Purpose: The study was designed to verify effects of aromatherapy on depression, anxiety and the autonomic nervous system in breast cancer patients who are undergoing adjuvant radiotherapy. Methods: Data were collected from November 2006 through March 2007 at the C university hospital in Seoul. The study included 33 patients and they were assigned to three groups. Group I had aroma oil inhalation for 2 minutes per time, three times a day for six weeks whereas Group II and a control group inhaled aroma oil for 2 minutes per time, once a day for six weeks. For Groups I and II, a mixture of lemon, lavender, rosewood and rose essential oils were used while control group inhaled tea tree oil. Results: Depression was significantly decreased in patients in the experimental groups only. In Groups I and II patients, anxiety level was lower than that in control patients. Patients in Groups I and II also showed stronger physical resistance to stress than control group patients. Conclusion: Aromatherapy should be considered as a method that can significantly decrease depression in breast cancer patients who are undergoing adjuvant radiotherapy.

Nutritional compositions of the raw materials, such as well-milled rice, milled upland glutinous rice, milled barley, glutinous millet, SoRiTae, red beans and mung beans were analysed, and cooking characteristics and sensory attributes of mixed cereals were measured. Crude protein and crude fat in SoRiTae were 31.6% and 16.16%, respectively, and the highest among the raw materials. Crude ash was 3~11 times higher and crude fiber was 5~7 times higher in legumes than in grains. Iron content in SoRiTae was the highest as 7.8 mg/100 g, and calcium content was the highest as 71.0 mg/100 g in SoRiTae and mung beans. Phosphorus content was higher in glutinous millet and mung beans, and potassium content was greatly higher in legumes than in grains and the highest as 934 mg/100 g in red beans. Vitamin B$_1$ and B$_2$ contents were higher in legumes than in grains, and niacin content was the highest as 5.51 mg/100 g in mung beans and was 3.77 mg/100 g in glutinous millet. Water uptake of the raw materials increased greatly after 5 min of soaking in water and then stayed at the almost same level. Water uptake was the highest in SoRiTae and decreased in the order of milled barley, milled upland glutinous rice, glutinous millet and well-milled rice. Hardness was the lowest as 142.8 g/cm$^2$ in cooked SoRiTae, and the highest as 206.3 g/cm$^2$ in cooked milled barley compared with 169.4 g/cm$^2$ in cooked well-milled rice. Cooking time increased and hardness of cooked mixed cereals decreased with the increase of water added. Moisture content decreased, while crude protein, crude ash and crude fiber increased as the increase of mixing ratio of SoRiTae and red beans in mixed cereals. Lightness decreased, while red and blue color increased, and hardness increased with the increase of mixing ratio of SoRiTae and red beans. Sensory evaluation showed greater preference in terms of color, roasted nutty, sweet taste and overall acceptance in the cooked mixed cereals with 8 and 10% of SoRiTae and red beans.
Objective: Birth sex ratio (BSR) with human IVF-ET program is an interesting subject of social and scientific issue but very little information is available in Korea. This study was performed to assess the BSR with IVF-ET and to suggest the effective factors on the BSR. Methods: The national data from 1991~2008 were obtained from governmental Statistics Korea and the delivery data of human IVF-ET program on 2007 and 2008 were provided from the Ministry for Health, Welfare and Family Affairs. The BSR were statistically analyzed according to methods of IVF and to transferred embryos from fresh or frozen-thawed cycles. Results: The BSRs of Korean populations were over 1.10 up to 2002, and then it declined and maintained to 1.06 as balance BSR on 2007 and 2008. In human IVF-ET program, the BSRs were 1.07 on 2007 and 1.06 on 2008, respectively. Conventional IVF on 2008 showed the highest BSR as 1.10, and ICSI the lowest on 2008 as 1.01. There was no significant difference of BSRs related to the methods of in vitro fertilization and the feature of transferred embryos. Conclusion: The BSR of Korea showed 1.06~1.07 as normal and balanced state on 2007 and 2008 both general populations and human IVF-ET program. To the best of our knowledge, this is the first study to evaluate the BSR of human IVF-ET in Korea. There is a need to expand the further studies for national statistics and influencing factors on the BSR with IVF-ET.
The foreign bodies in the food and air passages are frequently observed in the field of otolaryngology, and the foreign bodies in the air passages have much significance in clinical practice because they may cause sudden death. A statistical study was done on 95 cases of foreign bodies in the food and air passages who had visited department of otolaryngology, Chung-Ang university from June, 1968 to April, 1978. The results were as follows; 1. The total cases of foreign bodies in the food and air passages was 95; 89 cases (93.7%) were in the food passage and the remaining (6.3%) were in the air passage. The ratio between the food passage and air passage was about 14. 8 to 1.0. 2. In distribution by sex, 64 cases (67.4%) were in male patients and the remaining 31 cases (32.6%) were in female patients. The ratio between male and female was 2.1 to 1.0. 3. The kinds of foreign bodies in the food in the order of their frequency, were coin, gogame stone and pebble. In the air passages, the peanut and bean were most frequently found. 4. In distribution by age, 64 cases (67.4%) of all foreign bodies were found in children under 5 year old, and coin was the most common kind of foreign body. Except for meat, almost all of foreign bodies were found in children under 10 year old. 5. There was chronologically no significant tendency in incidence; the incidence, however, had decreased during recent 2 years. 6. In the location of foreign bodies in the food passage, 70 cases (78.7%) were found at the first esophageal narrowing. Meat was more frequently found at second esophageal narrowing associated with cicatrical stenosis. Almost all of foreign bodies in the air passage was found in bronchi; 3 cases were in the right side of bronchi, and 2 cases were in the left side of bronchi and 1 case was in glottic region. 7. In duration of lodgement, 50 cases (52.6%) visited our hospital within 24 hours, and 3 cases after 30 days. 8. Under topical anesthesia, 83 cases (93.3%) of the foreign bodies in the food passage were removed by esophagoscopy, by 6 cases (6.7%) failed to be removed. All of the foreign bodies of the air passages (6 cases) were removed by bronchoscopy. Among them, 5 cases under 5 years old were removed by inferior bronchoscopy through tracheostomy site.
The current paper presents a system dynamics model which can generate the land use anq transportation system performance simultaneously is proposed. The model system consists of 7 submodels (population, migration of population, household, job growth-employment-land availability, housing development, travel demand, and traffic congestion level), and each of them is designed based on the causality functions and feedback loop structure between a large number of physical, socio-economic, and policy variables. The important advantages of the system dynamics model are as follows. First, the model can address the complex interactions between land use and transportation system performance dynamically. Therefore, it can be an effective tool for evaluating the time-by-time effect of a policy over time horizons. Secondly, the system dynamics model is not relied on the assumption of equilibrium state of urban systems as in conventional models since it determines the state of model components directly through dynamic system simulation. Thirdly, the system dynamics model is very flexible in reflecting new features, such as a policy, a new phenomenon which has not existed in the past, a special event, or a useful concept from other methodology, since it consists of a lots of separated equations. In Chapter I, II, and III, overall approach and structure of the model system are discussed with causal-loop diagrams and major equations. In Chapter V _, the performance of the developed model is applied to the analysis of the impact of highway capacity expansion on land use for the area of Montgomery County, MD. The year-by-year impacts of highway capacity expansion on congestion level and land use are analyzed with some possible scenarios for the highway capacity expansion. This is a first comprehensive attempt to use dynamic system simulation modeling in simultaneous treatment of land use and transportation system interactions. The model structure is not very elaborate mainly due to the problem of the availability of behavioral data, but the model performance results indicate that the proposed approach can be a promising one in dealing comprehensively with complicated urban land use/transportation system.

Oceanic current maps in the secondary school science and earth science textbooks have played an important role in piquing students's inquisitiveness and interests in the ocean. Such maps can provide students with important opportunities to learn about oceanic currents relevant to abrupt climate change and global energy balance issues. Nevertheless, serious and diverse errors in these secondary school oceanic current maps have been discovered upon comparison with up-to-date scientific knowledge concerning oceanic currents. This study presents the fundamental methods and strategies for constructing such maps error-free, through the unification of the diverse current maps currently in the textbooks. In order to do so, we analyzed the maps found in 27 different textbooks and compared them with other up-to-date maps found in scientific journals, and developed a mapping technique for extracting digitalized quantitative information on warm and cold currents in the East Sea. We devised analysis items for the current visualization in relation to the branching features of the Tsushima Warm Current (TWC) in the Korea Strait. These analysis items include: its nearshore and offshore branches, the northern limit and distance from the coast of the East Korea Warm Current, outflow features of the TWC near the Tsugaru and Soya Straits and their returning currents, and flow patterns of the Liman Cold Current and the North Korea Cold Current. The first draft of the current map was constructed based upon the scientific knowledge and input of oceanographers based on oceanic in-situ measurements, and was corrected with the help of a questionnaire survey to the members of an oceanographic society. In addition, diverse comments have been collected from a special session of the 2013 spring meeting of the Korean Oceanographic Society to assist in the construction of an accurate current map of the East Sea which has been corrected repeatedly through in-depth discussions with oceanographers. Finally, we have obtained constructive comments and evaluations of the interim version of the current map from several well-known ocean current experts and incorporated their input to complete the map's final version. To avoid errors in the production of oceanic current maps in future textbooks, we provide the geolocation information (latitude and longitude) of the currents by digitalizing the map. This study is expected to be the first step towards the completion of an oceanographic current map suitable for secondary school textbooks, and to encourage oceanographers to take more interest in oceanic education.
This article discusses the contributions of the leader Oswald Veblen, who was the president of AMS during 1923-1924. In 2006, Korea ranked 12th in SCIE publications in mathematics, more than doubling its publications in less than 10 years, a successful model for a country with relatively short history of modern mathematical research. Now there are 192 four-year universities in Korea. Some 42 of these universities have Ph.D. granting graduate programs in mathematics and/or mathematical education in Korea. Rapid growth is observed over a broad spectrum including a phenomenal performance surge in International Mathematical Olympiad. Western mathematics was first introduced in Korea in the 17th century, but real significant mathematical contributions by Korean mathematicians in modern mathematics were not much known yet to the world. Surprisingly there is no Korean mathematician who could be found in MaC Tutor History Birthplace Map. We are at the time, to have a clear vision and leadership for the 21st century. Even with the above achievement, Korean mathematical community has had obstacles in funding. Many people thinks that mathematical research can be done without funding rather unlike other science subjects, even though they agree fundamental mathematical research is very important. We found that the experience of early American mathematical community can help us to give a vision and role model for Korean mathematical community. When we read the AMS Notice article 'The Vision, Insight, and Influence of Oswald Veblen' by Steve Batterson, it answers many of our questions on the development of American mathematics in early 20th century. We would like to share the story and analyze its meaning for the development of Korean Mathematics of 21st century.
The purpose of this study was to evaluate diet-related Quality of Life (QOL) and to analyze the relationship among diet-related QOL, dietary regimen practice, health-related QOL, and gastrointestinal symptoms in hemodialysis patients. Subjects were recruited from an artificial kidney center in Seoul. The self-report questionnaire consisted of socio-demographic characteristics, diet-related QOL, compliance with dietary regimen practice, health-related QOL, and gastrointestinal symptoms was distributed. Diet-related QOL includes a 'Quality of Life and Related to Dietary Change Questionnaire', 'Satisfaction Survey', and 'Dietary Impact Survey'. According to their responses, participants had experienced the greatest difficulty with 'Dietary Impact'. In particular, the mean score for general health was low. Association of dietary regimen practice showed a positive association with 'Cost' and 'Self-care' score. In addition, diet-related QOL showed positive correlation with health-related QOL, particularly in 'taste'. Scores for 'Taste', 'Convenience', and 'Dietary Impact' were lower for subjects with constipation compared to those of subjects without constipation. Scores for 'Taste' and 'Dietary Impact' were lower in subjects with irritable bowel syndrome compared to those of subjects without the syndrome (p < 0.05). Diet-related QOL showed a positive association with health-related QOL (p < 0.05), whereas it showed a negative association with constipation (p < 0.01). In conclusion, hemodialysis patients in Korea suffer from burden of dietary regimen practice and most scores for diet-related QOL and health-related QOL from patients with gastrointestinal symptoms were low. Therefore, appropriate nutrition education considering gastrointestinal symptoms is necessary for improvement of patients' QOL during dietary regimen practice.

Objectives : The aim of this study is to evaluate difference of somatic symptoms of anxiety disorder and major depressive disorder and domainal association with suicidal idealization, plan, and attempts. Methods : A total of 359 adults diagnosed with major depressive disorder and anxiety disorder of last one year participated. Participants interviewed with certain sections of Korean version of Composite International Diagnostic interview of CIDI. Sections of interests includes questionnaires regarding somatic symptoms and suicidal idea, plan and attempts of last one year. Results : Chest pain shows more prevalence in major depressive disorder. Symptoms of Headache and loose stool are more prevalent in anxiety disorder. Difficulty in equilibrium and fainting spells are more common somatic complaints of co-diagnosis states of anxiety disorder and major depressive disorder. Comparing 3 domains of pain symptoms, gastrointestinal symptoms and pseudo-neurological symptoms, pain symptom domains, gastrointestinal symptoms domain shows significant statistic difference between diagnosis. Average somatic symptom numbers of each symptom domains increase through suicidal idealization, plan and attempt, accordingly. Conclusions : Our finding shows some of somatic symptoms are more prevalent at certain diagnosis. Since increasing numbers of somatic complaints of each symptom domains goes with the suicidal idealization to suicidal attempts, proper psychiatric evaluation and consultations are crucial for patients with numerous somatic complaints in non-psychiatric clinical settings.

The concept of household labor is composed of housework and family care, and it provides a framework for understanding daily life from the perspective of work-life balance. The purpose of this study was to investigate the household labor time of Korean adults by gender and generation over the last 20 years. Data was taken from the five Statistics Korea Life Time Surveys from 1999 (t1) to 2019 (t5) (n=69,196). The major results are as follows: first, gender and generation were found to have a significant relationship with household labor time over the study period. Household labor time for females was 3.8 times that of males in 1999, but females' household labor time decreased over the next 20 years while males' increased, including both housework and family care. The female participation rate in household work also remained steady, while that for males increased. Second, in the younger and middle generations, a similar gender and generational pattern was seen. Third, in the older generation, household time and participation rates for both females and males increased. The family welfare policy and theoretical implications of these results are discussed.
