Interpreting Reproductive Health Right from International Human Rights Treaties: Application to Abortion Policies in Korea

Han,Ju Youn,Yoo,Doo Hyun,Lim,Jae Kwang 가톨릭생명윤리연구소 2012 인격주의 생명윤리 Vol.2 No.2

The recent trend in international politics seems to project that right to procure abortion is universally recognized under the 'right to reproductive health'. However, such contention is ungrounded from the perspective of international human rights law, since human rights documents remain silent about the issue of abortion. It agrees upon holistic universal principles to protect the dignity of life and personhood which includes both the unborn and women. The task of policy-making on specific issues is delegated to the legislation of respective nations, who must carefully analyse the socio-legal dimension to devise laws that are effective. This essay refutes the said claim that abortion is a universally recognized right, by scrutinizing the international treaties ratified by Korea. It suggests that the principles of the treaties should be best interpreted to in respect to the personhood of both women and the unborn. Then, it scrutinizes the issue of abortion in Korea, both from social and legal perspective. The essay concludes by claiming that Korea should maintain its criminal ban on abortion, while taking steps to meet the international standard of procuring 'Right to Reproductive Health' in the Korean context.

NPIs and Rhetorical Question in Korean

Cho, Sae Youn,Lee, Han Gyu 대한언어학회 2001 언어학 Vol.9 No.1

Cho, Sae-Yom and Lee, Han.-Gyu. 2001. NPIs and Rhetorical Question in Korean. The Linguistic Association f Korea Journal, 9(1), 145-166. This paper provides a syntactic end pragmatic account of the Negative Polarity Items (LAPIS) end Rhetorical Question (RQ) in Korean, which would be hard to explain under current syntactic views (Sohn, 1995). For a theory of NPIS to be adequate, it must answer the following questions'. (i) What is an appropriate constraint to NPIS to explain the difference in distributional behaviors between Declarative Sentences (DS) and RQ?, and (ii) Why does such a difference exist depending o constructions? To answer these questions, we propose that the distributional behavior can be dealt with by specifying lexical properties of NPIs still positing a construction type, and suggest that sentences with NPIs can be fully understood by discerning the pragmatic role of NPIs at issue.

The characteristic of the water quality and pollutant discharge was analyzed at the units watershed of the total amount management in Han-river basin, and after classified in a similar area by multivariate statistical analysis, the main trend such as the water quality trend and pollutant discharge characteristic were analyzed. As a result of this study, the density of the pollutant at the unit watershed is not necessarily identified as discharge density, and the primary management watershed and targeted substances were analyzed depending on the operating status of the environmental infrastructure in watershed and the main pollution factor and discharge path per pollutants. As a result of cluster analysis, watersheds were classified into four groups according to discharge characteristics. It will be used when selecting target area of primary management that is appropriate to the characteristics of each river and establishing efficient water quality improvement plans.

김연천,전옥경,양혜란,최영희,한선희,이강문,Kim, Youn-Choen,Chun, Ock-Kyoung,Yang, Hae-Ran,Choi, Young-Hee,Han, Sun-Hee,Lee, Kang-Moon 한국식품위생안전성학회 2000 한국식품위생안전성학회지 Vol.15 No.3

한강 고수부지 및 지천인 안양천, 탄천, 중랑천변의 경작지에서 채집된 36종 285건의 농작물에 대한 Pb, Cr, Cd, Fe, Zn, Mn, Cu. Hg의 농도를 측정하고 그 결과를 채집 시기, 채집 지역 및 작물별로 비교, 분석한 결과, 작물 중의 중금속 함량은 평균치를 기준으로 볼 때 Fe(34.592 ppm)>Mn(11.071 ppm)>Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm) 순으로 곡류 및 두류에서는 Zn의 함량이 Mn보다 높고, 채소류와 과실류에서는 Mn의 함량이 Zn보다 높은 양상을 나타냈다. 또한 각 지역에서 채취한 작물의 미량금속 함량의 경우 Fe은 0.004∼203.083 ppm, Cu은 0.017∼22.727 ppm. Mn은 0.000∼74.373 ppm. Zn은 0.080∼37.166 ppm으로 비교적 고농도로 존재하고 있는 반면 유해중금속류인 Pb은 0.000∼0.654 ppm, Cd은 0.000∼0.270 ppm, Cr은 0.000∼l.229 ppm, Hg은 0.000∼0.037 ppm으로 비교적 미량으로 존재함을 알수 있었다. 대상 농작물을 잎, 줄기, 뿌리, 열매로 분류하여 미량금속 함량을 분석한 결과, 분석 대상 금속의 농도가 잎>줄기>뿌리>열매의 순으로 나타났다. 무등의 뿌리 작물에 있어서 Pb은 잎(0.055 ppm))뿌리(0.035 ppm), Cr은 잎(0.118 ppm))뿌리(0.031 ppm), Cd은 잎(0.004 ppm)1뿌리(0.001 ppm), Hg은 잎(0.004 ppm))뿌리(0.001 ppm)으로 뿌리보다 잎에 많은 것으로 나타났는데 이러한 결과로 보아 뿌리는 금속 이온이 흡수되는 기관일 뿐 축적은 잎에 비해 상대적으로 적게 됨을 알 수 있었다. This study was conducted to determine the content of trace metals in crops cultivated in Han-riverside, Anyang stream, Tan stream, and Jungryang stream. Trace metals (Pb, Cr, Cd, Fe, Zn, Cu, Hg) were detected in 36 crops, 285 samples by Atomic Absorption Spectrophotometer and Mercury Analyzer. The average concentration of trace metals in crop samples was in the order of Fe (34.592 ppm)>Mn (11.071 ppm)$\geq$Zn(8.853 ppm)>Cu(1.795 ppm)>Cr(0.237 ppm)>Pb(0.100 ppm)>Cd(0.011 ppm)>Hg(0.003 ppm). In crop samples, the contents of Fe, Cu, Mn, and Zn, which ranges were 0.004-203.083 ppm, 0.017~22.727 ppm, 0.000~74.373 ppm, 0.080~37.166 ppm, respectively, were relatively higher than those of Pb, Cd, Cr, and Hg, which ranges were 0.000~0.654 ppm, 0.000~0.270 ppm, 0.000~l.229 ppm, 0.000~0.037 ppm, respectively. The concentration of trace metals in crop samples was in the order of leafy vegetables > stem vegetables > root vegetables > fruity vegetables. In the root vegetables, such as radish, the content of Pb was leaf(0.055 ppm)>root(0.035 ppm), that of Cr, leaf (0.118 ppm)>root(0.031 ppm), that of Cd, leaf(0.004 ppm)>root(0.001 ppm), that of Hg, leaf(0.004 ppm)>root(0.001 ppm). As the results, it could be thought that root is the organ which doesn't accumulate the heavy metal ions, but absorb them.

자일리톨 껌 저작에 의한 유치 우식증 예방효과 비교분석

한성근,최연희,손은영,송근배,김영진,남순현 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.2

자일리톨 껌 저작에 의해 어린이들의 유치우식증 예방효과를 평가하기 위하여 3개 어린이집에서 만 5~6세 어린이 123명을 최종 선정하였다. 자일리톨 껌을 씹는 군(42명), 솔비톨 껌을 씹는 군(42명) 그리고 아무런 조치도 취하지 않은 대조군(39명)으로 나누어 12개월 동안 하루 5회씩 껌을 저작하게 한 다음 구강검사와 우식활성 검사를 통해 유치우식증 예방효과를 비교 분석 하였다. 12개월 동안 대조군 어린이들에서는 dfs index가 5.19개면 증가하였고 솔비톨 군에서는 2.96개면이 증가한 반면 자일리톨 군에서 2.62개면이 증가하여 대조군에 비해 자일리톨 군은 47.1%가 감소하였고 솔비톨 군에서는 43.6%가 감소한 것으로 나타났다. Dentocult-SM strip 검사 및 site strip 검사 결과 모두에서 대조군에 비해 자일리톨 껌과 솔비톨 껌을 씹은 군의 아동들에서 우식활성도가 공히 감소되었다. 따라서 본 연구와 같은 집중적인 자일리톨 껌의 저작 사업은 대상자들과 부모들의 사업에 대한 호응도가 높았고, 사업 시행이 다른 국책 구강보건사업에 비해 용이하였으며 특히 유치우식증 예방적인 측면에서 효과적인 것으로 나타났다. The effect of xylitol and sorbitol chewing gums on dental caries levels among 5-year old kindergarteners was investigated. Three kindergartens the operations of which were partly subsidized by municipal government of Daegu city, Korea, were chosen as the study sites. The child base of the kindergartens were considered demographically and ethnically similar, representing middle-income families. The subjects were examined at their own kindergarten by the two dentists. Participation in the program was voluntary. Over 12 months, 123 participants chewed xylitol chewjng gums(X group; 42 subjects), sorbitol chewing gum@ group; 42 subjects), or did not receive chewing gum as a control group(C group: 39 subjects). Consumption of xylitol and sorbitol was 4.5 to 5.0 g/day/subject, consumed in five daily chewing episodes of 5 min. Oral examination, Dentocult-SM test and interproximal dental plaque collection were completed at baseline and 12 months later. The dmfs of group C increased 59.2%. but group S increased 33.4% and group X increased only 31.3% during 12 months study period. The caries prevention ratio was 47.1% at group X and 43.6% at group S. There also appeared the reduction of caries activity at group X(1.39), group S(1.50) than control group(1.79). Compared with groups S and C, there was a statistically significant reduction of S. mutans in interproximal plaque in group X. The results suggest that xylitol chewing gum can prevent dental caries of deciduous dentition, and may be a little more effective than a sorbitol-containing product in controlling some caries-associated parameters in kmdergarten-age subjects.

Total information system for books management exist in many forms. We present total information system for books management which is applied to several different sources, e.g., administrator security login, statistics about the present state of lending, printing management, and convenient GUI(Graphic User Interface) environment.

居延漢簡校釋(6)

韓延錫 중국어문연구회 2001 中國語文論叢 Vol.20 No.-

In this dissertation I tried the interpretations of some Chinese characters (in 居延漢簡) which are not translated or need the supplementary translation, 邸 in "邸校" and 拘 in 拘校 are a loan word of 抵 and 抵校 means'to examine dishonestly.' 區 in "區處" means'to hide'and 處 means 'to come and go.' □ in "□官自□" is a loan word of 繫. □ in "又□疆積三十日" means 'to make efforts diligently.' □ also means 'to make efforts.' 械繫 and 械□ have the same meaning. □ is a loan word of 繫 and means 'to restraint.' 械 originally meant the implements of punishment such as handcuffs or shackles. But here it means 'to confine(拘禁).' 繫 in 校繫 is a loan word of 械 and means 'to reign.' 拘 in "拘迫" is a loan word of 句 and means '句當.' 言 in "言多所服若" means 'orders' or 'directions' and 服若 means 'to obey.' Both 服 and 若 have the meaning of 'obedience.' 口社 in "]大口社=" means 'gathering in crowds 'or' a ritual for hunting.' 代 in "母有差代" is a loan word of □ and means'mistake' or 'error'. 共 in "往共口" is the wrong interpretation of 來. 往共 is 往來 and means 'a record of time when soldiers get a leave and go their home.'
