The abandoned island Naoshima was reborn with the will of Chairman Soichiro Fukudake and the efforts of Tadao Ando. Tadao Ando designed the Benesse House Museum, the Chichu Art Museum, and the Lee Ufan Museum, which are called the three major museums of Naoshima. The museum of Ando designed buildings that harmonize with architecture, nature, and human beings. Among them, Lee Ufan of Lee Ufan Museum is a painter who focused on relationality in particular. In this study, the Lee Ufan Museum was selected as an example. This research focuses on the analysis of their conceptual relationship with the Lee Ufan Museum and the spatial composition that it implemented in architecture. The research methods include literature review, drawing analysis and field trip. Lee"s work trends can be seen to be concentrated on the relationship such as ‘objects-objects’, ‘objects-spaces’, and ‘objects-human beings’. From the perspective of Lee Ufan"s conceptual relationships, the architecture of Tadao Ando can be understood as the relationship such as ‘architecture-exposed concrete(matter)’, ‘architecture-human(moving line)’, and ‘architecture-nature(place)’. Through this analysis, the Lee Ufan Museum is not merely a solo work of Tadao Ando, but a successful case in which two outstanding artists to keep in step together as a collaboration between Ando and Lee.

Tracheobronchopathia osteochondroplastica (TPO) is a rare benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. Although some disorders were reported combined with TPO, these seemed to be considered casual. We report a case of TPO that combined with adenocarcinoma of lung. She was 50-year-old non smoking woman presented with chronic cough with right chest pain. Lung mass on right lower lobe was found on chest x-ray, so lung cancer was suspected. Multiple scattered whitish small elevations from trachea to bronchial trees were found on bronchoscopic exam. We mistook these lesions for metastases from lung cancer and biopsies of these lesions were done. Transbronchial biopsy for right lower lobe mass lesion was also done. But biopsies from trachea and bronchus revealed TPO rather than lung cancer. Transbronchial lung biopsy of right lower lobe mass was diagnosed adenocarcinoma of lung. So TPO combined with adenocarcinoma of lung was diagnosed.

In order to obtain an useful information for health management and biological monitoring of lead exposed workers, Authors tried to investigate air lead level and the lead exposed level of workers in lead industry according to occupational category. The subjects in our study were 2074 workers in 7 lead-using industries, and study subjects were divided into 4 occupational categories such as storage battery industry (type 1), primary smelting industry (type 2), secondary smelting industry (type 3) and litharge making industry (type 4). Blood zincprotoporphyrin concentration (ZPP), blood lead concentration (PbB) and urinary δ -aminolevulinic acid (ALAU), hemoglobin (Hb), hematocrit (Hct) were selected as the indices of lead exposure. Personal variables such as age, work duration were also collected. The results were as follows. 1. The geometric mean air lead in 9 lead-using industry was 0.1133±4.3120 ㎎/㎥, and that in type 1, 2, 3 and 4 was 0.1038±3.4952 ㎎/㎥, 0.0429±3.4329 ㎎/㎥, 0.1877±2.5123 ㎎/㎥ and 0.9961±5.2910 ㎎/㎥, respectively. 2. The mean ZPP in 9 lead-using industry was 53.1±28.0 ㎍/㎗, and that in type 1, 2, 3 and 4 was 52.0±24.8 ㎍/㎗, 48.0±16.4 ㎍/㎗, 109.8±85.6 ㎍/㎗ and 74.3±37.8 ㎍/㎗, respectively. There was significant difference in ZPP according to occupational category (P<0.01). The percents of lead workers whose ZPP were above 100 ㎍/㎗ in type 1, 2, 3 and 4 were 4.0%, 1.7%, 34.3% and 21.6%, respectively. 3. The mean PbB in lead-using industry was 26.0±11.2 ㎍/㎗, and that in type 1, 2, 3 and 4 was 25.3±11.1 ㎍/㎗, 26.7±8.8 ㎍/㎗, 50.3±15.2 ㎍/㎗ and 36.4±11.0 ㎍/㎗, respectively. There was significant difference in PbB according to occupational category (P<0.01). The percents of lead workers whose PbB were above 40 ㎍/㎗ in type 1, 2, 3 and 4 were 10.4%, 7.7% 71.9% and 43.2%, respectively. 4. While the correlation of Hb corrected PbB with ZPP was higher than non corrected PbB, the correlation of log-transformed ZPP with PbB was higher than non corrected ZPP. 5. Simple linear regressions of PbB and corrected PbB as independent variable with ZPP, log-transformed ZPP and ALAU as dependent variable were statistically significant (P0.01). Coefficient of determination of corrected PbB with other variables was higher than non corrected PbB. As the result of this study, it was suggested that reconsideration of environmental and biological monitoring program was highly recommended for secondary smelting and litharge making industry.

To evaluate the blood pressure change of lead workers by lead exposure level, authors analyzed 1,009 lead workers. Study variables were systolic and diastolic blood pressure, smoking and drinking habit, age, work duration, blood lead concentration(PbB), ZPP, hemoglobin, BMI and cholesterol. The results were obtained as follow; 1. Means of systolic and diastolic blood pressure were 126.93mmHg and 74.08mmHg. Systolic pressures were significantly higher in males and drinkers than in females and non-drinkers. Blood pressure was increased as age and work duration were increased. 2. Means of PbB and ZPP were 26.79㎍/㎗, 61.38㎍/㎗ respectively. Male workers' PbB was higher than female workers', and ZPP was contrary. PbB and ZPP were increased as age and work duration were increased. Smokers' and drinkers' PbB were not different from nonsmokers' and nondrinkers' but ZPP were lower. 3. As PbB was increased, systolic pressure was increased, but diastolic pressure was not increased. 4. There were no significant increase in both systolic and diastolic pressure by increase of ZPP. 5. In pearson's correlation analysis, systolic pressure was correlate with BMI(R^(2)=0.2618), hemoglobin (R^(2)=0.1794), cholesterol(R^(2)=0.14334), PbB(R^(2)=0.12616) and alcohol consumption per week(R^(2)=0.10925). 6. In pearson's correlation analysis, diastolic pressure was correlate with BMI(r-square : 0.25037), age, hemoglobin, cholesterol and work duration, but not correlate with PbB. 7. Forward multiple regression analysis using systolic pressure as dependent variable revealed that BMI, PbB hemoglobin and cholesterol in order were significantly contributed to dependent variable. 8. Forward multiple regression analysis using diastolic pressure as dependent variable revealed that BMI, age, hemoglobin, smoking and cholesterol in order were significantly contributed to dependent variable.

In 1965 Lauren divided advanced gastric carcinoma into two main types-namely, "intestinal" and "diffuse" type carcinoma, which differ not only morphologically but also in their clinical and epidemiological characteristics. Moreover, a different histogenetic process has been postulated by many authors that intestinal type gastric carcinoma might arise from areas with intestinal metaplasia. Since Warren and Marshall reported the presence of Helicobacter pylori in the stomach in 1983, strong evidence has been obtained that there is a close relationship between Helicobacter pylori and chronic gastritis, atrophic gastritis, intestinal metaplasia, and intestinal type gastric carcinoma. To study the relationship between intestinal metaplasia and Helicobacter pylori infection, we performed gastroscopic biopsies and CLO tests taken from patients with epigastric pain. Only 87 patients with macroscopically suspected antral gastritis were included. The prevalence of intestinal metaplasia in gastric antral biopsies increased from 33.3% in the age group<30 years to 63.6% in the age group 60 years. When all patients were divided into two age groups-namely, (i)<50 years(n=41) and (ii)≥ 50 years(n-=46), intestinal metaplasia was found significantly more often in patients ≥ 50 years. ((i) 39.2%, (ii) 54.3%, p<0.0001). The prevalence of Helicobacter pylori in gastric antral biopsies decreased from 66.7% in the age group<30 years to 62.5%, in the age group in the age group 50 to 59 years. When all patients were divided into the same two age groups-namely(i)<50 years and (ii)≥50 years, the prevalence of Helicobacter pylori did not differ between two groups in a statistically significant way. The mean age of intestinal metaplasia positive patients who were also Helicobacter pylori positive was 48±11.0(mean±S.D.)years, whereas the mean age of intestinal metaplasia positive patients who were Helicobacter pylori negative was 52±9.7(mean±S.D.)years. In conclusion. although our data do not prove a causal relationship between Helicobacter pylori infection and the histogenesis of intestinal metaplasia, we suggest that Helicobacter pylori plays an important role in the development of intestinal metaplasia in the gastric mucosa. Whether Helicobacter pylori has to be present at all times during this process or is only necessary as a 'trigger', needs further research.

Alterations in DNA methylation patterns in regenerated Chinese cabbage (Brassica rapa ssp. pekinensis) plants derived from tissue culture

Hyun‑Min Lee,Jee‑Soo Park1,Yun‑Hee Shin,박영두 한국원예학회 2021 Horticulture, Environment, and Biotechnology Vol.62 No.4

Plant tissue culture is an essential tool in biotechnology. However, tissue-cultured plants often exhibit variations that are either genetic or epigenetic in origin, termed somaclonal variations. Among these variations, DNA methylation is an important heritable epigenetic modification that plays a role in a wide variety of biological processes, including gene expression. In this study, we performed bisulfite sequencing of regenerated Chinese cabbage (Brassica rapa ssp. pekinensis) lines to identify DNA alterations induced by tissue culture. Sequencing data from each regenerated line were compared with reference genome sequences, and common differentially methylated regions (DMRs) were detected in the regenerants. To determine changes in expression levels of DMR-containing genes, we performed quantitative reverse transcription-polymerase chain reaction (qRT-PCR) of the target genes and PCR amplification with bisulfite-converted DNA. We identified DMRs between a non-regenerant line and regenerant lines and selected 10 DMR-associated genes that presented annotation information in Arabidopsis or Brassica rapa. Their expression levels were verified by qRT-PCR to determine the relation between methylation state and gene expression. We observed that genes positioned in DMRs significantly correlated with differential gene expression. We also observed similar methylation patterns in the selected DMRs by PCR-based methylation analysis. The results of this study are a valuable resource for the epigenetic analysis of regenerated lines, especially for Chinese cabbage.

납 폭로 근로자에서 δ-aminolevulinic acid dehydratase 유전형질이 zinc protoporphyrin 및 δ-aminolevulinic acid에 미치는 영향

이병국,황규윤,장봉기,김용배,리갑수,안현철,김화성,이성수,안규동,박종범 순천향대학교 산업의학연구소 1999 순천향산업의학 Vol.5 No.1

The inhibition of δ-aminolevulinic acid dehydratase (ALAD) in the heme synthetic pathway results in increased protophoryphyrin (ZPP) and δ-aminolevulinic acid (ALA) and is responsible for some of toxicological effects of lead. This enzyme is coded by the ALAD gene containing 2 co-dominant alleles. The polymorphisms of ALAD gene may be related to differential effects of lead on ZPP and ALA, ALAD genotype was measured in 975 Korean male lead workers, of whom 897 were homozygous for ALAD1 (ALAD 1-1 genotype) and 96 were heterozygous for ALAD2 (ALAD 1-2 genotype). Blood lead in subjects with ALAD1 was significantly higher than those with ALAD2 (p = 0.01). No difference between ALAD genotypes was found for age, exposure duration, ZPP, ALA, hemoglobin, hematocrit, body mass index, tobacco and alcohol use. After adjustment for possible confounders, ALA and ZPP became significantly elevated in ALAD1 subjects (p = 0.004 and 0.055, respectively). This result suggests that ALAD1 subjects may be more susceptible to the hematotoxicologic effects of lead than ALAD2 subjects.
