Infection of the disease that are propagated through a dead body of management and transportation must be very careful. Risk of infection that can occur between the deceased body and funeral directors, guideline of the preparation room and infection route of infection source has been studies in Korea. But the funeral director's working circumstances and infection blocking facility of the funeral home has not been studied in Korea. So we are investigated about the state of the working circumstances and Infection blocking facility within Metropolitan, Chungcheong and Gyeongsang regions in Korea. The result is as follows. The funeral directors have shown that there is difficult to get safe protection from infection. The personal hygiene of funeral directors and the infection blocking facility should be strengthened institutionally. We are thought to require more in-depth research about the working circumstances of funeral director and the infection blocking facility.

2-부톡시에탄올(2-butoxyethanol)에 대한 생물학적 노출지수 설정에 필요한 자료는 상당수 존재한다. 다양한 실험실 및 직업적 현장연구는 2-butoxyethanol에 노출된 후 소변에서 butoxyacetic acid의 배설을 조사하여 생물학적 노출지수를 구축할 데이터베이스를 제공하였다. 실험실 연구는 작업시간 동안보다는 짧은 시간을 노출시킨다. 휴식 중에 실시한 실험 자료들을 20ppm에 8시간 노출로 외삽하면 작업시작 종료 시점의 소변 중 butoxyacetic acid의 농도가 각각 192, 272, 190 mg/g creatinine이었다. 작업부하 30 watts와 50 watts의 연구 결과를 외삽하면 각각 304 butoxyacetic acid/g creatinine과 313 butoxyacetic acid/g creatinine이었다. 작업현장 연구는 소변을 가수분해시킨 후 총 butoxyacetic acid의 검출 범위가 광범위할 것으로 예상된다. 이러한 외삽의 결과는 일반적으로 1ppm 미만의 노출에서 나온 것이라는 점에 유의해야 한다. 피부 흡수의 가능성과 2-butoxyethanol의 상대적으로 낮은 휘발성을 감안할 때 현장 연구에서는 피부 경로가 흡입 연구보다 더 중요할 수 있다. 따라서 현장 조사는 휴식을 취한 자원봉사자를 대상으로 실시한 흡입 연구와 비교하면 소변 중 butoxyacetic acid 농도를 과대평가하는 경향이 있다. 활용 가능한 시뮬레이션 연구에서 휴식 시 2-butoxyethanol의 TLV-TWA 20ppm에 8시간 전신(흡입과 피부) 노출되는 경우 가수분해된 총 butoxyacetic acid가 210 mg/g creatinine이 예상되고 작업부하 50 watts에서는 373 mg/g creatinine이 예측된다. 50 watts의 작업량으로 20ppm에서 8시간 노출되는 경우 생물학적 노출지수(BEI)는 약 400 mg/g creatinine일 것이다. 그러나 생물학적 노출지수는 외삽에 대한 불확실성, 심각한 피부 노출 및 작업장 노출평가 자료의 부족을 반영하여 200 mg butoxyacetic acid/g creatinine으로 설정하였다. 인용한 자료들의 한계에도 불구하고 자원 봉사자 연구와 시뮬레이션 연구의 자료들이 일치성이 있었다. 연구에 따르면 butoxyacetic acid는 측정 가능한 양으로 존재하며 작업 교대 중에 검출될 수 있는 충분한 시간의 반감기를 가지고 있다. Sakai 등의 연구 자료와 일부 모델링 자료에서 노출농도가 높은 경우 주중에 약간의 축적 가능성을 보고하였지만 작업장에서 일반적으로 노출되는 농도 범위에서는 누적이 예상되지 않으며 작업 종료 후에 소변시료를 채취하는 것이 바람직하다. 대다수의 연구에서 소변 중 butoxyacetic acid 농도 수준의 개인 간 다양성을 보고하였다. 또한 대부분의 작업현장 연구에서는 2-butoxyethanol의 주변 환경 농도수준과 소변 중 butoxyacetic acid 수준에 유의한 상관관계를 발견하지 못하였다. 상호 연관성이 결여된 원인은 대부분 피부 노출의 영향으로 추정하였다. 개인 보호 장갑을 착용한 근로자들에게서는 유의한 상관관계가 발견되었다.

A tear lens formed by between back surface of spherical rigid gas permeable(RGP) contact lens and front surface of cornea shows an excellent correction effect of astigmatism. To study an effects of tear lens power using spherical RGP lens and therefore to utilize them in clinical procedures, we analyze a change of the total astigmatism, the cornea astigmatism, and the residual astigmatism, we derive the following conclusion. 1. Almost all refractive astigmatism below than 2.00D present fully corrected. Thereby resulting good visual acuity. Refractive astigmatism higher than 2.50D show under-corrected and apparent decrease of visual acuity if it is higher than 3.00D. 2. Amount of corneal astigmatism below than 2.50D show acceptable under-corrected while higher than 3.000 present unacceptable visual acuity. 3. An estimated residual astigmatism is not revealed as it is : but it is reduced when it incorporate to refractive astigmatism.

Purpose : The purpose of this study was to determine the effect of book bag handling styles and types of footwear on muscle activation of erector spine muscles and calf muscles. Methods : Ten participants took off their book bags and used sneakers to walk on a treadmill for 30 minutes. The following day, 10 participants put on their backpack with 10% of the weight and used sneakers to walk on the treadmill for 30 minutes. On the last day, 10 participants put on their backpack with 10% of the weight and used formal shoes to walk on the treadmill for 30 minutes. After walking on the treadmill at 3 mph for thirty minutes, we measured muscle activation in erector spine muscles and calf muscles. Results : The results of this study showed the activation of the erector spine muscles and the calf muscles significantly increased when walking with a book bag and the activation of the erector spine muscles and the calf muscles significantly increased when walking in formal shoes. Conclusion : Using a backpack and formal shoes increase muscle activity of erector spine muscles and calf muscles. The results of this study indicate that not using a backpack and wearing sneakers are more beneficial than that using a backpack weighted 10% and wearing formal shoes and can be recommended to adult women by clinicians.

Purpose: Current gas-mask is very uncomfortable structure for spectacles wearer. Improving this problem can aid military men and firemen to protect themselves and rescue other person. Methods: we changed the structure from dual type of outward lens and inward lens into a single type structure. we attached acrylic frame to gas-mask instead of outward lens and protected the gas inflow by shutting the gab of lens and frame using silicon shield, and made the frame "S" style for removing astigmatism and maintaining of vertex distance. Results: It was possible to correct visual acuity and gas shield, and could changed the lens like a common spectacles. The new type of gas-mask spectacles could remove 0.53D~1.78D astigmatism occurred from the slant of eyesight and lens surface, 0.07D~0.66D overcorrection occurred from short vertex distance, and 0.1D~0.3D astigmatism occurred from pantoscopic angle. Conclusion: Because new type of gas-mask spectacles had clear visual field, it was expected to improve fighting power and rescue ability.

In order to combat the spread of COVID-19, on January 30, 2020, the World Health Organization declared that the spread of COVID-19 has met the criteria of a "Public Health Emergency of International Concern" under Article 1 of the International Health Regulations(2005) and proposed a variety of preliminary recommendations to fight against the pandemic accordingly. All of a sudden, people are ordered to wear face-masks in public-which is forbidden for different reasons in many jurisdictions. Of course, the legal world was hit by the virus as well. Needless to mention that where economic and social life will change so drastically, the legal world will change(ex. virtual hearing) as well. Most probably, it will not ever be the same after COVID-19. And where the whole legal world will change, it is easy to state the obvious, namely that COVID-19 has and will have an impact on international arbitration as well. This paper will describe how international arbitration is dealing with this new challenge.
