This study aims to find whether there is a difference between the resulting responsiveness and substantial responsiveness, as noticing citizen satisfaction of the result of information disclosure is not equivalent to a high rate of information disclosure. Previous studies focused on the analysis of the resulting responsiveness such as disclosure decision and processing time. However, this study would identify how much opened information is equal to requested information on the side of substantial responsiveness. This study found that accuracy dropped as opening not requested information but different information and completeness dropped as omitting some part of information or opening unseizable information on the side of substantial responsiveness. There are differences between the resulting responsiveness and substantial responsiveness. Some of the opened information is not requested information despite the disclosure decision. It takes over ten days despite the immediately disclose decision. The main reason for the decline in substantial responsiveness is the passing of document retention period and the absence of data. Therefore, the obligation for the creation and preservation of records for public agencies will have to be followed with the agencies' will to opening information. Although this study analyzes the limited cases, it is significant to enunciate there are differences between the resulting responsiveness and substantial responsiveness.

The purpose of this study is to investigate the relationship between the service quality of WPL (Work Place Learning) and the revisit intention through customer satisfaction, targeting users who use the WPL. Data to achieve the purpose of this study were conducted for trainees who had received on-the-job training at 4 selected WPL in Jeollabuk-do. Out of the 210 copies of questionnaires, 170 were picked up, and all of them were used for analysis. As a result of the analysis, First, as a result of analyzing the relationship between service quality and customer satisfaction in WPL, it was discovered that among the service quality components, Responsiveness, Assurance, and Empathy had a substantial influence on customer satisfaction, while Tangibles and Reliability of service quality did not appear to have any significant effect. Second, it was discovered that customer contentment had a considerable influence on revisit intention after evaluating the link between customer satisfaction and revisit intention. It can be shown that the higher the level of client happiness, the greater the likelihood of returning. Third, as a result of analyzing the relationship between service quality and revisit intention of WPL, among service quality factors, Reliability, Responsiveness, and Empathy were found to have a significant effect on revisit intention. As a result of verifying the mediating effect of service quality at WPL on revisit intention through customer satisfaction, responsiveness, assurance, and empathy of service quality were found to be significant in their relationship with revisit intention.

The immature neonatal brain is susceptible to the development of seizures. Seizures occur in 1% to 5% of infants during the neonatal period. Neonatal seizures are most commonly associated with serious acute illnesses, such as hypoxic-ischemic encephalopathy, birth trauma, metabolic disturbances, or infections. Thus, newborn infants with seizures are at risk for neonatal death and survivors are at risk for neurologic impairment, developmental delay, and subsequent epilepsy. Experimental data have also raised concerns about the potential adverse effects of the currently used anticonvulsants in neonates on brain development. Therefore, in the management of neonatal seizures, confirmatory diagnosis and optimal, but shorter, duration of anticonvulsant therapy is essential. Nevertheless, there has been substantial progress in understanding the developmental mechanisms that influence seizure generation and responsiveness to anticonvulsants. The currently used therapies have limited efficacy and the treatment of neonatal seizures has not significantly changed in the past several decades, This review includes an overview of current approaches to the treatment of neonatal seizures.

The interactions between B7 molecules and CD28-family receptors are crucial in the regulation of adaptive cellular immunity. In cancer, the aberrant expression of co-inhibitory B7 molecules has been attributed to reduced anti-tumor immunity and cancer immune evasion, prompting the development of cancer therapeutics that can restore T cell function. Murine tumor models have provided significant support for the targeting of multiple immune checkpoints involving CTLA-4, PD-1, ICOS, B7-H3 and B7-H4 during tumor growth, and clinical studies investigating the therapeutic effects of CTLA-4 and PD-1 blockade have shown exceptionally promising results in patients with advanced melanoma and other cancers. The expression pattern of co-inhibitory B7 ligands in the tumor microenvironment has also been largely correlated with poor patient prognosis, and recent evidence suggests that the presence of several B7 molecules may predict the responsiveness of immunotherapies that rely on pre-existing tumor-associated immune responses. While monotherapies blocking T cell co-inhibition have beneficial effects in reducing tumor burden, combinatorial immunotherapy targeting multiple immune checkpoints involved in various stages of the anti-tumor response has led to the most substantial impact on tumor reduction. In this review, we will examine the contributions of B7- and CD28-family members in the context of cancer development, and discuss the implications of current human findings in cancer immunotherapy.

Innate lymphoid cells (ILCs) are critical immune-response mediators. Although they largely reside in mucosal tissues, the kidney also bears substantial numbers. Nevertheless, kidney ILC biology is poorly understood. BALB/c and C57BL/6 mice are known to display type-2 and type-1 skewed immune responses, respectively, but it is unclear whether this extends to ILCs. We show here that indeed, BALB/c mice have higher total ILCs in the kidney than C57BL/6 mice. This difference was particularly pronounced for ILC2s. We then showed that three factors contributed to the higher ILC2s in the BALB/c kidney. First, BALB/c mice demonstrated higher numbers of ILC precursors in the bone marrow. Second, transcriptome analysis showed that compared to C57BL/6 kidneys, the BALB/c kidneys associated with significantly higher IL-2 responses. Quantitative RT-PCR also showed that compared to C57BL/6 kidneys, the BALB/c kidneys expressed higher levels of IL-2 and other cytokines known to promote ILC2 proliferation and/or survival (IL-7, IL-33, and thymic stromal lymphopoietin). Third, the BALB/c kidney ILC2s may be more sensitive to the environmental signals than C57BL/6 kidney ILC2s since they expressed their transcription factor GATA3 and the IL-2, IL-7, and IL-25 receptors at higher levels. Indeed, they also demonstrated greater responsiveness to IL-2 than C57BL/6 kidney ILC2s, as shown by their greater STAT5 phosphorylation levels after culture with IL-2. Thus, this study demonstrates previously unknown properties of kidney ILC2s. It also shows the impact of mouse strain background on ILC2 behavior, which should be considered when conducting research on immune diseases with experimental mouse models.

Thallium-201 $(^{201}T1)$ SPECT studies were performed on a normal volunteer and 12 patients with intracerebral lesions: 3 patients with gliomas, 3 patients with meningiomas, 1 patient each with metastatic tumor, brain abscess, and cerebral infarction, and 3 postirradiation patients. (2 with metastatic tumors, 1 with lymphoma). A $^{201}T1$ index, based on the ratio of $^{201}T1$ uptake in the brain lesion versus the homologous contralateral brain, was calculated and compared with tumor histology and CT/MRI findings. The SPECT $^{201}T1$ scan showed minimal uptake of tracer in a normal brain. There was substantial uptake of $^{201}T1$ in high-grade gliomas (index>1.5) with little uptake in low-grade lesions. A previously irradiated patient with recurrent astrocytoma, in whom MRI study was unable to distinguish tumor recurrence from necrosis, showed the lesions with high $^{201}T1$ indices in both hemispheric regions (2.50/1.93), suggesting tumor recurrence. Two meningiomas and a metastatic tumor showed varying degrees of $^{201}T1$ uptake (index $1.71\sim8.15$), revealing that $^{201}T1$ uptake is not exclusive to high-grade gliomas. In 2 postirradiation patients with metastatic tumors, no abnormal $^{201}T1$ uptake was found in the cerebral lesions, shortly after the initiation of radiation therapy or despite the persistence of enhancing lesions-though improved-on MR images, suggesting that $^{201}T1$ uptake may reflect the metabolic and possibly clonogenic activities of tumors and the brain $^{201}T1$ SPECT imaging might be valuable for the evaluation of tumor responsiveness to the therapy and for early detection of tumor recurrence. A patient with brain abscess on antibiotic treatment, showig increased uptake of $^{201}T1$ in the resolving lesions (index 2.87/1.52) is discussed. In a patient with cerebral infarction, there was no abnormal uptake of $^{201}T1$ in infarcted tissue. When using a threshold index of 1.5, correlation rate between $^{201}T1$ uptake and contrast enhancement of the cerebral lesions on CT/MRI was 73% (8/11). In conclusion, the brain $^{201}T1$ SPECT imaging may be useful for assessment of tumor response to the therapy and to predict low-or high-grade lesions.

Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation that is usually progressive. It is a major cause of morbidity and mortality worldwide, leading to substantial and increasing economic and social burden. Palliative care for COPD patients aims to reduce symptoms and exacerbations and improve exercise tolerance and quality of life. It is difficult to make a prognosis for COPD patients due to the variable illness trajectory and advanced care of patients. However, severity of breathlessness, assessment of lung function impairment, and frequency of exacerbations can help to identify palliative care needs and determine effective methods to mitigate symptoms, which is discussed in this paper. In these patients, it is recommended to provide individualized palliative care along with curative/restorative care at the onset of COPD symptoms. Before launching a palliative care system in Korea, it is necessary to prepare pulmonary rehabilitation resources, patient-centered communication, timely palliative responsiveness, and a program for effective advanced care planning. A multidisciplinary approach involving collaboration with not only the respiratory and palliative care teams but also primary care offers a new model of care for these patients and should be considered with a priority.

Race and ethnicity are important factors which influence the elderIy's residential adjustment behaviors, although it is unclear whether this reflects influences unrelated to race and ethnlcity. Culturally, the norm of family supportoften obseved among various minority ethnic groups is likely to provide flexible family suppof for the elderIy. Economically, the life-long hardship ofminority groups is likely to force them to maintain extended family living arrangements simply to reduce expenses via economies of scale. Thecontroversy about the economic need versus the cultural prescription forextended living arrangements remains unresoIved because it fails to articulatethe meaning of family supports among many disadvantaged groups.This study aims to test previous economic and cultural arguments, byexamining ethnic differences iu the eiderIy's responsiveness to their health andeconomic problems. Two hypotheses about cultural influences on the elderly's resideutiai adjustment are examined. First, do elderly minorities receive famiiysupporis for longer periods when they are poor if economic and health status\ulcorner Second, do elderiy minorities receive family supports more often when their health status declines\ulcorner Using the Longitudinal Suvey on Aging from 1984 to 1990. this study employs Markovian multi-state life tables, and discrete and contonuous competing hazard analyses for the transition in living arrangements. The main results provide substantial evidence against the cultural resource thesis. Elderly minorities experience more frequent transition between living alone and living with relatives than white elderly persons when group differences in the extent of mortality and insititutionalization are controlled. The shorter timf of living alone among elderly monorities stems from their greater likehood of joining relatives as well as greater mortality and attrition rates than elderly whites. Coresidence of elderly whites with their relatives is more likely to occur in response to their needs for health care than of elderly whites. it implies that instability. not flezibility. characterrizes elderly minorities living arrangements.
