The horro movie which was released in 2003, was a box office hit drawing audiences totaling 3,140,000 people. Then, there were partial opinions that it was difficult to understand the content of the movie. However, it was most favorably received in the horror movies which were released before and after 2003. The 4 main characters in the movie are a family. The family conflicts begin as the dad has an affair. Muhyeon(the dad)'s infidelity leads his wife to kill herself. The suicide of the wife and mom again leads Suyeon(the younger sister) to be dead. At this moment, Suyeon's death is related to Eunju(the step mom). Sumi(the older sister) is deeply hurt by the fact that Eunju left her younger sister's death after she was dead. But at the same time, she realizes that she is also related to Eunju's act. And she felt guilty about her younger sister's death. Eunju was also hurt by Sumi's biting remarks. However, she feels guilty about the fact that she made Suyeon be dead. Director Jiun Kim said in the interview when it was released, "this movie is about hurts and guilt among families." These hurts and guilt are expressed by horror images that imagination and reality are mixed. Hurts are expressed by virtual images and guilt is done by real images. This paper presented still pictures which explain the virtual and real images and examined what hurts and guilt mean. And it described the symbolic meanings of three media which cause conflicts among main characters.

Eosinophilic pleural effusion (EPE) is defined as a pleural effusion that contains at least 10% eosinophils. EPE occurs due to a variety of causes such as blood or air in the pleural space, infection, malignancy, or an autoimmune disease. Undifferentiated connective tissue disease (UCTD) associated with eosinophilic pleural effusion is a rare condition generally characterized by the presence of the signs and symptoms but not fulfilling the existing classification criteria. We report a case involving a 67-year-old man with UCTD and EPE, who has been successfully treated with a single intrapleural corticosteroid injection.

The Arg-Gly-Asp (RGD) sequence serves as the primary recognition site in extracellular matrix proteins, and peptides containing this sequence can mimic the biological activities of matrix proteins. We have initiated structure-function studies of two RGD containing peptides, RGD-5(AGGDD) and cyclic RGD-6(CARGDDC). Assays have shown that cyclic RGD-peptides inhibit platelet aggregation more efficiently than linear ones. NMR data revealed that RGD-5 and RGD-6 have entirely different conformation. RGD-5 has a linear extended structure and RGD-6 has a stable loop conformation. In RGD-5 the guanidinium group of Arg2 and the carboxyl group of Asp4 lie in parallel, whereas the side-chains of Arg3 and Asp5 of RGD-6 are located in different planes, supporting the idea that the stability of the cyclic form derives from the packing of the side chain of the Arg and Asp residues. The structural features of these peptides could provide a basis for designing new drugs against diseases related to platelet aggregation and as cancer antagonists.

Tremor is a rhythmic, involuntary muscular contraction characterized by oscillations (to-and-fro movements) of a part of the body. Essential tremor is a 6-8 Hz tremor that is of variable amplitude. It is aggravated by posture and movement and relieved by rest and alcohol. Most affected part are the arms, head and vocal apparatus. The purpose of this study is to show a case of tremor patient with essential tremor improved by oriental medical treatment. The patient was 71-year-old woman who featured essential tremor and at the same time complained general body weakness, nausea, and anorexia. She was treated by oriental medicine with acupuncture, herb medication, and Korean psychotherapy; Eejeong-byunki, Jiun-goron. The features of essential tremor was reduced after taking oriental medical therapy. This result suggested that the oriental medical therapy can be effective for treating essential tremor.

It has been grown interests ot the convergence services about broadcasting and multicasting services such as Mobile IPTV. It needs the efficient scheduling and resource allocation algorithm because video contents have the large data. This paper proposes the resource allocation algorithm for the layered-encoded video coding in the multicasting services. Existing approaches only deal with the utility maximization in the current video frames. However, these algorithms have a problem for the Quality of Services(QoS) if the user's channel states are not good. We apply the delay constraint and find to maximize the utility values using the current content's frames and already assigned content's frames within the constraint periods. The performance of the proposed algorithm is evaluated by the higher layer transmission rates compared the existing algorithm and significantly improved for the QoS.

The main nutritional problem of sorghum${\times}$sudangrass hybrid (Sorghum bicolor${\times}$Sorghum sudanese) silage is low quality and palatability. This experiment was conducted to evaluate whether organic com grain and crushed rice addition of sorghum${\times}$sudangrass hybrid silage increases forage quality of the silage. The sorghum${\times}$sudangrass hybrid silages with added com grain and crushed rice were similar to conventional com silage in moisture content. However organic sorghum${\times}$sudangrass hybrid silage had low pH values. Silage added with gain and byproduct had higher crude ash, acid detergent fiber (ADF) and neutral detergent fiber (NDF) contents than control com silages, while its non-fiber carbohydrate (NFC) and total digestible nutrients (TDN) showed the opposite results. Lactic acid, butyric acid and lactic percentage of total organic acid (L/T) of sorghum${\times}$sudangrass hybrid silages were higher than those of com silage, but acetic acid was higher than control. In vitro dry matter digestibility (IVDMD) of com silage was higher than other sorghum silages. Feed intake of sorghum${\times}$sudangrass hybrid silage added with crushed rice was highest among silages. Therefore, these data indicate that crushed rice and com grain added sorghum${\times}$sudangrass hybrid silage could be recommended as the most effective treatment for increasing silage quality and palatability.

The rapidly growing metaverse environment has received widespread attention across various fields such as health and medicine, culture and gaming, as well as politics. However, the excessive collection of personal data by the diverse sensors and devices used in the metaverse environment poses a substantial threat to user privacy. In this paper, we investigate existing cases of secure Multi-Party Computation(MPC) applications, examine the services anticipated to be necessary for the expansion of the metaverse environment, and analyze the privacy issues present in the metaverse environment as well as the limitations of current real-world services. Based on these findings, we propose application scenarios that utilize MPC to preserve user privacy in the metaverse environment. These proposed MPC application scenarios present a new perspective in metaverse security research. In the future, they are expected to be utilized in the development of secure metaverse services.

Objective: The purpose of this study was to further the empirical evidence regarding exercise as an effective alternative to surgery for treating patients with low to moderate hallux valgus. Method: A total of 20 students with low to moderate hallux valgus participated in this study for six weeks. Participants were selected according to foot-print. All participants exercised using a combination of Elastic-band and Short Foot Exercises twice a week for thirty minutes each time. Measurements were taken at week 0 and week 6 for plantar foot pressure, toe angle and balance. The data was processed using a paird t-test. Results: There were significant differences in pretest and posttest measurements for balance. However there were no significants differences in plantar foot pressure and toe angle. Conclusion: Although our study did not support the effect of exercises on plantar foot pressure and toe angle, we did show evidence that exercise was effective for balance. In order to increase the effectiveness of this exercise program, patients need to be more aware of the footwear they use in their daily lives so as to contribute to the contribute to the overall effectiveness of treating low to moderate hallux valgus and offer an alternative to surgery.

This study delves into a question as to how the concept of corporate social responsibility (CSR) is internalized across corporations. CSR internalization refers to the process where a corporation incorporates CSR practices into its business practices. Drawn from the institutionalization process of knowledge adoption under environmental pressure, we pay attention to the roles of proximity, defined as the distance between environmental characteristics and organizational characteristics of corporations. And we argue that the extent to which a given firm is situated in the environment knowledgeable will make the firm likely to adopt CSR practices. To test this idea, we figure out when and how corporations participate in the B-Corporation Movement in the U.S., through the lens of proximity. Specifically, we subdivide proximity into geographical proximity, organizational proximity, and overlapped proximity and examine whether proximity can increase the likelihood of adopting CSR practices. With a sample of 536 start-ups which had participated in the B-Corporation Movement between 2007 and 2017, we find that the three types of proximity consistently increase the likelihood of becoming a certified B-Corp. This suggests that a corporation is highly likely to accept the concept of CSR under external pressures, along with its intrinsic motivation, which provide theoretical and practical implications on CSR internalization.
