In the era of the fourth industrial revolution technology, the inclusion of personalized nutrition for healthcare (PNH), when establishing a healthcare platform to prevent chronic diseases such as obesity, diabetes, cerebrovascular and cardiovascular disease, pulmonary disease, and inflammatory diseases, enhances the national competitiveness of global healthcare markets. Furthermore, since the government experienced COVID-19 and the population dead cross in 2020, as well as numerous health problems due to an increasing super-aged Korean society, there is an urgent need to secure, develop, and utilize PNH-related technologies. Three conditions are essential for the development of PNH technologies. These include the establishment of causality between obesity genome (genotype) and prevalence (phenotype) in Koreans, validation of clinical intervention research, and securing PNH-utilization technology (i.e., algorithm development, artificial intelligence-based platform, direct-to-customer [DTC]-based PNH, etc.). Therefore, a national control tower is required to establish appropriate PNH infrastructure (basic and clinical research, cultivation of PNH-related experts, etc.). The post-corona era will be aggressive in sharing data knowledge and developing related technologies, and Korea needs to actively participate in the large-scale global healthcare markets. This review provides the importance of scientific evidence based on a huge dataset, which is the primary prerequisite for the DTC obesity gene-based PNH technologies to be competitive in the healthcare market. Furthermore, based on comparing domestic and internationally approved DTC obese genes and the current status of Korean obesity genome-based PNH research, we intend to provide a direction to PNH planners (individuals and industries) for establishing scientific PNH guidelines for the prevention of obesity.

This study was conducted to evaluate effect of plants number per hill (PNH) on growth and yield of sorghum in drained paddy field for 2 years. Crop growth and development and yield in the field was examined to know the efficiency of proposed cropping system. At seeding after 40 days, leaf number and stem diameter were highest at 1 PNH plot, on the other hands, plant height was at 5 PNH plot the $1^{st}$ and $2^{nd}$, respectively. The harvest stage, 5 PNH plot was highest culm length of 183, 188 cm the $1^{st}$ and $2^{nd}$, however, culm diameter was lowest. Culm length of sorghum was highest by 183, 188 cm at 5 PNH plot also, culm diameter was thickest by 19.18, 20.13 mm at 1 PNH, respectively. Yield components of ear length, seed number per ear and 1000-seed weight were highest at 1 PNH the $1^{st}$ and $2^{nd}$, respectively. As yield of sorghum was highest at 2 PNH plot $344kg{\cdot}10a^{-1}$, $382kg{\cdot}10a^{-1}$ yearly, respectively that it were in order of 1 PNH plot > 3 PNH plot > 4 PNH plot > 5 PNH plot.

Paroxysmal nocturnal hemoglobinuria(PNH) is an acquired hematologic disorder characterized by intravascular hemolysis, nocturnal hemoglobinuria, thrombotic events and bone marrow failure. It rarely occurs in children and can be complicated by acute renal failure(ARF). Here, we present two cases of ARF complicating PNH which has not been reported yet in Korean children. We suggest that PNH should be considered in differential diagnosis of ARF in children associated with intravascular hemolysis.

The human folate receptor (hFR) is a glycosylphosphatidylinositol (GPI) linked plasma membrane protein that mediates delivery of folates into cells. We studied the sorting of the hFR using transfection of the hFR cDNA into MDCK cells. MDCK cells are polarized epithelial cells that preferentially sort GPI-linked proteins to their apical membrane. Unlike other GPI-tailed proteins, we found that in MDCK cells, hFR is functional on both the apical and basolateral surfaces. We verified that the same hFR cDNA that transfected into CHO cells produces the hFR protein that is GPI-linked. We also measured the hFR expression on the plasma membrane of type III paroxysmal nocturnal hemoglobinuria (PNH) human erythrocytes. PNH is a disease that is characterized by the inability of cells to express membrane proteins requiring a GPI anchor. Despite this defect, and different from other GPI-tailed proteins, we found similar levels of hFR in normal and type III PNH human erythrocytes. The results suggest the hypothesis that there may be multiple mechanisms for targeting hFR to the plasma membrane.

Periventricular nodular heterotopia (PNH) is a malformation of cortical development in which normal neurons inappropriately cluster in periventricular areas. Patients with Mowat-Wilson syndrome (MWS) typically present with facial gestalt, complex neurologic problems (e.g., severe developmental delay with marked speech impairment and epilepsy), and multiple anomalies (e.g., Hirschsprung disease, urogenital anomalies, congenital heart defects, eye anomalies, and agenesis of the corpus callosum [CC]). MWS is mostly caused by haploinsufficiency of the gene encoding zinc-finger E-box-binding homeobox 2 (ZEB2) due to premature stops or large deletions. We present a case report of a 9-year-old girl with PNH, drug-responsive epilepsy, severe intellectual disability, and facial dysmorphisms only in whom we performed whole-exome sequencing and found a de novo heterozygous missense mutation (c.3134A>C; p.His1045Pro) of ZEB2 (NM_014795.3; NP_055610.1). This mild case of MWS caused by a rare novel missense mutation of ZEB2 represents the first report of MWS with isolated PNH.

Paroxysmal nocturnal hemoglobinuria (PNH) is an uncommon hematologic disease characterized by an abnormal sensitivity of blood cells to the lytic action of serum complement. We experienced one case of PNH in Yeungnam University Hospital from May 1983 to May 1989. The patients was followed up without severe complications for 4 years since diagnosis with the only consevating treatments such as washed blood transfusion, adrenal corticosteroids, androgens, folate and iron preparation, intermittently.

Several new palladium(II) complexes of aminophosphines, $(Pd(L)X_2)$, (L = $Ph_2PNH$ ++ $NR_2$; R = $CH_3(L_1)$, $C_2H_5(L_2)$ : X = Cl, Br, I, and NCS) that contain two different donor atoms of nitrogen and phosphorus as ${\pi}$-electron acceptor, were synthesized and characterized by conductivity measurement, ir, and UV/Vis-spectra. For the dithiocyanatopalladium(II) complexes with aminophosphines, it was confirmed that the thiocyanate group trans to phosphorus is coordinated as Pd-NCS mode and the one trans to nitrogen as Pd-SCN mode, and the aminophosphines form six-membered chelate ring. The spectra of dihalogenopalladium(II) complexes with aminophosphines show that the band maxima are shifted to the short wavelengths as the concentration is decreased.

Herpes zoster (HZ) is the secondary manifestation of an earlier infection with the varicella-zoster virus in one or more dermatomes. As reactivation of the virus is linked to an age-related diminished virus-specific and cell-mediated immunity, HZ develops mainly in elderly people. Acute zoster is painful, but does not incur lasting morbidity. Reactivation of the varicella-zoster virus in the trigeminal nerve (Herpes zoster) occur with severe pain and rash in the oro-facial region. The acute pain decreases as the rash begins to heal. Postherpetic neuralgia(PHN), the most frequent complication of herpes zoster, is usually defined as pain in the involved dermatome that is still present 3 month after rash onset. The clinical characteristics of PHN are, eposodic stabbing pain, burning pain and allodynia, with hypoesthesia and/or dysesthesia. $Neurometer^{(R)}$(neuroselective sensory nerve conduction threshold: sNCT, Automated current perception threshold: CPT, neurotron incorporated. Baltimore, Maryland. 21209 U.S.A.) is convenient, rapid and noninvasive, and allows objective assessment of sensory disturbance. This case is about the postherptic neuralgia patient assessed with $Neurometer^{(R)}$. From this case, we reviewed the pathophysiology and the treatment of PHN and recommend the assessment of pain intensity with $Neurometer^{(R)}$ as quantitative and objective method.

This study was conducted to evaluate the effect of plant number per hill (PNH) on growth and yield of foxtail millet in drained paddy fields. Crop growth, development, and yield in the field were examined for 2 years to assess the efficiency of proposed cropping system. The greatest culm length of 138 and 148 cm in the first and the second year, respectively, at the harvest stage was observed in plots with one plant per hill. The greatest culm diameter of 7.79 and 7.67 mm in the first and second year, respectively, was measured in plots with one plant per hill. The greatest tiller number of foxtail millet in plots with one plant per hill was 2.9 and 2.7 in the first and the second year, respectively. However, there was no significant difference between plots with four and five plant per hill. Among the measured yield components, the spike length and seed number per spike were one plant per hill in both years. The highest grain yield of foxtail millet ($324kg{\cdot}10a^{-1}$ and $333kg{\cdot}10a^{-1}$ in the first and second year, respectively) was obtained from plots with two plants por hill, followed by plots one, three, four, and five plants per hill.
