coping skills. In order to solve the prerequisites for Hospitalization stress of children, it is necessary to be aware of the disease and to establish a support system of parent-family. Afterwards, we suggest more qualitative research on the hospitalization stress of children, the development of tools that reflect the characteristics of the hospitalization stress of children, and the development of programs to solve the Hospitalization stress.
Childhood acute lymphoblastic leukemia (ALL) is one of the most common hematologic malignancies which accounts for one fourth of all childhood cancer cases. Exposure to environmental factors around the time of conception or pregnancy can increase the risk of ALL in the offspring. This study aimed to evaluate the influence of prenatal and postnatal exposure to high voltage power lines on the incidence of childhood ALL. It also examines the role of various factors such as environmental factors and alpha-amylase as a marker in the development of leukemia.This cross-sectional case control study was carried out on 22 cases and 100 controls who born and lived in low socioeconomic families in Tehran and were hospitalized for therapeutic purposes in different hospitals ofrom 2013-2014. With regard to the underlying risk factors; familial history and parental factors were detected as risk factors of ALL but in this age, socioeonomic and zonal matched case control study, prenatal and childhood exposure to high voltage power lines was considered as the most important environmental risk factor (p=0.006, OR=3.651, CI 95% 1.692-7.878). As the population study was from low socioeconomic state, use of mobiles, computers and microwaves was negligible. Moreover prenatal and postnatal exposure to all indoor electrically charged objects were not detected as significant environmental factors in the present study. This work defined the risk of environmental especially continuous pre and postnatal exposure to high voltage power lines and living in pollutant regions through the parents or children as well as the previously described risk factors of ALL for the first time in low socioeconomic status Iranian population.
This study investigates the diversity of news topic and source of the New York Times, Chicago Tribune, and the Los Angeles Times in the second half of the twentieth century. In probing the conventional traits of the contemporary press, the researcher traced the changing patterns and trends of news values in terms of news-gathering routine in order to evaluate the journalistic role conception in terms of social responsibility theory. Findings indicated that the American press as a neutral transmitter has been consistently violated by source and topic bias without any significant changes during the last five decades. The data, however, revealed the evident shift of the contemporary press from the heavy reliance of official source to the business/economic source. In addition, news topics such as business, health, and education have replaced the conventional popular topics such as crime and accidents. By contrast, it was revealed that the unconventional topics such as poverty, labor and minority still fail to receive the large attention from the target papers.
Objectives: The purpose of the study was to investigate the perception of clinical trials of dental hygienist. Methods: A self-reported questionnaire was filled out by 126 dental hygienists in Seoul, Kyonggi and other area from October 1 to November 15, 2012. The instrument of the study was adapted from Jung and reconstructed. The questionnaire consisted of general characteristics of the subjects(9 questions) and recognition for clinical trials(10 questions). Recognition for clinical trials instrument included recognition for clinical trial conception(2 questions), objective recognition(5 questions), and subjective recognition for clinical trial(3 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.936 in the study. Data were analyzed by SPSS 20.0 program and set at p<0.05. Independent t-test, chi-square test, one way ANOVA, and post-hoc Duncan test were done. Results: Those who had higher ages and higher education tended to have longer clinical careers(p<0.05). There was a significant difference in clinical trials between the level of education, clinical dental hygienists and professors. The differences in problem perception for activation of clinical trial according to workplace appeared to lack of publicity and inadequacy of facilities(p<0.05). Conclusions: To improve the perception of the clinical trials in dental hygienists, it is necessary to prepare the human resources programs, the additional curricula, continuing education courses and active publicity.
Object : From the ancient times, the importance of childbirth has been well recognized by Korean Traditional Medicine. Numeral methods have been developed to ease the labor process and keep the mother and child healthy from conception to labor. Bulsusan(佛手散) is one of the main remedies to healthy labor in KTM, both widely known and applied as well. Method : This paper examines the labor theory and practice of KTM focused on Bulsusan which is composed of Angelica gigas Nakai(當歸) and Cnidium officinale MAKINO(川芎). Result : 1. From the ancient times until the Q$\bar{i}$ng period, much attention was placed to the handling of the placenta, as it was conceived as bearing much relation to the health of the mother and her fate, and thus included in the labor process. 2. There was a recognition of the 'birth pulse[離經脈]', an intense change in the pulse that presents itself prior to somatic signs of labor. 3. There were numerous prescriptions that were administered beforehand to ease the process. They are mostly constituted with medicinals that nurture Gi(氣) and stimulate its flow, which in turn makes the fetus firm and reduces the volume, easing the labor process. 4. The medical practice of labor-induction was called 'Choesaeng(催生)'. The prescriptions which functioned as such were mostly constituted with blood medicinals such as Angelica gigas Nakai and Cnidium officinale MAKINO, those which nurture both Gi(氣) and blood, and medicinals that physically lubricate the labor pathway such as honey, oil and Talcum(滑石). Conclusion : Bulsusan can be used in most problems concerning pregnancy and labor, and cases of emergency blood loss due to injury. The term 'bulsu(佛手)' infers to the medical ability of the great doctor who takes care of major blood-loss situations resulting from discharge of dead fetus, cesarean delivery, etc. The prescription name takes after this meaning, as it deals with similar conditions in its effect.

This study was carried out to investigate the reproduction efficiency and disease of Holstein heifer grazed on mixed pasture desighed with association of tall fescue and white clover cultivar (3 treatments = TI : Tall fescue Fawn + White clover Regal + Orchardgrass + Perennial ryegrass, T2 : Tall fescue Roa + Ladino clover Regal + Orchardgrass + Perennial ryegrass, T3 : Tall fescue Roa + White clover Tahora + Orchardgrass + Perennial ryegrass) on reproduction efficiency and disease in Holstein heifers, ftom April 1994 to November 1996. The results are as follows: 1. Erythrocyte counts, hemoglobin and packed cell volume of hematological values were $8.12\times10^6/{\mu}\ell, 9.9g/m\ell and 30.6m\ell/100m\ell$ respectively. While those were decreased to $4.84~5.93 \times10^6/{\mu}\ell, 7.0~7.8g/100m\ell and 22.8~28.3m\ell/100m\ell$, on pastuage (May-August), WBC counts was increased from $14.4\times10^3/{\mu}\ell to 14.0~18.3 \times 10^{3/\mu\ell}$ on pasturage. No significant differences were detected among the treatments on pastures. 2. Parasitemia levels increased to $14.0\pm8.2$(parasite/1,000rbc) at 1 month after pasturage. 3. At the occurrence of tirst estrus and conception, the average age of the Holstein heifers was $14.3\pm1.9$ and $17.4\pm1.5$ months, respectively, and the average interval of estrus cycle was $20.6\pm1.0$ days. Howerer, there was no significant difference on reproductive efficiency among 3 treatments. 4. The outbreak of diseases were tick bane disease, pink eye, pneumonia, mastitis, gastroentitis, waterpoisoning ringworm papillon and atosis during pasturage period(may-october). These diseases were showed no significant difference among 3 treatments. 5. In conclusion, there are no significant difference on the reproductive effeciency and disease outbreak among three treatments.
Korean culinary culture is traditionally studied through the analysis of foods ingested. However, this study attempts to dialectically reinterpret Korean culinary culture through its relationship to Korean literature. In our study we consider culinary culture prior to the development of scientific techniques and economic growth related to food as "dietary lifestyle of the innocent world" and time since then as "the dietary lifestyle of the experience world". The former represents a simple means of survival without food processing (the "slow food" world), while the latter represents the "fast food" or processed food culture as a modern concept. People living in the age of economic growth and overflowing individualism have lacked an organic life and an opportunity to commune with nature. As a result, they have returned to values of the past, seeking the "slow food" culture to benefit their individual health. A series of return processes, however, were transformed into "the dietary life style of the higher innocence," called "a well-being dietary life style" involving a new healthy conception passing through the dietary life style of the experience world. Therefore, the purpose of this study is to investigate the dietary lifestyles of the "innocent" world and the "experience" world based on dialectic concepts. Individual concepts of "thesis" and "antithesis" are applied, as well as the developmental concept of "synthesis" for the way both symbolic worlds changed to "the dietary lifestyle of the higher innocence" and formed complementary relationships to each other.
The objective of this study was to investigate the interrelationship of weight and hormonal changes through the administration of vitamin A to first time pregnant heifers. A total of 28 Korean heifers was used for this study. The heifers were divided into two groups - with vitamin A (n=14) and without vitamin A (control) (n=14) in the feed. Body weight increased in vitamin A treated heifers starting 9 months until 15 months. After pregnancy, vitamin A treated heifers were found to maintain higher body weights than the control group. Pre-pregnancy and post pregnancy progesterone levels were not different between the two groups. Serum estradiol levels of heifers at different growth stages showed relatively higher E2 levels than the control. Also, the control during pregnancy may show higher serum E2 levels than the vitamin A treated heifers. The growth phase serum estradiol levels in heifers may be relatively higher than the control. During pregnancy it showed a similar trend. Serum levels of vitamin A treated heifers did not differ from pregnant heifers at 5 months of age. However, after 5 months from conception until 8 months of treatment it showed a high level. Serum cholesterol in pregnant cows was higher in the control group than the treatment from beginning until the end of pregnancy. This is considered to be related to fetus development during pregnancy, as well as the mother's health.

In Korea, chemical fertilizers and agricultural chemicals have had a significant impact on food production and these are today thought to be an indispensable part of modern agriculture. On the other hand, socioeconomical and IMF and WTO status in Korea are constant reminders of the vulnerability of our fossil fuel dependent agriculture. A new crop production system to improve economic, environmental and production efficiency must be exploited. Our particular concern has been given to an integrated cropping system involving recycling of crop residues, soil and N management, biological N fixation and multipurpose legumes. As a new integrated crop production system, a no-till direct-sown rice-vetch relaying cropping system has been proposed in this paper. The formulation of this system is based on the conception that N fertilizers being neither limitlessly available nor affordable, the current high-input crop production systems have produced troubled results severe labour shortage ill rural areas, balance of payment, environmental degradation and reduction of human health far exceed economic concerns. A natural and logical consequence is that long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. Based on the information obtained throughout a series of experiments last years we have proved that the no-till direct-sown rice-vetch relaying cropping system dictates biological alternative which can augment, and in some cases replace, N fertilizers. Comprehensive discussions were made for the proposed system and it concluded that the system can offer an economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources, and consequently improving the farmers as well as the national returns.

Purpose: We aimed to determine the differences in the levels of serum thyroid hormone (free T4 [FT4]) and thyroid stimulating hormone [TSH]) as biomarkers for hepatitis B virus (HBV) infection status, with respect to age and sex. Methods: We retrospectively analyzed serum samples from 200 patients who underwent HBV testing from August 2022 to September 2022. Serum samples were collected from patients suspected of having HBV infection who visited this hospital. Thyroid hormone levels were measured, and patients were grouped according to age and sex. Results: Differences in TSH and FT4 levels in the serum of patients in the HBV-positive and -negative groups were not significant. Among the HBV-positive patients in the younger age group (<60 years), TSH and FT4 levels were 1.78 ± 0.09 µIU/mL (normal: 0.4-5.0 µIU/mL) and 1.24 ± 0.02 ng/mL (normal: 0.8-1.9 ng/mL), respectively, whereas among the HBV-positive patients in the older age group (≥60 years), TSH and FT4 levels were 2.22 ± 0.17 µIU/mL and 1.24 ± 0.07 ng/mL, respectively. Conclusions: The presence of HBV did not markedly affect serum thyroid hormone levels. Our findings shed light on the conflicting evidence on the association between thyroid hormone levels and HBV infection. We, Hyeokjun Yun and Bo Kyeung Jung are co-first authors which made substantial contribution equally to the conception and designed of this work. Jae Kyung Kim, In soo Rheem and Kap No Lee made significant contributions to the acquisition and analysis of the data.
