This study was conducted to assess the exposure risk through inhalation to baby powder for babies and adults under simulated conditions. Baby powder was applied to a baby doll and the amount of baby powder consumed per application was estimated. The airborne exposure to baby powder during application was then evaluated by sampling the airborne baby powder near the breathing zones of both the baby doll and the person applying the powder (the applicator). The average amount of baby powder consumed was 100 mg/application, and the average exposure concentration of airborne baby powder for the applicator and baby doll was 0.00527 mg/$m^3$ (range 0.00157~0.01579 mg/$m^3$) and 0.02207 mg/$m^3$ (range 0.00780~0.04173 mg/$m^3$), respectively. When compared with the Occupational Exposure Limit of 2 mg/$m^3$ set by the Korean Ministry of Labor and the Threshold Limit Value (TLV) of 2 mg/$m^3$ set by the ACGIH (American Conference of Governmental Industrial Hygienists), the exposure concentrations were much lower. Next, the exposure to asbestos-containing baby powder was estimated and the exposure risk was assessed based on the lung asbestos contents in normal humans. As a result, the estimated lung asbestos content resulting from exposure to asbestos-containing baby powder was found to be much lower than that of a normal Korean with no asbestos-related occupational history.

유아용 파우더는 유아의 기저귀 발진을 방지하거나 기타 다른 화장용 파우더의 원료로 사용되고 있고 그 주성분은 일반적으로 광물질인 탈크 분말이 주로 이용되고 있다. 탈크 분말은 사용에 있어 호흡기로 흡입하게 되면 심각한 폐 손상 등을 야기하여 위험하다고 알려져 있다. 쌀 분말을 이용한 유아용 파우더를 개발하기 위하여 3종류의 쌀 품종이 사용되었고, 곱게 분쇄하였다. 최적의 유아용 파우더를 얻기 위해 몇 단계의 분쇄과정을 거쳤고, 파우더에 대한 오일과 실리콘 코팅 처리 전후의 파우더 입자크기, 생리활성, 색차, 수분 흡수율 등의 파우더 특성을 검정하였다. 분말의 색택과 입자 크기 등의 특성에서 고아미 품종의 파우더가 우수한 특성을 보였고, 전자현미경 관찰결과 오일과 실리콘 오일 코팅한 쌀 파우더가 탈크에 비해 둥글고 부드러운 모양을 나타내었다. 또한 오일과 실리콘 코팅에 의해 평균 입자크기가 줄어드는 현상을 나타내었으며 쌀 분말의 단점인 수분흡수를 차단하여 파우더로서 우수한 특성을 유지함을 보였다.

In this study, silk gland powder of silkworm were investigated to see the possibility for baby powder cosmetics materials. To test possibility as a baby powder cosmetics, total content rate of amino acids, DPPH free radical scavenging assay, MTT assay, and clinical trial were done. According to the result of the analysis of the amino acids of silk gland powder, serin (26.77%) content was the highest and asparatic acid (15.47%), and glycine (9.62%) were followed. DPPH free radical scavenging activity of silk gland powder was lower than vitamin C by 82.3% and 97%, respectively, which is relatively good. Moisture effect were increased in silk gland powder compared to control cosmetics by 50%. Also, silk gland powder was classified as a practically non-irritating material based on the score 0.05 of primary irritation index. Thus, these results suggest that silk gland powder of silkworm may have beneficial properties as a material for baby powder cosmetics.

비열처리가공기술 중 하나로 새롭게 주목받고 있는 초고압처리를 반고형 형태의 친환경 유기농 이유식 제조에 적용하여 완제품 형태로 제조 후 냉장 조건으로 저장하여 저장기간에 따른 제품 안전성을 조사하였다. 가열 처리를 하지 않고 550 MPa 압력에서 3분 동안 초고압 처리하여 냉장 상태로 15일 동안 저장한 결과, 일반세균과 대장균 모두 검출되지 않아 미생물학적 안전성을 확인할 수 있었으며, 초고압 처리를 하지 않은 대조군에서 일반세균이 $2.54{\times}10^3$, $7.85{\times}10^2$ CFU/g 수준으로 검출되었던 것과 비교했을 때 초고압 처리를 하는 것이 제품의 신선도를 살리고 제품의 안전성을 유지하기 위해 적합한 처리법이라고 판단되어진다. 초고압 처리를 통한 물성 변화는 처리 전 대조구와 점도, 스푼풀 현상을 비교하였을 때 큰 차이가 나타나지 않는 것으로 나타났고, 그 결과 사과의 신선한 상태를 유지하고 미생물학적 안전성 역시 유지하면서 냉장상태로 약 2주간 저장이 가능한 친환경 반고형 이유식을 제조할 수 있었다.

간편식 형태의 이유식 중 죽 44건, 진밥 40건, 퓌레 11건, 분말 6건으로 총 101건의 무기질(철, 아연, 칼슘, 마그네슘) 함량을 마이크로웨이브 분해장치로 분해하여 ICP-OES로 분석하였다. 무기질의 유형별 평균 함량은 철 0.05-0.45 mg/100 g(mg/10 g, 분말), 아연 0.06-0.29 mg/100 g(mg/10 g, 분말), 칼슘 3.07-6.65 mg/100 g(mg/10 g, 분말), 마그네슘 2.46-5.93 mg/100 g(mg/10 g, 분말)으로 나타났다. 철, 아연, 칼슘, 마그네슘의 권장섭취량(KDRIs)과 비교하였을 때 권장섭취량 대비 각각 2.74-22.35%(평균 11.10%), 5.94-28.95%(평균 21.91%), 3.07-6.65%(평균 4.47%), 13.42-38.95%(평균 22.85%)이었다. 시판되는 간편 이유식만으로는 생후 6개월 이후 각각의 무기질 권장섭취량을 충분히 섭취할 수 없어 조제식이나 모유를 통한 영양소 섭취가 필요하다. 충분한 무기질 섭취를 위해서는 각각 영양소의 주요 급원식품을 파악하고 부족한 영양소를 섭취할 수 있는 간편 이유식을 선택하는 것을 권장한다. 아울러 제조회사에서는 우리나라 영유아시기에 부족해지기 쉬운 철, 칼슘 등의 영양소를 강화한 재료를 이유식 제조에 사용·표기하여 영유아의 성장발달에 필요한 영양소가 균형 있게 공급될 수 있도록 해야 할 것이다.

The modification of rice powder was attempted by treatment of acetic acid and epichlorohydrin to improve the functional properties of baby food. The initial gelatinization temperature of rice powder determined by amylograph was decreased from $79.5^{\circ}C$ to $63^{\circ}C$ by modification. The apparent and maxium viscosity of rice paste at $95^{\circ}C$ before and after modification were increased from 92B.U. to 236B.U. and from 100B.U. to 202B.U., respectively. The light transmittance of modified rice paste was increased from the temperature of $60^{\circ}C$ and by increasing the degree of substitution at the fixed temperature, while decrease more or less by the treatment of epichlorohydrin. The degree of retrogradation of the paste was decreased from 28.7 to 18.0 upon modification. The rate of syneresis of modified rice powder was decreased with increasing the drgree of substitution and ,the extend of epichlorohydrin treatment. Syneresis was not observed when acetylated rice powder whose DS value is 0.048 was treated with 0.25% of epichlorohydrin for the formation of cross-linkage. The addition of modified rice powder in preparation of semi-solid type infant food could improve the quality without lowering overall digestibility.

Humans have a long history of asbestos use. There are reports from the Roman era, of asbestos victims among the slaves who worked in asbestos mines. The fact that asbestos can induce lung cancer and mesothelioma was verified epidemiologically in the 1960s. Asbestos related diseases are predominantly occupational in nature but can be caused by environmental exposure. Environmental mesothelioma is mainly associated with tremolite asbestos and this information comes from many countries including Turkey, Greece, Corsica, New Caledonia and Cyprus. In 1993, the first case of mesothelioma in Korea was reported in an asbestos textile worker. Recently, some asbestos disease victims who lived near an asbestos factory have their cases before the courts. A series of recent asbestos-related events in Korea, for example, the shocking revelation of asbestos containing talc in baby powders have caused the general public to become aware of the health risks of asbestos exposure. Asbestos related diseases are characterized by a long latency period, especially, mesothelioma which has no threshold of safety. Hence the best strategy for preventing asbestos related diseases is to decrease asbestos exposure levels to as low as possible.

한국산 바지락으로부터 새로운 렉틴을 아세톤파우더, 황산암모늄 침전, 친화력 크로마토그라피 및 FPLC의 이온교환 크로마토그라피법으로 분리 정제하였다. 이 렉틴은 사람의 적혈구를 비특이적으로 응집시켰으며, 생쥐와 토끼의 적혈구 및 생쥐의 복수 Sarcoma 180 세포를 응집시키지 않았고 사람의 말초혈관 임파구도 분열 촉진시키지 못하였다. 전기영동상에서 하나의 주된 띠로 나타났으며 분자량은 Biogel P-300겔 여과에서 131,000, SDS 전기영동상에서는 125,000으로 나타났다. Subunit는 33,000과 30,000의 다른 폴리펩타이드로 tetramer로 추정된다. EDTA에 의해서 활성이 저해된 바지락 렉틴은 $Ca^{++}$과 $Mn^{++}$에 의하여 적혈구 응집력이 회복되었다. 또한 이 렉틴은 약 4.2% 중성당을 함유한 당단백질임이 확인되었다.

The most commonly used infant formulas contain lactose originating from cow milk. Goat milk has recently been claimed to be nutritionally more effective for infants than other milks. In baby foods, much emphasis is placed on the concentrations of intestinal microflora-promoting oligosaccharides, which are generally transferred into lactose from milk during crystallization process. Here we show that higher level of free sialic acid is present in goat lactose powder compared to cow lactose powder. Without proteinase K treatment, the amount of 3-sialyllactose and 6-sialyllactose were similar in goat and cow lactose powders. However, after proteolysis, 6-sialyllactose was present at higher levels in goat than in cow lactose powder. Galactooligosaccharides, a group of prebiotics, are present in milk in the form of glycoproteins. Galactooligosaccharide content was also higher in goat lactose powder than in cow lactose powder.
