  • Narrative activities are closely related to the space where human beings live and their awareness of space. In the film Parasite (2019), Director Bong Joon-ho demonstrated his unique insights into the spatial layout of the city. He not only built opposing up and down spaces with clear differentiation of distinct classes, but also conducted complex and smooth narratives in space. Bong Joon-ho used realism to express differences and some unresolvable contradictions between the classes in capitalist society by showing the daily lives of people living in different spaces. This present research focuses on Bong Joon-ho's spatial narrative in the film Parasite, hoping to observe the relationship between characters and between social classes, further exploring Director Bong Joon-ho's spatial narrative awareness and his film creation style. The research reveals that space, an important element of film narrative, has been paid attention to in the film Parasite and space is the narrative's foundation in this film. The narrative of film space is not limited to physical space but also refers to the relationship between characters and the society in which they live, showing metaphorical significance. This film transcends a genre film, portraying the changes of social classes in the development of the society. The film as a whole is one combining ideology and artistry. Every viewer can feel resonated from this film and understand the thought-provoking social situation.

  • The intracellular parasite Babesia microti is among the most significant species causing human babesiosis and is an emerging threat to human health worldwide. Unravelling the pathogenic molecular mechanisms of babesiosis is crucial in developing new diagnostic and preventive methods. This study assessed how priming with B. microti surface antigen 1 (BHSA 1) and seroreactive antigen 5-1-1 (BHSA 5-1-1) mediate protection against B. microti infection. The results showed that 500 ㎍/ml rBMSA1 and rBMSA5-1-1 partially inhibited the invasion of B. microti in vitro by 42.0±3.0%, and 48.0±2.1%, respectively. Blood smears revealed that peak infection at 7 days post-infection (dpi) was 19.6%, 24.7%, and 46.7% in the rBMSA1, rBmSA5-1-1, compared to the control groups (healthy mice infected with B. microti only), respectively. Routine blood tests showed higher white blood cell, red blood cell counts, and haemoglobin levels in the 2 groups (BMSA1 and BMSA5 5-1-1) than in the infection control group at 0-28 dpi. Moreover, the 2 groups had higher serum interferon-γ, tumor necrosis factor-α and Interleukin-17A levels, and lower IL-10 levels than the infection control group throughout the study. These 2 potential vaccine candidate proteins partially inhibit in vitro and in vivo B. microti infection and enhance host immunological response against B. microti infection.

Investigation on the Cause of Bad Natural Seed Collection of the Pacific Oyster, Crassostrea gigas: Relationships between the Conditions of Mother Shell and the Viability of the Released Eggs and Larvae Based on the Pathological and Embryological Survey (참굴 채묘 부진 원인 구명에 관한 연구 -병리 발생학적 조사를 통한 참굴 모패의 건강도와 난 및 유생의 생존율과의 상관관계 구명 -)

  • Infection rates of oyster ovarian parasite, Marteiliodes chungmuensis and productivity of the oyster shellstock infected with the parasite were investigated at the main seed collection areas in the southern coast of Korea where the extreme bad seed collection of oyster occurred in 1992 and 1993 to evaluate the cause of the bad seed collection. Additionally, the bacterial flora of the sea water and oyster lana were examined to identify the shellfish larva pathogenic bacteria like Vibrio sp. and Pseueomonas sp. In August 1992 to September 1993, infection rate of oyster ovarian parasite, M. chungmuensis at Tongyong, Kyongsangnam province, and Yosu, Chollanam province where the bad seed collection occurred, were $11.8\~100\%$ and $14.3\~100\%$, respectively. But the parasite was not detected in the shellstock collected at Daechon, Chungchongnam province. While a virus-like particle was identified in the cytoplasm of the egg infected by the parasite. The parasite infected egg was not able to fertilize completely. Uninfected egg in the gonad contaminated by the parasite could be able to fertilize but showed an abnormal development till D-shaped larva and then, died of necrosis after D-shaped lana. And some lana developed from low lipid content egg could not develop to the spat and died after the early umbo stage. The predominant bacteria in the oyster lana collected at bad seed collection areas were Pseudomonas sp. and Pseudomonas like bacteria and the occupancy rates were $53.3\~87.1\%$.

  • Infections involving Echinostoma hortense (E. hortense) are considered to more severe than infections caused by other heterophyids. Although parasite expulsion by host immune responses attenuates the symptoms of infection, the detailed mechanisms of the host immune response need to be determined, especially in local immune responses involving cytokine and immunoglobulin expressions. We infected BALB/c mice with E. hortense and examined recovery rates together with expressions of multiple cytokines and immunoglobulins in the villi and crypts of the small intestine using immunohistochemistry. We observed a close correlation between worm expulsion rates and cytokine/immunoglobulin expressions in E. hortense infected mice. This study contributes to an understanding of the relationship between the immune response and parasite expulsion in hosts.

  • This report was undertaken to examine the correlationship between internal parasite infection and amount of milk production before and after vermicidal administration on F. hepatica and gastrointestinal nematoda infected cattle. The obtained results were as follows ; 1. Out of total number(358), the ratios of parasitic infected catle were 43.5%(156). Among them milking cattl. and Korean native cattle were 52.7% and 31.6%, respectively. 2. In this examination, 10 kinds of parasites were detected. Among them F. hepatica was encountered most frquently and also Buxtonella, Paramphistoma, Coccidim, Cestoda, and Trichur were encountered in order. 3. The average increased amount of milk production after vermicidal administration on F. hepatica and gastrointestinal nematoda infected cattle was 1.1Kg per day.
