Death has been one of the basic objects in philosophy and religion. Why do people feel afraid about death? Maybe it is because they don't know the situation after death or because they have a wrong idea about it. Someone may think that he/she doesn't care the situation. But this attitude is wrong. We must understand that our attitude about life is shaped by our knowledge of the situation after death. A recurrent theme about death in popular thought is the idea that death is mysterious. As we have seen, it is difficult to formulate a satisfactory philosophical analysis of the concept of death. If it is impossible to analyse the concept of death, then it is impossible to explain precisely what we mean when we say that something dies. It might be said therefore that, in virtue of this fact, death is mysterious. Of course, death is not distinctively mysterious - all other unanalysable concepts are equally mysterious in this way. Reflection on death gives rise to a variety of philosophical questions. One of the deepest of these is a question about the nature of death. Typically, philosophers interpret this question as a call for an analysis or definition of the concept of death. Plato, for example, proposed to define death as the separation of soul from body. However, this definition is not acceptable to those who think that there are no souls. It is also unacceptable to anyone who thinks that plants and lower animals have no souls, but can nonetheless die. Others have defined death simply as the cessation of life. This too is problematic, since an organism that goes into suspended animation ceases to live, but may not actually die. The eastern philosophers proposed to define death as the nonduality of life and death. Taoists, for example, do not believe in the Wheel of Life of the Buddhists nor in the Heaven or Hell of Christianity. Taoists view existence as glorious. The whole Universe, they teach, is a marvelous, vibrant Unity wherein everything, visible and invisible, pulses with energy and changes. As being develops through the experience of existence, its vessels are swept onwards by the mighty stream of the eternal TAO to other forms of expression and activity. Man does not die; he merely extends into new fields. Taoists teach that the end of a person is the return to the Ultimate Reality. "Life is uncertain - Death is certain": This is a well known saying in Buddhism. Knowing very well that death is certain and it is a natural phenomenon that everyone has to face, we should not be afraid of death. Yet, instinctively, all of us fear death because we do not know how to think of its inevitability. We like to cling to our life and body and so develop too much craving and attachment.

A 42-year-old female was referred to our department after find out submucosal tumor type lesion on cardia at local clinics. She experienced no specific symptom. On gastroscopy, two distinct neoplasms were detected. One of which was located in the cardia anterior wall of the stomach with the size of 2.0×1.1 cm, and the other one was localized in the cardia posterior wall of the stomach and its size was 1.5×1.2 cm. We performed endoscopic submucosal dissection. Pathological evaluation revealed the diagnosis of gastrointestinal stromal tumor (GIST) at the cardia anterior wall and malignant lymphoma from the mass localized cardia posterior wall of the stomach. We would like to report these rare synchronous tumors which were successfully treated by endoscopic resection in the same patient

With the development of information and communication technology, the amount of information produced and shared in the battlefield and stored and managed in the system dramatically increased. This means that the amount of information which cansupport situational awareness and decision making of the commanders has increased, but on the other hand, it is also a factor that hinders rapid decision making by increasing the information overload on the commanders. To overcome this limitation, this study proposes a method to automatically search, select, and summarize documents that can help the commanders to understand the battlefield situation reports that he or she received. First, named entities are discovered from the battlefield situation report using a named entity recognition method. Second, the documents related to each named entity are discovered. Third, a language model and collaborative filtering are used to select the documents. At this time, the language model is used to calculate the similarity between the received report and the discovered documents, and collaborative filtering is used to reflect the commander's document reading history. Finally, sentences containing each named entity are selected from the documents and sorted. The experiment was carried out using academic papers since their characteristics are similar to military documents, and the validity of the proposed method was verified.

This study was conducted to explore how men's and women's self-construals do change according to gender-stereotype activation. The results showed that men have stronger gender-stereotypes and construe self more gender-stereotypic way than women. In general, women showed having less gender-stereotype but they construed self more stereotypic way. And the stereotype activation affected only on women to construe self less stereotypic way. Both men and women do accept physical appearance stereotypes more than other domains of gender-stereotype when they construe their selves. Gender-role stereotypes are more accepted by men than women, and gender-stereotypes of ability are more accepted by men but refused by women when stereotype was activated. And men accepted prescriptive gender-stereotype more than women. People of high gender-stereotype group construe self more stereotypic way than those of low stereotype group. But in low gender-stereotype group, women construe self less stereotypic way when stereotype is activated than when not. These results are taken to show, among others, that self-stereotyping of targets were different depending on whether the targets are man or woman, and that self stereotyping of an individual contributes to build a mechanism of maintaining gender-stereotype of a society to which he or she belongs.

Objective: This study attempts to increase awareness of hepatotoxicity caused by antipsychotic drugs and to provide updated information on drug-induced liver injury (DILI) to physicians in Korean medicine (KM) clinics. Methods: This study presents a detailed case of a female patient diagnosed with DILI attributed to antipsychotic drugs, highlighting the improvement observed through laboratory findings. Results: A 56-year-old female patient with underlying disorders, including mixed connective tissue disease and depression, was under medical care. One day, she reported experiencing intense fatigue and distressing sensations, prompting the author to order blood tests. The levels of AST and ALT were significantly elevated by more than 2.5-fold, indicating hepatocellular DILI. The RUCAM score for antipsychotic drugs was 9, as no other medications, including herbal medicine, were being taken. Upon discontinuation of the antipsychotic drugs, the patient's laboratory findings returned to normal levels within 2 weeks, accompanied by a recovery of subjective symptoms. Conclusion: This study presents a noteworthy case of hepatotoxicity caused by antipsychotic drugs, serving as an illustrative example that highlights the crucial need for awareness among doctors of KM in clinical settings.

Objective: To investigate the association between CT imaging features and survival outcomes in patients with primary invasive mucinous adenocarcinoma (IMA). Materials and Methods: Preoperative CT image findings were consecutively evaluated in 317 patients with resected IMA from January 2011 to December 2015. The association between CT features and long-term survival were assessed by univariate analysis. The independent prognostic factors were identified by the multivariate Cox regression analyses. The survival comparison of IMA patients was investigated using the Kaplan-Meier method and propensity scores. Furthermore, the prognostic impact of CT features was assessed based on different imaging subtypes, and the results were adjusted using the Bonferroni method. Results: The median follow-up time was 52.8 months; the 5-year disease-free survival (DFS) and overall survival rates of resected IMAs were 68.5% and 77.6%, respectively. The univariate analyses of all IMA patients demonstrated that 15 CT imaging features, in addition to the clinicopathologic characteristics, significantly correlated with the recurrence or death of IMA patients. The multivariable analysis revealed that five of them, including imaging subtype (p = 0.002), spiculation (p < 0.001), tumor density (p = 0.008), air bronchogram (p < 0.001), emphysema (p < 0.001), and location (p = 0.029) were independent prognostic factors. The subgroup analysis demonstrated that pneumonic-type IMA had a significantly worse prognosis than solitary-type IMA. Moreover, for solitary-type IMAs, the most independent CT imaging biomarkers were air bronchogram and emphysema with an adjusted p value less than 0.05; for pneumonic-type IMA, the tumors with mixed consolidation and ground-glass opacity were associated with a longer DFS (adjusted p = 0.012). Conclusion: CT imaging features characteristic of IMA may provide prognostic information and individual risk assessment in addition to the recognized clinical predictors.

The purpose of this study is to understand how a teacher's teaching can be changed while he or she teaches the same contents in different classes. The qualitative research method was used in this study. Data were collected from classroom observations, several in-depth interviews, and stimulated-recall interviews after each class. All the data were transcribed and analyzed interpretively, and then, the results of the analysis were checked by each participating teacher. The results are as follows: First, changes appeared in each class in terms of the teaching items, tools, sequence, and time, even though the same teacher taught the same contents. It showed that the teacher's teaching practice changed immediately and intuitively in class. Second, teachers tried to implement "exploratory teaching" or "move-testing teaching" to address the emerging problems during their teaching. They then reflected on and modified their own teaching. This type of change, which happened during the teaching practice, can be an example of "Reflection-in-practice." Thus, the results of this study can provide helpful insights into how teachers might adapt and reflect in their teaching. It suggests that teachers need to recognize their subconscious teaching changes and learn "Reflection-in-practice."

Recently, there have been studies about Typically- Perceived-Situations (TPSs) and about critical examples as a way to understand students' preconceptions with context. TPS is a situation arising immediately in one's mind when he or she thinks about the concept, while a critical example is an example that becomes the most helpful in learning the concept. We might explore how the context is involved in the process of students' conceptual understanding by examining TPSs and critical examples together. This study analyzed, through questionnaires and interviews, the characteristics of TPSs and those of critical examples that secondary students hold about 'force' and 'mechanical energy conversion.' Students' TPSs and critical examples showed different characteristics according to the concept. In a case of force that is related to everyday life, there were various situations as TPSs and critical examples. Unlike force, there were a few situations as TPSs and critical examples such as a falling ball in the case of mechanical energy conversion. Students tended to regard situations that are usually experienced and understood easily as TPSs or critical examples. On the basis of the results of this study, it is concluded that it would be a good strategy to teach science concepts for teachers to start with the TPS of a concept, to introduce the concept, and then to expose the attributes of the concept with critical examples.

This study investigated how birth weight differences in piglets affected carcass and muscle fiber properties as well as meat quality at slaughter. Within litters, piglets were grouped according to their birth weight as either normal (NBW; 1.62-1.73 kg) or low (LBW; 1.18-1.29 kg). At 5 weeks of age, NBW piglets were randomly transitioned to control (C) or isocaloric high fat diets derived from non-dairy (HF), while LBW piglets were randomly transitioned to high fat diets derived from non-dairy (HF) or dairy sources (HFHD). Piglets were reared in individual pens under standardized housing and feeding conditions. Live weight was recorded weekly, and pigs were slaughtered at 12 weeks of age. Hot carcass weights, dressing percentages, lean meat yield, and primal cut proportions were determined. The m. longissimus thoracis was collected from the right side of the carcass for measurement of physical and chemical properties of meat and muscle fiber characteristics. Results indicated that LBW pigs compensated for their live weight compared to NBW pigs at 6 weeks of age. The mean muscle fiber diameter of LBW-HFHD group is significantly higher than NBW-C and NBW-HF group, and the type I muscle fiber diameter is significantly higher than NBW-C group. Dairy fat inclusion in LBW pig diet reduced carcass back fat thickness. This increased the calculated lean meat yield to be comparable to that of NBW pigs fed a commercial diet. Incorporating dairy-sourced high-fat into LBW pigs' diets appears to be an effective strategy for producing carcasses equivalent to NBW pigs.

Attenuated portal vein (PV) flow is challenging in pediatric liver transplantation (LT) because it is unsuitable for classic end-to-end jump graft reconstruction from a small superior mesenteric vein (SMV). We thus introduce a novel technique of an end-to-side jump graft from SMV during pediatric LT using an adult partial liver graft. We successfully performed two cases of end-to-side retropancreatic jump graft using an iliac vein graft for PV reconstruction. One patient was a 2-year-old boy with hepatoblastoma and a Yerdel grade 3 PV thrombosis who underwent split LT. Another patient was an 8-month-old girl who had biliary atresia and PV hypoplasia with stenosis on the confluence level of the SMV; she underwent retransplantation because of graft failure related to PV thrombosis. After native PV was resected at the SMV confluence level, an end-to-side reconstruction was done from the proximal SMV to an interposition iliac vein. The interposition vein graft through posterior to the pancreas was obliquely anastomosed to the graft PV. There was no PV related complication during the follow-up period. Using a jump vascular graft in an end-to-side manner to connect the small native SMV and the large graft PV is a feasible treatment option in pediatric recipients with inadequate portal flow due to thrombosis or hypoplasia of the PV.
