박지후,윤호백,정하연,김태일,원정일 경상대학교 농업생명과학연구원 2018 농업생명과학연구 Vol.52 No.4

본 연구는 Holstein 암소 34두로부터 조사된 체고 측정 기록에 대해 세 가지 비선형 성장곡선을 적용하여 성장모형을 추정하고, 추정된 성장모형의 모수를 이용하여 Holstein 암소의 성장특성에 대한 기초자료를 제공하고자 실시하였다. Gompertz, von Bertalanffy 및 Logistic 모형으로 추정된 성장곡선 함수식은 각각 Ht=457.2e-1.705e-0.02552t, Ht=465.4(1-0.417e-0.0.01724t)3 및 Ht=1079.1(1+12.682e-0.04275t)-1이였다. 최대성장시기를 나타내는 변곡점( )은 Gompertz, von Bertalanffy 및 Logistic에 대해 각각 616.039, 419.253 및 1759.728일로 추정되었다. 변곡점에서의 체고 증가속도 추정치는 Gompertz, von Bertalanffy 및 Logistic에 대해 각각 0.138, 0.109 및 0.366cm으로 나타났으며, 변곡점에서의 체고는 각각 176.5, 137.9 및 539.5cm으로 추정되었다. 오차 평균 제곱합의 결과를 보면 Logistic, von Bertalanffy 그리고 Gompertz 모형 순으로 적합도가 좋은 것으로 판단된다. This study was conducted to estimate the growth parameters of Holstein cows and to compare their growth characteristics based on withers height-age data of Holstein cows of 34 heads from National Institute of Animal Science in Korea. Three models(Gompertz, von Bertalanffy and Logistic model) were considered for analyses. The estimated growth functions for Gompertz, von Bertalanffy and Logistic models were Ht =457.2e-1.705e-0.02552t, Ht =465.4(1-0.417e-0.0.01724t)3 and Ht =1079.1(1+12.682e-0.04275t)-1, respectively. The estimated average infection points(ti) showing maximum growth rate were 616.039, 419.253 and 1759.728 day of age, respectively, using on Gompertz, von Bertalanffy and Logistic model. Average gain at inflection for Gompertz, von Bertalanffy and Logistic model were estimated 0.138, 0.109 and 0.366 cm/day, respectively. The estimated withers height at inflection for Gompertz, von Bertalanffy and Logistic model were 176.5, 137.9 and 539.5 cm, respectively. In the study, the Logistic model having a variable point of inflection fitted the best for data of Holstein cows.

This study was conducted to evaluate the effect of feeding additional cobalt (Co) on the physiologic characteristics of Holstein cows. Ten multiparous, lactating Holstein cows (727.2±79.1kg) were randomly assigned to 1 of 2 experimental groups. Five cows were fed 0.1 mg/kg (control group, essential cobalt requirement based on NRC), and the other five cows were fed 0.8 mg/kg (treatment group). Co-glucoheptonate was used for cobalt supplementation. In addition, to examine the effect of environmental temperature, tests were performed twice under a thermoneutral condition (THI 67.2 ± 5.46) and a high-temperature condition (THI 79.09 ± 3.85) over two weeks in May and July 2022. Feeding extra cobalt in the high-temperature environment lowered ruminal temperature (Control: 39.5 9℃ ± 0.11, Treatment: 39.47℃ ± 0.09; p ≤0.001). Furthermore, under both temperature conditions, the control group had a higher rectal temperature than the treatment group (p <0.001). These results could be used as management guides to improve dairy cow stress in high-temperature environments.

日本占領期インドネシアの二言語雑誌<<ジャワ·バル>>に載せられた文学作品とその意味

This study focused on the relationship between Japan and Indonesia, which has been studied from a Japanese perspective or in Southeast Asian research, and analyzed the basic data 『Jawa·Baroe』 based on the new definition of Indonesian Japanese Nanyo literature. An important clue to the analysis of 『Jawa·Baroe』 literature came from the question of whether all Indonesian intellectuals were cooperative with the Japanese military government as previous studies have shown. To answer these questions, this study first listed three aspects of Indonesian response of intellectuals to Japan's southward advancement: cooperation with the Japanese military government, somewhat critical, and indifference. The above three reactions to the southward march were repeated in the dual-word magazine 『Jawa·Baroe』. However, this study focused on works that could be used as counter examples to the logic that “Indonesia was cooperative for Japan,” which remained as hegemony of Indonesian research so far. As a result, it was clear that Indonesian intellectuals at that time wanted an independent Indonesia with their own cultural pride and nationalistic spirit, rather than being easily incorporated into the Greater East Asia Co-prosperity Sphere. In particular, the characteristics of Indonesian Japanese Nanyo literature as described above are more meaningful in that it has confirmed that Nanyo literature research is in a position where it can only be compared with other countries’ Nanyo literature.

고온기 온습도지수가 홀스타인종 젖소 착유우의 호흡수, 직장온도 및 반추활동 시간에 미치는 영향 연구

박지후,최희철,이현정,김언태,손준규,김동현 한국산학기술학회 2019 한국산학기술학회논문지 Vol.20 No.11

This study investigated the effects of environmental temperature and humidity on the physiological indicators such as respiratory rate, rectal temperature, and rumination time in cows. Twenty lactating Holstein cows were used for this study. The temperature/humidity index, which can be measured by the temperature and humidity of barns, was divided into three stages to distinguish the heat stress level of cows. The temperature and humidity indexes of each stage were classified into 70 ~ 75 for T1, 76 ~ 81 for T2, and 82 ~ 87 for T3, respectively. The respiratory rates per minute were 58.60 at T1, 66.12 at T2, and 84.05 at T3, respectively (P < 0.05), and the average rectal temperatures (℃) of the cows were 38.41 in T1, 38.69 in T2 and 39.05 in T3, respectively (P < 0.05). The body surface temperatures (℃) were 36.41 in T1, 36.51 in T2, and 37.39 in T3, respectively. The rumination times (minutes/day) were 473.10 in T1, 454.76 in T2, and 399.60 in T3, respectively (P < 0.05). As global warming continues to damage the dairy industry, further research is needed to improve the welfare of dairy cows and reduce their heat stress. 본 연구는 환경 온·습도가 젖소의 호흡수, 직장온도 등의 생리지표와 반추활동 시간에 미치는 영향을 알아보고자 수행되었다. 시험에 활용된 공시축은 홀스타인종 착유우 20두를 활용하였으며 젖소의 고온 스트레스 수준을 구분하기 위해 우사의 온도와 습도를 측정하여 환산된 온·습도지수(Temperature-Humidity Index)를 세 단계로 나누어 이용하였다. 각 단계별 온·습도지수는 1단계(T1)가 70~75, 2단계(T2)가 76~81, 3단계(T3)가 82~87로 구분되었다. 연구결과, 분당 호흡수(회/분)는 T1에서 58.60으로 나타났으며, T2에서는 66.12, T3에서 84.05로 나타났으며 시험축의 직장온도(℃)는 T1에서 38.41, T2에서 38.69, T3에서 39.05로 나타나 두 지표 모두 온·습도지수가 증가함에 따라 값이 유의하게 증가하였다(P < 0.05). 체표면 온도(℃)는 T1에서 36.41, T2에서 36.51, T3에서 37.39로 나타났으며 T1·T3 간 유의한 차이를 보였다(P < 0.05). 반추활동량(분/일)은 T1에서 473.10, T2에서 454.76, T3에서 399.60로 나타나 온·습도지수가 높아질수록 반추활동 시간은 감소하는 것을 확인하였다(P < 0.05). 최근 기후온난화로 인한 낙농산업의 피해가 지속될 것으로 전망됨에 따라 향후 젖소의 복지 증진과 고온 스트레스 감소 방안 마련을 위한 지속적인 연구가 필요할 것으로 보인다.

Social conflicts over local housing cooperative projects are also increasing as the number of businesses pushing for local housing cooperatives nationwide increases. The government is also aware of the seriousness of the problems of the local housing cooperative and is trying to protect its members by supplementing the law, but there is still a need to supplement the laws and systems regarding the local housing cooperative. Thus, in this paper, we wanted to study the characteristics of additional contributions through changes in the cost of local housing cooperative projects. In addition, the purpose of this research is to analyze cases of changes in project cost and additional contributions of local housing cooperative projects that are actually being carried out in the workplace, and to draw up problems related to the calculation of project cost and the change of additional contributions through expert awareness and to suggest improvement measures. In order to improve the problems caused by the change in the project cost of the local housing cooperative, 121 workplaces in 26 regions were generally analyzed through requests for information disclosure from 100 authorized and authorized public institutions nationwide. In addition, it is expected that the members" right to know, participation in the project and reliability will be improved in the process of promoting the local housing cooperative project through the recognition of various problems and system improvement derived from the expert group interviews and expert group discussions.

日本占領期インドネシアの二言語雑誌『ジャワ·バル』に掲載された 文学作品とその意味

박지후 ( Park Ji-hu ) 고려대학교 글로벌일본연구원 2023 일본연구 Vol.40 No.0

本研究は、日本占領期東南アジア(本稿では主にインドネシア)の文学作品研究が日本の観点から研究された、あるいは東南アジア研究の場で進められてきた限界から脱し、日本とインドネシアの関係性であることに注目し、インドネシア日本語南洋文学を新たに定義した上で、その基礎的資料にあたる『ジャワ·バル』を重点的に分析した。 『ジャワ·バル』の文学作品を分析する上で重要な端緒は、果たしてインドネシアの知識人は皆これまでの先行研究が明らかにしてきたように、日本軍政に協力的だったのかという問いである。このような問いに答えるため、本研究では、まず、インドネシアの知識人が日本の南進に反応した三つの様相―日本軍政に協力的な場合、多少批判的な場合、無関心な場合―を列挙し、その中で多少批判的な場合の反応はどのように展開されたかを確認した。 上記のような南進に関する三つの反応は、二言語雑誌『ジャワ·バル』にもそのまま繰り返されるものだった。ただし、本研究はこれまでのインドネシア研究のヘゲモニーとして残っていた「インドネシアは日本にとって協調的だった」という論理に反例として活用可能な作品を重点的に考察した。その結果、インドネシアの知識人たちが考えた当時の時代像は決して「大東亜共栄圏」に簡単に編入できるものではなく、彼らなりの文化的自負心と民族主義的精神で「独立した一つのインドネシア」を望んでいたことを明確にした。 特に、上記のようなインドネシア日本語南洋文学の特徴は、今後、南洋文学研究が日本中心主義から抜け出し、他国の南洋言説と相互比較されるしかない位置にあることを確認したという点で大きな意義を持つと言えるだろう。 This study focused on the relationship between Japan and Indonesia, which has been studied from a Japanese perspective or in Southeast Asian research, and analyzed the basic data 『Jawa·Baroe』 based on the new definition of Indonesian Japanese Nanyo literature.
