  • Objectives: This study was performed to suggest how to re-establish criterion for toxic substances under the Chemical Control Act (CCA) in South Korea by comparing the GHS (Globally Harmonized System of Classification and Labeling of Chemicals) score and toxic properties. Methods: Toxic substances were classified into seven groups (Acute toxicity (1A), Chronic toxicity (2C), Environmental hazards (3E), Acute toxicity & chronic toxicity (4AC), Chronic toxicity & environmental hazards (5CE), Acute toxicity & environmental hazards (6AE), and Acute toxicity & chronic toxicity & environmental hazards (7ACE)) according to their toxic properties. The GHS score was calculated to sum up five toxicity indicators (health acute toxicity, health repeated toxicity, carcinogenicity, health other chronic toxicity and environmental hazards). Results: The GHS score of 7ACE was higher by 7 times that of 1A. 1A is the only group which has lower than the total GHS score. The highest score was 47, for sodium chromate (CAS no. 7775-11-3), which belongs to group 7ACE. This is classified as acute toxicity, carcinogenicity, germ cell mutagenicity, reproductive toxicity, and acute and chronic environmental hazard. On the other hand, the lowest score was 2.75, which was assigned to 177 chemicals belonging to group 1A. When the health acute toxicity indicator was omitted from the toxic criterion, toxic substances could be divided into the sub-groups 'human chronic hazards group' (HCG) and 'environmental hazards group' (EG) according to their GHS score and properties. Conclusions: The proposed criterion for toxic substances is to establish sub-groups defined as HCG and EG for separate control and that the 1A group be moved to substances requiring preparation for accidents under the CCA.

  • The purpose of this study is to evaluate the effects of multiple cooling systems and different drinking water temperatures (DWT) on the performance of sows and their hair cortisol levels during heat stress. In this study, the effect of four different cooling systems: air conditioner (AC), cooling pad (CP), snout cooling (SC), and mist spray (MS), and two DWT, namely low water temperature (LWT) and high water temperature (HWT) on 48 multiparous sows (Landrace × Yorkshire; 242.84 ± 2.89 kg) was tested. The experiment is based on the use of eight replicas during a 21-days test. Different behaviors were recorded under different cooling treatments in sows. As a result, behaviors such as drinking, standing, and position change were found to be lower in sows under the AC and CP treatments than in those under the SC and MS treatments. Lying behavior increased under the AC and CP systems as compared with that under the SC and MS, systems. The average daily feed intake (ADFI) in sows and weight at weaning in piglets was higher under the AC, CP, and LWT treatments than under the SC, MS and HWT treatments. Sows subjected to SC and MS treatment showed higher hair cortisol levels, rectal temperature, and respiratory rate during lactation than those under AC and CP treatments. Hair cortisol levels, rectal temperature, and respiratory rate were also higher under the HWT than under the LWT treatment. As per the results of this study, the LWT has no significant effect on any of the behavioral factors. Taken together, the use of AC and CP cooling treatment is highly recommended to improve the behavior and to reduce the stress levels in lactating sows.

  • Genome/gene-editing (GE) techniques, characterized by a low technological barrier, high efficiency, and broad application among organisms, are now being employed not only in medical science but also in agriculture/veterinary science. Different engineered CRISPR/Cas9s have been identified to expand the application of this technology. In pig production, GE is a precise new breeding technology (NBT), and promising outcomes in improving economic traits, such as growth, lean or healthy meat production, animal welfare, and disease resistance, have already been documented and reviewed. These promising achievements in porcine gene editing, including the Myostatin gene knockout (KO) in indigenous breeds to improve lean meat production, the uncoupling protein 1 (UCP1) gene knock-in to enhance piglet thermogenesis and survival under cold stress, the generation of GGTA1 and CMP-N-glycolylneuraminic acid hydroxylase (CMAH) gene double KO (dKO) pigs to produce healthy red meat, and the KO or deletion of exon 7 of the CD163 gene to confer resistance to porcine reproductive and respiratory syndrome virus infection, are described in the present article. Other related approaches for such purposes are also discussed. The current trend of global regulations or legislation for GE organisms is that they are exempted from classification as genetically modified organisms (GMOs) if no exogenes are integrated into the genome, according to product-based and not process-based methods. Moreover, an updated case study in the EU showed that current GMO legislation is not fit for purpose in term of NBTs, which contribute to the objectives of the EU's Green Deal and biodiversity strategies and even meet the United Nations' sustainable development goals for a more resilient and sustainable agri-food system. The GE pigs generated via NBT will be exempted from classification as GMOs, and their global valorization and commercialization can be foreseen.

  • Estimation of heading date of paddy rice is laborious and time consuming. Therefore, automatic estimation of heading date of paddy rice is highly essential. In this experiment, deep learning classification models were used to classify two difference categories of rice (vegetative and reproductive stage) based on the panicle initiation of paddy field. Specifically, the dataset includes 444 slanted view images belonging to two categories and was then expanded to include 1,497 images via IMGAUG data augmentation technique. We adopt two transfer learning strategies: (First, used transferring model weights already trained on ImageNet to six classification network models: VGGNet, ResNet, DenseNet, InceptionV3, Xception and MobileNet, Second, fine-tuned some layers of the network according to our dataset). After training the CNN model, we used several evaluation metrics commonly used for classification tasks, including Accuracy, Precision, Recall, and F1-score. In addition, GradCAM was used to generate visual explanations for each image patch. Experimental results showed that the InceptionV3 is the best performing model in terms of the accuracy, average recall, precision, and F1-score. The fine-tuned InceptionV3 model achieved an overall classification accuracy of 0.95 with a high F1-score of 0.95. Our CNN model also represented the change of rice heading date under different date of transplanting. This study demonstrated that image based deep learning model can reliably be used as an automatic monitoring system to detect the heading date of rice crops using CCTV camera.

  • Hepatitis C virus (HCV) infection is a major health problem worldwide and its eradication is mandatory. Direct acting HCV polymerase inhibitors, such as Sofosbuvir (SOF), is an effective regimen. However, it has some side effects like mutagenesis, carcinogenesis, and the impairment of testicular function. It is important to evaluate the safety of SOF on the ovary, as there are no studies yet. Increasing the production of Reactive Oxygen Species (ROS), causes oxidative stress, which affects ovulation process, female reproduction, and fertility. Accumulation of SOF in the cells was demonstrated to promote ROS generation. Vitamin E (Vit E) is an antioxidant agent that has an essential role in the female reproductive system, its deficiency can cause infertility. We explored the effect of SOF treatment alone and co-treated with Vit E on ovarian ROS level and ovarian morphology experimentally using biochemical and immunohistochemical studies. Significant changes in oxidative stress markers; nitric oxide and malondialdehyde lipid peroxidation, antioxidant enzymes; catalase, super oxide dismutase, and reduced glutathione, proliferating markers; proliferation cell nuclear antigen and Ki-67 antigen and caspase 3 apoptotic marker were demonstrated. It was shown that where SOF induced oxidative stress, it also aggravated ovarian dysfunction. The essential role of Vit E as an antioxidant agent in protecting the ovarian tissue from the effect of oxidative stress markers and preserving its function was also displayed. This could be guidance to add Vit E supplements to SOF regimens to limit its injurious effect on ovarian function.

  • Agriculture has played a significant role in the national economy, contributing to food security, driving economic growth, and safeguarding the dietary habits of the population. Korean agriculture has been compelled to focus on intensive farming due to its limited cultivation area, excessive input costs, and the limitations of agricultural mechanization. In the Republic of Korea (R.O.K), the concept of environmentally friendly animal agriculture began to be introduced in the early 2000s. This concept ultimately aims to cultivate sustainable animal agriculture (SAA) through environmentally friendly production practices, ensuring the healthy rearing of animals to supply safe animal products. Despite the government's efforts, there are still significant challenges in implementing environmentally friendly agriculture and SAA in the R.O.K. Therefore, the objective of this review is to establish the direction that the animal agriculture sector should take in the era of climate crisis, and to develop effective strategies for SAA tailored to the current situation in the R.O.K by examining the trends in SAA in the U.S. The animal agriculture sector in the U.S. has been working towards creating a SAA system where humans, animals, and the environment can coexist through government initiatives, industry research, technological support, and individual efforts. Efforts have been made to reduce emissions like carbon, and improve factors affecting the environment such as the carbon footprint, odor, and greenhouse gases associated with animal agriculture processes for animals such as cattle and pigs. The transition of the U.S. towards SAA appears to be driven by both external goals related to addressing climate change and the primary objectives of responding to the demand for safe animal products, expanding consumption, and securing competitiveness in overseas export markets. The demand for animal welfare, organic animal products, and processed goods has been increasing in the U.S. consumer market. A major factor in the transformation of the U.S. animal agriculture sector in terms of livestock specifications is attributed to environmentally friendly practices such as high-quality feed, heat stress reduction, improvements in reproductive ability and growth period reduction, and efforts in animal genetic enhancement.

  • Glucocorticoids play a physiologic role in the adult male reproductive functions, modulating gonadal steroid synthesis and spermatogenesis, through the glucocorticoid receptor (GR). The expression of GR has been described in several key testicular cell types, including somatic cells and early germ cell populations. Nothing is known on GR in human spermatozoa. Herein, we explored the GR expression and its possible role in normal and testicular varicocele semen samples from volunteer donors. After semen parameter evaluation by macro- and microscopic analysis, samples were centrifuged; then spermatozoa and culture media were recovered for further investigations. By western blotting and immunofluorescence analyses we evidenced for the first time in spermatozoa the presence of GR-D3 isoform which was reduced in sperm from varicocele patients. By treating sperm with the synthetic glucocorticoid dexamethasone (DEXA), we found that survival, motility, capacitation, and acrosome reaction were increased in both healthy and varicocele samples. GR involvement in mediating DEXA effects, was confirmed by using the GR inhibitor mifepristone (M2F). Worthy, we also discovered that sperm secretes different cortisol amounts depending on its physio-pathological status, suggesting a defence mechanism to escape the immune system attach in the female genital tract thus maintaining the immune-privilege as in the testis. Collectively, our data suggests a role for glucocorticoids in determining semen quality and function, as well as in participating on sperm immune defensive mechanisms. The novelty of this study may be beneficial and needs to take into account in artificial insemination/drug discovery aimed to enhancing sperm quality.

  • 일반적으로 올인-올아웃 시스템은 농장에서 양돈 생산성을 개선할 수 있는 최선의 사양관리방법으로 알려져 있으며, 그룹관리 방식은 질병의 전파를 차단하고, 질병 순환 고리를 제거할 수 있는 올인-올아웃 시스템을 자연스럽게 적용할 수 있는 사양 관리 방법 중 하나이다. 그룹관리는 양돈장의 모든 총두수, 돈사 시설 등을 고려하였을 때, 그룹의 크기와 관리 주간의 차이에 따라 다양한 방식이 존재한다. 모돈의 주간관리와 그룹관리 방법은 농장의 상황에 따라 다양한 장단점이 존재하며, 시설과 모돈 수 등을 고려하여 가장 적합한 관리 방법을 농장에 적용하여야 할 것이다. 모돈의 그룹관리는 형태에 따라 2, 3, 5, 7 주간 그룹관리 등으로 나눌 수 있지만, 이중에서도 3주간 그룹관리는 주간관리, 2, 5, 7 주간 관리에 비해 돈군의 흐름과 모돈의 번식 생리를 적절히 활용하고, 관리자의 작업효율을 높일 수 있는 관리 방법이라고 할 수 있겠다. 임신이 되지 않은 모돈은 3주 간격의 발정주기를 갖게 되므로, 이 같은 모돈의 생리를 효과적으로 이용하는 방법이 모돈들을 3주간 그룹관리체계로 관리하는 것이다. 3주간 그룹관리는 모돈의 번식능력 향상은 물론, 전체 양돈장에 올인-올아웃에 의한 사양 관리가 이루어질 수 있도록 하여 PMWS, PRRS, PRDC, PED 등 국내에 만연하고 있는 질병을 예방하고, 유럽의 양돈선진국들에 비해 현저히 낮은 국내의 양돈 생산성을 개선시킬 수 있는 대안이 될 수 있다고 하겠다.

  • The success of the family planning program in Korea is reflected in the decrease in the growth rate from 3.0% in 1962 to 2.0% in 1971, and in the decrease in the fertility rate from 43/1,000 in 1960 to 29/1,000 in 1970. However, it would be erroneous to attribute these reductions entirely to the family planning program. Other socio-economic factors, such as the increasing age at marriage and the increasing use of induced abortions, definitely had an impact on the lowered growth and fertility rate. Despite the relative success of the program to data in meeting its goals, there is no room for complacency. Meeting the goal of a further reduction in the population growth rate to 1.3% by 1981 is a much more difficult task than any one faced in the past. Not only must fertility be lowered further, but the size of the target population itself will expand tremendously in the late seventies; due to the post-war baby boom of the 1950's reaching reproductive ages. Furthermore, it is doubtful that the age at marriage will continue to rise as in the past or that the incidence of induced abortion will continue to increase. Consequently, future reductions in fertility will be more dependent on the performance of the national family planning program, with less assistance from these non-program factors. This paper will describe various approaches to help to the solution of these current problems. 1. PRACTICE RATE IN FAMILY PLANNING In 1973, the attitude (approval) and knowledge rates were quite high; 94% and 98% respectively. But a large gap exists between that and the actual practice rate, which is only 3695. Two factors must be considered in attempting to close the KAP-gap. The first is to change social norms, which still favor a larger family, increasing the practice rate cannot be done very quickly. The second point to consider is that the family planning program has not yet reached all the eligible women. A 1973 study determineded that a large portion, 3096 in fact, of all eligible women do not want more children, but are not practicing family planning. Thus, future efforts to help close the KAP-gap must focus attention and services on this important large group of potential acceptors. 2. CONTINUATION RATES Dissatisfaction with the loop and pill has resulted in high discontinuation rates. For example, a 1973 survey revealed that within the first six months initial loop acceptance. nearly 50% were dropouts, and that within the first four months of inital pill acceptance. nearly 50% were dropouts. These discontinuation rates have risen over the past few years. The high rate of discontinuance obviously decreases the contraceptive effectiveness. and has resulted in many unwanted births which is directly related to the increase of induced abortions. In the future, the family planning program must emphasize the improved quality of initial and follow-up services. rather than more quantity, in order to insure higher continuation rates and thus more effective contraceptive protection. 3. INDUCED ABORTION As noted earlier. the use of induced abortions has been increase yearly. For example, in 1960, the average number of abortions was 0.6 abortions per women in the 15-44 age range. By 1970. that had increased to 2 abortions per women. In 1966. 13% of all women between 15-44 had experienced at least one abortion. By 1971, that figure jumped to 28%. In 1973 alone, the total number of abortions was 400,000. Besides the ever incre.sing number of induced abortions, another change has that those who use abortions have shifted since 1965 to include- not. only the middle class, but also rural and low-income women. In the future. in response to the demand for abortion services among rural and low-income w~men, the government must provide and support abortion services for these women as a part of the national family planning program. 4. TARGET SYSTIi:M Since 1962, the nationwide target system has been used to set a target for each method, and the target number of acceptors is then apportioned out to various sub-areas according to the number of eligible couples in each area. Because these targets are set without consideration for demographic factors, particular tastes, prejudices, and previous patterns of acceptance in the area, a high discontinuation rate for all methods and a high wastage rate for the oral pill and condom results. In the future. to alleviate these problems of the methodbased target system. an alternative. such as the weighted-credit system, should be adopted on a nation wide basis. In this system. each contraceptive method is. assigned a specific number of points based upon the couple-years of protection (CYP) provided by the method. and no specific targets for each method are given. 5. INCREASE OF STERILIZA.TION TARGET Two special projects. the hospital-based family planning program and the armed forces program, has greatly contributed to the increasing acceptance in female and male sterilization respectively. From January-September 1974, 28,773 sterilizations were performed. During the same time in 1975, 46,894 were performed; a 63% increase. If this trend continues, by the end of 1975. approximately 70,000 sterilizations will have been performed. Sterilization is a much better method than both the loop and pill, in terms of more effective contraceptive protection and the almost zero dropout rate. In the future, the. family planning program should continue to stress the special programs which make more sterilizations possible. In particular, it should seek to add the laparoscope techniques to facilitate female sterilization acceptance rates. 6. INCREASE NUMBER OF PRIVATE ACCEPTORS Among the current family planning users, approximately 1/3 are in the private sector and thus do not- require government subsidy. The number of private acceptors increases with increasing urbanization and economic growth. To speed this process, the government initiated the special hospital based family planning program which is utilized mostly by the private sector. However, in the future, to further hasten the increase of private acceptors, the government should encourage doctors in private practice to provide family planning services, and provide the contraceptive supplies. This way, those do utilize the private medical system will also be able to receive family planning services and pay for it. Another means of increasing the number of private acceptors, IS to greatly expand the commercial outlets for pills and condoms beyond the existing service points of drugstores, hospitals, and health centers. 7. IE&C PROGRAM The current preferred family size is nearly twice as high as needed to achieve a stable poplation. Also, a strong boy preference hinders a small family size as nearly all couples fuel they must have at least one or more sons. The IE&C program must, in the future, strive to emphasize the values of the small family and equality of the sexes. A second problem for the IE&C program to work. with in the: future is the large group of people who approves family planning, want no more children, but do not practice. The IE&C program must work to motivate these people to accept family planning And finally, for those who already practice, an IE&C program in the future must stress continuation of use. The IE&C campaign, to insure highest effectiveness, should be based on a detailed factor analysis of contraceptive discontinuance. In conclusion, Korea faces a serious unfavorable sociodemographic situation- in the future unless the population growth rate can be curtailed. And in the future, the decrease in fertility will depend solely on the family planning program, as the effect of other socio-economic factors has already been maximumally felt. A second serious factor to consider is the increasing number of eligible women due to the 1950's baby boom. Thus, to meet these challenges, the program target must be increased and the program must improve the effectiveness of its current activities and develop new programs.

  • 성호르몬은 lacrimal system, corneal anatomy and disease, aqueous humor dynamics and glaucoma, crystalline lens and cataract, retinal disease를 포함한 안과영역의 다양한 부위에 영향을 끼칠 수 있다. Androgen은 전신에 걸친 sebaceous glands의 발달, 분화, 지질생성 등에 관여하므로 androgen deficiency는 meibomian gland의 기능장애와 건성안에서 증발을 더욱더 심화시킬 수 있는 것으로 알려져 있다. 반면에 estrogens은 sebaceous glands의 크기, activity, 지질생성을 감소시켜 meibomian gland에서는 androgen과 반대되는 작용을 할 가능성이 있다. 성호르몬은 또한 각막의 구조와 질병경과에도 영향을 줄 수 있는데, 각막이 월경주기 제2일째 및 배란주위기에 두꺼워지며, 폐경 여성에서 여성호르몬 치료 시 각막두께가 증가한다는 사실은 estrogen levels과 각막 두께와의 연관을 시사하는 소견이라고 하겠다. Fuch's dystrophy 역시 폐경 후 여성에서 더 흔히 관찰되어, 나이에 따른 호르몬 변화가 그 원인 중 하나로 지목되고 있으며, vernal keratoconjunctivitis 환자의 각막조직에서는 estrogen과 progesterone 수용체의 overexpresson이 발견되어 역시 이들 질환에서의 성호르몬의 역할을 시사한다고 할 수 있겠다. 성호르몬은 안압에도 영향을 미칠 수 있는데, intraocular pressure와 혈중 luteinizing hormone, follicular stimulating hormone (FSH), estrone, estradiol, progesterone, testosterone과는 연관이 없는 것으로 보고한 결과도 있으나, 혈중 progesterone의 경우 특히 임신중인 여성에서 안압과의 연관관계가 보고되었으며, 또한 폐경 여성에서 혈중 남성호르몬 농도가 높을수록 안압이 상승하는 경향이 있음이 보고되었다. 한편 'Female sex'는 모든 종류의 백내장의 위험요소인 것으로 알려져 있다. 백내장으로 진단받은 여성의 경우 호르몬 측정 시 연령등을 보정하고도 폐경기에 가까운 호르몬 수치를 보였으며, 이들 백내장 환자군내에서는 estradiol과 FSH 농도 사이에 유의한 음의 상관관계가 보고되었다. 또한 DHEAS의 경우 백내장 위험도를 감소시키는 것으로 보고되었고, 그 기전으로 전구호르몬인 DHEA의 역할을 제시되고 있는데. 즉 백내장의 주요 기전 중 하나인 oxidative stress를 감소시키는 antioxidant activity를 DHEA가 보이기 때문일 것으로 추정되고 있다. 성호르몬은 망막 내 혈관의 흐름에도 영향을 줄 수 있는 것으로 알려져 있는데, 안구 내 혈류에서 여성호르몬의 긍정적인 효과와 남성호르몬의 부정적인 효과가 보고되었고, age-related macular degeneration (AMD)의 경우, estradiol이 ER-$\beta$ 수용체를 통해 보호효과가 있음이 보고되어, ER-$\beta$ 수용체가 향후 AMD 치료에서 치료적 target이 될 수도 있을 것으로 알려지고 있다. 또한 DHEAS의 경우 AMD 위험도를 증가시킬 가능성이 있으며, 당뇨로 진단받은 환자에서는 혈중 testosterone 농도는 당뇨병성 망막병증의 진행과 연관이 있는 것으로 보고되었다. 성호르몬은 안과영역의 다양한 질환과의 연관관계는 아직 추가연구가 필요한 실정이나 다양한 성호르몬이 안질환의 발생 및 경과에 영향을 줄 가능성이 있으며, 이와 같은 연관관계가 규명된다면 추후 호르몬을 통해 질환의 경과 및 예방의 가능성이 제시될 수도 있을 것으로 사료된다. 특히 폐경이후 다양한 안질환이 증가한다는 기존의 연구결과들을 고려 시, 안과영역에 있어 폐경기 여성호르몬 치료의 긍정적인 역할에 관해서는 지속적인 관심이 요구된다고 하겠다.
