This study was designed to assess the iron nutritional status and anemia of middle school girls in Ulsan City, who were evaluated with a questionnaire, measurement of hematological indices. The average height and weight of respondents were 154.81$\pm$6.28cm and 48.51$\pm$8.80kg, respectively. Mean daily energy intake was 1815.72$\pm$328.04kcal and iron intake was 15.13$\pm$4.50mg. The average hemoglobin concentration of subjects was 11.98$\pm$0.78g/dl, and the average hematocrit level was 36.62$\pm$2.21%. Transferrin saturationTS (%) was 25.58$\pm$9.82%, and the ferritin level was 40.45$\pm$23.03ng/ml. Iron deficiency anemia among the subjects was estimated as 54.2% by using hemoglobin(<12g/이), 33.9% by hematocrit (<36%). The clinical symptoms relating anemia were measured with 4 Likert scale (1 : never, 4 : often), 'tired out easily (2.34$\pm$0.92)' was the highest, followed by 'feel dizzy always (2.26$\pm$0.85)', 'decreasing ability to concentrate (2.23$\pm$0.77)', 'get a cold easily (2.19$\pm$0.82)', 'have a headache (2.10$\pm$0.79)', 'poor memory (2.09$\pm$0.83)', 'no appetite (1.99$\pm$0.85)', As for the correlation between iron parameter and clinical symptoms related to anemia, the hematocrit rate was negatively correlated with 'get a cold easily', 'pale face', 'feeling blue', 'difficult digestion' (p<0.05). The level of iron was negatively correlated with 'tired out easily', 'get a cold easily' (p<0.05) and TS (%) were negatively correlated with 'tired out easily (p<0.05)', 'get a cold easily (p<0.01). Our study resulted that the prevalence of a iron deficiency of a middle school girl is very high, therefore the guidelines for iron supplementation and nutritional education to improve their iron status should be provided.

This study compared indoor air quality of homes in which elementary school children with and without (case and control) allergic rhinitis live in the Ulsan metropolitan region (UMR). A total of 58 homes (case and control: 29, respectively; children aged 7 to 12 years) was selected for indoor air quality measurements. The concentrations of all general indoor air pollutants, except $PM_{2.5}$, in the case group were much higher than those in the control group. In particular, the average concentrations of $O_3$ and $NO_2$ in the case group were statistically significantly (p<0.05) higher than those in the control group. Average concentrations of $CO_2$ in the case and control groups and $NO_2$ in the case group exceeded the standard level. Some components of aldehydes and ketones and VOCs indicated large difference of average concentrations between two groups, but there were no statistically significant differences.

The central of Ulsan was formed and has been developed in alluvial plains the Riverfront of Taehwa River and Dongcheon River Fortresses including Gyebyeonseong of the late Silla, Chisoseong of the Goryeo, Ulsan Gyeonsangjwabyeongyeongseong, Ulsaneupseong, Ulsanwaeseong and Yeompoyeongseong as well as Gugangseowon and Old Ulsanhyanggyo and other facilities well display such fact. In the southern areas of Taehwa River, Byeokpajeong of Samsan, Buddhist temples and pavilion architectures used to be located. In its upstream areas, Eonyangeupseong, Eonyanghyanggo, Banguseowon and Daegokcheon Petroglyph exist as well. As such, the Riverfront of Taehwa River are a central space where the civilization of Ulsan has grown and developed, and are regarded as a core scenic asset of Ulsan. However, the look and nature of Taehwa River changed significantly due to Ulsan irrigation project and the construction of modern bridges such as Ulsangyo and Ulsan railway bridge during the period of Japanese occupation. The old look of the area started to be ruined by water contaminations and developments of waterfront lands that resulted from the development of Ulsan Industrial Center in 1962. The water quality of Taehwa River has been improved as a result of allotting a huge budget and administrative powers before and after 1997, the year when Ulsan was elevated to a metropolitan city. However, the surrounding views around Taehwa River changed greatly due to various urban development projects including apartment complex constructions. This is because the development of the Riverfront started from a land utilization project, in which the construction of apartment complexes was included in the initial phase; as a result, the areas were changed to be private scenic assets for those apartments. Aware of such issue, this study aims to identify major scenic elements that were present in the period before such developments in the river's surrounding areas from literature and geography materials; and to reveal how various urban development projects that have been performed from the period of Japanese occupation have changed the scenic elements of Riverfront of Taehwa River. The purpose of this study is to identify qualitative and quantitative changes in scenic elements of the Riverfront of Taehwa River as well as the characteristics of the resulting changes in the surrounding scenery.

This study aims to investigate both general dietary behaviors and clinical symptoms of diet related effects among fifth grade students at an elementary school in Ulsan Metropolitan City, and to categorize those relationships in terms of their comparative differences. The findings of this study are as follows. 1. Out of 694 students polled, 53.7% were of boys and 46.2% were girls with average age of $11.9{\pm}0.3$, average height of $145.1{\pm}6.8cm$, and average weight of $39.7{\pm}9.7kg$. Obesity in boys (5.5%) exceeded girls (3.9%) whereas children categorized as underweight showed girls (14.6%) slightly exceeded boys (10.4%). 2. Dietary behaviors were largely the result of four factors - unbalanced diet, balanced diet, protein and fruits and healthy dietary habits. Of these factors, protein and fruits ($4.04{\pm}1.03$) ranked first, balanced diet ($3.38{\pm}1.04$) second, healthy dietary habits ($3.04{\pm}1.01$) third and unbalanced diet ($2.23{\pm}0.6$) ranked last. 3. When Dietary behaviors were classified with four low ranking factors, they were divided into four types such as convenience (22.4%), good diet (24.7%), busy contemporary modern man (24.3%) and healthy dietary habits (26%). 4. Clinical symptoms include colds ($2.27{\pm}1.15$) followed by headaches ($2.17{\pm}1.19$), stomachaches ($2.16{\pm}1.15$), dizziness ($2.02{\pm}1.15$), atopic allergy ($1.95{\pm}1.30$), prevalence for cold sores ($1.86{\pm}1.07$), allergy ($1.65{\pm}1.05$), and constipation ($1.54{\pm}0.87$). 5. According to the results, clinical symptoms were divided into two groups - unhealthy (40.1%) and healthy (59.9%). 6. By analyzing the relationship between dietary behavior types and clinical symptom types, the convenience factor included slightly more of the unhealthy group (56.3%), whereas the good diet (71.1%), busy contemporary modern person (55.8%) and healthy dietary habits (69.7%) included more of healthy group (p<.001). Since the majority of students belonging to the unhealthy group had convenience dietary behavior, education about desirable dietary activities is needed for these students. In addition, nutrition information and information on possible clinical symptoms caused by nutritional imbalance should be provided for students and their households.

Tree-ring width analysis has been used to assess the effects of air pollution on tree growth around industrial complexes. Our study was conducted to elucidate the effect of air pollutants on annual ring growth in black pines (Pinus thunbergii) of age 41$\sim$48 years around Ulsan Metropolitan City. The growth data were analyzed by multiple regression and the results are as follows: 1. The annual ring increment of black pines increased with tree age until age 40 years and then decreased gradually after age 40 years. 2. The increment of annual ring width of black pines was affected more by precipitation and evapotranspiration than air temperature. An annual ring decline appeared in the years 1968$\sim$1983, when annual ring indices below zero were observed. Decreased annual ring growth during this period may have been due to air pollution. 3. The heavy metal with the strongest effect on annual ring growth of black pines in the experimental stand was lead (Pb). The concentration of lead in the stand was estimated as over 6 ppm. 4. The technique of tree-ring width analysis may be useful for estimation of the extent of pollution in forest areas near industrial complexes.
